AgriSA says it’s experiencing a challenge in determining how big a problem Listeria is on farms as the source of the bacteria is unknown.
Consumers have been advised to thoroughly cook vegetables.
Listeriosis is described as a serious, but treatable and preventable disease caused by the bacterium, Listeria monocytogenes, and is widely distributed in nature. It can be found in soil, water and vegetation.
Animal products and fresh produce, such as fruits and vegetables, can also be contaminated from these sources.
AgriSA’s Requier Wait says they’re not sure how much damage Listeria has done on farms because it’s been found in other places outside of farms.
