Abstract: This paper has clarified the principle,methods and the implementary key point for building the information management system about edible farm produce safety,and adoptsed GPS(global positioning system),GIS(geographical information systems)and RFID(radio frequency identification)as the main technological support.Depending on the international general criterion of“EAN·UCC”to track and cast back the information of edible farm produce,it is feasible to realize the identification of reliability and information transmission in the whole process of supply chain including producing, manufacturing,packing,circulating,storing and consuming.Establishing a perfect data system which integrates all the data and information coming from the complete supply chain on a uniform management platform and makes use of this platform,it is possible for the supervision department to supervise the whole process.Furthermore,corporations may make use of this platform to strengthen microcosmic safety management in addition to guarantee the transparency of the complete process of manufacture,storage,transportation and distribution,so as to eliminate the information dissymmetry,and to satisfy consumers’ right of understanding the inside story and choices.Consequently,it will enhance the level of informationization and production efficiency of farm produce,and ensure the entire safety of farm produce from farm to table sequentially.

Key words: supply chain, edible farm produce safety, information management system
