The objective of this work to study the occurrence of anti-Toxoplasma gondii (T. gondii) and Leptospira spp. in pig killed in the Micro Valley Ipojuca Wasteland of Pernambuco We collected blood samples from 305 animals from 11 municipalities. Sera were submitted to the Immunofluorescence Assay (IFA) for detection of anti-T. gondii, by adopting a cutoff of 1:64. In animals positive for IFA was used the PCR technique to detect the DNA of T. gondii in fragments of heart. To search for anti Leptospira spp. used the microscopic agglutination test (MAT). Among all samples, we observed that thirty-eight 38/305 (12.46%) were positive for anti-T. gondii and 267/305 (87.54%) were negative, distributed in 11 cities. Of the animals positive serology, 21/38 (55.26%) were also positive in PCR. Results related to Leptospira spp. showed that 78/305 (25.57%) positive samples and 227/305 (74.42%) negative, distributed in 11 municipalities. The most frequent serovars were Icterohaemorrhagiae, Copenhageni, Djasiman and with frequencies of 55.12%, 17.94% and 6.41% respectively. It was concluded that pigs were beaten in the region exposed to infection by these agents and raises a discussion about the health risks of food handlers and consumers of carcasses and the need to minimize them through the implementation of surveillance programs and corrective actions in region studied.
