The purpose of this study was to investigate pesticide residues in fruits from the Egyptian Markets. A total of 18 samples of fresh fruits samples collected from Egyptian markets during November to December 2019. Selection of fresh fruits based on their popularity and consumption at all socioeconomic levels during the winter season. Samples were subjected to pesticide residues analysis using multi residues standard method (QuEChERs). The determination of residues carried out using GC-MS/MS and LC-MS/MS. The samples were analyzed using an accredited method that is capable of quantify 450 pesticide residues from different pesticide groups. Thirty-one pesticides were detected in all analyzed samples. All samples had detectable pesticide residues. Whereas, 100% (18 samples) had detectable pesticide residues of which contaminated at 55.55% level above the MRLs and 44.44% (8 samples) had residues below the MRLs. Whereas, all samples were contaminated with tomato, orange and guava (100% respectively) with 16.66%, 83.33% and 66.66% exceeded the MRLs, respectively. The hazard index (HI %), representing the long–term risk assessment was in the range of 0.135692%–1.978846% in tomato samples, 0.019972%–8.737660% in guava samples ,0.415385%–49.326923% in orange samples and 0.415385%–49.326923% in orange samples of the ADI's. The highest exposure was observed for carbendazim in tomato samples, omethoate in guava samples, dimethoate in orange samples of ADI respectively. The contribution to the ADI shows that all the intakes of pesticide residues in fruit samples are still within acceptable limits, as HRI % value less than 100% is considered as safe for human health.
