In total, 348 serum samples were analyzed by the Immunofluorescence Assay (IFA) technique to detect IgG anti-T. gondii, considering a dilution of 1:64 as the cut-off point. Investigative questionnaires were used to analyze risk factors through objective questions, answered by the breeder, about the productive, reproductive and sanitary management characteristics of the property. Multivariate and univariate analysis were carried out, based on a logistical regression model, considering the serological status of the animal as the dependent variable (positive or negative) and the spatial distribution of foci. Of the 348 goat serum samples analyzed, 90 (25.86% C.I. 21.41% – 30.86%) were positive, with nine foci (60.00%). Of the ninety-positive samples, 21 (23.34%) exhibited titers of 64; 15 (16.67%) titers of 128; 17 (18.89%) titers of 256; 23 (25.55%) titers of 512 and 14 samples (15.55%) titers of 1024. In the analysis of the logistical regression, semi-intensive management was confirmed as a risk factor (OR 9.96; C.I. 2.30 - 43.14). In conclusion, there is an elevated number of foci of the infection in the region studied, which indicates the need to design animal health planning projects, to implement control and prophylactic measures, and to make the producers aware of animal health requirements and the risk that this infection can generate for the health of the general public.
