: AIT當初美牛的解釋,節錄:
: Why Can’t the U.S. Just Ship Ractopamine-Free Beef to Taiwan?
: Because ractopamine is considered safe and has been approved for use in
: cattle, there is generally no segregation of the beef supply in the United
: States. As a result, ractopamine-free beef is available only from a limited
: number of small certified-organic ranches and processors. In fact, organic
: beef is estimated to account for less than 3 percent of total U.S. beef
: production.
: 美國只有低於3%的「有機美牛」牧場不含萊克多巴胺,
: 看來店家十分佛心,美國自己都十分稀少的有機美牛,台灣店家拿來做成牛肉麵;
: 而且還沒趁機打廣告是有機的?嘻嘻。
給大家看看JECFA當年討論Ractopamine的文件,裡面有提到牛隻的殘留狀況:
http://www.inchem.org/documents/jecfa/jecmono/v53je08.htm#abs
The length of time required for radioactive residues to reach steady state
was determined in groups of three cattle receiving [14C]ractopamine at 1.01
mg/kg bw per day for 4,7, and 10 days via rumen fistula. The concentrations
of 14C-labelled residue were determined in liver, kidney, muscle, and fat 12
h after the last dose. No detectable residues were measured in the muscle or
fat........ (Dalidowicz & Thomson, 1988).
簡單說,他們用碳14標定法餵牛吃含碳14的Ractopamine,停藥12小時後,牛肌肉跟脂肪
內就測不到碳14活性,即未檢出Ractopamine
所以店家公布未檢出的SGS文件,並不能證明他們的牛肉在飼養過程中沒有使用萊劑,
只能證明這批牛肉的Ractopamine含量<1ppb,符合10ppb的國際標準。至於現在進口
的美牛到底有多少是飼育過程中未使用Ractopamine,只能看美國市調了
