What is Listeria?
Listeria monocytogenes is a type of bacteria that is found in water and soil. Vegetables can become contaminated from the soil, and animals can also be carriers. Listeria has been found in uncooked meats, uncooked vegetables, unpasteurized milk, foods from unpasteurized milk and processed foods. Listeria is killed by pasteurization and cooking. There is a chance that contamination may occur in ready-to-eat foods such as hot dogs and deli meats because contamination may occur after cooking and before packaging.
Can Listeriosis harm my baby?
If you are pregnant and are infected with Listeriosis, you could experience:
* Miscarriage
* Premature delivery
* Infection to the newborn
* Death to the newborn (only 22% of cases with perinatal Listeriosis result in stillbirth or neonatal death)
Early treatment may prevent fetal infection and fetal death.
Do not eat hot dogs, luncheon meats or deli meats unless they are properly reheated to steaming (or 160 F): Eating out at certain restaurants that provide deli meat sandwiches such as Subway is not recommended for pregnant women since they do not reheat their deli meats. Therefore Subway recommends that pregnant women eat non-luncheon meat items such as meatball, steak & cheese, roasted chicken, seafood & crab and tuna (limit 2 servings a week).
Do not eat refrigerated pates or meat spreads.
Do not eat refrigerated smoked seafood unless it is contained in a cooked dish, such as a casserole.
