Photovoltaic installations on roofs or in fields is nothing unusual
it is probably not widely known that solar installations can also float
as more than 190 floating solar modules have been installed on the Mortkasee artificial lake in Lohsa
the Fraunhofer Institute for Solar Energy Systems (ISE) and Brandenburg University of Technology Cottbus-Senftenberg (BTU) investigates the extent to which floating solar islands can be implemented and operated in harmony with aquatic ecology
The project is being sponsored by the German Federal Ministry of Economic Affairs and Climate Action
The plant was officially inaugurated today in the presence of guests from the worlds of science
including representatives of the Saxon Ministry of Energy
Interested citizens also had the opportunity to learn about floating solar islands and the “PV2Float” research project.
mayor of the Lohsa municipality: “Originally created by flooding the Werminghoff opencast lignite mine
the Mortkasee artificial lake has become one of the first research sites for floating solar islands in Germany
This technology promises a higher power yield
since the cold water can have a positive impact on the efficiency of the solar modules
Another advantage is that previously unused mine lakes
which are not intended to be used for recreation
can be developed for green electricity generation
That offers major potential for the energy transition in Germany and here in our region.”
Three different floating solar islands have been installed on the Mortkasee
With a rated capacity of about 30 kilowatts each
but still provide important insights into the benefits of various technological solutions
future floating solar installations can be implemented in harmony with the environment
The research plant on the Mortkasee will operate until the end of 2027
Experienced partners from science and industry
Fraunhofer ISE and BTU Cottbus-Senftenberg are the three expert partners driving this research project forward
RWE has many years of experience in the construction and operation of utility-scale solar plants and already operates a floating photovoltaic plant on a former cooling water lake in the Netherlands
Fraunhofer ISE is Europe’s largest solar research institute
It develops solutions for floating photovoltaics and other integrated photovoltaic technologies
in addition to carrying out research into public acceptance of these technologies
BTU Cottbus-Senftenberg has extensive scientific expertise in the field of aquatic ecology

This study investigated the survival of Salmonella Senftenberg
Enterococcus faecalis and Clostridium sporogenes in sandy and clay loam textured soils when applied in bovine slurry or unpasteurised digestate
using laboratory based inoculation studies
when applied to grass in slurry and digestate
Bovine slurry and digestate were inoculated with the target bacteria to a final concentration of 106 log10 cfu/g or spores/g
thoroughly mixed into soil samples and incubated at 4°C or 14°C
Samples were removed periodically and the surviving cells enumerated using AOAC or equivalent methods
The loss of viability/culturability phase followed first order kinetics and T90 values ranged from 11.9 to 166.7 d at 4°C and from 6.0 to 156 d at 14°C
faecalis in sandy loam textured soil at 14°C (T90 values were significantly (P < 0.05) higher in slurry) the type of soil texture or application material (slurry or digestate) did not affect survival rates
12 grass covered micro-plots were prepared
innocua was applied in digestate and bovine slurry and rainfall was simulated at a target rate of ~11 mm per plot per h−1
Rainfall simulation (30 min) took place after 24
innocua strain using Brilliance Listeria agar supplemented with streptomycin sulphate (1,000 μg/ml) at 37°C for 48 h
Significantly (P < 0.05) lower counts were obtained in the run-off from digestate after 1
It was concluded that the type of organic fertiliser does not affect the bacterial survival rates in sandy and clay soils
faecalis in sandy loam textured soil at 14°C
bacteria may be retained better in the soil-digestate matrices during rainfall although additional research is required to further validate and provide the scientific basis for this observation
has been used as the main organic fertiliser on farmland
The primary objective of this study was to investigate bacterial pathogen survival in amended soil when either slurry or digestate was applied to the two most common soil types in Ireland using laboratory trials
A second study was also undertaken using rainfall simulation in a field trial that investigated the run-off rate of Listeria innocua when applied in slurry and digestate
A sandy loam (52% sand, 30% silt, 18% clay) and a clay loam (44% sand, 36% silt, 20% clay) soil (Brennan et al., 2012) were extracted from a permanent grassland site in Teagasc Johnstown Castle
Pebbles and small stones were removed by hand prior to portioning into samples
20 as “sandy loam” and 20 as “clay loam”
and 450 g of the appropriate soil sample was weighed into each
These boxes were sealed to prevent moisture loss and wrapped in aluminium foil to exclude light
Marked strains (streptomycin resistance 1,000 μg/ml) of Salmonella Senftenberg and Listeria
Enterococcus faecalis (NCTC 12697) and Clostridium sporogenes (DSM 767)
botulinum were obtained from the Teagasc culture collection held in the Teagasc Food Research Centre (Ashotwn
To prepare inocula for all target bacteria
a cryoprotective bead from frozen (−80°C) storage was streaked on Tryptone Soya Agar (TSA; Oxoid
Ireland) and incubated at 37°C for 24 h
A single colony from the resultant culture was aseptically mixed into 10 ml of Tryptone Soya Broth (TSB; Oxoid
Ireland) and incubated overnight at 37°C
The culture obtained was centrifuged at 8,014 × g (Centrifuge 5801 R
washed and resuspended in phosphate buffered saline (PBS; Oxoid
before resuspension in PBS and serially diluted to obtain cell concentrations of ~107 cfu/ml
Basingstoke UK) containing Anaerogen sachets (Oxoid
Ireland) and incubated at 37°C for 12 days
Spores were harvested by adding ~5 ml ice-cold sterile distilled water onto the surface of the CSA plates and agitating the surface of the agar with a sterile spreader to release spores from the agar
The suspension was then transferred to the next agar plate and the process repeated
The suspensions were then pooled in 50 ml tubes
centrifuged at 7,500 x g at 4°C for 10 min and washed with iced water
reducing the amount of liquid over the course of repeated cycles until a spore suspension of ~107 spores/ml (estimated by phase contrast microscopic examination) was obtained
The spore suspension was kept on ice throughout the entire harvesting process
This concentration was then confirmed by plating out on Columbia Blood Agar (CBA; Oxoid
Ireland) with 5% defibrinated horse blood (Cruinn diagnostics
Ireland) in anaerobic conditions as described above
The spore preparations (1 ml aliquots) were stored at −80°C
spore preparations were thawed at room temperature and heat treated at 80°C for 10 min to ensure the destruction of any vegetative cells
Fresh bovine slurry was obtained from a beef farm in County Meath
while digestate was obtained from a commercial AD plant in the east of Ireland that operates a mesophilic
using mainly food waste and slurry as feedstock materials
Twenty slurry samples (45 g) and twenty digestate samples (45 g) were prepared
four digestate and four slurry samples were inoculated in 5 ml PBS to give a concentration of 106 log10 cfu/g or spores/g
These samples were then thoroughly mixed manually using a sterile metal spoon into the previously prepared soil samples (450 g) to obtain four of each of the following combinations for each target bacterium: digestate plus sandy loam
The boxes were sealed and 2 of each combination incubated at 4 or 14°C (mean winter and summer temperatures respectively in Ireland) and sampled at times (t) = 0
Immediately prior to sampling the contents were thoroughly mixed again and 10 g removed
The pH and water activity (aw) of the soil samples was recorded at each sampling time-point
The pH was tested using a Eutech pH 150 probe (Thermo Scientific
The water activity was measured using an Aqualab Pre water activity metre (Labcell)
The metre was calibrated prior to use using a saturated solution of sodium chloride (KCl
aw = 0.984 ± 0.003 at 20°C)
monocytogenes were detected by adding 10 g of the soil sample to 90 ml of half strength Fraser Broth (Oxoid
Ireland) incubated overnight at 30°C
after which 0.1 ml of the resultant culture was added to 10 ml of full-strength Fraser broth (Oxoid
Ireland) and incubated at 37°C for 48 h
Duplicate 100 μl aliquots were plated on Listeria selective Oxford Agar (Oxoid
Ireland) with streptomycin sulphate (1,000 μg/ml) and characteristic colonies were considered to be L
10 g of soil sample was combined with 90 ml of BBL enterococcosel broth (Becton Dickinson
Ireland) and incubated at 37°C for 24 h before plating on Slanetz and Bartley Agar (Oxoid
incubated at 37°C for 24 h and 42°C for a further 24 h
sporogenes were detected by adding exactly 10 g of soil sample to 90 ml of Reinforced Clostridial Medium (RCM; Oxoid
Ireland) and incubating anaerobically as previously described at 37°C for 48 h
The enrichment culture was then plated on RCA in duplicate
and colonies confirmed using the qPCR method as described above
An outdoor study site of approximately 0.13 acres (526 m2) was selected at the Teagasc campus in Ashtown, Dublin (latitude 53.381590, longitude −6.336162) in the east of Ireland. The area has a temperate maritime climate, with an average annual temperature of 10.4°C and mean annual precipitation of 807.6 mm (Met Éireann, 2019)
The site was un-grazed and has been covered in a grass sward for many years with regular cutting but no slurry or other fertiliser treatment
The topography was slightly undulating with an average slope of ~10° along the length and 4° across the width
Listeria innocua was selected as the model organism as it is non-pathogenic
absent from the soil samples tested at the site and capable of surviving in soil
Exactly 12 micro-plots were prepared and randomly assigned to three groups (four plots each); (1) control (uninoculated); (2) L
The layout of the micro-plots (left) and a micro-plot with the aluminium frame and collection channel installed (right)
Three environmental L. innocua strains (isolated in fields grazed by cattle) were chosen from the Teagasc culture collection (designated M220, M344 and T1095) and streptomycin sulphate resistant variants of these strains (1,000 μg/ml) (Sigma Aldrich Ireland Ltd., Wicklow, Ireland) were prepared using the method of Blackburn and Davies (1994)
Marked strains were stored on cryoprotective beads at −80°C
a cryoprotective bead was streaked on TSA and incubated at 37°C for 24 h
after which a single colony was removed using a sterile loop
mixed into 10 ml of tryptone soya broth (TSB; Oxoid
The cultures obtained were centrifuged and washed three times with PBS (Oxoid
The 3 strains were then mixed to create a single L
innocua cocktail and serially diluted to give a final concentration of ~5 log10 cfu/g when inoculated into the slurry or digestate
which was performed as previously described
Inoculated slurry (left) and digestate (right) were applied to the microplots in linear rows
Rainfall was simulated using the Amsterdam drip type simulator (Bowyer-Bower and Burt, 1989) at a target rate of ~11 mm per plot per h−1, as used in other similar studies (Peyton et al., 2016)
The rainfall simulator formed droplets of median diameter of 2.3 mm
spaced 30 mm apart in a 1,000 × 500 × 8 mm perspex plate over a 0.5 m2 simulator area
To maximise control and to prevent runoff losses due to natural rainfall events
individual micro-plots were covered between treatments by large sheets of plastic
The first rainfall simulation (30 min) took place 24 h after treatment application thus representing a worst-case scenario that is contrary to current regulations
which stipulate that spreading of organic manure should not be carried out within 48 h of forecasted heavy rain [Nitrates Directive (91/676/EEC)]
The second was performed after 48 h (a scenario compliant with current regulations) the third after 14 d and the final rainfall simulation after 30 d
the last 50 ml and the runoff in between were collected separately and tested for the L
innocua strains using brilliance listeria agar (formerly Oxoid Chromogenic Listeria Agar (OCLA)
Ireland) supplemented with streptomycin sulphate (1,000 μl/g; Sigma Aldrich Ireland Ltd.
Soil samples were taken using a soil plugging tool on the day of the final rainfall simulation (30 d) and also after 58
The laboratory-based soil survival study was performed in duplicate and repeated on 3 separate occasions
Bacterial counts were converted into log10 cfu/g and the T90-values (the time required to achieve a 90% (1 log) reduction in the population) were determined by linear regression using Graphpad Prism 7 software (San Diego
considering each replicate Y-value as an individual point
Differences between slopes were examined using one-way ANOVA and Tukeys multiple comparison tests (GraphPad Prism 7.02)
Statistical significance was set at the 5% level (P < 0.05)
innocua counts were converted to log10 cfu/ml and differences in the mean counts in each sample type (first 50 ml
last 50 ml and overall) were analysed using one-way ANOVA (Graphpad Prism 7.02)
In the laboratory survival studies the pH of the sandy soil amended with slurry ranged from 5.9 to 7.0. The corresponding figures for sandy soil plus digestate, clay soil plus slurry and clay soil plus digestate were 5.3 to 6.9, 5.2 to 6.7 and 4.9 to 6.3 regardless of bacterial inoculum or storage temperature (Table 1). The aw in all soil-amendment combinations ranged from 0.95 to 1.0, regardless of storage temperature (also Table 1)
The pH and aw of the soil samples throughout the experiment
The decimal reduction curves are shown in Figures 3–7 and the T90 values are provided in Table 2
Growth was not detected and the decline phase followed first order kinetics for all of the target bacteria regardless of soil type
tailing was obtained at 4°C (slurry and digestate) with S
Senftenberg stored at 4°C were 21.3
sporogenes was marginal (1 log10 cfu/g or less over 124 d) and this is reflected in the T90 values
the T90 values were not significantly (P > 0.05) different regardless of the soil type or amendment (slurry or digestate) except for E
both in sandy soil where the T90 values obtained in slurry-amended soil were significantly higher than the corresponding values in digestate-treated soil

