Main points

A total of 402 confirmed cases of Shiga toxin-producing Escherichia coli (STEC) O157 were reported in England and Wales in 2020.

The lowest incidence of STEC O157 was in the London region (0.29 per 100,000 population) and the highest in the South West region (1.04 per 100,000 population).

Children aged 5 to 9 years had the highest incidence of infection (1.50 per 100,000 population, 95% confidence interval (CI) 1.12 to 1.96).

One-third of confirmed STEC O157 cases in England were hospitalised and 3% were reported to have developed Haemolytic Uraemic Syndrome (HUS).

A further 286 specimens in England and 41 in Wales were positive for Shiga toxins (Stx) genes on polymerase chain reaction (PCR) at the Gastrointestinal Bacteria Reference Unit (GBRU) but an organism was not cultured.

The most commonly isolated non-O157 STEC serogroup was STEC O26 (England: n=103 out of 553, 19%; and Wales: n=26 out of 268, 15%).

Three outbreaks of STEC involving 63 cases in England were investigated in 2020.

UK – British Lion unveils new code of practice for eggs

Posted on June 30, 2023 by | Leave a comment

The Grocer

A new enhanced version of the British Lion Code of Practice has been launched to mark the scheme’s 25th anniversary.

Version eight of the Lion Code incorporated the latest scientific veterinary advice and industry knowledge to ensure British Lion Eggs can continue to be produced to the highest standards of food safety, the industry body said.

The code of practice covers more than 700 auditable points from salmonella vaccination to complete traceability of hens, eggs, and feed.

It has also included enhanced sampling and testing, auditing and enforcement and updates to rodent control, on-farm protocols plus improvements to its animal welfare criteria.

The code is independently audited and the most comprehensive egg safety standard in the world. It is the UK’s most successful food safety scheme, said the British Egg Industry Council.

“The introduction of the Lion Code in 1998 effectively eliminated Salmonella and restored consumer confidence in British eggs,” said Mark Williams, BEIC chief executive.

USA – Preliminary Incidence and Trends of Infections Caused by Pathogens Transmitted Commonly Through Food — Foodborne Diseases Active Surveillance Network, 10 U.S. Sites, 2022

Posted on June 30, 2023 by | Leave a comment

CDC

The figure is a photo of a worker in a produce section with information about foodborne illnesses.

Summary

What is already known about this topic?

Campylobacter and Salmonella are the leading causes of bacterial enteric infections transmitted commonly by food. Reported incidence of enteric infections was lower during the COVID-19 pandemic (2020–2021) compared with previous years.

What is added by this report?

During 2022, FoodNet identified higher incidences of Shiga toxin-producing Escherichia coli, Yersinia, Vibrio, and Cyclospora infections compared with 2016–2018. Campylobacter, Salmonella, Shigella, and Listeria incidences did not change.

What are the implications for public health practice?

Progress in reducing enteric infection incidence was not observed during 2022, as influences of the COVID-19 pandemic subsided. Collaboration among food growers, processors, retail stores, restaurants, and regulators is needed to reduce pathogen contamination during poultry slaughter and to prevent contamination of leafy greens.

USA – Cronobacter infections in babies are now a reportable disease

Posted on June 30, 2023 by | Leave a comment

Food Safety News

The CDC has announced it will begin tracking infections caused by cronobacter, which was behind an outbreak in 2021-22 among babies and caused an infant formula shortage that plagued the nation for months.

The council is the body that recommends what diseases are “reportable.” That list already includes illnesses from other foodborne pathogens, including E. coli, Salmonella, and Listeria. About 120 other illnesses are on the list of “nationally notifiable” pathogens. The council and the CDC manage the list.

When the recommendation becomes active, cronobacter infections identified in infants less than 1-year-old will be reported by doctors and laboratories to state health departments. Those departments will then notify the CDC.

