During July 2002, the Colorado Department of Public Health and Environment identified an outbreak of bloody diarrhea infections among Colorado residents that was linked to eating contaminated ground beef products produced by a commercial beef-packing plant. Initial investigation identified 28 cases of illness in Colorado and six other states. Seven patients were hospitalized; five developed hemolytic-uremic syndrome (HUS). The median age of patients was 15 years (range, 1-72 years). The dates of symptom onset ranged from 13 June to 7 July. Symptoms of the disease included bloody and nonbloody diarrhea, vomiting, and abdominal cramps. The illness typically resolved within 7 to 10 days. A subset of patients, particularly the young and elderly, developed HUS, characterized by hemolytic anemia (anemia resulting from lysis of erythrocytes), thrombocytopenia (a decrease in platelets that causes blood to fail to clot), and renal failure. Interviews with 16 patients with confirmed infections revealed that all had eaten ground beef during the 7 days before illness. Furthermore, in every case, the ground beef had been purchase at grocery chain A between 10 and 24 June. The pathogen was cultured from an opened package of ground beef collected from a patient's home. A trace back by the Colorado Department of Public Health and Environment of ground beef from a patient's home indicated that it was reground by grocery chain A with a meat produced on 31 May by a single commercial beef-packing plant. The extent to which the meat was repacked and distributed under other labels was unclear. Independent of the outbreak investigation, the beef-packing plant identified the pathogen during routine microbiologic testing conducted by the U.S. Department of Agriculture. Antigen tests were used to specifically identify the pathogenic nature of the isolation bacteria by testing for the types of H (flagellar) and O (lipopolysaccharide) antigens. The commercial beef-packing plat produced 18.6 million pounds of fresh and frozen ground beef and trimmings between 12 April and 11 July.
