A32: Listeriosis

Listeriosis is a serious infection caused by the bacteria Listeria monocytogenes. People usually contract this illness after consuming contaminated food, especially raw or undercooked meats, unpasteurized dairy products, and improperly washed fruits and vegetables. Pregnant women, newborns, older adults, and individuals with weakened immune systems are particularly susceptible. Oftentimes, symptoms of listeriosis can seem flu-like, such as fever, muscle aches, and sometimes gastrointestinal problems. However, if the infection spreads to the nervous system, it can cause headaches, a stiff neck, confusion, loss of balance, or convulsions. If contracted by a pregnant woman, listeriosis can lead to miscarriages, stillbirths, premature delivery, or a potentially life-threatening infection of the newborn. Listeriosis generally progresses over days to weeks and can be severe, affecting various systems in the body.