sporogenes over time in sandy (A) and clay (B) soils including with slurry at 4°C (■)
T90 values for the different bacteria applied in slurry and digestate to sandy loam and clay loam soils and stored at 4°C in the laboratory trials
At 14°C the T90 values for S. Senftenberg, E. coli O157:H7, L. monocytogenes, E. faecalis and C. sporogenes ranged from 12.4 to 20.8 d, 17.6 to 36.6 d, 6.0 to 12.2 d, 18.1 to 36.6 d and 106.5 to 156.0 d, respectively (Table 3)
For most pathogens soil type or application material had no effect with the exception of E
faecalis in sandy soils where significantly (P < 0.05) higher T90 values were obtained in slurry compared to digestate
T90 values for the different bacteria applied in slurry and digestate to sandy loam and clay loam soils and stored at 14°C in the laboratory trials
digestate and the soil in the field plots all tested negative for L
innocua (10 samples each) prior to commencement of the field trial
innocua in the inoculated slurry and digestate was 5 log10 cfu/g (data not shown)
In slurry and digestate this concentration decreased to 3.1 log10 cfu/g and 4.5 log10 cfu/g after 2 days
innocua population remained at this level until at least day 14
Thereafter it was not possible to test the slurry or digestate for L
innocua as these materials had become absorbed and mixed into the soil
Soil samples were therefore obtained after day 30 and tested
it was advised not to take soil samples before this stage as removal of soil plugs from the plot could influence the way in which the rainfall penetrated the soil and hence the concentrations of L
innocua was not detected in the soil samples taken throughout this experiment at 30
Rainfall was simulated at a rate of ~11 mm per plot h−1 for 30 min, the runoff collected and the bacterial concentration in the first 50 ml, last 50 ml and overall runoff measured. On the first day the L. innocua counts from slurry amended soil were 2.4, 2.0 and 2.0 log10 cfu/ml, respectively and the corresponding counts when applied in digestate were 1.9, 1.9 and 1.6 log10 cfu/ml (Table 4)
2.5 and 2.2 log10 cfu/ml for slurry and 2.0
On day 14 a similar pattern was observed (2.0
1.7 and 1.3 log10 cfu/ml for digestate) and again on day 30 (2.4
2.4 and 1.7 log10 cfu/ml for slurry and 1.6
1.7 and below the level of detection for digestate)
innocua counts were obtained when applied in digestate on day 1 (first 50 ml and entire sample)
innocua in leachate during rainfall simulation from inoculated slurry and digestate
These bacteria generally survived for up to 1 month when applied to both sandy and clay soils
Our findings therefore support the hypothesis that Salmonella spp
die-off within approximately 4 weeks when applied to land
sporogenes inoculated into soil in field trials declined by <0.7 log after 16 months
we hypothesise that rainwater falling on freshly applied digestate (as compared to slurry) will have lower penetration and reduced ability to remove bacteria in the resultant run-off
over time the permeability of the digestate amended soil may be less than slurry-treated pastures
reducing leeching of any surviving bacteria into ground water
unpasteurised digestate) does not affect survival rates of the bacteria tested in soil
a higher proportion of bacteria may be retained in the soil-digestate matrix during periods of rainfall
thereby reducing the risk of ground and surface water contamination

