複製動物作為食用目的，成分組成上是否安全無虞？以現階段的科學工具，是否足以證實複製動物作為食物用途絕對安全？人類目前是否具有反向追蹤源自複製動物製成食品的能力？道德的考量上，複製動物作為食用用途是否符合哲學、神學以及社會價值判斷上的道德標準？法規要求相關資訊的公開應該到何種程度？複製動物相關的專利議題該如何訂定？各國不一致的立法是否成為自由貿易的妨礙？各國對待複製動物議題的法規如何規範？所欲據以保護的法益為何？最後，對此議題，我國現有法規並不完整，甚至有些方面付之闕如。預防原則（precautionary principle）在政策與立法的過程中該具備何種角色？要循美國模式或歐盟模式，甚或自行發展一套適合我國民情的方式，是值得立法者以及相關行政單位深思熟慮的問題。

On the issue of cloned animals as food, is there sufficient scientific evidence to secure it’s safe to human health? Do we have the ability to reverse-trace food from cloned animals? And how about the perspectve of moral, do cloned animals for food meet philosophy, theology and even moral standards of social value judgments? To what extend should the regulatory requirements of the relevant information to be disclosed? Does cloned animal meet the patent requirement? If it does, then how to set? Whether national legislation inconsistence becomes to hinder free trade? Finally, on this issue, our existing laws and regulations are incomplete. How to incorporate the precautionary principle in the process of policy making? Should we follow the American model or the European model, or for our own national feelings to develop a new one. This is a serious topic to legislators and the associated administrative units.
