Pesticide residues in apple cultivation have become a significant concern in Morocco due to potential health risks for consumers. Despite regulatory measures, limited studies have assessed pesticide contamination levels in apples from the Fez-Meknes region. This study evaluated pesticide residues in apples collected from local markets and farms using the QuEChERS extraction method and HPLC-MS/MS analysis. A total of 31 apple samples were analyzed and risk assessment was conducted based on consumer intake data. 22 pesticides were detected, including seven banned compounds. The most frequently found residues were carbendazim (81%) and indoxacarb (68%). Several pesticides exceeded regulatory limits, with dimethoate reaching a chronic hazard index (HI) of 24.9, indicating significant health concerns. The method validation showed high accuracy, precision (RSD: 1-15%), and sensitivity (LOD: 0.0001-0.0007 mg/kg). A consumer survey revealed that 83.9% of participants regularly consumed apples, with 43.6% eating them unpeeled, increasing dietary exposure risk. These findings highlight widespread pesticide contamination in apples and potential health risks, particularly from dimethoate, carbendazim, and methomyl. Regulatory agencies should enhance pesticide monitoring, enforce stricter MRLs, and promote safer pest management practices.
