The aim of this study was to evaluate the occurrence of anti-Toxoplasma gondii antibodies in female bovines in reproductive age (above 24 months of age) of the State of Goiás, Brazil and the risk factors associated with its presence. Indirect Immunofluorescence Reaction was used in samples of 2,970 cows from 263 farms, distributed in 223 municipalities. Epidemiological questionnaire was used to evaluate the risk factors. Results showed an average seroprevalence of T. gondii of 8.48% in cows of the State of Goiás and the microregions with higher chances (P≤0.05) of having infected animals were from Vão do Paranã, Anicuns, Chapada dos Veadeiros, Entorno do Distrito Federal, São Miguel do Araguaia, Ceres and Anápolis. Acquisition of females or males regarding reproductive purpose had a significant association (P≤0.05) with the occurrence of T. gondii in these regions, and there was also a positive correlation (correlation 0.7618; p = 0.047) amid the prevalence of T. gondii and the total area (in hectares) of forests present in these regions previously mentioned. These results highlight the importance of the meat from these animals being considered as an important route of infection for humans who eat this raw or undercooked food.
