Toxoplasmosis is a zoonotic disease caused by Toxoplasma gondii. The definitive host of T. gondii is the cat, while the intermediate hosts are all mammals. Livestock become infected by ingesting sporulated oocysts in the environment, while humans can be infected by T. gondii due to environmental contamination by T. gondii oocysts, consumption of foods and milk containing cysts or tachyzoites of T. gondii. Raw milk is a risk factor for toxoplasmosis in humans. This paper discusses the presence of T. gondii in raw milk from various animals in both artificial and natural infections, the survival of T. gondii in milk and its derivatives and raw milk as a risk factor for toxoplasmosis in humans.
