A water-borne parasite has sickened ten kids after they played in a fountain at the Minnesota Zoo. The Minnesota Department of Health says the children contracted cryptosporidiosis, a disease passed through oral contact with human or animal feces. It's the first recorded outbreak in a public recreation area. But as Minnesota Public Radio's Lorna Benson reports, state health officials fear more outbreaks could occur as the number of water slides, fountains and wading pools increase.
