Abstract

This study aimed to determine the contamination of organophosphate and carbamate in fresh chilies sold by 5 stalls in a wholesale vegetable market and 3 supermarkets in Phitsanulok. A total of 24 various types of chilies, including Kii noo chili, Chinda chili and Chee fah chili, was collected. All samples were tested for residues of pesticides using GT-test kit with 60 minutes of time for analysis. The result was expressed as a percentage of acetylcholinesterase (AChE) inhibition. The Chinda chili had the highest percentage of AChE inhibition at 27.62±19.16 followed by Kii noo chili at 18.31±4.18 and Chee fah chili at 11.63±4.67. The results showed statistically significant differences between the average of percentage of AChE inhibition of diffrence types of chilies (F = 3.958, p = 0.040). All of the chili samples contained the average percentage of AChE inhibition at the safe toxicity level. However, the percentage of enzyme inhibition in one sample of Chinda chili was at the unsafe toxicity levels with the percentage of AChE inhibition of 89.47. The presence of pesticide residue in fresh chilies might have a negative effect on health of consumers. Relevant agencies should monitor and test for pesticide residues in fresh chilies for food safety.    Keywords:  chili, pesticides, enzyme inhibition assay
