Introduction: Toxoplasmosis, caused by the protozoan Toxoplasma gondii, causes a retinal infection, affecting healthy and immunocompromised people in many countries. The parasite is transmitted through raw meat containing T. gondii cysts or water containing oocysts from feline feces. Both waterborne and food-borne outbreaks of the disease have been reported from countries with diverse cultural, social and ethnic backgrounds. The parasite can be transmitted vertically and if the woman acquires primary disease during pregnancy, it may be passed through the placenta to the fetus, resulting in congenital toxoplasmosis, which is a cause of mortality and malformation. Asymptomatic infants may develop abnormalities later in life. Although rare, the disease can also be transmitted through transplanted organs.
