UK-wide Salmonella Outbreak Linked to Imported Eggs Claims One Life, Over 200 Ill

One person has died and more than 200 others have fallen ill during a UK-wide outbreak of salmonella linked to people eating imported eggs. The UK Health Security Agency (UKHSA), leading the investigation, reports the 207 affected individuals range in age from under one to 90 years old. Most cases (199) are in England, with six in Scotland, and one each in Wales and Northern Ireland. London and Yorkshire & the Humber are the most affected areas with 47 and 38 cases, respectively.

The agency has ruled out UK-produced eggs or poultry, indicating the outbreak is tied to imported eggs. Whole-genome sequencing confirms all cases are linked to a single salmonella strain. The first case was identified on August 11, 2025, but most were reported from mid-last month. At least 34 people were hospitalized, with two developing bloodstream infections.

Dr. Safi Rehman, a King’s College London research associate, noted this outbreak is closely related to a 2025 incident also linked to imported eggs, with a genetically similar strain. The UKHSA, in a public notice, stated extensive investigations are ongoing to identify the contamination source. Interviews with 114 ill individuals identified five food businesses (supplying 24 cases) that received eggs from multiple sources, including importers. Local investigations found potential cross-contamination in two settings.

Hannah Charles, UKHSA’s lead epidemiologist, advised the public to wash hands thoroughly, cook food properly, and avoid handling food if symptomatic. She emphasized salmonellosis is usually mild but can be severe in vulnerable groups, with symptoms including diarrhoea, stomach cramps, vomiting, and fever.

The UKHSA is working with European countries through a joint health surveillance system to trace the outbreak’s origin. Details of the fatality cannot be released due to the ongoing investigation.
