Rise in UK salmonella cases linked to imported eggs
UK health officials say the outbreak now includes three genetic clusters and one death, with investigations pointing to imported eggs.
The Health Security Agency reported 474 salmonella cases linked to imported eggs, including two deaths across three genetically distinct clusters identified since June.
Whole genome sequencing identified three bacterial clusters—t5.9411, t0.24068, and t5.9765—dating back to last year. Genetic analysis suggests a common food source, while officials confirm no evidence that UK-produced eggs are contaminated.
More than a third of those infected have required hospital care, with patients ranging from babies to 92-year-olds. Most individuals fell ill after eating out rather than preparing meals at home.
Professor Ian Young, chief scientific adviser at the Food Standards Agency, advised vulnerable groups to consume only thoroughly cooked eggs. Good hygiene remains the best protection against infection.
Cases identified in European nations including the Netherlands and Germany reveal the outbreak extends beyond Britain. This international pattern suggests a wider supply chain contamination issue.
