A traceability system for agricultural product quality and safety based on risk evaluation results
Aims:A risk assessment model for agricultural product quality and safety was established;and a traceability system for agricultural product quality and safety was designed and developed.Methods:Aiming at the difficulty of quantitatively evaluating the risk of quality and safety of agricultural products and the difficulty of tracing the source of risk due to the exceeding of heavy metal content,and based on the analysis of heavy metal characteristics and risk factors,a risk evaluation model of agricultural product quality and safety was established based on heavy metal characteristics and risk factor analysis,by utilizing the analysis methods of principal component analysis and multifactor nonlinear response,and combined with the multi-pilot sampling data by establishing a set of risk factors,risk evaluation indexes,and the index scoring method and weighting coefficients.Based on the results of risk evaluation,and combined with digital means,a traceability system of agricultural product quality and safety was designed and developed.Results:The traceability system of agricultural product quality and safety could realize the traceability query for the risk point of heavy metal enrichment and put forward the early warning information and relevant production suggestions based on the evaluation results and system prompts.Conclusions:The traceability system of agricultural product quality and safety based on the risk evaluation results can realize the quantitative research and visualized traceability of the risk of heavy metal enrichment in agricultural products,which is of good practical significance for the high-quality and digital control of agricultural product quality and safety.
