Listeriosis is a rare but serious illness usually caused by eating food contaminated with the bacteria called Listeria monocytogenes. Anyone who experiences fever and muscle aches, sometimes preceded by diarrhea or other gastrointestinal symptoms, or develops fever and chills after eating any of the products described above, should seek medical care.

Symptoms can appear from a few days up to a few weeks after consumption of the contaminated food. Listeriosis can be fatal, especially in certain high-risk groups. These groups include the elderly and people with weakened immune systems and certain chronic medical conditions (such as cancer). In pregnant women, listeriosis can cause miscarriage, stillbirth, premature labor, and serious illness or death in newborn babies.

People who think they might have symptoms of listeriosis should consult their health care provider.
