Manchester: (Web Desk) – Health authorities in the UK are investigating a national outbreak of Salmonella Enteritidis that has sickened 207 people over the past year, with one death linked to the outbreak.
According to the UK Health Security Agency (UKHSA), the confirmed cases were recorded between August 11, 2025 and August 1, 2026. The majority were reported in 2026, with cases identified across England, Scotland, Wales and Northern Ireland.
The investigation has identified a possible connection to imported eggs, particularly those used by restaurants, cafés and other food-service businesses. However, authorities have stressed that the precise source of contamination has not yet been established. There is currently no evidence linking the outbreak to eggs or poultry produced in the UK.
UKHSA said 95 of 114 interviewed patients reported eating food prepared outside their homes before becoming ill. The strongest food-related signal so far has involved egg-based dishes, while investigations continue across the supply chain.
The outbreak has affected people across all age groups. Most patients experienced gastrointestinal illness that resolved without long-term complications, but 38 percent of those for whom hospitalisation information was available were admitted to hospital. Two patients developed bloodstream infections, and one person died.
The Food Standards Agency (FSA) has advised people to maintain good food hygiene, including thoroughly washing their hands before and after handling eggs, eggshells or egg packaging. It also recommends thorough cooking and careful prevention of cross-contamination.
The FSA has said there is no change to its advice on eating UK-produced supermarket eggs. British Lion-marked eggs and eggs produced under the Laid in Britain scheme remain considered safe when handled appropriately.
Authorities are continuing to investigate the origin of the contamination and possible links between imported egg suppliers and affected food businesses.
