What is Escherichia coli?
Escherichia coli, often called simply E. coli, is a group of bacteria. There are different types of E. coli. Some types normally live in your intestines. If these E. coli get into other parts of your body, you can get sick. If other types of E. coli get into your intestines, you can also get sick.

What causes E. coli infections?
You can get an E. coli infection in your intestines if you:
Cooked food can have E. coli in it if it wasn't cooked properly. Fresh food, such as salads, can have E. coli if it was washed in dirty water.
Touching animals in petting zoos sometimes spreads E. coli.
Different countries have different types of E. coli. If you travel to another country, you may get sick from the E. coli that are common in that country (see Traveler's Diarrhea).
