Now the other side. Here's a second claim: some microorganisms are harmful. Only some are, but they're worth knowing about.
Food poisoning is sickness from harmful germs in food. Harmful bacteria can be on raw chicken, raw eggs, and undercooked meat.
An infection happens when harmful germs grow in the body. Bacteria can get in through a cut and make it red and sore.
Larger living things of all kinds can be harmed. Some microorganisms cause diseases in crops, and too many algae in a lake can use up the oxygen that fish need.
