Listeriosis is an infection caused by eating contaminated food. The bacteria that makes people sick can be found in soil, water and animal stomachs. Vegetables can become contaminated through soil or contaminated manure. Other foods that can become contaminated are foods with long shelf life under refrigeration and foods that are eaten without being cooked (seafood, etc.). The infection is most likely to sicken pregnanat women and their newborns, adults aged 65 or older, and people with weakened immune systems.
