Consumers in NSW and Victoria have been warned not to eat the latest batch of eggs that have been recalled over possible salmonella contamination.

Synergy Produce has recalled six and 12 packs of Southern Highland Organic Eggs with best before dates up to and including May 9, The NSW Food Authority said on Saturday.

The eggs have been available for sale in Woolworths in NSW and Victoria, IGA in NSW and other independent retailers in NSW.

The authority said the recall was due to potential salmonella enteritidis contamination, which could cause illness.

It follows a number of recalls linked to a salmonella enteritidis outbreak, with NSW Health saying in March that 149 of the state’s residents had become unwell since it was first reported in May 2018.

“This latest farm was firmly on our radar because it is close to farms in which salmonella has recently been detected,” Australian Eggs Managing Director Rowan McMonnies said.

Some brands of eggs were last month recalled across NSW, Victoria, Tasmania and South Australia after salmonella was detected at Victoria’s Bridgewater Poultry.

People infected with salmonella commonly develop headaches, fever, stomach cramps, diarrhoea, nausea and vomiting, NSW Health says.
