2009 Outbreak of E. coli O157:H7 at Western National Stock Show Petting Zoo, Colorado

An outbreak of E. coli O157:H7 probably originated in the "Feed the Animals" exhibit at the Western National Stock Show in Denver. Four specimens from floor sweepings and the mats on which animals stood in the "Feed the Animals" area tested positive for the identical strain of E. coli O157:H7 that had been found in the ill persons. The outbreak was never linked to a specific animal or farm.
