Food-borne and zoonotic-featured parasites in humans can cause infections and deaths. T. gondii infections are seen in almost every country depending on the community consuming various meat and meat products raw or undercooked. The current toxoplasmosis that presents in approximately one third of the world causes economic burden because of insufficiency effects of antibiotics and antiparasitics on the tissue cysts, retardation in treatment and increasing losses in labour force. Although numerous methods have been developed for protection from toxoplasmosis, there are still some difficulties in putting them into practise. A standardized serological test is not available to apply before slaughtering. The margin of error is higher in microscopic diagnoses from tissues after slaughtering due to the parasite distribution is not homogeneous and the results for determining infective parasites cannot be obtained from tests based on the PCR technique. For these reasons, the infections caused by tissue cysts localized in meat and organ of slaughtered animals such as sheep and goats have relatively high rates of seropositivity. The consumption of undercooked or raw meat containing cysts has been indicated as the main source of human toxoplasmosis. Although the heat treatment has been reported to be the most reliable method for inactivation of tissue cycts, freezing the meat has also been advised as an alternative treatment. The desired results were not obtained from the gamma rays or high-pressure technology because of the influence on meat texture.
