The UK Health Security Agency (UKHSA) is investigating an outbreak of Shiga toxin-producing E.coli (STEC) cases in the UK in recent weeks, thought to be linked to a nationally distributed food item or multiple food items.
The UKHSA is investigating the cause of the E.coli cases alongside public health agencies in Scotland, Northern Ireland and Wales.
Infections caused by STEC bacteria can cause severe bloody diarrhoea and, in some cases, more serious complications.
It is often transmitted by eating contaminated food but can also be spread by close contact with an infected person, as well as direct contact with an infected animal or its environment.
Between May 25, 2024, and June 4, 2024, there have been 113 confirmed cases associated with this E.coli outbreak in the UK, the UKHSA said.
There have been 81 confirmed cases in England, 18 in Wales, 13 in Scotland and one in Northern Ireland (for this case, evidence suggests that the person acquired their infection while visiting England).
Whole genome sequencing of samples in the current investigation indicates that most cases are part of a single outbreak.
Based on the wide geographic spread of cases, it is most likely that this outbreak is linked to a nationally distributed food item or multiple food items, the UKHSA said.
The source of this outbreak is not yet confirmed but there is currently no evidence linking the outbreak to open farms, drinking water or swimming in contaminated seawater, lakes or rivers.
The public health agencies are working with the Food Standards Agency (FSA) and Food Standards Scotland to investigate further.
STEC can be carried by cattle, sheep and other animals. Spread to humans occurs through:
Typically, the UKHSA sees around 1,500 cases of STEC over a full year.
Numbers of confirmed cases associated with this outbreak are expected to rise as further samples undergo whole genome sequencing.
Cases range in age from 2 years old to 79 years old, with the majority of cases in young adults.
Of the 81 cases identified to date in England, 61 have provided information to UKHSA related to food, travel and potential exposures and of these, 61% have been hospitalised.
Incident director at UKHSA, Trish Mannes, said: “Symptoms of infections with STEC include severe and sometimes bloody diarrhoea, stomach cramps, vomiting and fever.
“NHS.UK has information on what to do if you have symptoms and when to seek medical advice.”
Mannes said washing your hands with soap and warm water and using disinfectants to clean surfaces will help stop infections from spreading.
“If you are unwell with diarrhoea and vomiting, you should not prepare food for others and avoid visiting people in hospitals or care homes to avoid passing on the infection in these settings,” she said.
Head of incidents and resilience at the FSA, Darren Whitby, said: “The FSA is working with UKHSA and relevant Public Health bodies to identify the source of the illness, which is likely to be linked to one or more food items.
“We always advise consumers and those looking after vulnerable people to ensure good hygiene practices are followed when handling and preparing food, regularly washing hands with soap and warm water and ensuring equipment, utensils and surfaces foods come into contact with are cleaned thoroughly to prevent cross contamination.
Head of health protection (infection services) for Public Health Scotland, Jim McMenamin, said: “To help stop infections like E. coli from spreading, we advise regular hand washing using soap and water, particularly after using the toilet and before preparing food.
“People should also use disinfectants to clean surfaces that may be contaminated. Anyone experiencing severe and sometimes bloody diarrhoea, stomach cramps, vomiting and fever should call their GP or 111 to seek advice.
Consultant in health protection for Public Health Wales, Wendi Shepherd, said: “Public Health Wales is working with partners in the UK and across the Welsh NHS to investigate this incident.
“There are currently 18 cases identified in Wales and healthcare providers have been advised of the increase in cases.
“We would advise anyone who has experienced bloody diarrhoea or severe stomach cramps to seek medical attention.”

STEC can be carried by cattle, sheep and other animals. Spread to humans occurs through:
- Consumption of contaminated food or water;
- Contact with animals or their faeces;
- Contact with a contaminated environment;
- Person-to-person spread, often resulting in multiple people in one household becoming infected.
