Listeria monocytogenes
Listeria monocytogenes is a type of bacteria that can cause an infection called listeriosis. It is found in soil, water, and some foods, especially unpasteurized dairy products, deli meats, and smoked seafood. When people eat contaminated food, they may develop symptoms like fever, muscle aches, and sometimes diarrhea. In vulnerable groups such as pregnant women, older adults, and those with weakened immune systems, listeriosis can be more severe, leading to complications like meningitis or miscarriage. Proper food handling, thorough cooking, and avoiding high-risk foods help prevent infection.
