A preliminary study on the safety traceability management system of grasses and animal products

It has been reported that people was worried about the worse problems on food safety during the past several years. In developed country, tracing technology has been used in food and livestock product industry, especially the electronic information coding and stable isotope techniques. However, it has not been paid attention in the Chinese grassland farming systems. Based on above mentioned, on one hand, authors designed an electronic information coding technology that included the geo-coding, producing code, proceeding code and sale code of feed and animal product, and also the rules for managing those codes. On the other hand, a stable isotope technique was established, which needed to determine the tagged isotope element (δ2H, δ13C, δ15N, δ16O, δ32S, δ86Sr) from the forage, drinking water to organization, and then form isotope database according to those data, and the correlation between the isotopes of grasses and animal products was also analyzed by the technique of molecular biology and mathematical statistics technology to distinguish the influence factors of grasses and animal products safety. Above two tracking system based on principle of food traceability management covered the whole process of the entire production and supply of grass and animal product, which will provide a reference model for grasses and animal products safety management.
