Q3: How much additional withdrawal time does it take to go from the FDA tolerance level (0.05 PPM) to a level that would test negative or free of ractopamine in most tests (0.25 PPB)?
A3: Unfortunately, there is not a study that directly measures this. At a minimum, ractopamine can be detected for 42 days after the end of feeding in pig hair. However, we do know that carcass changes induced by ractopamine are not permanent and begin to revert to the animal’s baseline phenotype as soon as ractopamine is removed. So, it is likely that most or all benefit of feeding ractopamine would be lost by the time that the pig tested negative.

問題3：從FDA的容忍度(0.05 PPM)到在大多數測試中測試為陰性或不含萊克多巴胺的水平(0.25 PPB)，需要多少額外的戒斷時間？
答3：很不幸地，目前還沒有一項研究可以直接測量這個水平。至少，在豬毛中可以檢測到萊克多巴胺在飼喂結束後的42天內。不過，我們知道，萊克多巴胺引起的胴體變化並不是永久性的，一旦萊克多巴胺被去除，就會開始恢復到動物的基線表型。因此，當豬隻檢測結果為陰性時，飼喂萊克多巴胺的大部分或全部好處很可能已經喪失。

照這篇的說法，
等萊克多巴胺代謝乾淨的時候，
豬的體形也會打回原形，等於作白工。
也就是養豬戶不會等萊克多巴胺代謝乾淨才賣豬。
