Consumers are being warned that a small number of British eggs from three major supermarkets may be contaminated with Salmonella.
Affected eggs sold at some Sainsbury, Aldi and Asda stores can be identified by the batch code – 1UK15270 – and the best before date stamped on the eggshell.
Symptoms caused by Salmonella usually include fever, diarrhoea and abdominal cramps.
The Food Standards Agency (FSA) is advising consumers to thoroughly cook the eggs listed in the table until both yolks and whites are solid. This will kill any Salmonella and avoid risk of illness.
Consumers who wish to return the potentially affected eggs should contact the store where they bought them for further information.
Only the eggs sold at the stores in the table are affected. The advice does not apply to other eggs sold by these retailers, or to eggs sold at other shops.
The FSA says there is no need to change your shopping habits for eggs or your usual cooking habits for eggs not listed in the table.
Anyone who is concerned about symptoms should contact their GP or out of hours service.
