Abstract
Pesticide residues in raw agricultural commodities pose major concerns in food safety. Rapid detection of pesticide residues can assist in consumer awareness and protection. Rapid bioassay for pesticide residues (RBPR) and rapid test kit (RTK) are rapid detection tools for the detection of organophosphate (OP) and carbamate (CM) pesticide residues based on enzyme inhibition and colorimetric reactions, respectively. Vegetables from different markets in Laguna, Quezon, Metro Manila, and Benguet were sampled and analyzed for the presence of OP and CM residues. Out of 112 samples of organic-labelled vegetables, 17 (15.18%) were positive to RBPR, compared to 7 (5.38%) out of 130 conventionally produced vegetables. RTK results were 27.8% and 37.5% positive for organic labelled and conventional vegetables, respectively. Bittergourd, eggplant, and tomato were frequently positive using RBPR and/or RTK tests. RBPR and RTK are complimentary rapid detection tools useful in monitoring compliance to principles of organic farming and market collected samples for immediate action. RBPR and RTK are limited to the detection of Ops and CMs, the group of pesticides which are toxic, cheap and commonly used by vegetable farmers.
