The toxo parasite rarely affects a healthy adult person (if it does, seek medical attention), but it can have devastating effects on
a fetus. The parasite can cause eye
inflammation leading to blindness, and calcium deposits in the brain, leading to mental retardation. The parasite can also cause spontaneous abortions.This is why you should always wash your hands, the surface of counters, utensils and other cooking implements if in contact with meat.
