Prospective or expectant mothers can be serologically tested to determine if they are at risk for toxoplasmosis. Pregnant women who have cats as house pets may increase their risk of developing toxoplasmosis.

They should avoid contact with any materials that are potentially infected with cat feces or that could be contaminated by insects exposed to cat feces (cockroaches, flies, etc.). Meat should be cooked until well done, and the hands should be washed after handling raw meat.
