All HIV-infected persons, including those who lack IgG antibody to Toxoplasma, should be counseled regarding sources of toxoplasmic infection. They should be advised not to eat raw or undercooked meat, including undercooked lamb, beef, pork, or venison (BIII). Specifically, lamb, beef, and pork should be cooked to an internal temperature of 165 °F–170 °F (44 - 45); meat cooked until it is no longer pink inside usually has an internal temperature of 165 °F–170 °F and therefore, from a more practical perspective, satisfies this requirement. HIV-infected persons should wash their hands after contact with raw meat and after gardening or other contact with soil; in addition, they should wash fruits and vegetables well before eating them raw (BIII). If the patient owns a cat, the litter box should be changed daily, preferably by an HIV-negative, nonpregnant person; alternatively, patients should wash their hands thoroughly after changing the litter box (BIII). Patients should be encouraged to keep their cats inside and not to adopt or handle stray cats (BIII). Cats should be fed only canned or dried commercial food or well-cooked table food, not raw or undercooked meats (BIII). Patients need not be advised to part with their cats or to have their cats tested for toxoplasmosis (EII).
