INNOVATIVE PESTICIDE KIT MODEL FOR VEGETABLE FARM SAFETY SURVEILLANCE PROGRAM

Agricultural farming was reported in 2011 as main common sector of Thailand, representing 35.8% of labor force. Recognizing that contaminated pesticides in farm produce, especially the 4 groups; organophosphate, carbamate, pyrethroid and organochlorine were detected. Innovative pesticide kit model was developed in Thailand for vegetable farm safety surveillance. Collected vegetable in central market of Nakhonratchasima province, 5.6% detected samples of unsafe pesticide residues. A quasi study was performed during May 2012-October 2013 in Nakhonratchasima province. Study group; klongtabak village, ladbuakao subdistrict, sekhiew district and control group; ta-ngoy village in chanthuek subdistrict, pakchong district. Pesticide residues were highly detected in marketed Chinese kale vegetable by MOPH, Thailand in 2012, Chinese kale samples from plantations in both groups, were purposively collected. Validated 4 groups innovative pesticide test kit of Department of Medical Sciences, obtained petty patents from Thailand Intellectual Property Department, was used to screen pesticide residues in 62 collected kale samples. All kale samples were analyzed, using spectrophotometer for % acetyl cholinesterase inhibition assay, that enzyme was inhibited by organophosphate and carbamate, detected or suspected unsafe samples were quantitatively determined of pesticide residues (Codex’s MRL) using GLC/HPLC. Before intervention study, two detected samples of chlorpyrifos (>MRL) in control, two detected cypermethrin (>MRL) and one detected
