Listeriosis is an illness caused by eating raw, frozen, and ready-to-eat foods that have been contaminated with a bacterium called Listeria monocytogenes, or simply Listeria. Listeriosis is rare but can cause severe symptoms and even death in highly susceptible groups.
How can I be exposed to this infection?
Listeria is widespread and can poison many foods. Of greater concern are foods that do not require further cooking or reheating, such as frozen ready-to-eat foods.
How do I know that I have been infected with Listeriosis?
Infection in healthy adults is usually asymptomatic, or presents as a flu-like illness. However, in certain people, including the elderly, pregnant women and their unborn babies, newborn babies and people with weakened immune systems, it can cause serious illness and even death. A person who has been affected by Listeria infection may have symptoms such as: high fever, chills and headache. It happens that the symptoms are mild, so the presence of the infection is not understood. If you are concerned about symptoms or illness, please consult your family doctor.
How can infection be prevented?
You can reduce your risk of getting the infection by eating fresh, freshly cooked or prepared foods, and by avoiding foods that may have Listeria.
