Bacteria get a lot of attention because some of them, a small amount, can make you sick or even kill you! They can also cause some really annoying illnesses like sore ears, nose, throat and eyes. They can also ruin food and be used to hurt people. Some infections can spread right inside your body and give you more serious diseases such as respiratory infections like pneumonia!
Bacterial in food can lead to digestive problems, an illness known as food poisoning. Raw eggs and undercooked meats commonly carry the bacteria that can cause food poisoning. Food poisoning can be prevented by cooking meat thoroughly, which kills most microbes, and washing surfaces that have been in contact with raw meat. Washing your hands before and after handling food also helps prevent contamination.
