The objective of this study was to determine the frequency of Brucella sp in pigs from well managed and poor managed farms ot the Lima valley, Peru. For this purpose, blood samples of pigs from well managed (n = 222) and poor managed (n = 218) forms were collected at two slanghterhouses. Animals were of both sexes and older than 4 months of age. Antibodies against Brucella sp. were detected by the Rose Bengal test (RB) and Complement Fixation (CF) test. The frecuency of Brucella sp. was 4.77 ± 1.81% in the studied population. The frequency of Brucella sp. in well and poor managed pig farms were 2.25 ± 1.47% (5/222) and 7.34 ± 3.34% (16/218) respectively, when RB test was used. However, only 2.75 + 1.76% (6/218) in poor managed farms had antibodies against Brucella sp when using the CF test. None of the animals from well managed farms resulted positive by CF test. This study indicate the presence of brucellosis in poor managed pigs farms, representing a risk for the pig industry and public health.
