Food input risk monitoring and early warning method

Abstract

The invention belongs to the technical field of food safety, and particularly relates to a food input risk monitoring and early warning method. The method comprises the following steps: step 1, acquiring spot check qualified batches and spot check unqualified batches of local produced food and foreign input food in a region; step 2, estimating prior distribution of the qualified rate of the food type according to the food type; step 3, according to the data obtained in the step 1 and the step 2, obtaining the posterior qualification rate of the locally produced food and the foreign input food by using empirical Bayesian estimation; and step 4, inspecting the posterior qualification rates of the locally produced food and the foreign input food obtained in the step 3, and performing input risk early warning on food types and areas with significant differences in the posterior qualification rates. According to the method, the problems that the number of input food sampling inspection batches is small, and the calculated qualified rate deviates from the real qualified rate are solved, the analysis result of the food input risk can be more accurately obtained, and the method has good application prospects.

Description

technical field [0001] The invention belongs to the technical field of food safety, and in particular relates to a method for monitoring and early warning of food import risks. Background technique [0002] Food safety risk prediction and early warning refers to timely warning of potential food safety problems through monitoring, tracking, quantitative analysis, information notification and forecasting of food safety hidden dangers, so as to achieve early prevention and control of food safety incidents and minimize losses , Change post-event processing for the purpose of early warning. [0003] Food safety risk prediction and early warning is currently valued by many countries around the world, and plays an important role in food safety supervision. At present, my country's "Food Safety Law" has made it clear that food safety work should implement the principles of focusing on prevention, risk management, whole-process control, and social co-governance. Conduct a comprehens...

AI Technical Summary

Problems solved by technology

Due to the small number of testing batches, the calculated failure rate of input food usually has a certain difference compared with its true value

However, for the food types with a low pass rate in spot checks (that is, the food safety risk itself is relatively large), the impact of this difference is more significant

This problem has greatly affected the accuracy of the safety risk monitoring and early warning of imported food.