USA – Sandwiches recalled because product was made with uncooked chicken

Posted on June 30, 2023 by | Leave a comment

Food Safety News

Compass USA, of Charlotte, NC, is recalling over 2,000 Fresh To You Chicken Filet Sandwiches because the chicken sandwich was made with uncooked chicken.

According to the Centers for Disease Control and Prevention (CDC), raw chicken is often contaminated with Campylobacter bacteria and sometimes with Salmonella and Clostridium perfringens bacteria, all of which can lead to serious food poisoning.

According to the details posted online by the FDA, the recall was initiated on June 8, 2023, and is ongoing.

Salmonella outbreak ongoing with 130 sick; Listeria incident over in UK

Posted on June 30, 2023 by | Leave a comment

Food Safety News

Investigations into a Salmonella outbreak are ongoing but a Listeria outbreak has ended, according to the Food Standards Agency (FSA).

More than 130 people are sick with Salmonella Mbandaka after eating chicken products from Ukraine. Four patients were admitted to hospitals and one person died.

In response to repeated non-compliance with partly cooked chicken products from Ukraine, a system of Intensified Official Controls (IOC) was started in April. This included a requirement that the next 10 imported consignments from the implicated establishment would be subject to extra inspections.

Because of continued breaches of food safety requirements, this was escalated to Imposed Checks in May. These physical, documentary and testing inspections will remain in place until a minimum of 30 consecutive favorable results are achieved.

The UK importer has stopped receipt of the steam-cooked chicken product until the issue is resolved and is testing all their uncooked product on arrival into the UK for Salmonella. An investigation by Ukrainian authorities has resulted in risk management measures being taken at the facilities of the manufacturer.

In late 2022, the European Centre for Disease Prevention and Control (ECDC) reported that Finland had 89 cases while a few patients also lived in the Czech Republic, Estonia, France, Germany, Ireland, the Netherlands, and Israel.

Shocking Increase in Norovirus Outbreaks on Cruise Ships – Vacationers Beware!

Posted on June 30, 2023 by | Leave a comment

Alpha Beta Stock

As vacation-starved Americans return to cruise ships in record numbers, the surge in popularity has led to an increase in norovirus incidents on board. With occupancy rates at around 100% capacity, cruise lines like Royal Caribbean Group have reported a significant rebound in the first quarter of 2023. However, this resurgence has come with a downside, as 13 outbreaks of the highly contagious norovirus, also known as the ‘cruise ship virus,’ have been reported this year alone, marking the highest number since 2012 and emphasizing the potential health risks associated with large numbers of passengers on board.

Research – Does Vegan Cheese Pose a Food Safety Risk?

Posted on June 30, 2023 by | Leave a comment

Food Poisoning Bulletin

Recently, the Centers for Disease Control and Prevention (CDC) published an analysis of a Salmonella outbreak linked to vegan cheese made from cashews. The 2021 outbreak linked to Jule’s cashew brie marked the second time since 2014 that illnesses in multiple states were linked to cashew cheese.

Does vegan cheese pose a food safety risk? If it’s made from nuts, it might.

Cashews and Kill Steps

The CDC’s 2021 report on the Jule’s brie Salmonella outbreak states that whole genome sequencing tests on the Salmonella strain cultured from patients produced the same genetic “fingerprint,” meaning the patients were exposed to the same source of contaminated food. Investigators found this outbreak strain in samples of Jule’s cheese, in the facility where it was made, and in the specific lot of raw cashews used to make the cheese.

The CDC’s recent analysis of the outbreak states that U.S. Food and Drug Administration (FDA) investigators identified cashews as the ingredient that was the likely source of contamination and noted that no lethality treatment, or “kill step” such as pasteurization or irradiation was performed before cashew processing.

Similarly, a kill step was also omitted in the manufacture of The Cultured Kitchen cashew cheese linked to the 2014 Salmonella outbreak. Tests performed during that investigation revealed the presence of the outbreak strain in samples of the cheese collected from a patient’s home and in a batch of fermenting, raw, cashews collected from the facility where the product was made.
