Objective To establish a rapid detection method for the simultaneous determination of 24 kinds of veterinary drug residues in pork by QuEChERS technique combined with ultra performance liquid chromatography-tandem triple quadrupole mass spectrometry (UPLC-MS/MS). Methods The samples were extracted with acidified acetonitrile, salted out by 3 g magnesium sulfate anhydrous and 2 g C18 E, separated by Thermo-Fisher Hypersil GOLD aQ chromatographic column (50 mm×2.1 mm, 1.9 μm) via gradient elution of acetonitrile and 0.1% formic acid aqueous solution. The gradient elution of acetonitrile and 0.1% formic acid in aqueous solution was performed in the mode of electrospray positive ion scanning. Results The linear relationship of 24 kinds of veterinary drugs was good, and the correlation coefficients were greater than 0.9910, and the detection limit ranged from 0.2-10.0 μg/kg. The spiked recoveries varied between 70.2%-110.3%, and the relative standard deviations were 1.2%-13.8%. Conclusion The method is simple, rapid, accurate, practical, and suitable for detection of multiple veterinary drug residues in pork.