Food Poisoning Outbreaks and Litigation: Surveillance and Analysis
along with CDC and state and local partners
are investigating a multistate outbreak of Salmonella Senftenberg infections linked to certain Jif peanut butter products produced at the J.M
There have been a total of 14 illnesses with 2 hospitalization in the following states: Arkansas (1)
Product distribution was nationwide and has been confirmed for states listed
but product could have been distributed further
but perhaps perplexing fact that needs further answers:
FDA conducted Whole Genome Sequencing (WGS) analysis on an environmental sample collected at the Lexington
The analysis shows that this 2010 environmental sample matches the strain causing illnesses in this current outbreak
Smucker Company has voluntarily recalled certain Jif brand peanut butter products that have the lot code numbers between 1274425 – 2140425 manufactured in Lexington

Breaking news for everyone's consumption
a total of 16 people infected with the outbreak strain of Salmonella Senftenberg have been reported from 12 states: Arkansas (1)
for every one person who is a stool-culture confirmed positive victim of Salmonella in the United States
there is a multiple of 38.5 who are also sick but remain uncounted
“FoodNet estimate of the burden of illness caused by nontyphoidal Salmonella infections in the United States,” Clinical Infectious Diseases 2004; 38 (Suppl 3): S127-34)
Illnesses started on dates ranging from February 19
Sick people range in age from less than one to 85 years
The true number of sick people in an outbreak is likely much higher than the number reported
and the outbreak may not be limited to the states with known illnesses
This is because many people recover without medical care and are not tested for Salmonella
recent illnesses may not yet be reported as it usually takes 2 to 4 weeks to determine if a sick person is part of an outbreak
State and local public health officials are interviewing people about the foods they ate in the week before they got sick
Of the nine sick people with brand information
all nine reported eating Jif brand peanut butter

Stay up to date on food recalls and outbreaks to avoid getting sick from eating contaminated food
CDC, public health and regulatory officials in several states, and the U.S. Food and Drug Administration (FDA) collected different types of data to investigate a multistate outbreak of Salmonella Senftenberg infections
Epidemiologic and laboratory data showed that Jif brand peanut butter made people sick
As of July 27, 2022, a total of 21 people infected with the outbreak strain of Salmonella Senftenberg were reported from 17 states (see map). Illnesses started on dates ranging from February 20, 2022, through May 24, 2022 (see timeline)
Sick people ranged in age from less than one to 85 years
State and local public health officials interviewed people about the foods they ate in the week before they got sick. Of the 13 people interviewed, 13 (100%) reported eating peanut butter in the week before they got sick. This percentage was significantly higher than results from a survey of healthy people
in which 57% of respondents reported eating any peanut butter in the week before they were interviewed
This suggests that people in this outbreak got sick from eating peanut butter
All 13 people reported eating Jif brand peanut butter specifically
Public health investigators used the PulseNet system to identify illnesses that were part of this outbreak. CDC PulseNet manages a national database of DNA fingerprints of bacteria that cause foodborne illnesses. DNA fingerprinting is performed on bacteria using a method called whole genome sequencing (WGS)
WGS showed that bacteria from sick people's samples were closely related genetically
This means that people in this outbreak likely got sick from the same food
FDA conducted WGS analysis on an environmental sample collected at the Lexington
The analysis shows that this 2010 environmental sample was closely related genetically to the outbreak strain
WGS analysis of bacteria from 21 people's samples did not predict resistance to any antibiotics. Standard antibiotic susceptibility testing by CDC's National Antimicrobial Resistance Monitoring System (NARMS) laboratory was underway at the time this investigation closed

