Listeria is a bacterial illness that occurs when you eat food that is improperly processed, such as hot dogs and deli meats. Even if you freeze and refrigerate your food, listeria can still grow. Pregnant women, newborns, and individuals with a weak immune system are at a higher risk of developing listeria.
Healthy people don’t have to worry too much about falling ill to listeria. They can still have listeria, but it won’t affect them. Even if they do have symptoms, they are mild. Individuals who are at a higher risk of developing listeria need to seek medical attention quickly. The longer you wait to seek treatment, the more difficult it will be to treat it. It can cause death in individuals that are at a higher risk. You can avoid listeria by not eating unprocessed foods and washing your hands at every chance you get to avoid being exposed.
