Eggs are being recalled from shops in Sydney after a cluster of salmonella cases were uncovered.
NSW Food Authority on Saturday said 23 cases of salmonella enteritidis had been confirmed in the city, leading to egg supplier Eggz on the Run to voluntarily recall some products sold under the Glendenning Farm brand.
Consumers are advised not to consume any Glendenning Farm whole shell eggs sold in NSW with best before dates of September 8, 10, 15, 17, 22, 24, 29 or October 1.
The products were sold in small independent supermarkets and retailers.
"Either bin or return them to the place of purchase for a full refund," NSW Food Authority said in a statement on Saturday.
"You do not require proof of purchase for a recalled item."
Fever, headache, diarrhoea, abdominal pain, nausea and vomiting are symptoms of salmonellosis and usually start about six to 72 hours after the contaminated food is eaten.
Illness can last seven days or longer.
The government has restricted the movement of livestock, eggs, manure and disposables at the farm and ordered the disinfection and decontamination of equipment.
Investigations are still ongoing.