Providing Insight on Food Poisoning Outbreaks & Litigation
The key points of this warning letter are in BOLD below:
Food and Drug Administration (FDA) and the Kentucky Cabinet for Health and Family Services Food Safety Branch (CHFS-FSB) jointly inspected your manufacturing facility located at 767 Winchester Road
The inspection was initiated as part of a multistate foodborne outbreak investigation of Salmonella Senftenberg (S
Senftenberg) illnesses linked to your ready-to-eat (RTE) peanut butter
According to the Centers for Disease Control and Prevention (CDC)
21 people from 17 states were infected with the outbreak strain of S
your firm recalled all peanut butter manufactured at this facility from October 1
due to potential contamination with Salmonella
that peanut butter manufactured at your facility was the source of this multistate S
the evidence establishes that you introduced adulterated peanut butter into interstate commerce as prohibited by section 301(a) of the Federal Food
We received your responses to the FDA 483 dated July 1
describing the corrective actions taken and planned by your firm
including training records associated with your implemented corrective actions
After reviewing the inspectional findings and your responses
we are issuing this letter to advise you of FDA’s continuing concerns and provide detailed information describing the findings at your facility
Multistate Outbreak of Salmonella Senftenberg linked to Jif Brand Peanut Butter:
During routine monitoring of the whole genome sequencing (WGS) National Center for Bioinformatics database
FDA identified five recent 2022 clinical isolates (samples collected from ill people) which matched over one hundred third-party peanut butter and environmental isolates from Kentucky collected from 2014 to 2017. Shortly thereafter
FDA and CDC began investigating a multistate outbreak of Salmonella infections
five out of five patients who were interviewed
reported peanut butter exposure with four specifically reporting consuming Jif brand peanut butter. FDA reviewed information from inspections and identified a 2010 FDA environmental sample of S
WGS was conducted on the 2010 environmental sample
and it was found to match the growing cluster of S
Senftenberg clinical isolates from the outbreak of Salmonella infections and the peanut butter and environmental isolates from Kentucky. The presence of the same S
Senftenberg strain in your facility since 2010
we notified you of these findings via teleconference
you initiated a voluntary recall of Jif brand peanut butter
CDC deployed a supplemental peanut butter focused questionnaire to identify possible clinical exposures
this outbreak included 21 cases from 17 states
all reported Jif brand peanut butter exposure (100%)
laboratory and traceback data show that you introduced adulterated peanut butter into interstate commerce as prohibited by section 301(a) of the Act (21 U.S.C
the evidence supports that the peanut butter responsible for this outbreak was manufactured in your Lexington
Your finished product testing records from January 1
indicate that you detected Salmonella in your RTE peanut butter on numerous occasions
and that your corrective actions were not sufficient to address the root cause of the contamination
you identified a leak in the air intake vent of the cooling chamber of Roaster (b)(4)
as a source of water entering your equipment
and stated you immediately repaired the vent
you detected Salmonella in (b)(4) of the (b)(4) lots on Line (b)(4) ((b)(4)
and (b)(4)) using your standard (b)(4) samples per lot sampling program
you “collect[ed] [and tested] (b)(4) samples ((b)(4)sample composites) from the lot[s] produced immediately prior to and after the product that tested positive.” After testing (b)(4) lots that initially tested negative for Salmonella
you identified two additional positive lots:
you detected Salmonella in a (b)(4) lot on Line (b)(4) using your standard (b)(4) samples per lot sampling program
after testing (b)(4) lots that initially tested negative for Salmonella you identified additional positive lots:
You indicated that “[e]ven when the additional samples test negative
we destroy all (b)(4) production lots to provide further assurance we have bracketed and eliminated any potential contamination.” However
your positive test results for lots for which Salmonella was previously not detected show the limitations of reliance on your testing program to identify contamination as a way to prevent contaminated products from reaching consumers
Senftenberg outbreak shows that neither your corrective actions nor your finished product testing was adequate to prevent contaminated product from reaching consumers and causing illnesses
Senftenberg was likely due in part to Salmonella introduced to your production process through cooling air supply vents that were installed incorrectly on Roaster (b)(4) on December 10
allowing unfiltered air and a small amount of rainwater to enter the cooling section of the roaster where the peanuts are RTE
Preventing water in dry processing environments for low moisture foods is essential to control environmental pathogens such as Salmonella
you stated that you updated your finished product testing procedures to include a “(b)(4) Hold” in the event a single positive result is detected in your RTE peanut butter
This (b)(4) Hold includes holding “(b)(4) Lots” produced (b)(4) hours before and (b)(4) hours after the affected (i.e.
positive) lot and performing further testing using (b)(4) samples from only the (b)(4) lots on “each extreme of the bracketed window” (i.e.
only the (b)(4) or (b)(4) lot on either end of the held product)
You stated that “this conservative approach provides a safety factor to ensure any potential contamination is included [in the held product].”
We are concerned that your use of this approach in response to a contamination event would not ensure all affected product would be identified and prevented from entering commerce
We are not aware of any data or scientific rationale to support how your (b)(4)Hold would be an effective approach to identify all product affected by a contamination event in your continuous production of RTE peanut butter
we ask that you provide support for your approach
Hazard Analysis and Risk-Based Preventive Controls (21 CFR Part 117
You did not identify and evaluate the hazard of contamination with environmental pathogens
as a known or reasonably foreseeable hazard to determine whether it requires a preventive control
“Hazard Analysis – Process for the ‘Jif Lexington’” plant
did not consider the hazard of recontamination with environmental pathogens
at post-roasting processing steps from blanching to sorting and milling (including (b)(4))
In-process RTE peanuts are exposed to the environment at these steps
and the food does not receive further treatment or otherwise include a control measure (such as a formulation lethal to the pathogen) that would significantly minimize the pathogen
response discussed actions your facility has taken to address the deficiencies with your food safety plan
including adding environmental recontamination with Salmonella as a hazard requiring a sanitation preventive control at all steps where RTE product is exposed to the environment and will not receive an additional kill-step
you did not provide a revised hazard analysis or food safety plan for our evaluation
we request that you provide your current food safety plan (including your hazard analysis)
Your corrective action procedures did not ensure appropriate action was taken
to reduce the likelihood that environmental contamination will recur
when you detected Salmonella in your facility’s environment
you indicated that your environmental monitoring program included collecting (b)(4) environmental samples from zones (b)(4)
and (b)(4) located throughout the manufacturing and packaging areas of the facility
All samples were sent to your third-party testing laboratory and analyzed for Listeria monocytogenes
You stated that your corrective actions for positive samples included increased cleaning and sanitizing to the subject area until (b)(4) negatives are obtained.Your environmental monitoring records from July 24
revealed four Salmonella positive environmental swabs located at roaster (b)(4)
floor of the entrance to the blanch nut tank rooms (b)(4) and (b)(4)
and the floor broom in the roaster (b)(4)
You determined that the root causes for each Salmonella positive environmental swab were roof leaks or increased foot traffic during repairs in response to roof leaks
and you took immediate action to repair roof leaks and to correct foot traffic issues
Your records indicate that you suspended production until you could clean and sanitize the areas and take other corrective actions
such as adding (b)(4) and replacing utensils
Your environmental monitoring records from 2021 revealed five Salmonella positive environmental swabs in your facility on July 6
These Salmonella positive swabs were found on the floors near your blanch nut tank rooms
the stairs at the top level of the nut house (b)(4)
and the stairs leading to platform “(b)(4)”
The detection of Salmonella in your facility in 5 locations in 2021
many of which were similar to locations where you detected Salmonella in 2018 and 2019
show that your corrective action procedures in response to environmental contamination in 2018 and 2019 were not sufficient to reduce the likelihood that environmental contamination would recur
you indicated that you conducted root cause investigations on the 2021 Salmonella findings in your facility
and you implemented corrective actions consistent with your environmental monitoring procedures
the outcomes of these investigations (e.g.
your root cause determinations) were not provided in your response
This letter is not intended to be an all-inclusive statement of violations that may exist in connection with your products
You are responsible for investigating and determining the causes of any violations and for preventing their recurrence or the occurrence of other violations
It is your responsibility to ensure that your firm complies with all requirements of federal law
This letter notifies you of our concerns and provides you an opportunity to address them
Failure to adequately address this matter may result in legal action including
We are concerned that the history of contamination events associated with water in your facility and results from the WGS database suggest that Salmonella may be resident within your production facility. As an example of the continuing problems with water in the facility
measuring approximately 4 feet by 8 feet in the bottom of cooling zone (b)(4) in Roaster (b)(4) and a puddle of water measuring approximately 4 inches by 4 inches in the bottom of cooling zone (b)(4) in Roaster (b)(4)
you collected environmental swabs from Roaster (b)(4)
which were found to be indicative of microbial growth
Your investigation found a defective flange on the zone (b)(4) cooler inlet of Roaster (b)(4)
which allowed rainwater and unfiltered air to enter the roaster’s cooling zones and contact the roasted peanuts after the roasting/kill step
Your corrective actions included repairing the defective flange and cleaning and sanitizing the roasters
you stated that you will verify that there are no conditions conducive for bacteria growth on equipment due to the presence of water/moisture before beginning a production run
you provided your “Right to Run (b)(4)Inspection” procedure which you state is a supplement to the overall Plant Food Safety program to ensure the plant does not continue production with critical food safety risks present (i.e.
“external conducive conditions related to water penetration and other adverse environmental factors that could yield product contamination”)
You also implemented (b)(4) inspections and sanitation of the roofs and ceilings according to your Master Sanitation Schedule
While these procedures may help to identify events which would introduce water into your processing environment
constant vigilance is needed to ensure water does not become a source or route of cross-contamination in your dry processing environment
to prevent Salmonella from spreading in your facility and adulterating your products
it is essential to identify the areas in your food manufacturing plant where Salmonella survive and take corrective actions as necessary to eradicate the organism
we recommend that you consider incorporating WGS as a tool to investigate pathogen isolates obtained in your environmental monitoring program and/or your finished product testing program
The use of WGS to analyze and investigate any pathogen isolated from your production environment or RTE peanut butter will provide the most complete information available to identify and implement appropriate and effective corrective actions
including steps to prevent the contamination from recurring and steps to ensure contaminated product does not enter commerce
we note that during the inspection and in your response dated July 1
you stated that on “very rare instances you find Salmonella in finished product when a Salmonella organism survives our validated thermal process.” Specifically
you stated this in reference to the detection of Salmonella in your peanut butter produced on October 22
You added that you have a “robust finished product testing program specifically because of this possibility
such as the roasters that are validated to deliver over a (b)(4) kill
does not eliminate the potential that Salmonella could survive the roasting process on rare occasion.” We evaluated your roasting process parameters during the inspection and disagree with your position that a properly validated and implemented process control at your peanut roasting step would allow for the survival of Salmonella such that the pathogen would be detected in your finished product because it survived the roasting step
response that after detecting Salmonella in your RTE peanut butter on February 4
you used a (b)(4) to remove peanut butter from the lines between the (b)(4) to the (b)(4). (b)(4) piping and other equipment used to process peanut butter contaminated with Salmonella
although effective at removing large amounts of peanut butter from the equipment
are not an effective means of eliminating possible Salmonella contamination from that equipment

and Cosmetic Act in 1938 in reaction to growing public safety demands
The primary goal of the Act was to protect the health and safety of the public by preventing deleterious
adulterated or misbranded articles from entering interstate commerce
a food product is deemed “adulterated” if the food was “prepared
or held under insanitary conditions whereby it may have become contaminated with filth
or whereby it may have been rendered injurious to health.” A food product is also considered “adulterated” if it bears or contains any poisonous or deleterious substance
and the recently signed Food Safety Modernization Act
stand today as the primary means by which the federal government enforces food safety standards
Chapter III of the Act addresses prohibited acts
subjecting violators to both civil and criminal liability
Provisions for criminal sanctions are clear:
Felony violations include adulterating or misbranding a food
and putting an adulterated or misbranded food
Any person who commits a prohibited act violates the FDCA
A person committing a prohibited act “with the intent to defraud or mislead” is guilty of a felony punishable by years in jail and millions in fines or both
does not require proof of fraudulent intent
a person may be convicted if he or she held a position of responsibility or authority in a firm such that the person could have prevented the violation
Convictions under the misdemeanor provisions are punishable by not more than one year or fined not more than $250,000
if you are a producer of food and knowingly or not manufacturer and sell adulterated food
you can (and should) face fines and jail time

