Irish Mirror

A dad who claims he hasn’t stopped farting since eating a ham sandwich five years ago is suing a food stall for €235,000.

He claims to have been bedridden for five weeks with salmonella as a result of eating the item.

The lawyers added that Mr Prades has had regular and uncontrollable flatulence ever since, embarrassing him in public and waking him up at night.

Research – From chicken to salad: Cooking salt as a potential vehicle of Salmonella spp. and Listeria monocytogenes cross-contamination

PubMed

Epidemiological studies show that improper food handling practices at home account for a significant portion of foodborne illness cases. Mishandling of raw meat during meal preparation is one of the most frequent hazardous behaviours reported in observational research studies that potentially contributes to illness occurrence, particularly through the transfer of microbial pathogens from the raw meat to ready-to-eat (RTE) foods. This study evaluated the transfer of two major foodborne pathogens, Salmonella enterica and Listeria monocytogenes, from artificially contaminated chicken meat to lettuce via cooking salt (used for seasoning) during simulated domestic handling practices. Pieces of chicken breast fillets were spiked with five different loads (from ca. 1 to 5 Log CFU/g) of a multi-strain cocktail of either S. enterica or L. monocytogenes. Hands of volunteers (gloved) contaminated by handling the chicken, stirred the cooking salt that was further used to season lettuce leaves. A total of 15 events of cross-contamination (three volunteers and five bacterial loads) were tested for each pathogen. Immediately after the events, S. enterica was isolated from all the cooking salt samples (n = 15) and from 12 samples of seasoned lettuce; whereas L. monocytogenes was isolated from 13 salt samples and from all the seasoned lettuce samples (n = 15). In addition, S. enterica and L. monocytogenes were able to survive in artificially contaminated salt (with a water activity of 0.49) for, at least, 146 days and 126 days, respectively. The ability of these foodborne pathogens to survive for a long time in cooking salt, make it a good vehicle for transmission and cross-contamination if consumers do not adopt good hygiene practices when preparing meals.

Research – Public Health Risk of Foodborne Pathogens in Edible African Land Snails, Cameroon

CDC

In tropical countries, land snails are an important food source; however, foodborne disease risks are poorly quantified. We detected Campylobacter spp., Yersinia spp., Listeria spp., Salmonella spp., or Shiga-toxigenic Escherichia coli in 57%–86% of snails in Cameroon. Snail meat is a likely vector for enteric diseases in sub-Saharan Africa countries.

Research – A 3-year multi-food study of the presence and persistence of Listeria monocytogenes in 54 small food businesses in Ireland

Academia Edu

The problem of assessing the occurrence of the food-borne pathogen Listeria monocytogenes in the food chain, and therefore the risk of exposure of the human population, is often challenging because of the limited scope of some studies.

In this study the occurrence of L. monocytogenes in food from four major food groups, dairy products,
meats, seafood and vegetables, and associated food processing environments in Ireland was studied over a three-year period. Fifty-four small food businesses participated in the study and sent both food and environmental samples every 2 months between 2013 and 2015. L.monocytogenes was isolated using the ISO11290 standard method.

Confirmation of L. monocytogenes and identification of serogroups were achieved using a multiplex PCR
assay, and for some isolates serotype was determined using commercial antisera. Pulsed- field gel electrophoresis (PFGE) analysis was performed on all isolates allowing the relatedness of isolates from different food businesses
to be compared nationwide. In total, 86 distinct pulsotypes were identified. The overall occurrence of L.
monocytogenes in food samples was 4.2%, while in environmental samples it was 3.8%. In general, the occurrence of L. monocytogenes in food businesses decreased over the course of the study, presumably reflecting increased awareness and vigilance.

The majority of the pulsotypes detected were unique to a particular food group (63/
86), while only three pulsotypes were found in all four food groups investigated. The highest occurrence in food was found in the meat category (7.5%) while seafood had the lowest rate of occurrence (1.8%). Seventeen of the pulsotypes detected in the study were persistent, where persistence was defined as repeated isolation from a single facility with a minimum time interval of 6 months. Using PFGE, 11 of the pulsotypes identified in this study were indistinguishable from those of 11 clinical isolates obtained from patients in Ireland over the last 4 years, highlighting the fact that these pulsotypes are capable of causing disease.

Overall, the study shows the diversity of L. monocytogenes strains in the Irish food chain and highlights the ability of many of these strains to persist in food processing environments. The finding that a significant proportion of these pulsotypes are also found in clinical settings highlights the need for continued vigilance by food producers, including frequent sampling and typing of isolates detected.

