Acute Communicable Disease Control
Listeriosis, Nonperinatal
Listeriosis is a disease transmitted primarily through consumption of
food contaminated with Listeria monocytogenes, a gram-positive
bacterium. L. monocytogenes is found in soil and water, and can
contaminate raw foods (e.g., uncooked meats and vegetables), as well as
processed foods that become contaminated after processing (e.g., soft
cheeses and cold cuts). Unpasteurized (raw) milk and foods made from
unpasteurized milk may also contain the bacterium. Common symptoms of
listeriosis include fever, muscle aches, headache, nausea, diarrhea, and
neck stiffness. A case of nonperinatal listeriosis is one that occurs in
persons other than pregnant women and/or their fetuses, neonates, or
infants up to 42 days after birth. Historically, nonperinatal
listeriosis presents as meningoencephalitis and/or septicemia, primarily
affecting elderly and immunocompromised persons, such as those with
cancer or HIV, and those on immunosuppressive therapy.
