Clinical Information
  • A bacterial infection caused by listeria monocytogenes. It occurs in newborns, elderly, and immunocompromised patients. The bacteria are transmitted through ingestion of contaminated food. Clinical manifestations include fever, muscle pain, respiratory distress, nausea, diarrhea, neck stiffness, irritability, seizures, and lethargy.
  • Gram positive bacterial infection with the genus listeria including listeria meningitis which causes clinical manifestations including fever, altered mentation, headache, meningeal signs, focal neurologic signs, and seizures.
  • Infections with bacteria of the genus listeria.
  • Listeriosis is a foodborne illness caused by listeria monocytogenes, bacteria found in soil and water. It can be in a variety of raw foods as well as in processed foods and foods made from unpasteurized milk. Listeria is unlike many other germs because it can grow even in the cold temperature of the refrigerator. Symptoms include fever and chills, headache, upset stomach and vomiting. Anyone can get the illness. But it is most likely to affect pregnant women and unborn babies, older adults, and people with weak immune systems. To reduce your risk
    • use precooked and ready-to-eat foods as soon as you can
    • avoid raw milk and raw milk products
    • heat ready-to-eat foods and leftovers until they are steaming hot
    • wash fresh fruits and vegetables
    • avoid rare meat and seafood
