E. coli Infection


About this topic


E. coli is one more name for Escherichia coli. Sometimes, doctors will put numbers after the words E. coli to help point out which kind it is. This germ makes toxins in your small bowel. The toxins cause very bad loose stools. The toxins may also break the lining of the bowel and cause bleeding in the bowels. ‚  
You get this germ most often by eating or drinking contaminated food or water. It is also easy to pass this germ from person to person. People may become infected through: ‚  
  • Eating raw or undercooked foods, such as cookie dough, fresh picked produce that has not been washed, unprocessed or undercooked meat such as sausage, or food from a street vendor
  • Drinking fresh or raw milk that has not been treated
  • Germs spread from other people. This is often due to poor hand washing after going to the bathroom.
