Explain how parasites contaminate food.

There are two ways that parasites are commonly transmitted to humans via food. (1) Some parasites are present in human fecal matter and so may contaminate drinking water, foods handled by infected persons, or vegetables and fruits grown on soils fertilized with infectious feces. (2) The infectious form of the parasite may develop in the tissues of a food animal, such as cattle, swine, or fish, and the infect humans who eat the meat.
