: AIT当初美牛的解释,节录:
: 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.
: 美国只有低于3%的“有机美牛”牧场不含莱克多巴胺,
: 看来店家十分佛心,美国自己都十分稀少的有机美牛,台湾店家拿来做成牛肉面;
: 而且还没趁机打广告是有机的?嘻嘻。
给大家看看JECFA当年讨论Ractopamine的文件,里面有提到牛只的残留状况:
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).
简单说,他们用碳14标定法喂牛吃含碳14的Ractopamine,停药12小时后,牛肌肉跟脂肪
内就测不到碳14活性,即未检出Ractopamine
所以店家公布未检出的SGS文件,并不能证明他们的牛肉在饲养过程中没有使用莱剂,
只能证明这批牛肉的Ractopamine含量<1ppb,符合10ppb的国际标准。至于现在进口
的美牛到底有多少是饲育过程中未使用Ractopamine,只能看美国市调了
