A32.9: Listeriosis, unspecified

You have been infected with listeria.

You have become infected with certain bacteria. These bacteria are called listeria. Listeria occur for example in unwashed vegetables, raw milk or raw meat and fish. With a listeria infection, it is common to have no symptoms or only a few. But if the defense system is weak, it is possible to become seriously ill with listeria.

Listeria can for instance cause fever, muscle aches, vomiting and diarrhea.