Research – Listeria: What you need to know

Medical News Today

Listeriosis is a food-borne infection caused by Listeria bacteria. The majority of people who become infected might barely notice the illness. However, those at risk can be severely affected, and mortality rates are relatively high.

Listeriosis, also called Listeria, can be a serious infection; it strikes pregnant women, newborns, the elderly, and anyone with a weakened immune system.

In this article, we will look at the symptoms, diagnosis, and treatment of listeriosis. We will also discuss how the bacteria works, the best ways to avoid infection, and recent research into preventing the disease.

Fast facts on listeriosis

  • Listeriosis is an infection caused by Listeria monocytogenes
  • An estimated 260 Americans die of listeriosis yearly.
  • Only immunosuppressed individuals and pregnant women are at risk of a serious case of listeriosis.
  • Listeriosis can lead to septicemia or meningitis.
  • Pregnant women are 10 times more likely to be infected with Listeria than the general population.

China – Research – Vital Surveillances: Epidemiological Analysis of Foodborne Botulism Outbreaks — China, 2004–2020

China CDC

kswfoodworld

Abstract

IntroductionFoodborne botulism is a rare, potentially fatal illness resulting from the ingestion of foods contaminated with preformed botulinum neurotoxin types A, B, E, or F, produced by Clostridium botulinum. The descriptive epidemiology of foodborne botulism outbreaks in China during 2004−2020 was performed to inform public health response strategies.

Results

During 2004−2020, a total of 80 foodborne botulism outbreaks occurred in China, involving 386 illnesses and 55 deaths; most outbreaks were reported between June and August, with a sharp peak in January; 22 out of 31 PLADs reported foodborne botulism outbreaks, Xinjiang reported the largest number of outbreaks (20), followed by Qinghai (13); the most commonly implicated food was home-prepared traditional processed stinky tofu and dried beef, accounting for 51.25% events. Improper processing and improper storage in contributing factors accounted for 77.50% outbreaks. Initial misdiagnosis occurred in 27.50% of cases.

Conclusions

Outbreaks of foodborne botulism had a high case-fatality rate. Targeted food safety and popularization education to farmers and herdsmen in Xinjiang and Qinghai related to botulism prevention should be carried out, and timely outbreak investigation and hospital surge capacity should be improved.

WARNING LETTER
CMS Case # 61934

January 28, 2022

Dear Ms. Williamson:

The United States Food and Drug Administration (FDA) conducted an inspection of your ready-to-eat (RTE) cheese manufacturing facility located at, 938 E 5th Street, Claremore, Oklahoma, from July 26, 2021 through July 30, 2021. In addition to manufacturing RTE cheese products, you also produce unpasteurized and pasteurized milk. Our inspection was initiated after Oklahoma Department of Agriculture, Food and Forestry (ODAFF) was notified of a report from Missouri Department of Health and Senior Services (MDHSS) which documented that an individual was hospitalized with listeriosis after purchasing and consuming raw cow’s milk from your firm. Subsequently, you conducted a voluntary recall of your unpasteurized milk and cheese products.

During our inspection of your facility, FDA investigators found serious violations of the Current Good Manufacturing Practice, Hazard Analysis, and Risk-Based Preventive Controls for Human Food regulation (CGMP & PC rule), Title 21, Code of Federal Regulations, Part 117 (21 CFR Part 117). During this inspection, FDA collected environmental samples (i.e., swabs) from various areas in your processing facility. FDA laboratory analysis of the environmental swabs found the presence of L. monocytogenes, a human pathogen, in your facility. At the conclusion of the inspection, the FDA investigators issued your facility a Form FDA 483 (FDA-483), Inspectional Observations.

Based on FDA’s inspectional findings, we have determined that your RTE cheese products manufactured in your facility are adulterated within the meaning of section 402(a)(4) of the Federal Food, Drug, and Cosmetic Act (the Act) [21 U.S.C. § 342(a)(4)], in that they were prepared, packed or held under insanitary conditions whereby they may have been contaminated with filth or rendered injurious to health. You can find the Act and FDA regulations through links on the FDA’s home page at http://www.fda.gov.External Link Disclaimer

On August 6, 2021, you submitted a Qualified Facility Attestation for Human Food Facility. Additionally, we received your written responses on August 20, 2021, August 24, 2021, and September 11, 2021, which describe your completed and planned corrective actions. After reviewing the inspectional findings and responses you provided, we are issuing this letter to advise you of FDA’s concerns and provide detailed information describing the findings at your facility.
