Health authorities across the UK are urgently investigating a growing E.coli outbreak that has sickened more than 100 people and sent at least 37 to hospital. Experts warn the infection may spread further as the country heads into peak barbecue season.
The illness is caused by Shiga toxin-producing E.coli (STEC), a rare but aggressive strain known to trigger severe stomach cramps, vomiting, and fever. Officials say the infections are scattered across all four UK nations, suggesting the source may be a widely distributed food product.
Symptoms have hit people of all ages, including young children and older adults. Many patients have required hospital care due to dehydration and complications.

Among those hospitalized is 76-year-old Christopher Holmes of Kent. His daughter reported that he fell ill despite being careful with food safety and hygiene at home. Doctors later confirmed STEC, and he was moved to an isolation unit. He is expected to be discharged once the infection clears.
Food safety experts have urged the public to be extra cautious when storing, preparing, and cooking food. Undercooked meat—especially burgers—raw produce, and unwashed vegetables are common sources of contamination. STEC can also spread through contact with infected animals, contaminated water, or poor hand hygiene.

Health officials warn that only a small number of bacteria are needed to cause illness.
Brits are advised to:
- Wash hands thoroughly with soap and warm water.
- Cook meat completely, with no pink inside.
- Avoid preparing food for others while sick.
- Stay home from work or school for at least 48 hours after symptoms stop.
Anyone experiencing persistent vomiting, bloody diarrhoea, or signs of dehydration—especially in young children—should contact NHS 111 or their GP.
The UK Health Security Agency continues to work with food safety specialists to identify the source of the outbreak.
