With the objective of monitoring toxic compounds residues in food, the frequency and levels of organochlorine pesticides and polychlorinated biphenyls were verified in sausage samples, hot dog type, commercialized in the city of Santa Maria (RS), Brazil. Values were compared with the ones established by Brazilian legislation. For the analyses the extraction of fat from the samples was done. From the purification of the fat, there was acquisition of an extract in which was determined the organochlorine contaminants residues by gas chromatography with electronic capture detector (CG - µECD63Ni). It was learned that the lindane and HCB were the pesticides that presented the biggest concentration averages (0.001798ppm and 0.001652ppm, respectively). The detected sum of organochlorine pesticides average levels was 0.015783ppm; and from this sum 0.011165ppm belonged to DDT metabolites. The largest average concentration of polychlorinated biphenyls corresponded to the PCBs 10 (0.001817ppm) and 28 (0.002172ppm). Concentrations of organochlorine pesticides and PCBs found in the samples were below the maximum allowed by legislation.
