Salmonella cases cause egg withdrawal in New South Wales

An outbreak of salmonella infection has prompted the recall of eggs from Glendenning Farms.

The eggs are being removed from the stores in Sydney after discovering a group of Salmonella cases.

The NSW Food Authority said on Saturday that 23 cases of salmonella enteritidis had been confirmed in the city, prompting egg producer Eggz on the Run to voluntarily recall some products sold under the Glendenning Farm brand.

Consumers are advised not to consume entire whole Glendenning Farm eggs sold in New South Wales with the best dates of 8, 10, 15, 17, 22, 24, 29 or 1 October.

The products were sold in small independent supermarkets and retailers.

"O bin or return them to the place of purchase for a full refund," said the NSW Food Authority in a statement on Saturday.

"You do not need a proof of purchase of an item removed from the market."

Fever, headache, diarrhea, abdominal pain, nausea and vomiting are symptoms of salmonellosis and usually begin between six and 72 hours after the contaminated food has been ingested.

The illness can last seven days or more.

The government has restricted the movement of cattle, eggs, manure and disposable products on the farm and ordered the disinfection and decontamination of the equipment.

The investigations are still ongoing.
