Cryptosporidium (crip-toe-spor-ID-ee-um) is a protozoan, a single-celled parasite that lives in the intestines of animals and people.
Abstract. The protozoan parasite Cryptosporidium, which is chlorine-resistant, is generally considered to be a waterborne pathogen, but foodborne transmission also occurs and has caused outbreaks of the gastrointestinal illness cryptosporidiosis.lthough usually considered to be transmitted directly person or animal to person or by contaminated water, food is a potential vehicle of transmission of Cryptosporidium to humans following contamination during production, harvesting, transport, processing, or preparation.
