The constructiveness of food safety makes it a complex social problem，therefore the study of deconstruction of food safety discourse has important theoretical and practical significance. From the three dimensions of discourse construction，this paper examines how organic agrifood is framed and justified in media discourses in China. Three hundred and nine articles published in Farmers’Daily from 2000 to 2016 are analyzed to examine actors，framing and justifications related to organic agrifood. The research suggests local governments and industries apply the concept of‘organic agriculture’to gain the reputation of developing high tech agriculture with little discussion about its substantive contents. In addition，science，technology and government policy are seen as crucial factors for organic agriculture development，and organic agriculture is framed as a part of—rather than an alternative to—the large-scale industrialized modern agriculture and food system. Finally，the lack of discussions about the connotation of organic agriculture，especially an absence of voices from actors in civil society，results in a strong emphasis on the industrial and marketing approaches to organic agriculture. Finally，the paper puts forward the three dimensions of‘organic agriculture’discourse construction，and discusses the theory and practice of creating a more cohesive discourse system suitable for food safety in China.
