An outbreak of cryptosporidiosis has been linked to a petting zoo in Minnesota, according to the Republican Eagle newspaper in Red Wing, Minn. Two people contracted the disease, which causes diarrhea, stomach cramps, and vomiting, among other symptoms. More than a dozen other people also fell ill after attending a one-day petting zoo held by the Humane Society of Goodhue County.
Proper hygiene is the number one way to prevent cryptospordidiosis infections. If you attend a petting zoo or other exhibit of live animals, make sure to wash your hands immediately afterward to avoid infection.
The National Association of State Public Health Veterinarians has a great, easy-to-understand resource on proper hygiene after visiting an animal exhibit. For more information on the causes and symptoms of cryptosporidiosis, the U.S. National Library of Medicine has a page on the disease.
