An outbreak of Cryptosporidiosis was associated with attending a petting zoo on March 31. The Humane Society of Goodhue County held a one day petting zoo and photo shoot at it shelter on Bench Street, Red Wing, Minnesota.

Illness histories and exposure information were obtained from 88 event attendees. Thirty-one cases were identified, including 5 who tested positive for Cryptosporidium parvum. Several people sought medical care but no one was hospitalized and no one died.

At the time of the investigation, the goat, lamb, and calf had been returned to their original owners and/or sold. A calf was reported by multiple attendees as having obvious signs of diarrhea. This calf had been sold to a farm in Wisconsin. The farmer was contacted and asked to provide a stool sample. A sample was never submitted for testing.

Stool samples from a goat, two dogs and a cat were negative for Cryptosporidium.