From Bethlehem and Frankfurt to London and Boston
the surging coronavirus put a damper on Christmas Eve for a second year
forcing churches to cancel or scale back services and disrupting travel plans and family gatherings
Drummers and bagpipers marched through Bethlehem — the town where Christians believe Jesus was born — to smaller than usual crowds after new Israeli travel restrictions meant to slow the highly contagious omicron variant kept international tourists away
a line wound halfway around Cologne's massive cathedral
not for midnight Mass but for vaccinations
The offer of shots was an expression of "care for one's neighbor" that was consistent with the message of Christmas
cathedral provost Guido Assmann told the DPA news agency
people weary from nearly two years of lockdowns and other restrictions searched for ways to enjoy some of the holiday rituals safely
"We can't let the virus take our lives from us when we're healthy," said Rosalia Lopes
a retired Portuguese government worker who was doing some last-minute shopping in the coastal town of Cascais
She said she and her family were exhausted by the pandemic and determined to go ahead with their celebrations with the help of vaccines and booster shots
rapid home tests and mask-wearing in public
She planned a traditional Portuguese Christmas Eve dinner of baked cod
many doing so as a precaution before traveling to reunite with family
But holiday travel was dealt a blow when major airlines canceled hundreds of flights, in part because of staff shortages largely tied to omicron.
In Britain, where the coronavirus variant is ripping through the population, some houses of worship hoped to press on.
At St. Paul's Old Ford, an Anglican church in East London, priests planned to hold services on Christmas Eve and Christmas Day. But to protect parishioners, the church called off its Nativity play.
Numerous churches in the U.S. canceled in-person services, including Washington National Cathedral in the nation's capital and historic Old South Church in Boston. Others planned outdoor celebrations or a mix of online and in-person worship.
In Germany, churchgoers faced a thicket of health restrictions and limits on attendance. Some had to show proof of vaccination or testing.
Frankfurt's cathedral, which can hold 1,200 people, offered only 137 socially distanced spaces, all of which were booked days in advance. Singing was allowed only through masks.
People in the Netherlands tried to make the best of the holiday, despite living under one of the strictest lockdowns in Europe. All nonessential shops were closed, including bars and restaurants, and home visits were limited to two people per day, four on Christmas.
"We are just meeting with some small groups of family for the next few days," Marloes Jansen, who was waiting in line to buy the traditional Dutch kerststol, a Christmas bread with fruits and nuts.
A glitch in a computerized appointment system prevented scores of people from scheduling COVID-19 tests and undermined the government's efforts to administer booster shots in a country already lagging far behind its neighbors.
In France, some visited loved ones in the hospital. In the Mediterranean city of Marseille, the intensive care unit at La Timone Hospital has been taking in more and more COVID-19 patients in recent days.
Amelie Khayat has been paying daily visits to her husband, Ludo, 41, who is recovering from spending 24 days in a coma and on a breathing machine.
They touched their heads together as she sat on his bed, and now that he is strong enough to stand, he got up to give her a farewell hug, as a medical worker put final decorations on the ICU Christmas tree.
Parisians lined up at chocolate shops, farmers' markets and testing centers. France has posted record numbers of daily COVID-19 infections, and hospitalizations have been rising, but the government has held off on imposing curfews or closings during the holidays.
In Antwerp, Belgium, Christmas trees hung upside down from windows in a protest against the closing of cultural venues.
In Bethlehem, the scene was much more festive than it was a year ago, when musicians marched through empty streets. This year, hundreds of people gathered in Manger Square as bagpipe-and-drum units streamed through.
Before the pandemic, Bethlehem would host thousands of Christian pilgrims from around the world. The lack of visitors has hit the city's hotels, restaurants and gift shops especially hard.

In the USA, Salmonella enterica subspecies enterica serovar Senftenberg is among the top five serovars isolated from food and the top 11 serovars isolated from clinically ill animals. Human infections are associated with exposure to farm environments or contaminated food. The objective of this study was to characterize S. Senftenberg isolates from production animals by analyzing phenotypic antimicrobial resistance profiles, genomic features and phylogeny.
This study provided antimicrobial susceptibility and genomic characteristics of S. Senftenberg clinical isolates from production animals in the USA during 2014 to 2017. This study will serve as a base for future studies focused on the phenotypic and molecular antimicrobial characterization of S. Senftenberg isolates in animals. Monitoring of antimicrobial resistance to detect emergence of multidrug-resistant strains is critical.

