A range of pesticides are applied to crops to control pests and diseases but there are concerns about the persistence of residues in food and processed food products. The quick, easy, cheap, effective, rugged and safe (QuEChERS) method has generally been used for the determination of pesticide residues in different food commodities. QuEChERS principle and the extracts were cleaned up through dispersive solid-phase extraction with primary and secondary amine after salting out with NaCl and MgSO4. This sample preparation approach has emerged as a versatile alternative method for analyte extraction and this technique requires little organic solvent and can also improve the limits of detection. QuEChERS is of increasing interest in the analysis of pesticide residues and is applied in the determination of various classes of pesticides in food commodities.
