Belgium-based company Greenyard Frozen Belgium NV has recalled the frozen vegetables - which include frozen corn, carrot, broccoli and mixed vegetable bags - from Woolworths, IGA and ALDI stores.

"Following a worldwide product recall issued by the Hungarian Food Safety Agency, and purely as a precautionary measure, we are recalling our Woolworths Frozen Savoury Rice Mix product".

According to the EFSA, new cases could still emerge due to the extended incubation period of listeriosis (up to 70 days); the long shelf-life of frozen corn products; and the consumption of frozen corn bought before the recalls and eaten without being cooked properly.

Other frozen sweetcorn and vegetable products are not affected, the retailer added.

An FSA risk statement says: "The products listed above might be contaminated with Listeria monocytogenes. Thorough cooking would ensure that the product is safe".

The recalled vegies were sold at IGA, Aldi and Woolworths and include the brands Black and Gold, Bell Farms, Market Fare and Essentials.

Customers are being advised not to eat them, and instead return them to the store in exchange for a refund.

This after an ST6 strain of listeria was found at an Enterprise Foods facility in Polokwane.

In vulnerable people, listeriosis can be serious and fatal.

ALDI - Only products with country of origin of Belgium, United Kingdom or Hungary.

In pregnant women, symptoms can still appear mild but infection can cause miscarriage, stillbirth, pre-term labour, illness or death of newborns.

Woolworths said it proactively manages and prevents microbial contamination of food, and has very strict protocols in place.

"If you are a healthy adult you'd have to eat a lot of frozen vegetables to make you sick because most of the potentially unsafe bacteria is killed by the acid in your stomach", Mr Kennedy said.
