Toxoplasma gondii is an important foodborne pathogen worldwide, with undercooked meat as the main source of human transmission. In this study, we determined the seroprevalence of T. gondii in free-range pigs from two adjacent villages in the Tumbes region of northern Peru, El Tutumo and Nuevo Progreso. We randomly selected 100 pig serum samples collected during a prior study and processed these using Western Blot to detect IgG anti-T. gondii antibodies. Results indicated a prevalence of 32% (32/100) to T. gondii in pigs. Free-ranging pigs from northern Peru represent a substantial risk for transmission of T. gondii to humans.
