E. coli, or Escherichia coli, is a type of bacterium that is naturally present in the intestines of humans and animals where it does not usually cause any problems. However, there are certain types (or strains) of Escherichia coli that can cause poisoning.Escherichia coli O157:H7 (or E. coli O157:H7) is one such strain, and it has been responsible for several E. coli outbreaks in the US, Canada, Spain, France, Germany, Japan and the UK since 1982.owever, there are certain types (or strains) of Escherichia coli that can cause poisoning.
