What is E. coli?
Escherichia coli (E. coli) is a bacteria commonly found in the intestines of humans and animals. While most strains are harmless and even beneficial to digestive health, some can cause serious illness.

Types of E. coli
There are several types of E. coli, but only a few are pathogenic. The most notable is Shiga toxin-producing E. coli (STEC), which is often associated with foodborne illnesses. It can lead to severe stomach cramps, diarrhea, and vomiting.
How E. coli Spreads
E. coli typically spreads through contaminated food or water. In the case of the McDonald’s outbreak, it is believed that the contamination may have occurred during the processing of meat used in the burgers.
