Colorado health officials say a Denver-area E. coli outbreak in January and February was likely caused by exposure to animals at the National Western Stock Show in Denver.
A report Friday from the Colorado Department of Public Health and Environment says the outbreak probably originated in a "Feed the Animals" exhibit in the children's area. Investigators weren't able to pinpoint the exact animal that may have caused the outbreak.
Thirty E. coli cases were identified in the outbreak. Of those, nine people were hospitalized.
Stock show President and CEO Pat Grant says there will now be signs warning of potential risks at stock and agricultural shows and of the need to wash hands and observe proper hygiene.
