Exploration on the establishment of a food contaminants standards evaluation index system based on the Delphi method

ObjectiveTo explore the establishment of a food contaminants standards evaluation index system using the delphi method， and to provide certain reference basis for systematic evaluation and scientific improvement of food contaminant standards.MethodsExplore the establishment an evaluation index system for food contaminants standards through literature research， telephone interviews， delphi method， etc.ResultsThe evaluation index system of food contaminant standards was constructed initially， including 3 first-level indicators， 9 second-level indicators and 19 third-level indicators. The results of the expert consultation showed that the positive coefficient of the experts consultation was 100%， the coordination coefficient was 0.06-0.15， and the overall harmonization coefficient was 0.43， the difference was statistically significant by the chi-square test （P<0.01）.ConclusionThe evaluation index system of food contaminants standards initially constructed in this research can provide a certain reference basis for the systematic evaluation of food contaminants standards， provide reference suggestions for the further improvement， and provide a certain reference for the evaluation of other food standards.
