UK health authorities have reported that the number of salmonella cases linked to imported eggs has risen to 474, with two deaths confirmed. The UK Health Security Agency (UKHSA) previously reported 207 cases last week, but the identification of two new infection clusters has increased the total count significantly. While some of these cases date back to August 2025, the majority have been recorded in recent months.
Genetic analysis shows that the bacteria involved in these cases are almost identical, pointing toward a common food source. The outbreaks involve three specific genetic clusters identified as t5.9411, t0.24068, and t5.9765. Of these, 259 cases and one death are linked to t5.9411, 38 cases and one death are tied to t5.9765, and 177 cases are associated with t0.24068. Although salmonella can be contracted at any time, these clusters suggest a persistent issue.
The outbreak has primarily affected England, particularly in London and the Yorkshire and Humber regions, though a small number of cases have also been reported in Scotland, Wales, and Northern Ireland. More than one-third of those infected have required hospital treatment, with patients ranging in age from babies to individuals as old as 92. Despite the severity for some, most people recover without medical intervention.
Experts note that evidence currently suggests people have fallen ill after consuming eggs while eating out, rather than through home cooking. Similar cases have been identified across Europe, including 106 in the Netherlands, 15 in Belgium, six in Germany, four in France, two in Austria, and one in Denmark. Investigations in the Netherlands have suggested a potential link to chicken meat rather than eggs, though the exact cause of the UK outbreak remains under investigation.
Prof Ian Young of the Food Standards Agency stated that they are working closely with the UKHSA and other partners, noting: "The exact causes of these outbreaks have not yet been identified, but investigations so far have identified links to imported eggs. There is no evidence that UK-produced eggs are affected." Officials emphasize that eggs bearing the British Lion mark or produced under the 'Laid in Britain' scheme are safe, as they adhere to strict testing and vaccination protocols.
Symptoms of salmonella, which typically appear 12 to 72 hours after infection, include fever, vomiting, diarrhea, and stomach cramps. The UKHSA advises anyone concerned to contact their GP or an out-of-hours service. To prevent infection, authorities recommend thorough food preparation and consistent handwashing.
