Listeria Monocytogenes in Food

Listeria monocytogenes has recently been recognized as an important public health problem in the United States. Listeriosis is a serious infection caused by eating food contaminated with the bacterium.

Listeria monocytogenes is found in soil and water. Vegetables can become contaminated from the soil or from manure used as fertilizer. The bacterium has been found in a variety of raw foods, such as uncooked meats and vegetables, as well as in processed foods that became contaminated even after processing, such as soft cheeses and cold cuts.
