Listeria infection is a rare infection acquired by infected food. The bacteria Listeria monocytogenes is found in soil and therefore it is in most animals. People acquire this bacterium by foodstuffs, especially soft cheese, milk, meat pate, or salads, prepared for a longer period. The risk is higher if these foodstuffs are kept in inappropriate conditions. Bacteria proliferate in the intestines and spread in the blood flow. Thus, they can infect other organs.
