市售畜禽產品中動物用藥乙型受體素類（β-Agonists）殘留量調查

Survey on β-Agonists Residues in Marketed Meat and Poultry

97年度市售畜禽產品檢體委由各縣市（政府）衛生局進行採樣，包括豬肉10件、豬內臟6件、牛肉5件、鴨肉6件及鵝肉10件等37件。以液相層析串聯質譜法(liquid chromatography/tandem mass spectrometry, LC/MS/MS)進行clenbuterol、terbutaline、salbutamol及ractopamine等4種乙型受體素類(β-agonists)殘留量調查。結果鴨肉及鵝肉各1件分別檢出salbutamol 0.47及7.45 ppb，與規定不符者5.4%，本調查結果已由本局發布新聞在案。

A survey of β-agonists residues including clenbuterol, terbutaline, salbutamol and ractopamine in marketed meat and poultry was conducted in 2008. Thirty-seven samples, including 10 pork, 6 swine liver, 5 beef, 6 duck muscle and 10 goose samples, were obtained from retailers by local health personnel. Samples were analyzed by liquid chromatography/tandem mass spectrometry (LC/MS/MS). The salbutamol was detected in one duck muscle (0.47 ppm) and one goose muscle (7.45 ppm) samples. Ratio of non-compliant samples is 5.4%. The result of this survey had been released to media.
