The liquid chromatography tandem-mass spectrometry (LC–MS/MS) with ESI was applied for the detection of 55 pesticide residues in vegetables, extracted with QuEChERS. The average recoveries for all analites were 79.4-119.8% (RSDs 3.71-17.42%). The LC-MS/MS was used for the simultaneous residue determination of 55 pesticides in the vegetables. The validated method which uses the LC-MS/MS provides a very high sensitivity, good reproducibility, appropriate linearity and can be applied with the high reliability to the analysis of investigated pesticide residues in vegetable samples. The LOQs of 0.01 mg/kg confirm that the method is appropriate for the determination of pesticide residues in all investigated vegetables according to the regulations of the Serbian and EU MRLs. The multiple detections were confirmed in eight analysed samples. The most frequently detected pesticides were acetamiprid, metalaxyl-M and pyriproxyfen. In only one watermelon sample the concentrations of carbendazim (0....134 mg/kg) and tefluthrin (0.304 mg/kg) were above the MRLs, but all the other detections were below the MRLs.
