A parasite is an organism that lives on or in a host organism and gets its food from or at the expense of its host there are three main classes of parasites that can cause disease in humans: protozoa, helminths, and ectoparasites protozoa are microscopic, one-celled organisms that can be free. The protozoan drugs can be given in starter and grower feeds for turkeys the incidence of the disease can be minimized by growing turkeys on wire and indoors the caecal worms should be eliminated and strict hygiene should be maintained. The protozoan parasites cryptosporidium, giardia, and cyclospora have proven potential to cause waterborne and foodborne illness or disease toxoplasma gondii has been considered a risk in specific cases, but humans are not its primary host.
