Open all pages about Listeriosis
Listeriosis is an infection caused by listeria bacteria. It's rare, but can cause serious problems if you're pregnant or have a weak immune system.
Listeriosis is usually caught from contaminated food. It's also possible to catch it from someone else who has it or from contact with farm animals.
Listeriosis does not always cause symptoms. If it's mild, it can cause flu-like symptoms including a high temperature, chills and diarrhoea.
If you're pregnant, you can reduce your risk of getting listeriosis by avoiding certain foods, including pâté and some uncooked soft cheeses.
