If you eat food contaminated with bacteria called Listeria, you could get so sick that you have to be hospitalized. And for certain vulnerable people, the illness could be fatal.
Contaminated food can bring Listeria into the home. Unlike most bacteria, Listeria germs can grow and spread in the refrigerator. So if you unknowingly refrigerate Listeria-contaminated food, the germs could contaminate your refrigerator and spread to other foods there and increase the likelihood that you and your family will become sick.
Those most at risk for listeriosis—the illness caused by Listeria monocytogenes—include pregnant women, older adults and people with compromised immune systems and certain chronic medical conditions (such as HIV/AIDS, cancer, diabetes, kidney disease, and transplant patients). In pregnant women, listeriosis can cause miscarriage, stillbirth, and serious illness or death in newborn babies.
Recently, a multi-state outbreak of listeriosis tied to contaminated cantaloupes has caused illnesses and deaths. Listeria has also been linked to a variety of ready-to-eat foods, including unpasteurized milk and dairy products, Mexican-style or soft cheeses made with unpasteurized milk, processed deli meats, hot dogs, smoked seafood and store-prepared deli-salads.
Donald Zink, Ph.D, senior science advisor at FDA’s Center for Food Safety and Applied Nutrition, says FDA is aware of cases of foodborne illness caused by bacteria that can live in the kitchen and spread to foods.
Consumers are advised to wash all fruits and vegetables under running water just before eating, cutting or cooking, even if you plan to peel the produce first. Scrub firm produce such as melons and cucumbers with a clean produce brush.
