供應鏈的迅速發展導致物品間的流通更加快速且雜亂，近年來，食品安全問題日漸頻繁，食物中毒與不良食品的現象層出不窮，其中，不良食品氾濫因而無法確定源頭，導致供應商常無法及時改善自家食品；另外，產品標示不清及黑心食品事件在臺灣時有所聞，而市面上更充斥著不實產地、日期、添加物的產品，讓國人的健康安全岌岌可危。有鑑於上述之問題，若能將生產履歷導入農漁畜牧業與加工食品，將能夠有效地提供明確且可追蹤的訊息標示。消費者可由已認證的生產、加工與運送過程中，購買到具有保障的食品，防止食品安全事件的發生。本研究將以農產品—茶葉為研究的主軸，從供應鏈流程角度，建立導入生產履歷系統之流程模型，以提供茶葉產業之食品導入生產履歷系統時的參照流程模型。同時也將本研究模型提供國內其他農畜產業，作為建置生產履歷系統時之參考。

Currently, supply chains are rapidly developing, and the flow of foods items are accelerating and sometimes chaotic. Due to the problems of food poisoning and defective products, people have begun to increase their focus on food safety. However, without the ability to determine the source of defective foods, exerting pressure on suppliers becomes problematic, and suppliers not have been able to respond immediately to the necessity for product improvement. Agriculture is an integral part of the food chain, but the safety of agricultural products has continued its precipitous decline in Taiwan. For example, product labeling is unclear, and some unsafe food contains poisonous substances; these lead to risks for people’s health and safety. Due to these problems, implementing a traceability system for animals, fish, and agricultural products will be allowed to clear and effective messages regarding food safety. Consumers can buy insurance-food from certified production, processing, and delivery streams, to guard against unsafe products. This study, using the tea industry as an example, proposes a process analysis model from agricultural supply chain for a traceability system. Furthermore, the model provides a reference for other domestic food producers who seek to establish traceability systems.
