E-mail: [e-mail] This study aimed to determine the frequency of pigs seropositive to Toxoplasma gondii by indirect immunofluorescence assay with cutoff 1:16. Of blood samples collected at slaughter, 250 of them were from animals raised in the State of Minas Gerais; while 181 were from the State of Rio de Janeiro with a total of 431 examined samples. Of these, 19/250 (4.41%) of MG and 39/181 (9.04%) of RJ, determining a total of 13.45% seropositive animals. Regardless of slaughter be under the control of the inspection service, the precedence of the animals was highly significant (p = 0.0001) in the number of seropositive animals. Although the percentage of seropositive animals to T. gondii from both regions studied in this work, and from the point of view of a public health problem, pork and its frescal type products may continue to be considered as a source of infection of this coccidia for humans, if they are consumed as raw or undercooked.
