The current Food Safety Law only stipulates in principle the mandatory labeling of genetically modified foods, which makes the current regulations still too vague, incomplete, and prone to problems in practice. By sorting out the legislation on the labeling management of genetically modified foods, we believe that the labeling of genetically modified foods in China adopts the principle of mandatory labeling based on products and processes, and implements a process-centric compulsory labeling system in a negotiation-construction mode. There are still problems such as unclear definition of genetically modified foods, the main body of the labeling, the vague content, and unclear responsibilities are unclear. Finally, in view of the deficiencies and omissions in the current legislative level of genetically modified food labeling management, corresponding improvements are proposed.
