Abstract

For this study, we conducted a simultaneous multiresidue analysis of veterinary drugs in cultured fishery products in Chungnam Province in 2018. A total of 115 fishery product samples were obtained from fish farms and fishery production sites located in the province. In all, 29 residual veterinary drugs in the samples were analyzed using a validated liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. As a result, veterinary drug residues were only detected in a small number of the 106 samples (92.2%), and the detection rate was 7.8% (9 of 115 samples). The amounts were also below maximum residual limit (MRL) for fishery products, although one sample exceeded the MRL allowed by the Ministry of Food and Drug Safety and was detected in loach. The nine residual veterinary drugs were detected in 8 samples: loach, eel, catfish, freshwater bream, flatfish, rockfish and shrimp. The detected veterinary drugs were oxolinic acid, enrofloxacin, ciprofloxacin, sulfadiazine, flumequine and oxytetracycline. The most frequently detected antibiotic was oxolinic acid, and enrofloxacin exceeded the MRL in loach sample. Residues of most veterinary drugs were either not detected or were below the MRL, and while the status of fishery products is seen as safe overall, current surveillance efforts over veterinary drugs should be continued.

본 연구에서는 2018년 충남지역에서 생산, 출하되는 수산물에 대해 잔류동물용의약품 실태를 조사하였다. 수산물 115건을 대상으로 식품공전 수산물 중 동물용의약품 동시 다성분 시험법으로 분석이 가능한 29종의 잔류동물용의약품을 분석하였다. 115건의 수산물 중 9건에서 6종의 잔류동물용의약품이 검출되었으며, 검출률은 7.8%이었다. 검출된 잔류동물용의약품은 옥소린산, 엔로플록사신이 가장 많이 검출되었으며 시프로플록사신, 설파디아진, 플루메퀸, 옥시테트라사이클린이 각각 검출되었다. 미꾸라지 검체 1건에서 엔로플록사신이 잔류기준을 초과하였으나 전체적으로 안전한 수준으로 평가되었다. 그렇지만 잔류동물용의약품 검출률이 높아지는 추세이고 종류 또한 다양해지고 있어 지속적인 모니터링이 필요하다.
