Pesticide Residues in Raisin and Health Risk Assessment

This study aimed to determine pesticide residues in raisin samples from the Besni and Gölbaşı districts of Adıyaman province, located in the Southeastern Anatolia region of Türkiye. Method validation was carried out for parameters including linearity, limit of detection (LOD), limit of quantification (LOQ), recovery, precision (repeatability and in-laboratory reproducibility), and measurement uncertainty. The results met the criteria outlined in SANTE/11312/2021. A total of 260 pesticides were analyzed, with pesticide residues detected in 95 out of 100 samples. Among these, 42 samples contained a single pesticide, while 53 samples had two or more residues. The insecticides cypermethrin, indoxacarb, and malathion, along with the fungicides boscalid, flubendiamide, fluopyram, pyrimethanil, and spiroxamine, were identified. All detected pesticide residues were within the LOQ and maximum residue limit (MRL), with no residues exceeding the MRL. According to the analysis, eight different pesticides were identified in the samples. The study confirms that pesticide residues in dried grape samples comply with the MRLs, suggesting minimal health risks for consumers, as both long-term and short-term dietary risks were found to be negligible. However, the presence of multiple pesticide residues underscores the need for ongoing monitoring and stringent regulatory measures to ensure food safety and maintain compliance. These findings provide valuable insights into improving sustainable agricultural practices in grape production and establishing a more effective monitoring system for pesticide residues in raisins
