    What Is Listeria Infection?

    Listeria is a bacteria primarily found in soil and water. According to the CDC, vegetables can become contaminated from soil or from manure used as fertilizer. Animals carrying the bacterium can also contaminate food. Listeria has been found in many types of uncooked foods, such as meats and vegetables, as well as in processed foods that become contaminated after processing, such as soft cheeses (like feta and crumbled blue cheese) and cold cuts.

    Unpasteurized milk or foods made from unpasteurized milk may also be sources of listeria infection. Listeria is killed by pasteurization, and heating procedures used to prepare ready-to-eat processed meats should be sufficient to kill the bacterium. However, unless good manufacturing practices are followed, contamination can occur even after processing.

    The CDC estimates 1,600 illnesses and 260 deaths from listeria infection each year. The CDC reports that those at increased risk for developing listeriosis include:

    Symptoms of a listeria infection can include:

    • Fever
    • Muscle aches
    • Nausea
    • Diarrhea

    Infected pregnant women may experience only a mild, flu-like illness; however, infection during pregnancy can lead to premature delivery, infection of the newborn, or even stillbirth. There is no routine screening test to find out if you are likely to contract listeria infection during pregnancy. If you have symptoms of listeriosis, consult your doctor immediately.
