The NSW Food Authority has issued a warning on a batch of eggs over fears they may be contaminated with salmonella.

The eggs that may be contaminated are stamped with BEC or BEC115 on the shells, rather than on the carton containing them.

“It is important to know that not all eggs are impacted but if you have any stamped with BEC or BEC115 we recommend as a precaution that you discard them,” said Dr Lisa Szabo, the CEO of the NSW Food Authority.

“All other eggs are safe to eat, provided people exercise the usual caution required for a special care food like eggs such as washing your hands and avoiding raw egg products particularly if you are a vulnerable population such as the immune compromised, under two or over 70 years of age or pregnant.”

Symptoms of salmonella include fever, headache, diarrhoea, abdominal pain, nausea and vomiting.
