A comprehensive analysis undertaken on date fruits from Kerman Province, Iran, revealed the presence of pesticide residues and assessed health risks associated with their consumption. The study, which considered 211 different pesticides, utilized the efficient QuEChERS method, coupled with advanced chromatography techniques like GC–MS–MS and LC–MS–MS.
Conducted between June and August 2023, the research sample comprised 90 date fruit samples sourced from various markets and shops. Amid increasing consumer health concerns surrounding pesticide residues, it was imperative to determine the extent of contamination and its potential effects.
The findings of the study indicated significant results: of the 90 analyzed samples, 10% contained at least one pesticide residue, and 5.5% exceeded the maximum residue limits (MRL) established by national and European standards. The researcher’s methodology encompassed probabilistic assessments via Monte Carlo simulations to estimate health risks associated with these residues.
The results of the risk assessment displayed no correlation between pesticide residues and carcinogenic risks, establishing the importance of rigorous monitoring to maintain food safety. The identified hazard quotient (HQ) and hazard index (HI) for both adults and children were reported to be lower than the threshold of 1, signifying acceptable risk levels. This aligns with the observation by the authors of the article, who emphasized, 'the HQ values of < 1 for all pesticide residues were in date fruit samples for adult and children consumers.'
Notably, among the pesticides most frequently detected were cypermethrin, imazalil, and bromopropylate, with the authors noting, 'the analysis showed... no carcinogenic risk to the consumers of date fruits.' This is significant reassurance for consumers who might be apprehensive about the safety of their food supply.
Current practices surrounding agricultural product safety require stringent monitoring and testing for pesticide residues. With these insights, Iranian policymakers can forge effective regulations on pesticide usage and safety practices to preserve consumer health.
The conclusions drawn from this study advocate for continuous and proactive surveillance of pesticide residues not just for date fruits, but for other agricultural products as well. Ensuring adherence to safety standards through effective regulatory frameworks will help mitigate risks associated with pesticide exposure.
