England – Preston primary school shuts nursery after STEC E.coli cases in classrooms

Lancashire Post

Eldon Primary School said it has temporarily closed its nursery while children are tested for the bacterial infection and several deep cleans are carried out.

It comes after a small number of STEC (Shiga toxin-producing Escherichia coli) infections were confirmed among children who attend the nursery.

USA – Wedding from Hell in Idaho – STEC E.coli

Food Poison Journal

An outbreak of suspected enterotoxigenic E. coli (ETEC) was investigated by the Idaho Department of Health (the state) and the Southwest District Health Department (SWDH). The suspected outbreak was reported to the investigating agencies by August 31, 2022. The outbreak was given the state ID “2022-076.”

On August 30, 2022, the Southwest District Environmental Health Department (EH) received a phone call to notify them of a possible foodborne illness outbreak related to a wedding over the weekend. The caller was the father of the groom, who described around 15 people that he knew with diarrhea. On August 31, EH spoke with the groom and received more information. After this conversation, EH notified the epidemiology department, who again called and interviewed the groom about the event, the food, the activities on site, and others known to be ill. The information gathered from the groom over the phone is as follows:

Research – Safety Properties of Escherichia coli O157:H7 Specific Bacteriophages: Recent Advances for Food Safety

MDPI

Abstract

Shiga-toxin-producing Escherichia coli (STEC) is typically detected on food products mainly due to cross-contamination with faecal matter. The serotype O157:H7 has been of major public health concern due to the severity of illness caused, prevalence, and management. In the food chain, the main methods of controlling contamination by foodborne pathogens often involve the application of antimicrobial agents, which are now becoming less efficient. There is a growing need for the development of new approaches to combat these pathogens, especially those that harbour antimicrobial resistant and virulent determinants. Strategies to also limit their presence on food contact surfaces and food matrices are needed to prevent their transmission. Recent studies have revealed that bacteriophages are useful non-antibiotic options for biocontrol of E. coli O157:H7 in both animals and humans. Phage biocontrol can significantly reduce E. coli O157:H7, thereby improving food safety. However, before being certified as potential biocontrol agents, the safety of the phage candidates must be resolved to satisfy regulatory standards, particularly regarding phage resistance, antigenic properties, and toxigenic properties. In this review, we provide a general description of the main virulence elements of E. coli O157:H7 and present detailed reports that support the proposals that phages infecting E. coli O157:H7 are potential biocontrol agents. This paper also outlines the mechanism of E. coli O157:H7 resistance to phages and the safety concerns associated with the use of phages as a biocontrol.

Canada – E. coli O157 outbreak at Calgary daycare centres is over, Alberta Health Services says

CBC

The E. coli outbreak that was declared in September and infected hundreds of kids at several Calgary daycares is now over, Alberta Health Services (AHS) said in a release on Tuesday.

A total of 11 sites, including six branches of the daycare service and five other locations that shared a central kitchen, have been declared outbreak-free, AHS said.

The outbreak left 38 kids and one adult hospitalized. Doctors diagnosed 23 patients with severe illness or hemolytic uremic syndrome while eight received peritoneal dialysis.

No fatalities were reported and all patients have been discharged from the hospital, AHS said, adding that 1,581 kids who were linked to the outbreak have now been cleared by doctors to return to daycare.

Central kitchen still closed

USA – FDA – Investigations of Foodborne Illness Outbreaks

FDA

What’s New

  • A new outbreak of E. coli O121:H19 (ref # 1195) in a not yet identified product has been added to the table. FDA has initiated traceback.
  • For the outbreak of Listeria monocytogenes (ref # 1172) linked to Ice cream, the advisory was updated on October 26, 2023. The outbreak has ended, and FDA’s investigation is closed.

Norway -Updated: Serious E. coli outbreak is not over.

FHI

There is still a serious outbreak caused by the stomach and intestinal bacteria E. coli (EHEC), which in the worst case can cause acute kidney damage in children, the elderly and people with compromised immune systems. Infection has so far been detected in 24 people. More than half of those infected are children under the age of 13, and 9 of these have developed serious illness.

The outbreak is still ongoing. Infection has so far been detected in 24 people. They fell ill from July to October 2023 and all are infected in Norway. They are aged 1 to 55 and live in Trøndelag (15), Viken (4), Vestfold and Telemark (2), Innlandet (1), Møre and Romsdal (1) and Nordland (1). 15 of the infected are under the age of 13. Nine of the children have developed the serious complication haemolytic uraemic syndrome (HUS).

There is close cooperation between the Institute of Public Health, the Norwegian Food Safety Authority, the Veterinary Institute and the concerned municipal chief medical officers. The outbreak bacterium has been found in hamburger, but other minced meat and stuffing products where the same raw materials have been used have also been withdrawn. The tracking work is complicated, and the Norwegian Food Safety Authority cannot rule out that more products may be withdrawn from the market. FHI clarifies that it is therefore very important that people follow the advice for good food hygiene. 

Research -Nestlé outbreak drives record HUS high in France

Food Safety News

The number of children who suffered a potentially fatal complication of E. coli infection in France reached a record high in 2022, influenced by the Nestlé pizza outbreak, according to statistics recently released.

Hemolytic uremic syndrome (HUS), which can be a complication of E. coli infection, is a type of kidney failure that can result in lifelong, serious health problems and death.

In the outbreak caused by frozen Buitoni Fraîch’Up pizzas, 59 patients had a median age of 6. They fell ill between January and April 2022. Two children died.

Record HUS high
The 253 HUS cases in 2022 are the most since surveillance began in 1996. In 2021, 128 cases were reported. Santé publique France surveillance data on HUS only covers those younger than 15.

The sharp increase in incidence was partly driven by several outbreaks, including the one large Nestlé incident, but was also because of a lot of sporadic cases.

USA – Another 4 reported STEC E. coli cases bring total sick to 17 linked to 4S Ranch restaurant

NBC San Diego

Four more people have reported being sickened by an E. coli outbreak linked to Miguel’s Cocina in the 4S Ranch community of San Diego within the past two days, bringing the total to 17 cases, county health officials said Thursday.

Seven people had to be hospitalized, including four children, according to the county’s Health and Human Services Agency.

“The joint public health and environmental health investigation is ongoing,” HHSA spokesperson Fernanda Lopez said.

Those who fell ill, or their families, reported eating at Miguel’s 4S Ranch location from Oct. 6 to Oct. 18 and developed symptoms from Oct. 13 to Oct. 19, according to the HHSA.

County health officials are still investigating the specific food items that were the source of the Shiga-toxin-producing E. coli (STEC) at the restaurant. Miguel’s voluntarily closed its doors on Tuesday and has been working closely with the County to identify the outbreak.
