State and local public health officials interviewed people about the foods they ate in the week before they got sick. Of the 16 people interviewed, 10 (63%) reported eating ground beef. Nine sick people reported purchasing the ground beef from ShopRite locations in Connecticut, New Jersey, and New York. Seven of these people specifically reported purchasing 80% lean ground beef products. Two people reported purchasing ground beef products from ShopRite but could not remember the type of ground beef. Epidemiologic showed that ground beef was the likely source of the outbreak.
Whole genome sequencing (WGS) showed that bacteria from sick people’s samples were closely related genetically. This suggested that people in this outbreak may have gotten sick from the same food.

A Salmonella outbreak in a Welsh city has been declared over after sickening more than 30 people.
A total of 33 confirmed and one probable case were linked to a pub in Wrexham.
Despite an investigation and testing, the precise source or route of transmission in the Salmonella Infantis outbreak was not identified.
In late July, an Outbreak Control Team (OCT) was established including Public Health Wales, Betsi Cadwaladr University Health Board and Wrexham County Borough Council’s environmental health team.
No details on the age range or gender of patients were released to protect their identity.

Cases where people have contracted listeria infection are investigated by the Public Health Authority in collaboration with the regional infection control units and the Swedish Food Agency. The outbreak of listeria can be linked to salmon products from one producer.
A total of 19 people have been reported sick in the outbreak with the same variant of listeria serotype IIa ST37 since autumn 2022, of which 15 cases since the end of May this year (see figure). The cases are aged 63-93, of which 13 are men and six are women. The cases have been reported from 10 different regions. Six of the disease cases have died in close connection with their listeria infection. However, it is often difficult to say what role the listeria infection has as a cause of death because most of the patients affected have severe underlying diseases.
Of the cases for which there is information about what they ate before becoming ill, 14 cases have eaten some type of vacuum-packed salmon (digging/cold-smoked/hot-smoked salmon) from one of two different brands. Both of these brands are produced by the same company and listeria has been detected in both products and environmental samples in the company’s facility. Comparisons of the bacteria’s genetic material in samples from food, plants and human cases show that it is the same variant of listeria, which points to the salmon products being the likely source of infection. The company has increased its sampling and is carrying out further clean-up measures at the facility.
The outbreak is being investigated together with the infection control units and the Swedish Food Agency.

FDA’s investigation is ongoing. Products may be added to this advisory. Additional recall information is available below.
Illness can occur within a few hours or as long as two to three days after eating contaminated food. More severe forms of listeriosis may take anywhere from three days to three months to develop. Mild symptoms may include a fever, muscle aches, nausea, vomiting, and diarrhea. If the more severe form of listeriosis develops, symptoms may include headache, stiff neck, confusion, loss of balance, and convulsions.

Patulin is a harmful mycotoxin produced by fungi typically found in damaged fruits, including apples, pears, and grapes. In a recent breakthrough, researchers identified a new filamentous fungal strain that can degrade patulin by transforming it into less toxic substances. Their findings provide important insights into the degradation mechanisms for patulin found in nature, and can lead to new ways of controlling patulin toxicity in our food supplies.

During 2006–2021, Canada had 55 laboratory-confirmed outbreaks of foodborne botulism, involving 67 cases. The mean annual incidence was 0.01 case/100,000 population. Foodborne botulism in Indigenous communities accounted for 46% of all cases, which is down from 85% of all cases during 1990–2005. Among all cases, 52% were caused by botulinum neurotoxin type E, but types A (24%), B (16%), F (3%), and AB (1%) also occurred; 3% were caused by undetermined serotypes. Four outbreaks resulted from commercial products, including a 2006 international outbreak caused by carrot juice. Hospital data indicated that 78% of patients were transferred to special care units and 70% required mechanical ventilation; 7 deaths were reported. Botulinum neurotoxin type A was associated with much longer hospital stays and more time spent in special care than types B or E. Foodborne botulism often is misdiagnosed. Increased clinician awareness can improve diagnosis, which can aid epidemiologic investigations and patient treatment.
