Contamination of Pesticide Residuals among Fresh Consuming Vegetables from Market in Phuket Province

Abstract

This comparative quantitative research study was designed to detect organophosphate and carbamate pesticides residues in fresh-consumed vegetables in Phuket. A total of 405 fresh vegetable samples consisted of 225 samples normally fresh-consumed vegetables such as coriander, winged bean, lettuce, yardlong bean and spring onion and 180 samples of indigenous vegetables such as Gotu kola, Acacia, Cashew nut, Man pu (Glochidion wallichianum Mull. Arg.) and lettuce dove were purchased from 3 municipal markets and 3 supermarkets from 3 districts in Phuket. All samples were examined by MJPK test kit from the Department of Medical Science, the Ministry of Public Health.    

The result was detected unsafety level pesticides residues in normally fresh-consumed vegetables which is spring onion (1.77%), most unsafety level of pesticides residues was detected in indigenous vegetables which is Gotu kola (1.11%) in A and B municipal Market in 3.33% and 1.66 %, respectively. Pesticides residue safety level was detected in C district and supermarket (100%). The contamination of safety level and and unsafety level of organophosphate and carbamate pesticides residues in vegetables from municipal’ s markets and supermarkets were significantly different (p-value=0.01). It was not found in vegetables from supermarkets. This study showed the success of the food safety program in Phuket. However, relevant agencies should suggested people for decreasing pesticide residues methods by washing vegetables with fresh water, vegetable washing liquid and ozone water for sustainability of a healthy population.
