Due to the long incubation period, it is challenging to identify the food which was the actual source of the infection. High risk foods include deli meat and ready-to-eat meat products (such as cooked, cured and/or fermented meats and sausages), soft cheeses and cold smoked fishery products. Listeria bacteria can be found in soil, water and animal feces. Outbreaks of this disease have generally involved the ingestion of foods containing high doses of L. monocytogenes. People with HIV/AIDS are at least 300 times more likely to get ill than those with a normally functioning immune system.