Salmonella enterica subspecies enterica serovar Senftenberg is among the top five serovars isolated from food and the top 11 serovars isolated from clinically ill animals
Human infections are associated with exposure to farm environments or contaminated food
The objective of this study was to characterize S
Senftenberg isolates from production animals by analyzing phenotypic antimicrobial resistance profiles
Salmonella Senftenberg isolates (n = 94) from 20 US states were selected from NVSL submissions (2014–2017)
Resistance genotypes were determined using whole genome sequencing analysis with AMRFinder and the NCBI and ResFinder databases with ABRicate
Plasmids were detected using PlasmidFinder
Integrons were detected using IntFinder and manual alignment with reference genes
Multilocus-sequence-typing (MLST) was determined using ABRicate with PubMLST database
60.6% were resistant to at least one antimicrobial and 39.4% showed multidrug resistance
The most prevalent resistance findings were for streptomycin (44.7%)
ampicillin (36.2%) and sulfisoxazole (32.9%)
The most commonly found antimicrobial resistance genes were aac(6′)-Iaa (100%)
aph(3″)-Ib and aph(6)-Id (29.8%) for aminoglycosides
followed by blaTEM-1 (26.6%) for penicillins
sul1 (25.5%) and sul2 (23.4%) for sulfonamides and tetA (23.4%) for tetracyclines
Quinolone-resistant isolates presented mutations in gyrA and/or parC genes
Class 1 integrons were found in 37 isolates
Thirty-six plasmid types were identified among 77.7% of the isolates
Phylogenetic analysis identified two distinct lineages of S
Senftenberg that correlated with the MLST results
Isolates were classified into two distinct sequence types (ST): ST14 (97.9%) and ST 185 (2.1%)
The diversity of this serotype suggests multiple introductions into animal populations from outside sources
This study provided antimicrobial susceptibility and genomic characteristics of S
Senftenberg clinical isolates from production animals in the USA during 2014 to 2017
This study will serve as a base for future studies focused on the phenotypic and molecular antimicrobial characterization of S
Monitoring of antimicrobial resistance to detect emergence of multidrug-resistant strains is critical
Since Salmonella is associated with outbreaks of foodborne disease, MDR strains pose a risk to public health because of the potential for treatment failures (Nair et al., 2018)
Few studies exist on the antimicrobial susceptibility and genetic diversity of Salmonella serovar Senftenberg of animal origin
Among all Salmonella serotyping submissions received at the NVSL from January 1
Senftenberg ranked number eight during 2014 and number 10 during 2015 among clinical isolates
2016 and number two during 2017 among non-clinical isolates
The objective of this study was to compare phenotypic and genomic resistance data
Senftenberg diagnostic isolates recovered from poultry
and cattle in the USA between 2014 and 2017
and to provide useful retrospective information for future studies on S
Senftenberg isolates from swine (n = 50)
poultry (n = 24) and cattle (n = 20) were selected from the National Veterinary Services Laboratories (NVSL) Salmonella repository isolates archived at room temperature on nutrient agar slants
Samples came from 20 US States (IA = 20
Isolates were selected from samples that were submitted to the NVSL for Salmonella serotyping, confirmed by classical (Grimont and Weill, 2007) and molecular typing using Luminex xMAP® technology (Dunbar et al., 2015)
The dataset was initially limited to one sample per year per owner
If more than the targeted number of isolates were available
a randomly selected subset of isolates was chosen
The data was then de-identified to remove information other than the animal species
and sample type and assigned a unique identifier
Salmonella was confirmed using Biotyper software with an autoflex speed™ MALDI-TOF instrument (Bruker Daltonics
Isolate sequences are publicly available in the NCBI BioProject PRJNA785813
Overall, the highest percentage of resistance was found to the following antimicrobials: streptomycin (44.7%), tetracycline (42.6%), ampicillin (36.2%) and sulfisoxazole (32.9%) (Figure 1)
Senftenberg isolates were susceptible to meropenem
Antimicrobial resistance rates of the 94 Salmonella Senftenberg isolates
For ciprofloxacin (CIP) isolates categorized as intermediate (MIC 0.12 to 0.5 μg/mL) or resistant (MIC ≥ 1 μg/mL) were defined as having decreased susceptibility to CIP with a MIC ≥ 0.12 μg/mL
Senftenberg isolates displaying antimicrobial resistance
Antimicrobial resistance genes are shown in Table 1
The most commonly observed was the aminoglycoside acetyltransferase aac(6′)-Iaa gene
and the aminoglycoside phosphotransferase aph(3″)-Ib and aph(6)-Id genes seen together in 29.8% (n = 28) of isolates
a dihydropteroate synthase that is linked to other resistance genes of class 1 integrons and confers resistance to sulfonamides
was found in 25.5% (n = 24) of the isolates; and the sul2 gene was observed in 23.4% (n = 22) of the isolates
Resistance to tetracycline was due to the presence of the tetA gene that encodes a tetracycline efflux pump
and it was observed in 23.4% (n = 22) of the isolates
was the most prevalent beta-lactamase gene (26.6%) conferring resistance to penicillins (ampicillin); but blaCMY-2
was the most prevalent beta-lactamase gene (14.9%) against penicillins plus inhibitors (amoxicillin + clavulanic acid) and cephalosporins (cefoxitin
The class A extended spectrum beta-lactamases (ESBLs) encoded by the blaSHV-12 gene were found in five isolates from swine
In addition to aph(3″)-Ib and aph(6)-Id genes
other resistance genes were observed that convey resistance to aminoglycosides
including several integron-encoded aminoglycoside nucleotidyltransferases such as aadA1
Resistance genes for gentamicin included several aminoglycoside acetyltransferases encoded by: aac(6′)-Ib4 gene in 9.6%; aac(6′)-Ib
aac(3)-VIa in 7.4%; and aac(3)-IVa in 4.3%
The nucleotidyltransferase ant(2″)-la gene was found in 7.4%
and the methyltransferase armA gene in one isolate
Six genes conferring resistance to macrolides were found in 13.8% of isolates; the ereA gene that encodes an erythromycin esterase was the most frequently identified in 6 isolates
followed by the mphA gene that encodes a macrolide 2′-phosphotransferase in 3 isolates
Several resistance genes were found for chloramphenicol; the most frequent was the plasmid or transposon-encoded chloramphenicol exporter floR
Additional chloramphenicol exporter genes found in lower frequency were cmlA5 (3.4%) and cmlA1 (1.1%) genes
Quinolone-resistance genes were detected in 12 isolates; the most frequent gene was qnrB2
a plasmid-mediated quinolone resistance protein
and others in lower frequency: qnrB19 in 3.4%
qnrB6 in 1.1% and aac(6′)-lb-cr in 1.1% of isolates
The aac(6′)-lb-cr gene doubly confers resistance to aminoglycoside and fluoroquinolone antibiotics through fluoroquinolone-acetylating activity
which is often carried in the conserved sequence (3′ CS) of a class 1 integron
Ten of these integrons were identified as In48
and carried a resistant gene cassette (aac(6)-Ib)
positive for Intl1 and carried a dfrA15 cassette
Seventeen isolates exhibited decreased resistance to ciprofloxacin (MIC ≥0.12 μg/ml)
Fluoroquinolone-resistance genes were identified in 11 of those isolates
The remaining six isolates did not harbor any resistance genes; however
point mutations were detected in these six isolates
Four isolates showed a point mutation in the gyrA (D87N) and parC (T57S) genes
and the other two isolates had a mutation in only the parC (T57S) gene
Five isolates exhibited resistance to nalidixic acid without any specific quinolone resistance gene present
but in four of these five isolates there were point mutations in gyrA and parC genes and in only the parC gene for one isolate
all the isolates showed mutations in the parC gene regardless of phenotypic resistance to nalidixic acid or ciprofloxacin
The association of antimicrobial susceptibility with antimicrobial resistance genes is shown in Table 3
The least discordance among the animal isolates was seen for β-lactams and the most were seen for phenicols
Antimicrobial resistance varied across isolates from different animal species. Isolates from all animal species showed susceptibility to MEM. Isolates from cattle and swine showed resistance to all other antimicrobials in variable frequency. All poultry isolates were susceptible to AMC, FOX, CRO, AZM, CIP and NAL (Figure 2)
Antimicrobial resistance for each drug among cattle
The percentage of isolates that were MDR varied among the different animal species
Sixty percent (30/50) of the isolates from swine were MDR; three were resistant to 12 antimicrobials and one was resistant to 13 antimicrobials
Antimicrobial resistance genes are often encoded on mobile genetic elements such as plasmids
36 plasmid types were identified in 73 (77.7%) isolates
Plasmid profiles differed among each animal species
Thirty-four different plasmids were found among swine isolates
14 among poultry isolates and 10 among cattle isolates
found in 60.6% of the study isolates: n = 20 (83.3%) in poultry
n = 31 (62%) in swine and n = 6 (30%) in cattle isolates
IncHI2A and IncHI2 in 12.8% of isolates (75% in swine isolates) and others in lower frequency
The presence of the mcr-9.1 colistin resistance gene and the presence of the ESBL blaSHV-12 gene were correlated with the presence of the two plasmids IncHI2A and IncHI2
Isolates were classified into two distinct sequence types (ST) based on MLST analysis from genome sequences
Ninety-two isolates (97.9%) belonged to ST14 and only two isolates (2.1%) belonged to ST185
ST14 and ST185 share no common alleles at any of the seven loci that define an allelic profile or ST by MLST analysis
S. Senftenberg is a polyphyletic serovar. Phylogenetic analysis identified two distinct lineages of S. Senftenberg in this study that correlated with the MLST results. The smaller clade corresponded to ST185, and the majority of isolates corresponded to ST14 (Supplementary Figure S1)
The addition of closely related representative serotypes from NCBI shows that the two MLST types observed in this study are entirely distinct lineages; and in addition
Senftenberg which was not observed in this study
This suggests that the serotype designation may not represent a good indicator of the genetic relationships between strains
The well differentiated cluster within the ST14 group showed an average distance of 30.8 SNPs (range of 22 to 44 SNP) from a common ancestor
A previous study of animal and human isolates in the USA (Stepan et al., 2011) showed that human strains of S
Senftenberg were susceptible to all of the antimicrobials tested
whereas the animal isolates showed a range of resistance
with most isolates being resistant to two or more antimicrobials
In this study, isolates from swine and cattle showed resistance to 13 antimicrobials in different frequencies, whereas poultry isolates showed resistance to only six antimicrobials tested; these results differ from Stepan et al. (Stepan et al., 2011) where the rate of resistance to antimicrobials was similar across the host species (swine
Other important findings of our study were the presence of three isolates from swine resistant to 12 antibiotics and one resistant to 13 antibiotics
Variations were in the Salmonella pathogenicity island (SPI)-1 and SPI-2 that exhibited distinct biochemical and phenotypic signatures
Clade 1 isolates comprised three sequence types: ST185
being single or double locus variants relative to one another
the two distinct lineages also differ in the ST
Even though there are other STs observed in other datasets
these STs are single or double locus variants relative to one another
We observed that there are other serotypes that fall between the two lineages
indicating that they are two completely independent lineages in S
Senftenberg and not a single serotype that diverged over time
As may be expected based on the phylogenetic diversity, resistance patterns among S. Senftenberg isolates differ significantly among isolates. In our study, the most common resistance profile was AMP, GEN, STR (n = 5 isolates), whereas Stepan et al. (Stepan et al., 2011) found STR
SXT the most common (n = 4 isolates)
In our study sul1 and sul2 genes were also associated with sulfonamide resistance
and floR gene the most prevalent associated with chloramphenicol resistance
60% (n = 30) of isolates from swine origin showed MDR
and in 70% (n = 21) of these isolates we observed the presence of a class 1 integron
The number of plasmids did not correlate with MDR or XDR
as we found isolates with as many as seven or eight plasmids that were resistant to only one or two antibiotics and isolates with only one plasmid with resistance to seven antibiotics
Senftenberg isolates carrying the qacEΔ1 gene were MDR
This study provided an analysis of retrospective data of Salmonella Senftenberg and information about the antimicrobial susceptibility and genomic characteristics in diagnostic isolates of S
Senftenberg from production animals in the USA
This study reports the genotype-phenotype homogeneity and variability of S
to cause disease in various animal species
to be a potential risk of transmission to humans and to harbor resistance to critical antimicrobial and mobile elements capable of dissemination of acquired resistance genes makes S
Senftenberg an important public health pathogen
In this study we found that 39.4% of the isolates tested displayed multidrug resistance
and four isolates were potentially extensively drug resistant
This has important implications for both animal and human health
due to possible transmission of MDR bacteria from animal to animal or animal to human (zoonotic)
and the difficulty in treatment of resistant bacteria
These data highlight the need to strengthen surveillance to detect the prevalence and transmission of nontyphoidal Salmonella species because of the emergence of MDR strains
It is critical to identify the emergence of these strains as early as possible to avoid further dissemination and establish control procedures
This data is useful for future studies on S
Senftenberg and to further understand this pathogen as few studies exist on the antimicrobial susceptibility

