USA -Outbreak Investigation of E. coli O157:H7: Raw Cheddar Cheese (February 2024)

FDA

Current Update

February 28, 2024

The FDA and CDC, in collaboration with state and local partners, are continuing to investigate a multistate outbreak of E. coli O157:H7.

As this investigation is ongoing, FDA and CDC continue to recommend that people do not eat, sell, or serve RAW FARM-brand Raw Cheddar cheese made by RAW FARM, LLC, of Fresno, CA. State and local public health officials have interviewed people about the foods they ate in the week before they became sick. Nearly all sick people, seven out of nine (78%), reported eating RAW FARM-brand Raw Cheddar cheese and this continues to show these cheeses are the likely source of this outbreak. E. coli can cause an infection that may lead to serious kidney problems. Anyone who ate the raw cheeses and has symptoms of E. coli infection should contact their healthcare provider.

As of February 28, 2024, a total of 11 confirmed infections have been reported from five states, including CA (4), CO (3), NJ (1), TX (1), and UT (2). Whole genome sequencing analysis of E. coli isolates from ill people shows that they are all closely related genetically to each other. This means that people in this outbreak are likely to share a common source of infection. Five patients have been hospitalized; two developed hemolytic uremic syndrome (HUS), a serious condition that can lead to kidney failure. No deaths have been reported.

Health officials in CO, CA, and UT have collected various RAW FARM-brand products for testing, including Raw Milk, Raw Butter, Raw Cheddar cheese, and Raw Kefir. So far, no product samples have detected E. coli. While E. coli has not been found in product samples, epidemiologic evidence shows that RAW FARM-brand Raw Cheddar cheese made by RAW FARM, LLC is the likely source of this outbreak. Additional testing is ongoing.

In response to this investigation, on February 16, 2024, RAW FARM, LLC initiated a recall of certain lots of RAW FARM-brand Raw Cheddar cheese currently within shelf life. On February 26, 2024, RAW FARM, LLC withdrew their voluntary recall.

The investigation is ongoing, and FDA will update this advisory should additional consumer safety information become available.

Research – Finland – Risk assessment of STEC in medium-cooked ground beef patties

Ruokavirasto

Abstract
Medium-rare or medium-done ground beef patties are associated with the risk of
microbiological contamination, especially from Shiga toxin-producing Escherichia coli
(STEC) bacteria, which can cause gastrointestinal infections. The objective of this risk
assessment was to evaluate the food poisoning risk associated with medium-done
ground beef patties made from Finnish beef and served in foodservice establishments.
Simultaneously, the Finnish Food Authority’s recommendation for preparing medium
ground beef patties was assessed. The recommendation includes, among other things, the
removal of surfaces from the meat before grinding it into ground beef in the kitchen of food
service establishments.
The risk assessment used an application based on a Bayesian statistical model. The data
included information collected from the Finnish Food Authority’s registers and a survey
conducted as part of the project for foodservice establishments. To evaluate the Finnish
Food Authority’s recommendation, a study was conducted to determine how STEC bacteria
are transferred from the surface of experimentally contaminated roast beef to the inner
parts of the meat when the surfaces are removed.
The risk of the population getting sick was greatly influenced by the proportion of ground
beef patties served medium and how hot the patties were heated. In a situation where
approximately a tenth of the patties were cooked medium (internal temperature 55°C),
there would be 100 illnesses per 100,000 residents in Finland per year. Surface removal as a
risk management measure only worked in those experiments with roasts when the level of
contamination was low. Even then, some of the tested roasts still had STEC bacteria.

Research- Effect of gas ultrafine bubbles on the potency of antimicrobials against Escherichia coli O157:H7 biofilms on various food processing surfaces

Wiley Online

Abstract

This study investigated the impact of incorporating gas [air, carbon dioxide (CO2), and nitrogen (N2)] UFB on the potency of chlorine (Cl2; 50, 100, and 200 ppm) and peracetic acid (PAA; 20, 40, and 80 ppm) antimicrobial (AM) solutions against fresh (3 days) and aged (30 days) E. coli O157:H7 biofilms on polypropylene, silicone, and stainless-steel surfaces. The biofilms were statically grown on polypropylene, silicone, and stainless-steel coupons (7.62 × 2.54 cm) at 25°C for 3 or 30 days by immersing in a 3-strain cocktail of E. coli. The incorporation of air, CO2, and N2 UFB in AM solutions resulted in significantly increased log reductions (2.1–3.7 logs) in fresh and aged E. coli biofilms on all surfaces compared to solutions without UFB, except for N2 UFB on aged stainless-steel biofilms and air UFB on aged polypropylene biofilms, which resulted in similar log reductions as solutions without UFB (1.5–2.1 logs).

11 sick in French cheese STEC O26 E. coli outbreak

Food Safety News

The number of children sick in a severe E. coli outbreak in France linked to raw milk cheese has risen to 11.

The 11 hemolytic uremic syndrome (HUS) cases were reported in late 2023. HUS is a severe complication associated with E. coli infections that causes kidney failure. Santé publique France surveillance on HUS only covers children younger than 15 years old in the country, so there could be other sick people in the outbreak.

Five young children attending the Minimes crèche in Toulouse had to be hospitalized in November. Stool cultures revealed Shiga toxin-producing E. coli (STEC) infection. Cheese has tested positive for E. coli O26.

The other six children with HUS infected with the outbreak strain are unrelated to the crèche and live in different regions.

Speaking to different French media outlets, the parents of two girls, Élise, aged 7, and Clara, 18 months old, revealed how their children had been affected and their ongoing health issues
