E. Coli Intestinal Infection. E. coli (Escherichia coli) is a common bacteria found in the environment, foods, and intestines of people and animals. There are a few types (strains) of E. coli. Most are harmless. But some types are harmful. They can cause severe illness because they make a toxin called Shiga Prevention . E. coli is spread through the fecal-oral route, meaning tiny particles of fecal matter that contain E. coli are ingested by a person—usually through food or water—and they then become ill. Although it sounds disgusting, it is quite common and it is how most foodborne illnesses are spread.  In total, 8 enterohaemorrhagic E. coli (EHEC) cases and 8 HUS cases were reported since 22 June. E. coli O104:H4 infection has been confirmed in 4 cases.
