Abstract: QuEChERS is a quick, easy, cheap, effective, rugged and safe method for the analysis of multiple pesticide residues based on dispersive solid phase extraction. The approach involves the extraction of sample with acetonitrile or acetonitrile containing 1% (V/V) acetic acid, and simultaneous liquid-liquid partition by adding anhydrous magnesium sulfate and sodium chloride. The supernatant was provided with adsorbents such as PSA, C18, and GCB to remove matrix interference. Finally, the sample was analyzed by GC-MS or LC-MS/MS. In the field of veterinary drug residue analysis, QuEChERS was mainly applied to determine the residues of sulphonamides, quinolones and benzimidazoles in milk, tissues and livers of animal-derived foods. This paper will focus on the developments of QuEChERS in the field of veterinary drug residue analysis and provide a new idea and methodology to analyze veterinary drug residues.
