Research On Safety Evaluation System For Animal By-Products Quality Based On Traceability System

The consumption of animal by-products has been continuing to rise with the development of society and growth in people’s living standard. However, an increasing number of safety problems like poisoning and polluting have been triggered because of the quality problem of animal by-products, which directly influences consumers’health and environmental security. Eventually, it has aroused widespread concern in the whole society. Consumers find hard to get to know food quality for lacking of effective delivery of animal by-products manufacturing information. Confronting with the animal by-products risks, many researches on safety evaluation have been doing from the macroscopic perspective. But most of them just focus on the study of physicochemical harmful consequences caused by one specific animal by-product poisonous risk factors and on the research of its quality assurance regulations, not to mention the microscopic evaluation research on implied risks in the process of production. Therefore, the construction of one sound animal by-products traceability system and safety evaluation system is of great significance towards the management of food quality and safety, which has been becoming a matter of urgent concern by the government and consumers.In accordance with China’s situations of animal by-products traceability chain, this paper does research and tries to construct animal by-products safety traceability system and safety assessment system which are compatible with China’s situations. By the construction of these systems, it can be easily and effectively tracking and assessing, if some unsafe information in the animal by-products traceability chain coming out. The paper hereby displays the main contents and important achievements as fowllows:1) Via deeply analyzing and comparing the key factors and barcodes like individual identification, datastorage, trace positioning, terrain analysis, detection control, etc. relative to animal by-products safety traceability system, and digging into and comparing every automatic identification technologies like RFID, this paper puts forwards various key factors and technologies conforming to every links of animal by-products safety evaluation traceability system. By applying these key technologies in every link, it constructs the animal by-products safety traceability system which is composed of identification traceability management, individual traceability management, pollutant traceability management, provenance traceability management, etc. It sets up3-D frame model, namely, process, component, and risk. Under this modal, by using the methods of FD and AHP, it proposes risk-based framework model system and works out animal by-products safety evaluation index set.2) As for free-ranging link, based on the above framework model system, and by the reference to the standards and quality control mode research of GB, HACCP, GMP, SSOP, etc, this paper devises safety evaluation index system towards risk resisting ability, science&technology cognitive risk and breeding credit&d quality risk in the process of free-ranging.3) This paper improves limited tolerance relation, perfects its rough set classification accuracy and quality, and builds animal by-products risk decision-making model on the basis of limited tolerance relation rough set.4) On the basis of improving the classification accuracy and quality of limited tolerance relation rough set, this paper sets up animal by-products risk decision-making model on the basis of limited tolerance relation rough set.5) On the basis of analyzing risk factors of animal by-products manufacturing enterprises, it constructs animal by-products risk prediction model based on limited dominance rough set.6) Based on the above mentioned safety evaluation traceability system, it constructs comprehensive management system obtaining various animal by-products quality safety evaluation, traceable risk prediction and risk decision-making.
