Abstract
Objective: To determine the contamination of organophosphate and carbamate in fresh-cut fruits sold by fruit vendors around a University in the lower Northern. Methods: The researchers collected 2 types of fresh-cut fruit samples, apple and guava, from 18 stores with a total of 36 samples. The 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. Results: The fresh-cut apple and guava had percentage of AChE inhibition at 31.00±4.72 and 25.84±4.01, respectively. The results showed no statistically significant differences between the average of percentage of AChE inhibition in both samples (P=0.42). However, percentage of enzyme inhibition in 4 samples of fresh-cut apple was at the unsafe toxicity levels (22.22 percent), while that in 2 samples of fresh-cut guava were found at unsafe toxicity levels (11.11 percent). Conclusion: The presence of pesticide residue in fresh-cut guava and apple is a problem potentially having a negative effect on health of consumers. Relevant agencies should monitor and test for pesticide residues in fresh-cut fruits for food safety.
