What preventive measures are most important to prevent listeriosis?

By Dra. Lydia Pilar Suárez.
Last Update: 09/24/2019

Listeriosis is caused by Listeria monocytogenes, which is transmitted through contaminated food and causes fever and a flu-like illness.

The most frequently contaminated products with which the pregnant woman must take special care are precooked meat, unpasteurized milk and/or dairy products, and shellfish.

It is recommended to cook raw foods of animal origin (meat, fish...) at high temperatures (> 50ºC) and avoid drinking milk without heat treatment. Carefully wash raw foods (vegetables, fruits...). Wash hands after handling raw food and wash kitchen utensils after handling raw food and before using cooked food.

Do not mix raw and cooked or ready-to-eat foods in the refrigerator and clean the refrigerator often.

Once opened, do not store too long cold cuts that require storage in the refrigerator (ham, turkey sausage, pork tongue, gelatin...).

Food leftovers and ready meals should be carefully reheated (> 50°C) before consumption.
