Toxoplasmosis is an illness caused by the coccidian protozoan Toxoplasma gondii. Cats are the primary reservoir for T. gondii. T. gondii transmission in the United States is primarily foodborne, through handling or consumption of undercooked pork, lamb, or venison containing bradyzoites, the microscopic tissue cyst form of the parasite. People also can be infected through direct contact with cat feces that contains Toxoplasma oocysts or though consumption of food or water that has been contaminated with oocysts.
