Benzimidazole is an widely used anthelmintics in livestock clinics. The aim of present study was to investigate benzimidazole residues in the meat in Sejong City. A total of 338 samples of meat(beef 287, pork 37, chicken 14) were selected from the laboratory meat(Korean beef genetic test, hygiene test) supplied to school in Sejong City. Representative benzimidazole class drug such as thiabendazole, 2-amino albendazole sulfone, fenbendazole, oxfendazole, and oxfendazole sulfone were monitored in samples by using lc-ms/ms and the analysis was preformed based on the Korea Food Code guideline. Limit of quantitation (LOQ) was ranged from 0.56 to 3.02 ppb for target drugs and the accuracy was within the acceptance criteria. Among the sample analyzed only one case, the pork meat was found to have drug levels that exceed LOQ. However, the overall residue concentration was 2.17 ppb, which was lower than the maximum residue levels (100 ppb).
