What is Listeria?
Listeria are bacteria that can cause a serious illness called Listeriosis in some people. Listeriosis is usually caused by eating food contaminated by certain types of listeria bacteria. The listeria bacteria are found widely in nature. Storing contaminated foods, even in the refrigerator, may allow the listeria bacteria to grow. The bacteria may be present in raw foods or may contaminate food after it has been cooked or processed.
Listeria can contaminate food and cause infection which in pregnancy can lead to:
- premature birth
- a baby that is very sick at birth
Symptoms in adults range from mild (fever, headaches, tiredness, aches and pains) to severe (septicemia, meningitis) but note that it is very rare.
Cat poo and cat litter can contain the toxoplasmosis parasite which should be avoided (wear gloves and wash hands). Also always cook meat thoroughly and wash salad vegetables.
By following these simple steps you can reduce the risk to yourself and your unborn child. You should ask your specialist obstetrician if you are in doubt whether a particular food has known risks to your pregnancy.
