Potential sources of Toxoplasma gondii infection, as a foodborne zoonotic disease, and suggested control strategies, were investigated. Samples of fresh buffalo meat (FBM) and imported frozen buffalo meat (IFBM), raw vegetables (RVs) and irrigation water (IW) were examined for the presence of T. gondii infective stages. Serum samples from housewives, regarding their gloves usage, were serologically inspected for T. gondii antibodies. The prevalence of T. gondii tissue cysts in FBM and IFBM were 15.4 and 0%, respectively. FBM had an increased risk of 18.60 times than IFBM. The prevalence of T. gondii tissue cysts in RV and IW were 13 and 16.7%, with 0.78 times increased relative risk, respectively. The total antibodies were significantly differed between nonglove users and glove users, with seropositivities of 31 and 10.3%, respectively. Soaking of RV in water at 65C or in vinegar solution at 45C for 1 min was an effective treatment for complete elimination of the contaminant T. gondii oocysts.
