Escherichia coli

Escherichia coli (pronounced esh-uh-RI-kee-uh KOH-lie) is a type of small living thing that can be found in the intestines of many animals, including humans. It is like a tiny little creature that is so small that you cannot see it with your eyes.

Some types of Escherichia coli are actually good for you because they help your body break down food and absorb nutrients. However, there are some types that can make you sick if you get too much of them or if they get into the wrong parts of your body.

Escherichia coli can also be found in soil, food, and water. Sometimes, if these things are not cleaned properly or if you eat something that has gone bad, you might get sick because there are too many Escherichia coli in your body.

To keep yourself safe from getting sick from Escherichia coli, you should always wash your hands before eating or preparing food, cook your food thoroughly, and avoid drinking water that might be contaminated. If you do get sick, it is important to rest and drink lots of water to help your body fight off the infection.
