以欧洲食品法的风险预防原则为背景,首先对“预防”概念的相关问题进行介绍,然后介绍了基于欧盟食品法的风险预防原则,最后提出风险预防原则在世界贸易法领域的前景。从“风险预防原则”在欧盟食品法中逐渐成熟的历程,再到欧盟与美国对食品安全问题规制的相互联系,它们之间所存在的争论也是值得探讨的。 Based on the principle of risk prevention in the European Food Law, this paper firstly introduces the related issues of the concept of “prevention”, then introduces the principle of risk prevention based on the EU Food Law, and finally puts forward the prospect of the principle of risk prevention in the field of world trade law. From the “principle of risk prevention” in the process of gradual maturity in the EU food law to the interconnection between the EU and the United States on the regulation of food safety issues, the controversy between them is also worth discussing.