ASTOC Architects & Planners have won first prize in the international competition for the new harbor and pier in Senftenberg, Germany
The purpose of the competition was to design the new harbour on the basis of an urban study
The integration of the lake into the 70 square kilometers of navigable interconnection will further develop the tourist infrastructure of the region “Lausitzer Seenland”
The new pier plays an important role as a new landmark for the region
The project consists of port facilities as well as a restaurant with meeting rooms overlooking the harbor

Topeka-area grocery stores are among those to pull Jif products from the shelves after J.B
issued a recall because of a possible Salmonella Senftenberg contamination
Products affected have lot code numbers 1274425 through 2140425, and digits ending with 425
The numbers can be found by the best-if-used-by date
Missouri and Arkansas are among 12 states that have reported 14 people have been sickened
Two were hospitalized. Salmonella Senftenberg can cause outbreaks of gastroenteritis and invasive intestinal infections
Epidemiologic and laboratory data suggest that some Jif brand peanut butters and natural honey may be to blame
according to the Centers for Disease Control and Prevention
How consumers can get reimbursed for peanut butter purchaseTerry Fleer
said his store pulled the products from the shelves
He advised consumers on how to get reimbursed at the store where they purchased the product
they could take it back to their stores," Fleer said. "They have to have a receipt."
Fleer said consumers may be able to return unopened supplies for reimbursement to other stores without receipts
but his store's policy is not to accept them
consumers may be unable to receive compensation
Fleer suggested calling the phone number provided on the items for more information
"There's a number on those products you'd call that have a hotline that you can talk to," he said
"There's somebody there to talk to you or answer some questions for you."
Topeka's Salvation Army and the Topeka Rescue Mission weren't affected by the recall
"Healthy persons infected with Salmonella often experience fever
vomiting and abdominal pain," according to Smucker's recall announcement published on the U.S
infection with Salmonella can result in the organism getting into the bloodstream and producing more severe illnesses such as arterial infections (i.e.
endocarditis and arthritis," the announcement said
and others with weakened immune systems are most at risk
recent illnesses may not yet be reported as it usually takes 2 to 4 weeks to determine if a sick person is part of an outbreak," the CDC reported
A full list of recalled products may be found on the FDA's website

Nearly 100 people have fallen sick in a Salmonella outbreak involving multiple countries
92 cases of Salmonella Senftenberg have been reported
Infections have occurred in all age groups
The United States has recorded two patients
case is a 47-year-old female reported in October 2022
The second is an immunocompromised 42-year-old male with disease onset in April 2023
This person had a liver transplant in 2022
Santé publique France was informed by the national food reference laboratory that Salmonella Senftenberg had been isolated from a mixed salad containing cherry tomatoes and green leafy vegetables
it was not served as intended to airline customers
Thirteen affected countriesSick people also live in Austria
Most cases were reported between October 2022 and March 2023
according to the European Centre for Disease Prevention and Control (ECDC) and European Food Safety Authority (EFSA)
suggests suspected contaminated food entered the French market around mid-August and other countries later
Salmonella Senftenberg is a relatively uncommon serotype in cases of salmonellosis
36 and 75 cases respectively were reported to ECDC
Link to tomatoesAmong 21 patients interviewed in Austria
20 reported consumption of tomatoes and 12 said they had eaten iceberg lettuce
Tomatoes were suspected as the vehicle of infection by national authorities in France and Austria and were traced back to wholesalers in Germany
there is no microbiological evidence from tomatoes
so the source of infection has not been confirmed
Intermittent reporting of patients between August 2022 and June 2023 indicates prolonged distribution of contaminated food from a common source for about 10 months in the EU and UK
suggests a possible common source of infection or travel to Europe
Contamination of cherry tomatoes may have occurred at pre-harvest on farms during growing via different sources
“Identifying the nature and source (root cause) of microbial contamination of vegetables in the food chain remains crucial to ensure appropriate handling and activities by growers
and consumers and to prevent the risk of foodborne illness deriving from exposure to Salmonella-contaminated vegetables,” said ECDC

AXOR presents three bathroom concepts that are not merely places of function
but destinations in themselves — sanctuaries of style
According to the International Energy Agency
global energy demand could increase by 40% by 2040
power distribution and access must be improved
composed of consumers and local sustainable energy producers (using photovoltaic panels or wind turbines
for example) are among the solutions proposed
These miniature power grids are better suited to more small-scale use
Although their development and installation are making progress
they have one weakness: they are less tolerant of variations in load
To remedy the issue, Inria launched the SyNPiD project (for "self-synchronisation in power grids with periodic dynamics”)
The aim is to study these smaller and harder-to-stabilise electrical systems in detail and use mathematical modelling to optimise their operation
In collaboration with a team from the Brandenburg University of Technology Cottbus-Senftenberg (BTU) in Germany
the researcher and his colleagues have designed a methodological framework for mathematical analysis to manage frequency variations in microgrids
we know at what times of the day power consumption will be the highest
Peaks are predictable and even if there are a few variations
the network is robust enough to cope with them without causing an outage
in a village of just a few hundred inhabitants
if someone arrives and wants to charge their electric car
this causes a major variation and upsets the microgrid
This problem should be taken very seriously, because microgrids have an important role to play in the energy transition. Compared with large grids, they are better suited to using renewable energy sources, which is what everyone is looking for. In France, photovoltaic solar power currently generates 21.1 GW and wind turbines generate 23.8 GW
but still fall far short of the government's target of 101 to 113 GW of renewable energy capacity by 2028
Another advantage of microgrids is that they distribute electricity locally
which reduces transmission costs and cuts losses
not to mention the social benefits of a system that encourages local energy production
initiatives that include smaller structures
and partnerships between entities based in the same area
Microgrids are particularly recommended on islands that are currently heavily dependent on oil
where many communities have no access to electricity
They are also well suited to supplying energy to a group of buildings such as a campus
with no risk of tripping at the slightest variation
How have the SyNPiD researchers gone about improving their reliability
“The difficulty lies in modelling these small networks
delving into the details and understanding just how resilient these systems are”
the Valse project team headed up the theoretical part in terms of dynamic analysis and estimating frequency changes
while the German researchers at BTU had a suitable platform for carrying out full-scale tests
“The project lay at the crossroads of our specialities"
“We had a lot of very fruitful meetings because there was lots to discuss and many difficulties to overcome
The scientists at BTU used a platform with a total power of 110kW
Half was provided by a conventional generator
and the rest by four decentralised energy production units (equivalent to solar panels or wind turbines)
which could be compared to a small village of about 50 inhabitants
but the simulation nevertheless offered a fairly realistic order of magnitude
The teams then studied in detail how the electric current behaved in this system in order to learn from it and design an algorithm capable of measuring the whole phenomenon
“The trajectories of the current were not what we expected and were very different from what happens in a large conventional network"
The researchers identified frequency variations which
the simulation showed that these could be tolerated by the system
“These networks are more resilient than expected
sometimes all you have to do is wait and everything returns to normal after a short transition phase
You don’t necessarily have to have a shut-down each time”
The challenge now is to analyse the SyNPiD results in detail to identify with certainty when and how this type of microgrid needs to shut down
“It's very tricky because there are so many different types of behaviour"
“Our analytical framework is still under construction and all this information will feed into it”
SyNPiD project and its results are being studied by two post-docs
Further trials on other platforms are due to take place in the near future with the BTU
Will the SyNPiD methodological framework one day be used in a “real” microgrid
Denis Efimov answers in the affirmative: “We’re using power grids that were built decades ago and are still working
Our aim is to solve the problems without undoing everything

