RESUMO

Abstract Food quality and safety have been a concern of the world population, especially in relation to the chemical and microbiological hazards present in food. The presence of antimicrobial residues at levels above the maximum residue limit makes milk unsuitable for human consumption. In this context, the objective of this study was to analyze 184 raw milk samples from the dairy region of Pernambuco state, in order to evaluate the presence of 31 antimicrobial residues from six different groups (β-lactam, sulfonamide, tetracycline, quinolone, fluoroquinolone and pyrimidine). The samples were collected from producers who supply the dairys with and no inspection service and the analyses were performed by liquid chromatography coupled to mass spectrometry. In the qualitative analysis of multiresidues, no sample presented violation for the antimicrobials analyzed. In the quantitative analysis of β-lactams, only one sample of producers who supply milk to dairys with state inspection service presented a result above the maximum residue limit for cloxacillin (464 μg.L-1). It is concluded that raw milk produced in the dairy region of the state of Pernambuco has a low rate of violation of the values established by the current legislation for antimicrobial residues.
