Food safety problems caused by pesticide residues especially in date palm fruits have become one of the most important issues that threaten human health regarding that some farmers are not looking to the optimal use of these pesticides. In the present study, Evaluation of initial residues of different pesticides (Chlorpyrifos, Fipronil, Methomyl, and Carbendazim) varied from (0.34-3.11 mg/kg) above MRLs reflecting improper use. In order to deal that, recent technologies where utilized to reduce residues. Barhee cv date palm samples were subjected to two recent decontamination methods (Ozone and60CO γ-Radiation). The remaining residues were analyzed by GC-MS/MS and LC-MS/MS using validated QuEChERS methodology. The results showed that removal of pesticides (89.6%-97.3%) using 1.0 KGy60CO, γ-Radiation was effectively reduced chlorpyrifos residues to lower than MRLs while ozone method at 60 min reduced carbendazim residues (89.7%-96.8%) below its MRLs. Both technologies were able to decrease the residues for other pesticides and decrease the risk.
