A salmonella outbreak across the UK has led to one death and 207 people falling ill. Health officials have linked the outbreak to the consumption of imported eggs.
The UK Health Security Agency (UKHSA), which is investigating the outbreak, stated that those affected range in age from under one year to 90 years old. The agency has ruled out UK-produced eggs or poultry as the source, indicating that available evidence points to eggs imported into Britain.
The UKHSA is collaborating with other European countries through their joint health threat surveillance system to identify the outbreak's origin. While details of the deceased person are not being released due to an ongoing investigation, a number of individuals required hospital treatment for salmonellosis, with two developing bloodstream infections.
Whole-genome sequencing has confirmed that all 207 cases are linked to a single strain of salmonella. The first case was identified on 11 August 2025, though most cases have emerged since mid-July. England has reported 199 cases, Scotland six, and Wales and Northern Ireland one each. London accounts for 47 cases, and the Yorkshire and the Humber region 38.
Hannah Charles, UKHSA's lead epidemiologist for gastrointestinal infections, advised the public to wash hands thoroughly after using the bathroom and before preparing food, cook food thoroughly, and avoid handling food for others if experiencing symptoms.
