Abstract: In narrow sense,“ food sanitary”means that food is clean , not contaminated by pathogenic bacteria, and cannot lead to illness“.Food safety”means that food and the products related to food do not contain actual or potential harm, and that methods and measures have already been taken to maintain food safe. In contrast to“ food sanitary”,“ food safety” stresses more on reality, complement, exactness of food label, emphasizes more on the regulation of authentication and trade mark, pays more attention to methods of food eating, and concerns the differences among eaters more. Also, they differ rather obviously in public administration.“ Food quality”, a definition of“ degree”, means the degree of food quality, including both high-class food and low-grade food. Bu“tfood safety”is an“ absolute” definition, meaning that there is no acute or chronic danger in the food.“ Food sanitary” is also an“ absolute” definition. The opinion held in this paper is that we should discriminate the three definitions on the occasions of drafting the Food Safety Law and of amending the Standardizing Law and the Food Sanitary Law.
