Listeria is a common bacterium (bug) which is widely found in dust, soil, water, plants, sewage and animal droppings. Most people are not harmed by it, but for pregnant women, older people and people with a lowered immunity, it can cause serious problems.
Listeria can be transmitted to pregnant women through infected food. The bug has been found in a variety of foods at all stages of preparation, from raw to well-cooked leftovers. Listeria will still grow on food which is stored in a fridge.
