市售水產品中動物用藥孔雀綠及其代謝物殘留量調查

Survey on Malachite Green and Leucomalachite Green Residues in Marketed Aquatic Products

97年度市售水產品檢體委由各縣市（政府）衛生局進行採樣，包括虱目魚12件、吳郭魚10件、鱸魚8件、石斑魚6件、甲魚5件、鰻魚4件、午仔魚3件、魩仔魚3件、土虱1件、尼羅紅魚1件及黃花魚1件等54件。依據行政院衛生署97.01.11署授食字第0971800008號公告方法以液相層析串聯質譜法(liquid chromatography tandem mass spectrometry)利用電灑游離法(electron spray ionization)配合多重反應偵測模式(multiple reaction monitoring)進行動物用藥孔雀綠及其代謝物之殘留量調查。結果甲魚4件、石斑魚1件及午仔魚1件與規定不符，不合格率11.1%。不符規定之檢體皆發布不合格食品資訊，並由地方衛生權責機關依法處辦。

A survey of malachite green (MG) and leucomalachite green (LMG) residues in marketed aquatic products was conducted in 2008. Fifty-four samples, including 12 milkfish, 10 tilapia, 8 perch, 6 grouper, 5 soft-shell turtle, 4 ell, 3 lake candidus dace, 3 fish larva, 1 catfish, 1 red tilapia and 1 yellow croaker, were collected from retails by local health officials. The samples were analyzed by liquid chromatography tandem mass spectrometry (LC/MS/MS) with electrospray ionization and multiple reactions monitoring, which was promulgated by the Department of Health (DOH) of Taiwan. The MG and LMG residues in 4 soft-shell turtle, 1 perch and 1 lake candidus dace samples were detected, which violated the regulation. The rate of violation was 11.1%. The result of this survey has been posted and the local governments have enforced the penalties to the suppliers who provided the violative samples.
