coli bacteria was traced to six animals - two goats, two sheep, and two cows - used by Ag-Venture Farm Shows, the company that supplied the animals at all three fairs. The outbreak put fear into parents' hearts, caused a number of schools to cancel field trips to petting zoos, and prompted health officials to scrutinize barnyard exhibits more carefully. But instead of shutting these exhibits down, health officials simply warned people to wash their hands after petting the animals, use hand sanitizer, and/or wear plastic gloves.
