What is Listeria monocytogenes?

Listeria monocytogenes can cause a foodborne disease known as listeriosis. Symptoms after exposure to this bacteria may include fever, headache, vomiting and diarrhoea but healthy individuals rarely develop symptoms. However, the effect on high-risk individuals like pregnant women, newborns, the elderly and people with weakened immunity can be severe. The infection can result in bacterial invasion of blood and the brain, miscarriage, stillbirth or premature birth in severe cases. Listeria is rather unique in the sense that they can multiply in refrigerated foods that are contaminated.

High-risk food

Prepared salads, unpasteurised milk and their products, soft cheese, smoked and raw seafood, cold meats, pate, etc. are regarded as high-risk foods, as the bacteria are more frequently found in them. Susceptible individuals including pregnant women, newborns, the elderly and people with weakened immunity should avoid these high-risk foods.
