Officials with two separate health departments are investigating possible cases of Salmonella among people who attended the Arapahoe County Fair, or 4-H events associated with the fair, from July 21 to July 29.

The source of the Salmonella, which causes an intestinal infection, has not been identified and the Tri-County Health Department is searching for the origin.

The investigation began Aug. 3 and seven cases of Salmonella have been identified so far.

“If you went to the Arapahoe County Fair or attended a 4-H event associated with the Fair and have these symptoms, we encourage you to see your health care provider,” said the Executive Director of Tri-County Health Department. “While symptoms usually resolve on their own, your health care provider can advise on whether you need additional treatment.”
