Severe bloody diarrhoea - new E. coli outbreak hospitalizes many

A concerning outbreak of a severe E.coli strain, known to cause ‘bloody diarrhoea,’ has potentially been traced to a widely distributed food product.

The UK Health Security Agency (UKHSA) has reported hospitalizations as a result of this grim infection. Public health bodies in Scotland, Northern Ireland, and Wales are also examining a surge in Shiga toxin-producing Escherichia coli (STEC) cases.

Whole genome sequencing of the samples suggests that the majority of the 113 reported cases in the UK since May 25 are linked to a single outbreak, according to the UKHSA.

A statement from the agency noted, “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.”

STEC infections can lead to severe bloody diarrhoea and, in some instances, more serious health complications. While contaminated food is a common transmission route, the infection can also spread through close contact with an infected person, or direct contact with an infected animal or its environment.

Since May 25, there have been 113 confirmed cases of this strain: 81 in England, 18 in Wales, 13 in Scotland, and one in Northern Ireland. The individual in Northern Ireland is believed to have contracted the infection while visiting England.

Trish Mannes, Incident Director at UKHSA, explained, “Symptoms of STEC infections include severe and sometimes bloody diarrhoea, stomach cramps, vomiting, and fever. If you experience diarrhoea and vomiting, there are measures you can take to prevent passing the infection to others. NHS.UK provides information on managing symptoms and when to seek medical advice.

“Washing your hands with soap and warm water and using disinfectants to clean surfaces can help prevent the spread of infections. If you are suffering from diarrhoea and vomiting, avoid preparing food for others and visiting people in hospitals or care homes to minimize the risk of spreading the infection. You should not return to work, school, or nursery until 48 hours after your symptoms have subsided.”

Annually, the UK typically records around 1,500 STEC cases. Darren Whitby, Head of Incidents and Resilience at the Food Standards Agency (FSA), stated, “The FSA is collaborating with the UKHSA and other public health organizations to identify the source of the outbreak, which is likely linked to one or more food items.

“We always advise consumers and caregivers to follow good hygiene practices when handling and preparing food. This includes regularly washing hands with soap and warm water and thoroughly cleaning equipment, utensils, and surfaces to prevent cross-contamination.

“Avoid preparing food for others if you have had symptoms, and wait 48 hours after symptoms stop before doing so. More information about good hygiene practices and E.coli can be found on our website.”
