AB  - A modified QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) method was 
      developed for the simultaneous determination of veterinary drugs, pesticides and 
      mycotoxins in eggs by ultrahigh-pressure liquid chromatography-tandem mass 
      spectrometry (UPLC-MS/MS). Several extraction conditions were tested and 
      optimized, and the obtained extraction efficiency of all the targeted compounds 
      (particularly macrolides) could fulfill the requirements. In the purification 
      procedure, magnetic multiwalled carbon nanotubes (Fe(3)O(4)-MWCNTs) were used as 
      adsorbents, and an external magnet was utilized to achieve a faster adsorbent 
      separation, compared to the traditional centrifugation process. The recoveries of 
      all analytes were in the range of 60.5%-114.6% at three fortified levels with 
      relative standard deviations (RSDs) of less than 20%, and the LOQs ranged from 
      0.1 mug.kg(-1) to 17.3 mug.kg(-1). This method was successfully applied to the 
      analysis of egg samples, demonstrating its applicability and suitability for the 
      routine analysis of multiclass residues in egg samples.
