Public Health Implications of Pesticide Residues in Food: Risks, Regulations, and Interventions

Abstract

Pesticides enter food primarily through direct application to crops during farming, where residues can remain on the surface or be absorbed into plant tissues. Additionally, pesticide drift from nearby treated areas and contamination of soil or water used for irrigation can introduce residues into food crops, further increasing the risk of exposure. This paper focuses on the public health implications of pesticide residues in food. The paper found that pesticide residues in food pose significant public health challenges, with potential risks ranging from acute toxicity to chronic health issues such as cancer, endocrine disruption, and neurological disorders. Vulnerable populations, including children, pregnant women, and the elderly, are particularly at risk. Effective regulation and monitoring become crucial as the agricultural sector relies heavily on pesticides for crop protection. Regulatory bodies such as the World Health Organization (WHO), Food and Agriculture Organization of the United Nations (FAO), Environmental Protection Agency (EPA), and European Food Safety Authority (EFSA) play crucial roles in setting Maximum Residue Limits (MRLs) to ensure food safety. However, implementing these regulations faces obstacles, particularly in developing countries, where resource constraints, lack of technical expertise, and socio-economic factors impede effective monitoring. Integrating pest management (IPM), advanced monitoring techniques and consumer education are essential to mitigate the risks posed by pesticide residues. The global harmonization of pesticide standards and continued research into safer alternatives and residue detection methods are critical for ensuring a secure food supply. As agricultural practices evolve, a multi-stakeholder approach involving policymakers, farmers, and consumers will be vital in reducing pesticide exposure and safeguarding public health.
