Understanding Listeria
Listeria monocytogenes is a bacterium that causes listeriosis. The illness most often affects adults over age 65, pregnant women, newborns, and people with weakened immune systems. Common listeriosis symptoms include fever, nausea, diarrhea and muscle cramps. Listeriosis infection in more serious cases in the nervous system causes headache, stiff neck, confusion, loss of balance, and convulsions.
