The contamination of stored food products by pesticide residues has become a major concern due to its potential health risks and environmental implications. Pesticides, widely used for pest control in agriculture and storage facilities, can leave residues that persist in food products, leading to human exposure through consumption. This study investigates the presence and concentration of pesticide residues in stored beans using High-Performance Liquid Chromatography (HPLC) analysis, focusing on two commonly used pesticides—dichlorvos and cypermethrin. These pesticides are frequently applied to stored grains to protect against insect infestation, but their residues may pose significant risks if present in excessive amounts. In this research, samples of stored beans were collected from multiple storage facilities to assess pesticide contamination levels. The HPLC method was optimized for high sensitivity and precision, ensuring accurate detection and quantification of dichlorvos and cypermethrin residues. The analysis revealed varying concentrations of pesticide residues across different samples, with some exceeding the maximum residue limits (MRLs) established by regulatory authorities. These findings highlight the potential risks associated with consuming contaminated beans, particularly concerning chronic exposure to pesticide residues, which has been linked to adverse health effects such as neurological disorders, endocrine disruption, and carcinogenicity. The study also explores the regulatory framework governing pesticide residue levels in food products, emphasizing the necessity of strict compliance with food safety guidelines. The findings underscore the importance of regular monitoring and enforcement of pesticide regulations to prevent excessive contamination of food commodities. Additionally, the study discusses the impact of storage conditions on pesticide persistence, noting that factors such as temperature, humidity, and storage duration can influence residue degradation or accumulation. Given the health risks associated with pesticide residues, this research advocates for the adoption of safer and more sustainable pest control strategies in food storage. Integrated pest management (IPM) approaches, including biological control methods, improved storage techniques, and reduced chemical dependency, should be prioritized to minimize the presence of harmful in food products. The study also suggests the need for further research into alternative storage practices that effectively preserve food quality while ensuring consumer safety. In conclusion, the detection of dichlorvos and cypermethrin residues in stored beans raises significant food safety concerns. The results of this study emphasize the urgent need for improved monitoring, stricter regulation, and the promotion of alternative pest control methods to ensure the safety and sustainability of food storage systems. By implementing proactive measures, policymakers, regulatory agencies, and stakeholders in the agricultural sector can contribute to minimizing pesticide contamination and safeguarding public health.
