In short
Listeriosis is a foodborne illness caused by Listeria monocytogenes, which are bacteria found in soil and water that can grow even in the cold temperature of a refrigerator. The bacteria can be present in a variety of raw foods, processed foods, and products made from unpasteurized milk. Symptoms of the illness include fever, chills, headache, upset stomach, and vomiting, and treatment is with antibiotics. While anyone can contract listeriosis, it is most likely to affect pregnant women, unborn babies, older adults, and individuals with weak immune systems.

Description
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. Treatment is with antibiotics.
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 refrigerated smoked seafood

About this page. This page brings together public information from official sources, each cited where it is used. It is not medical advice, it is not a diagnosis, and it does not tell you which treatment to take.
Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration). They describe what a medicine is approved for, not whether it is right for you. Approved uses can differ between countries. Always read the package leaflet and follow your doctor's or pharmacist's advice.
What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.
Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.
In an emergency, call 112 (or your local emergency number). Do not delay seeking medical help because of something you read here.
