Objective: As consumption of chicken meat may be as one of the sources of human infection, this study was undertaken to determine the prevalence of T. gondii among the free Range Chicken , by using ELISA in Tabriz, Northwest of Iran.
Materials and Methods: One hundred blood samples were collected from free Range chickens by a cluster random sampling method and tested for toxoplasmosis by Enzyme Linked Immunosorbant Assay (ELISA). The results were analyzed by SPSS software using Chi-Square test and a P value <0.05 was considered statically significant.
Results: Results revealed ,that 18% of Free-Ranging chickens positive by ELISA respectively. Although the difference observed in the percentage of T. gondii antibodies among different areas of Tabriz city, Iran, there was no significant differences P < 0.05 detected by the ELISA method.
Conclusion: Based on cultural and food habits in our area, the meat and viscera of chicken may be important sources of infection in human when consuming semi-cooked meats. Considering the high prevalence of toxoplasmosis in chickens, standards in chicken breeding, education of environmental health personnel and standardization for preparation and handling techniques are required by Health and Veterinary organizations.
