Food safety evaluation based on the extension method and its application in export food safety supervision

In the proposed methods,the food safety status was divided into difference grades,and some evaluation features were designed,and the classical fields and whole real fields were established for every evaluation feature.And then the weight of each feature was determined,food safety status level for each hazard was obtained by calculating its dependent function.Finally,the wine data of full 2014 year,provided by an Entry- Exit Inspection and Quarantine Bureau,was used to evaluate food safety status. Supervising officer can identify high- hazard factor based on the results of the evaluation and draft scientific regulation basis for the future.
