Ground Beef 1986

Cases of E. coli O157:H7 were detected throughout Washington state in November, 1986. The outbreak was detected after a physician in eastern Washington hospitalized three patients with hemorrhagic colitis which progressed to thrombotic thrombocytopenic purpura. Illnesses occurred among patrons of a specific restaurant, and nursing homes. It was suspected that ground beef was the vehicle. Tracing of the beef led to farms where cattle were shown to be carrying E.coli O157:H7. The E. coli O157: H7 strains that the cattle carried were different from the common strain that caused the human illnesses.
