How do people get Toxoplasmosis?
While cats are usually infected by preying on infected rodents (or more rarely by ingestion of oocysts from the environment), humans are most commonly infected through food. Sheep, cattle and pigs grazing on contaminated pastures, or fed oocyst-contaminated food, can also develop the encysted form of the organism in body tissues. If infected meat is not adequately cooked, or poor hygiene precautions are adopted during handling of uncooked meat, humans can become infected.
