Through the sharing of the pollution-free agricultural products certification resources, the transparency of pollution-free agricultural products information was improved greatly. It also promoted the healthy and orderly development of the pollution-free agricultural products and provided the technical support for the transition of the authentication work from the evaluation of conformity to the market supervision of the agricultural products quality safety.
