USA – Food Poisoning at Central Connecticut State University

Food Poison Journal

Press reports that Central Connecticut State University officials are investigating a possible food poisoning at one of its campus dining facilities.

Officials said the university Environmental Health & Safety Department is working with the  New Britain Department of Public Health and food service provider Sodexo to investigate potential food poisoning at The Hilltop Café.

The cafe is temporarily closed while health officials try to isolate the potential cause. The other cafeterias are open. The cafe is in the eastern part of the campus, between the football field and the recreation center.

UK dealing with E. coli and Salmonella outbreaks

Food Safety News

The United Kingdom is dealing with a serious outbreak of E. coli and several strains of Salmonella Enteritidis, according to the Food Standards Agency (FSA).

One more case has been added to the ongoing Shiga toxin-producing E. coli (STEC) O183 outbreak, bringing the total to 25 sick since May.

One person has died; while most patients live in England, others are sick in Northern Ireland, Scotland, and Wales.

FSA and the UK Health Security Agency (UKHSA) are trying to find the source with help from other public health agencies. Several product supply chains have been investigated, but no vehicle of infection has yet been identified.

FSA is also investigating outbreaks of separate strains of Salmonella Enteritidis linked to Polish eggs and poultry products.

One outbreak is behind 47 confirmed cases, of which 25 were linked to a restaurant and another 18 ill people had probable restaurant exposure.

Polish authorities found Salmonella Enteriditis at one site that sent eggs to the UK. Eggs from this source have also been linked to a second UK restaurant associated with the outbreak.

USA- Inspection Report released on Carniceria Guanajuato after 55 sickened with Salmonella

Food Poison Journal

The Chicago Department of Public Health (CDPH) and the Illinois Department of Public Health (IDPH) are investigating an outbreak of Salmonella, a bacteria that is a common cause of food poisoning. As of September 22, 2023, CDPH has identified 55 individuals with Salmonella infections who ate prepared food from a taqueria in Carniceria Guanajuato located at 3140 N California in Chicago. Of these, 10 people have been hospitalized. Carniceria Guanajuato voluntarily closed the taqueria on September 8, 2023 and is cooperating with CDPH to determine a source of the infections. If you have purchased prepared food from the taqueria or the prepared food section of the grocery store since August 29, 2023, discard it and do not eat it. If you ate food purchased from the prepared food section (taqueria or prepared foods in the grocery section) since August 29, 2023, you may have been exposed to Salmonella.

USA – Nine with E. coli at Huntley High – source still a mystery – Inspection Reports released

Food Poison Journal

The McHenry County Department of Health (MCDH) and Huntley Community School District 158 are working collaboratively to respond to a recent outbreak of Shiga Toxin-Producing E. coli (STEC) at Huntley High School. There are now currently nine confirmed cases of STEC, all of which involve students. The first case was identified on Sunday, September 17. At this time, there is insufficient evidence to indicate the source of the illness. The MCDH is actively monitoring for potential cases; there are no other known McHenry County STEC cases outside of this outbreak.

In a letter to parents, students, and staff, Huntley Community School District 158 officials reiterated that the situation is being taken seriously and that the safety and well-being of students and staff is of the utmost importance.

Research -Two successive outbreaks of acute gastroenteritis due to Norovirus GII.6 in a holiday camp house

When two outbreaks occur in the same institution within a short period of time, an important health and social concern is generated. Two gastroenteritis outbreaks occurring a week apart in the same facility were reported in Lleida, Spain, in 2018. The objective of this study was to describe the clinical, epidemiological and microbiological investigation carried out and to determine the risk factors. Demographic data, food consumption and symptoms were collected. Health inspections of the facility were carried out. Risk ratio and their 95% confidence intervals were estimated for the implication of each food consumed. The attack rate was 89.7% in the first outbreak and 69.6% in the second outbreak. The most frequent symptoms in the first and second outbreak were abdominal pain (88.5% and 100%, respectively), vomiting (80.8% and 87.5%, respectively) and nausea (69.2% and 81.3%, respectively). The first outbreak was associated with the consumption of a salad and the second with a cheese omelet. Norovirus GII.6 was detected by RT-PCR and sequenced in both groups of students and in the food handlers who prepared the meals. These results highlight the importance of exclusion from work of food handlers with gastroenteritis, the adequate availability of mechanisms for correct hand washing and the correct cleaning of surfaces.

Research – Study shows outbreaks increasing in Switzerland

Food Safety News

Researchers have highlighted increased foodborne outbreaks in Switzerland in the past 15 years.

Foodborne outbreaks in the country are identified by cantonal authorities and reported to the Federal Food Safety and Veterinary Office (FSVO). Between 2007 and 2021, 200 outbreaks were recorded. The highest amount during the study period was in 2021, and the lowest was in 2012.

At least 4,668 people fell ill, 303 were hospitalized, and 18 died. The top pathogens detected were Salmonella, Campylobacter, norovirus, and coagulase-positive staphylococci. Other incidents were caused by Scombroid poisoning, Bacillus, Listeria, and Clostridium perfringens.

Outbreaks took place in restaurants, canteens and catering sites, private households, kindergartens and schools, and takeaway establishments, according to the study published in the Journal of Consumer Protection and Food Safety.

Food items reported concerning outbreaks included mixed products (such as composite meals), fish and fish products, milk and milk products, and meat and meat products.

Research – Detection and Control of Foodborne Pathogens

MDPI

The globalization of food trade and the emergence of disease outbreaks involving several foodborne pathogens and foods has focused the attention of both the research community and consumers on food safety. Microbial contamination can involve different stages of food processing and distribution, with a potentially dramatic impact on human health and food business. Several methods, involving culture-dependent and -independent techniques, were developed to detect foodborne pathogens in the food supply chain. In this respect, gold-standard reference methods are currently available for most pathogens, but some of them are time-consuming and expensive. Moreover, routine controls carried out by manufacturers and food safety authorities are normally focused on bacteria and not on viruses and fungi, which can have a significant impact on food safety. In the European Union, the number of human cases caused by Noroviruses and other Caliciviruses increased sharply in 2021 [1]. Therefore, based on the evidence given by an increasing amount of research, control strategies show a clear trend towards molecular techniques, such as polymerase chain reaction (PCR), multiplex PCR, real-time PCR (qPCR), reverse transcriptase PCR (RT-PCR), DNA microarrays, nucleic acid sequence-based amplification (NASBA), isothermal DNA amplification techniques, and next-generation sequencing (NGS) [2]. Moreover, to expand the knowledge on the behaviour of pathogens in food environments, proteome profiling and biosensors shed light on how these microorganisms interact and prevail in food systems [3].

Viet Nam – Salmonella poisons Hoi An banh mi shop

VN Express

Salmonella bacterial contamination gave 313 people food poisoning after eating food from a banh mi eatery in Hoi An Town, the Quang Nam health department announced Saturday.

Mai Van Muoi, director of the Quang Nam Department of Health, said the food poisoning came from the char siu (BBQ pork) and the various herbs and vegetables in banh mi samples taken from Ms. Phuong, a famous eatery in Hoi An. The results came from the analysis of food samples and fecal samples of patients at the Nha Trang Pasteur Institute.

The department said a total of 3,600 people bought banh mi from the eatery on September 11 and September 12. Later, 313 of said customers suffered the symptoms of food poisoning. The number included 103 foreigners. And 273 people had to be hospitalized, all of whom have since been discharged. There were no deaths associated with the incident.
