نبذة مختصرة : This study aimed to detect 11 carbamate pesticide residues in raw and pasteurized camel milk samples collected from the UAE using UHPLC-MSMS. A method was developed and validated by evaluating LOD, LOQ, linearity, extraction recovery, repeatability, intermediate precision, and matrix effect. A sample preparation step was needed due to the high content of proteins and fats in camel milk which may interfere with the analysis. For sample preparation, five different liquid liquid extraction techniques were tested for their efficiency in extracting carbamate pesticides from camel milk. The matrix effect was negligible due to the use of isotopically labeled internal standard. The detection limit of all studied carbamates was down to 0.01 𝜇g kg-1. A total of 17 camel milk samples were studied, and no carbamate residues were found in one sample only. The remaining 16 samples contained at least one carbamate residue, but the detected concentration for all residues was below the Codex-recommended MRL (< 10 𝜇g kg-1). However, the detected levels of ethiofencarb residue in three samples were on the borderline. The health risk of carbofuran, carbaryl, and propoxur was assessed for camel milk consumers by calculating HI values. The HI values of the three carbamate pesticides are less than one; thus, camel milk consumers are not at 39 risk.
