Abstract: Based on the documentations about the maximum residue limits (MRLs) for pesticides promulgated by the International Codex Alimentarius from 2008 to 2018, a complete database was established. The general situation, the number of items and the types of pesticides of MRLs standards in different product types were analyzed and summarized to reveal the changes of the Codex MRLs. The results showed that although the number of items and pesticide categories in the Codex MRLs standard showed an increasing trend year by year, and the main changes were concentrated in vegetables, fruits and mammalian products, the overall residual mean value of the Codex MRLs standard increased year by year. It was showed that although the International Codex Alimentarius Commission (CAC) had formulated more extensive codex MRLs standards for more products and pesticide categories, and the variations of different products and pesticide categories were different, the codex MRLs standards had a trend of relaxation in the overall residue mean, that was, CAC might be relaxing the codex MRLs standards. China should seize the opportunity of CAC relaxing the code MRLs standards, speed up the formulation and revision of the domestic pesticide MRLs standards, and reduce the losses of Chinas agricultural export trade caused by technical trade barriers formed by the adjustment of pesticide MRLs in various countries. The present research was of great significance to the improvement of Chinas food standard system, the improvement of Chinas food quality and safety level, the expansion of Chinas agricultural exports and the maintenance of Chinas legitimate rights and interests in international agricultural trade.
