The major ways in which man acquires toxoplasmosis are through handling and consumption of raw meat and contact with feces (in litterpans and soil) from cats infected with Toxoplasma gondii. To prevent toxoplasmosis, certain steps should be taken. Meat should be heated throughout to 150 F (66 C) before consumption, and hands should be washed with soap and water after handling meat to remove any toxoplasma organisms contaminating the skin. Infection of indoor cats can be prevented by feeding them dry, canned, or boiled food and by restraining them from hunting. To the extent that diet cannot be controlled, an indoor eat's litterpan should be cleaned daily, feces should be flushed down the toilet, and the pan should be disinfected with boiling water. A person should wear disposable gloves while performing these tasks. Since soil contaminated by oocysts from T. gondii in feline feces is difficult to disinfect, contaminated sand in children's sandboxes should be disposed of, and gloves should be worn while one is working with soil that may contain feces from cats. Pregnant women should avoid cats whose source of food is unknown and should not empty litter pans, as toxoplasmosis can be transmitted to infants in utero.
