Final answer:
The most common transmission of toxoplasmosis is through the ingestion of undercooked or contaminated meat. Toxoplasma gondii is usually contracted from domestic cats or contaminated food and water, and proper hygiene and cooking practices are advised to prevent infection.
Step-by-step explanation:
The most common transmission of toxoplasmosis infection is ingestion of undercooked meat. Toxoplasma gondii, the protozoan that causes toxoplasmosis, is found in a variety of birds and mammals. Humans typically contract toxoplasmosis by ingesting the parasite through undercooked or contaminated meat. The oocysts shed in the feces of infected cats can contaminate food or water and consequently be ingested by humans. The Centers for Disease Control and Prevention (CDC) advises that preventive measures, such as washing hands after handling raw meat and cooking meat to the proper internal temperature, are crucial to avoid infection.
