Which statement about preventing toxoplasmosis indicates a need for further instruction?

The statement indicating a need for further instruction is the one regarding drinking unpasteurized milk. It is important to avoid unpasteurized milk because it can be a source of various infections, including those that may be harmful during pregnancy. Pasteurized milk has undergone a heating process that kills harmful bacteria and parasites, making it safer to consume.

To reduce the risk of infections such as toxoplasmosis, pregnant individuals should adhere to safe food handling practices, which include consuming only pasteurized dairy products. The other statements reflect important preventive measures for avoiding toxoplasmosis, such as avoiding raw meat, washing fruits and vegetables, and practicing good hygiene after handling cat litter, all of which are crucial for minimizing risk to both the mother and the developing fetus.
