Salmonella has long been a concern when it comes to food poisoning, affecting vulnerable groups including the very young, very old and pregnant women. Due to a large outbreak in England, the Food Standards Agency has advised pregnant women and young children not to consume raw or partially cooked eggs outside of the home as the supply chain may be unclear.

The general recommendation for all vulnerable groups is to avoid raw or partially cooked eggs that do not have the Lion mark or the ‘Laid in Britain’ mark on them. This is because eggs without these marks may not have been laid by vaccinated hens. The FSA has advised women can have raw or partially cooked Lion or Laid in Britain eggs at home.
