Abstract
Over the last decade, pesticide use in agriculture has helped protect crops but left residues in food, posing health risks. This study analyzed organochlorine (Delta-HCH and Beta-HCH) and organophosphate (chlorpyrifos and dimethoate) residues in lettuce and green pepper from two communities in Ghana. Thirty-one farmers were surveyed, and samples were tested using Gas Chromatography. Chlorpyrifos, found in lettuce from Legon farm at 0.1403–0.2291 mg/kg, exceeded EU and USA Maximum Residue Limits, while green pepper contained no residues. Findings emphasize the need for ongoing pesticide monitoring and public education to ensure food safety and health.
