Batches of organic eggs stocked at Woolworths, IGAs and other independent stores are being recalled due to potential salmonella contamination.

It is the third recall of eggs from NSW supermarket shelves this year, following separate salmonella concerns for other egg suppliers in February and March.

The NSW Food Authority issued an alert on Saturday advising that Southern Highland Organic Eggs were being recalled by supplier Synergy Produce Pty Ltd.

The recall covers both the 300g (6-pack) and the 700g (12-pack) of Southern Highland Organic Eggs, with best before dates up to and including May 9 2019.