Several Jif brand peanut butter products are being recalled in Canada because of a Salmonella outbreak in the United States that has been traced to the manufacturing plant
The recalled products have been sold at retailers nationwide in Canada
according to the recall notice posted by the Canadian Food Inspection Agency
Smucker Foods of Canada Corp. is recalling the products following a recall in the United States by the J.M
The recalled products were produced in the company’s Lexington
No illnesses have been confirmed in Canada as of the posting of the recall notice today
the Centers for Disease Control and Prevention is reporting that 14 people across 12 states have been infected with the outbreak strain of Salmonella Senftenberg
There is great concern that consumers may have unused portions of the implicated peanut butter in their homes. To view photographs of the products subject to recall in Canada, click here
Consumers can use the following label information to determine whether they have the recalled peanut butter
If consumers have products matching the above description in their possession
Anyone who has eaten any of the recalled products and developed symptoms of Salmonella infection should seek medical attention
Sick people should tell their doctors about the possible exposure to Salmonella bacteria because special tests are necessary to diagnose salmonellosis
Salmonella infection symptoms can mimic other illnesses
Symptoms of Salmonella infection can include diarrhea
and fever within 12 to 72 hours after eating contaminated food
healthy adults are usually sick for four to seven days
diarrhea may be so severe that patients require hospitalization
are more likely to develop a severe illness and serious
Some people get infected without getting sick or showing any symptoms
they may still spread the infections to others
Peanut butter linked to a Salmonella outbreak in the United States has also been recalled in the United Kingdom and other countries
JDM Distributors recalled Jif Creamy Peanut Butter and Jif Extra Crunchy Peanut Butter 453-grams
The creamy version has batch code 1343006 and best before Dec
2023 while the extra crunchy type has batch code 1296425 and best before date Oct
The Food Standards Agency in the UK advised anyone who had bought the products not to eat them
they should be returned to the place of purchase for a refund
There have been no reports of related illnesses in the UK
potentially contaminated products were imported by Rainbow Asset
The firm has stopped sale and removed from shelves the affected products and initiated a voluntary recall
It affects Jif Creamy Peanut Butter with dates of Nov
2024 and Creamy Peanut Butter Portion Control Cup with dates Oct
shows peanut butter was also distributed to Canada
Smucker has recalled multiple Jif brand peanut butter types
Other firms have recalled food made with the peanut butter
Sixteen people have been infected with the outbreak strain of Salmonella Senftenberg from 12 states
Sick people range from less than one to 85 years old

The ocean economy supports 90% of global trade and provides millions of jobs. It includes shipping, tourism and offshore energy valued at US$24 trillion
sea grass and mangroves are worth US$6.9 trillion; trade and transport US$5.2 trillion; and coastline productivity and carbon absorption US$12.1 trillion
Nigeria’s establishment of a Ministry of Marine and Blue Economy is a strategic move
I believe the ministry will tap the country’s rich marine resources as an element of the national economic framework
Nigeria’s coastline stretches for 420 nautical miles and covers an exclusive economic zone of 200 nautical miles
Its maritime interests span the Gulf of Guinea
covering roughly 574,800 square nautical miles with a 2,874 nautical mile coastline
Marine resources can be exploited to create jobs and transform Nigeria into a leader in sustainable marine activities. It will help diversify the country’s oil-based economy as well. Norway is an example of how this has been done successfully
Nigeria hopes to generate over US$1.5 trillion annually from exploiting its marine resources
Create an inclusive committee for effective collaboration among stakeholders and partners. The committee should include scientists, NGOs, youth and traditional communities. Indigenous peoples, persons with disabilities, and the relevant federal government agencies should not be left out
The committee should advance beyond the scope of the Expanded Committee on Sustainable Blue Economy in Nigeria inaugurated by the former president Muhammadu Buhari
Integrate sustainability into policies and strategies
Policies should prioritise sustainable marine resource use
Strategies should focus on sustainable and ethical harvesting
unemployed youths and women should be trained
Improved programmes would foster sustainable practices and raise the sector’s contribution to the country’s gross domestic product
Sustain investment in ports, transport systems and storage facilities. The same should apply to research and technology. Aquaculture, offshore energy and marine biotechnology should be advanced to increase efficiency and sustainability. Additionally, remote coastal communities should have access to resilient and blue renewable energy sources and systems to enhance protection of coastal and ocean resources
Oil is a key revenue source for the country. But it has led to major environmental problems. Harnessing the blue economy could be a game changer for Nigeria.
First, it could create jobs and generate income from fisheries, aquaculture, tourism, shipping and renewable energy.
Second, a blue economy could mitigate environmental damage as it enables the restoration of marine ecosystems. Unlike oil, fisheries are renewable. Nigeria’s oil-rich Niger Delta has experienced severe environmental harm. A shift to greener energy supplies could make a massive difference.
Third, it creates the opportunity to grow the tourism sector. Seychelles and Mauritius are examples of countries that earn foreign exchange from marine exports and tourism.
Fourth, it could help attract investment to Nigeria’s marine infrastructure, fisheries and technology.
Fifth, it could help decrease regional and social inequalities in coastal communities.
Finally, investment in the blue economy could encourage marine biology, oceanography and marine technology research. This could, in turn, lead to global innovations.
Despite competition from more experienced countries in the marine industry, the blue economy offers Nigeria significant potential. Strategic planning, global partnerships and investment can make it a reality.

but this kind of vacation is especially popular since 2020
Many Germans love travelling with their tent or in a camper van
but the camping boom has reached unimagined heights in times of corona crisis
According to the Caravanning Industry Association (CIVD)
54,439 camper vans and caravans were registered in Germany during the first half of 2020; that is as many as in the whole of 2016
Almost no other kind of vacation can be as corona-safe – as a result of the distance between visitors on the camping site
staying in the open air and living in your own home
But what does a camping vacation involve in these times of crisis
It is mainly the spontaneity of camping that makes it an adventure
but this year camping is impossible without a reservation
Site operators can only use 50 to 70% of their pitches because of the pandemic
tourists can look forward to relaxed stays with little bustle and lots of open space between themselves and neighbouring campers
but of course campers also have to observe the rules
If you simply pitch your tent in a German forest
you risk receiving a fine of up to 500 euros or even more if you do so with a camper van
Nevertheless, camping enthusiasts do not have to forego interesting camping locations in Germany. Adventurers will find temporary camping sites on the Pop-Up Camps website: for example
on Lüneburg Heath or the Ferropolis peninsular
an open-air museum with gigantic opencast mining equipment
