Research -Shiga Toxin–Producing Escherichia coli O157:H7 Illness Outbreak Associated with Untreated, Pressurized, Municipal Irrigation Water — Utah, 2023

CDC

During July–September 2023, an outbreak of Shiga toxin–producing Escherichia coli O157:H7 illness among children in city A, Utah, caused 13 confirmed illnesses; seven patients were hospitalized, including two with hemolytic uremic syndrome. Local, state, and federal public health partners investigating the outbreak linked the illnesses to untreated, pressurized, municipal irrigation water (UPMIW) exposure in city A; 12 of 13 ill children reported playing in or drinking UPMIW. Clinical isolates were genetically highly related to one another and to environmental isolates from multiple locations within city A’s UPMIW system. Microbial source tracking, a method to indicate possible contamination sources, identified birds and ruminants as potential sources of fecal contamination of UPMIW. Public health and city A officials issued multiple press releases regarding the outbreak reminding residents that UPMIW is not intended for drinking or recreation. Public education and UPMIW management and operations interventions, including assessing and mitigating potential contamination sources, covering UPMIW sources and reservoirs, indicating UPMIW lines and spigots with a designated color, and providing conspicuous signage to communicate risk and intended use might help prevent future UPMIW-associated illnesses.

USA – Cracker Barrel in Bourbonnais Illinois linked to Salmonella Outbreak

Food Poison Journal

The Kankakee County Health Department (KCHD) and Illinois Department of Public Health (IDPH) are investigating an outbreak of Salmonella, a bacteria that is a common cause of food poisoning. As of May 14th1, 2024, KCHD has identified 8 individuals with Salmonella infections who ate prepared food from Cracker Barrel located on 50 Ken Hayes Dr in Bourbonnais.

Cracker Barrel voluntarily closed on May 4th, 2024 and is cooperating with KCHD to determine a source of the infections. KCHD performed an environmental assessment of Cracker Barrel and provided guidance on safe food handling practices and environmental cleaning to prevent further spread of disease.

Research – Foodborne Disease Outbreaks Linked to Foods Eligible for Irradiation, United States, 2009–2020

CDC

Food irradiation can reduce foodborne illnesses but is rarely used in the United States. We determined whether outbreaks related to CampylobacterSalmonellaEscherichia coli, and Listeria monocytogenes were linked to irradiation-eligible foods. Of 482 outbreaks, 155 (32.2%) were linked to an irradiation-eligible food, none of which were known to be irradiated.

Saudi Arabia – Botulism outbreak traced to mayonnaise at Riyadh restaurant

Arab News

RIYADH: The Ministry of Municipal, Rural Affairs and Housing announced on Saturday that a Saudi Food and Drug Authority laboratory test had found clostridium botulinum in a Bon Tum mayonnaise brand used by the Hamburgini food chain.

Since the bacterium was discovered in a Bon Tum factory, the ministry has collaborated with the SFDA and other authorities to enforce additional measures beyond those previously implemented.

These measures include suspending the distribution of the mayonnaise product and withdrawing it from markets and food facilities across all cities in the Kingdom. They also include halting operations at the factory in preparation for implementing statutory procedures.

New Zealand – New reports highlight food recall system at work

MPI

A new report by New Zealand Food Safety identifies Salmonella in imported sesame seed-based products as the most significant food safety event of 2023, resulting in 14 recalls affecting 65 food products.

The ‘Consumer-level food recalls annual report for 2023’, one of 2 recall reports published by New Zealand Food Safety today, says the recalls were initiated after Salmonella was detected during routine testing by a New Zealand business making products containing tahini.

“A complex investigation by our Food Compliance Services team – involving product testing and tracing of ingredients through the domestic market – found the contamination was from tahini imported from a Turkish manufacturer,” says New Zealand Food Safety deputy director-general Vincent Arbuckle.

“The team dug deeper and subsequent online surveillance and scanning of international food safety issues also identified concerns with products from a manufacturer in Jordan.

“By the time all the sesame seed-based products were tracked down and removed from sale, we had supported 14 recalls affecting 65 products. And, most importantly, we had no confirmed reports of related illness.”

The annual reports are a new initiative by New Zealand Food Safety to share information on consumer-level recalls with the public.

“Our priority is to protect consumers, and these reports help identify trends and find ways to prevent food safety incidents,” says Mr Arbuckle.

“New Zealand’s food safety system has a strong track record of keeping people safe and – given the volumes of food being produced, manufactured and imported – incidences of related illness remain rare.

“However, there are occasions when food safety issues occur, and that’s when we work quickly with food businesses to recall the affected product, removing it from the food supply chain and promoting public awareness.”

The 2023 report shows New Zealand Food Safety supported food businesses to conduct 70 consumer-level food recalls.

“It’s important to note that the number of recalls is not an accurate indicator of the level of risk to consumers. Numbers are dependent on many factors, including regulatory changes, business and public awareness of food-related problems, and reporting of those problems,” says Mr Arbuckle.

Of the 70 recalls, 48 were initiated for domestically produced foods and 22 were for imported foods.

“Another food safety event to highlight from 2023 was the possible presence of Listeria and Campylobacter in raw milk, which led to 3 recalls.

“Drinking raw milk carries inherent risks as it may contain harmful bacteria that would normally be killed through the pasteurisation process.

“In this case, there were fortunately no associated reports of Listeriosis, which can be very serious for vulnerable people like the very young, pregnant, older and those with low immunity. But we were notified of 3 related cases of Campylobacter, which causes vomiting, diarrhoea, abdominal pain, fever, headache, and body aches.”

Allergens in food were the leading cause for recalls in 2023, with milk being the allergen that triggered the most recalls.

“Food recalls are a sign that our food safety system is working to protect consumers,” says Mr Arbuckle. “You can help keep yourself and your family safe by subscribing to our recall alerts from the New Zealand Food Safety food recall page.”

  • 70 consumer-level recalls in 2023

Symptoms of E. coli

Symptoms include severe stomach cramps, diarrhea, fever, nausea, and/or vomiting. Symptoms begin anywhere from a few days after consuming contaminated food or up to nine days later.

The severity or presence of certain symptoms may depend on the type of pathogenic E. coli that is causing the infection. Some infections can cause severe bloody diarrhea and lead to life-threatening conditions, such as a type of kidney failure called hemolytic uremic syndrome (HUS), or the development of high blood pressure, chronic kidney disease, and neurologic problems.

Stores Affected

Recalled organic walnut halves and pieces were sold in bulk bins at natural food and co-op stores in AK, AR, AZ, CA, CO, HI, ID, KS, LA, MT, NE, NM, NV, OR, SD, TX, UT, WA, and WY. A full list of store names and locations is available.
