Listeriosis is a serious infection caused by the bacterium Listeria monocytogenes. It can cause a variety of symptoms, including fever, muscle aches, nausea, vomiting, and diarrhea. In severe cases, it can lead to meningitis, encephalitis, or even death. Listeriosis is most commonly spread through the consumption of contaminated food, such as unpasteurized milk, soft cheeses, and deli meats.
Pregnant women, newborns, the elderly, and people with weakened immune systems are at highest risk for developing listeriosis. The infection can be particularly dangerous for pregnant women, as it can cause miscarriage, stillbirth, or premature birth.
