The Food Standards Agency has advised under-fives, over-65s, pregnant women, and those with underlying health conditions to avoid runny or undercooked eggs when eating out, after the UK Health Security Agency declared a national salmonella outbreak linked to imported eggs.
FSA chief scientific adviser Ian Young described the outbreak as unusually large and rapidly increasing. Salmonella causes gastroenteritis with symptoms including abdominal pain, diarrhoea, vomiting and fever, with children, older adults, and the immunocompromised most at risk of severe illness.
Experts advise consumers to buy eggs bearing the British Lion mark, produced from hens vaccinated against salmonella. The contaminated eggs are believed to have originated outside the UK and were mainly supplied to food service and catering businesses.
