TABLE 13

Measures for Primary Prevention of T gondii Infection in Seronegative Pregnant Women, According to the PAMF-TSL Experience and CDC Recommendations61

TransmissionRecommendations/Considerations
Meat and other edibles• Meat should be cooked up to at least 63°C (145°F) for whole cut meat (excluding poultry), up to at least 71°C (160°F) for ground meat (excluding poultry), and up to at least 74°C (165°F) for all poultry (whole cuts and ground) (a food thermometer should be used)
• Meat should be frozen at –20°C (–4°F) for at least 48 hours
• Freezing and thawing at specific temperatures for specific time can kill T gondii tissue cysts
• Infected meat that has been smoked, cured in brine, or dried may still be infectious
• Contact with mucous membranes should be avoided when handling raw meat
• Gloves should be worn when handling raw meat and hands should be thoroughly washed after handling raw meat
• Kitchen surfaces and utensils should be thoroughly washed after contact with raw meat
• Drinking unpasteurized goat milk should be avoided
• Eating raw oysters, clams, or mussels should be avoided
• Skinning or butchering animals without gloves should be avoided
Untreated water• Drinking untreated water, including that from wells, or water with potential contamination by feces from domestic or wild cats should be avoided
Cat feces and soil• Contact with material/soil potentially contaminated with cat feces, especially handling of cat litters or gardening, should be avoided. However, if not possible to be avoided, disposable gloves should be worn when gardening and during any contact with soil or sand and hands should be washed with soap and warm water afterward.
• Cats should be kept indoors. Stray cats should not be handled or adopted while the woman is pregnant.
• Cat litter box should be changed daily, because T gondii does not become infectious until 1 to 5 days after it is shed in a cat’s feces.
• Cats should be fed canned or dried commercial food, not raw or undercooked meats.
