A salmonella outbreak linked provisionally to imported eggs has sickened more than 250 people across seven European countries and has been associated with one death in Britain. UK health officials say the overall public risk remains low, but the outbreak matters because a substantial proportion of affected UK patients required hospital treatment and some developed bloodstream infections.

UK cases rose from 207 at the start of the month to more than 250, an increase of about 25 per cent, with 52 additional cases reported in the latest week. Investigators have linked cases to meals from cafés, restaurants and takeaways; imported eggs used in catering are the main focus, although chicken products are also being examined. The FSA says there is no evidence UK-produced eggs are affected and advises thorough cooking, hygienic handling and extra caution with runny eggs for vulnerable people.
