This study aimed to determine the contamination of carbamate pesticides in Japanese melons, and to investigate health risk assessment from Japanese melons consumption. A total of 9 Japanese melons from 3 melon farms in Phitsanulok was collected and tested for 11 carbamate pesticide residues using QuEChERS (quick, easy cheap, effective rugged and safe) technique with HPLC-QTOF-MS (high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry). The highest detected carbamate pesticide residue in Japanese melon samples was carbaryl (0.574±0.020 mg/kg), followed by aldicarb sulfoxide (0.310±0.622 mg/kg). Carbamate residues detected in Japanese melons did not exceed the standard of agricultural products of Thailand. The hazard quotient (HQ) of carbamate pesticides had a range of acceptable risk in which the highest HQ was aldicarb sulfoxide (HQ = 0.268), and the lowest HQ was methomyl (HQ = 0.007). Therefore, relevant agencies should monitor and determine other pesticide residues in Japanese melons for food safety.
