Eating food with germs can make you very very sick. We call it food poisoning.

The food can have germs or bacteria inside it. When it gets inside your body it can make you vomit, or have diarrhea, or run a fever.

You can get sick enough to die with food poisoning sometimes.

This is what bacteria look like. They are very very small, so small that you can't see them just by looking.

You have to look under a powerful microscope.

Here you can see how germs or bacteria multiply. They grow very quickly from just a few, to many thousands. The more of them there are, the sicker you get!

So that is why we must be careful when we are handling food.
