Woolworths, IGA, ALDI, Campbells and other independent grocery stores have been instructed by the Food Standards Australia and New Zealand to pull varieties of frozen vegetables from their shelves due to fears they could be contaminated by listeria.

Scientist Gary Kennedy from the Australian Institute of Food Science and Technology said the recall was a necessary but cautious as the risk of illness was only present if frozen vegetables with listeria were consumed uncooked.

Mr Kennedy said to make sure you don’t get sick from frozen vegetables, they must be cooked to over 75 degrees celsius to kill listeria.
