台灣隨著國家不同時期的發展，在食品產業與食品供應系統產生巨大的改變。這些變化影響了食品安全的政策，使得食品安全政策著重的焦點在不同時期發生轉變。起初台灣在國民政府遷台，以恢復基礎工程、公共設施的政策下，著重於食品的「衛生」；爾後國家經濟發展與國民生活水準提高、消費者的意識抬頭、食品產業的轉型，食品安全政策從「衛生」轉移到注重因發展所帶來的汙染的「安全」上；在加入WTO後，食品產業踏入國際化，在新技術與食品來源複雜下，食品安全政策導入了「風險」觀念。 本研究採取Giddens的結構化理論來探究食品安全管理制度的轉變，食品產業在工業化的過程中改變了食品供應系統，糧食供應從農業社會到工商業社會造成社會結構改變，食品安全管理制度為行動者在面對食品工業化過程的社會實踐。在結論本文認為在食安事件中民眾反映出對食品工業化結構的反思認知能力，對於食品工業化使「從土地到餐桌」的過程變得既複雜又難以理解，大多數消費者看到的都是最終的成品，缺乏對於生產流程的認識。民眾擔心不只是某一樣的非法食品添加物或非食品原料被投入到食品生產之中；他們擔心的是整體：到底還有多少沒有被揭露？我還要承擔多大的食品風險？民眾對於食品安全的「安心」，其實核心在於資訊、透明、負責。除了讓物美價廉、物超所值的商品存在於市場，也允許品質高的食品得到應有的價值，讓消費者去做選擇。 / The food industry and food supply system have a huge change during the development of Taiwan. These changes have affected the policy of food safety, shifting the focus of food safety policy in different periods. At the beginning, under the policy of restore the infrastructures and public facilities. Taiwan government focused on the “hygiene” of food. After the economic development, the improvement of living standard, the rise of consumer awareness and the transformation of food industry, food safety policy shifted the focus from “hygiene” to the “safety” brought by the pollution from development. Joining the WTO, the food industry becomes more international. In the new technology and the complex of food sources, food safety policy added the concept of “risk”. This study adopts Gidden’s structuration theory to explore the change of food safety management system. The food industry has changed the food supply system during the process of industrialization. The change of social structure from the agricultural to modern society also changes the food supply. Food safety management system is the social practice for the actors in the face of the process of food industrialization.This study found that in the food crisis, the people reflect the cognitive ability of the process of food industrialization. Most consumers are lacked of awareness of the production process because they only see the final product. Food industrialization makes the process of “from the stable to the table” becomes both complex and difficult to understand. People worry that not only a certain kind of a certain kind of illegal food additives or non-food material are put into the food production. They are worried about the whole food industry. How much hasn’t been exposed？ How much risk do I still need to bear？ The core value of food safety is more information and more responsible.
