Toxoplasmosis is a worldwide parasitic zoonosis caused by Toxoplasma gondii. Pigs can become infected by consuming water or food contaminated with sporulated oocysts, or by carnivorism (like the consumption of infected rodents). In pigs most infections are asymptomatic. In certain countries, pig meat containing tissue cysts is a major source of infection for human beings. The aims of this study were to estimate the seroprevalence of toxoplasmosis and to identify which factors were related with the increase of the risk of infection in Argentina. The seroprevalence of T. gondii was determined in 240 pigs from 27 farms in the central-western area of Buenos Aires province, Argentina. Serum samples were analyzed using indirect fluorescent antibody test (IFAT) and enzyme-linked immunosorbent assay (ELISA) techniques. Prevalence determined was 53.33% and 32.08% by IFAT and ELISA, respectively. Results showed that 81.5% (22/27) of the farms were seropositive to T. gondii. Seropositivity for T. gondii was related with the following risk factors (p value ≤0.05): presence of felids and rodents in the farms, feeding with waste of human food and storage of food outdoors with free access to felids and to the reservoirs when applying both serological techniques. Our results strongly suggest that the risk of infection with T. gondii in pigs is related to the outdoor/extensive type of production system with low infrastructure conditions, which allows both felids and rodents to have free access to pigs and stored food. Also, the high seroprevalence detected in the present study could indicate a potential role of pork in human infections in the region.
