Listeria Facts

Symptoms of Listeriosis

It is important for you to recognize the early signs of infection in order to prevent its progression. The signs which you must keep under check include fever, muscle ache, and at times diarrhea or other gastrointestinal problems. Besides these, other symptoms are headache, confusion, and convulsions.

Almost all patients suffering from listeriosis have infection spread beyond the gastrointestinal tract. When the infection attacks pregnant women, it puts them at a risk of miscarriage, premature delivery or infection of the baby.

Prevention is Better than Cure

Although you can get yourself treated for infection with the help of antibiotics, it is always advised to prevent the disease first. As the infection spreads through eating contaminated food, make sure your meat is properly cooked. Cleaning of raw fruits and vegetables must be done thoroughly before consuming.

Make sure that raw meat and poultry food items are kept separately from vegetables and other cooked foods. Avoid drinking unpasteurized milk or eating foods that contain unpasteurized milk.

Maintain proper hygiene. Wash your hands, utensils, and countertops before cooking food.

For People who are at High Risk:

  • Avoid eating hot dogs, cold cuts, other deli meats, or fermented or dry sausages until they are cooked properly.
  • Do not eat refrigerated meat spreads.
  • Do not consume soft cheese if it is not made with pasteurized milk.
  • Avoid refrigerated smoked seafood if it is not in a cooked dish or is canned.


Keeping a check on the food you eat and the way you cook would make a lot of difference when it comes to preventing the infection.
