Australia’s egg industry has been hit by yet another salmonella scare, with a recall notice issued for several batches of eggs sold in New South Wales.

Food Standards Australia New Zealand on Wednesday announced Ash and Son Eggs had issued a recall notice for a range of its products, with two best before dates, sold in IGA supermarkets, independent stores, butchers and bakeries across the state.

There is the risk the eggs could be contaminated with salmonella.

It follows a recall from last week from Victorian farm Bridgewater Poultry, due to the same fears.

Australian Eggs, the national body for the product, said the farm’s owners had undertaken voluntary testing for the disease strain, and as such, the farm was now quarantined.

“Australian Eggs has been working closely with government authorities to identify supply chain links between farms after [salmonella enteritidis] was identified in egg products last week,” managing director Rowan McMonnies said.

“This latest farm was firmly on our radar because it is close to farms in which salmonella has recently been detected.”

Salmonella is a gastro infection that mostly comes from eating undercooked or raw contaminated meat, poultry and eggs. It can also be transmitted from person to person.

Its symptoms include fever, headache, diarrhoea, stomach pain, nausea, and vomiting, and can appear anywhere between six and 72 hours after a person comes into contact with the bacteria. They usually last between four and seven days.

In young children, the elderly and people with lowered immune systems, it can cause serious illness and has the potential to be fatal.

Anyone who is concerned about their health after eating the potentially contaminated products is urged to seek medical attention immediately.
