The aim of this study was to determine the prevalence and to identify the risk factors associated with T. gondii infection in pregnant individuals living in the Ponta de Pedras municipality, Marajó Archipelago, State of Pará, where an outbreak of toxoplasmosis occurred in 2013. From 2014 to March 2017, a cross-sectional study was conducted, including 555 pregnant individuals aged 13- to 42-years-old. Serological tests (enzyme immunoassays) were performed, and socioenvironmental and behavioral information were obtained through the application of a questionnaire. A prevalence of 68.3% was detected, and older age, having contact with soil and living in an urban area were the risk factors associated with seropositivity. The study confirmed the high prevalence of infection among pregnant individuals in the region. The association of the infection with the variables of residential area and contact with soil indicates that there was environmental contamination by T. gondii oocysts in the municipality.
