UK health authorities are investigating a salmonella outbreak that has affected 207 individuals over the past year, with the majority of cases occurring in recent weeks. One person has died from the infection, and more than one-third of those affected required hospitalization. Two patients developed serious blood poisoning as a complication. The outbreak involves a specific, identical strain of the bacterium that experts believe is linked to consumption of food prepared with imported eggs.
The geographic distribution of confirmed cases shows 199 cases in England, including 47 in London and 38 in Yorkshire and Humber, along with six cases in Scotland, one in Wales, and one in Northern Ireland. Affected individuals range in age from infants to those as old as 90. The UK Health Security Agency notes that most patients recover without medical intervention, though symptoms including stomach cramps, diarrhea, vomiting, and fever typically develop between 12 and 72 hours after infection.
Investigations by the UK Health Security Agency and Food Standards Agency are ongoing to identify the source. Evidence suggests people became ill after consuming food at restaurants and catering establishments rather than home-prepared meals. Some food businesses linked to 24 cases use imported eggs in their operations. Authorities have found no identified link to UK-produced eggs or poultry at this time. Health officials note that while salmonella cases occur regularly in the UK from various sources, outbreaks caused by a single strain affecting numerous individuals simultaneously are less common.
Public health guidance emphasizes that thorough cooking and proper food handling can prevent infection. Vulnerable populations including infants, young children, pregnant individuals, and older adults are advised to consume only eggs with the British Lion mark or those from the Laid in Britain assurance scheme if eating runny or raw eggs. The Food Standards Agency and health experts recommend checking catering outlet hygiene ratings and maintaining careful hand hygiene when handling eggs and egg packaging.
