Listeria is a type of bacteria found everywhere in soil and ground water and on plants. Animals and people can carry Listeria in their bodies without becoming sick. Despite being so widespread, most infections in humans result from eating contaminated foods.
Most people are not at increased risk for listeriosis. However, there are some people who are considered at risk because they are more susceptible to listeriosis. In addition to pregnant women and their unborn babies and newborns, other at-risk groups include older adults and people with weakened immune systems caused by cancer treatments, AIDS, diabetes, kidney disease, etc. By carefully following food safety precautions, persons at risk for listeriosis can substantially reduce their chances of becoming ill.
