This application note describes an analytical method for the determination of 27 pesticide residues in olives. Olives have a high lipid content of about 80 to 85%, which can adversely affect pesticide recoveries and chromatographic systems. Therefore, a modified QuEChERS method for the extraction and analysis by gas chromatography/triple quadrupole (GC/MS/MS) multiple reaction monitoring method was employed. The method was validated for olives in terms of recovery, repeatability, and reproducibility. The results demonstrated that the method achieved acceptable quantitative recoveries of 70 to 120%, as recommended in SANCO/12571 , with RSDs < 20%. Limits of quantification at or below the regulatory maximum residue limits for the pesticides were achieved.
