E. coli is the name of a type of bacteria that lives in your intestines and in the intestines of animals. Although most types of E. coli are harmless, some types can make you sick.
The worst type of E. coli, known as E. coli O157:H7, causes bloody diarrhea and can sometimes cause kidney failure and even death. E. coli O157:H7 makes a toxin called Shiga toxin and is known as a Shiga toxin-producing E. coli (STEC). There are many other types of STEC, and some can make you just as sick as E. coli O157:H7.
One severe complication associated with E. coli infection is hemolytic uremic syndrome (HUS). The infection produces toxic substances that destroy red blood cells, causing kidney injury. HUS can require intensive care, kidney dialysis, and transfusions.
|E. coli O121 Multistate Outbreak|
CDC is investigating an outbreak of E. coli O121 infections in several states. Twenty-seven ill people have been identified in 15 states, and 8 people have been hospitalized. New cases are still being reported.
CDC and state public health officials are interviewing ill people to find out what they ate before they got sick. Farm Rich brand frozen food products is one likely source of the infections.
Certain Farm Rich brand frozen food products have been recalled. Check your freezer today for the recalled products and do not eat them. Throw away any recalled products you have at home.

If HUS develops, it usually occurs after about 1 week.
