This study focuses on animal infectious disease issues. The animal infectious disease issues in the line of new security, which are transnational, and difficult to observe how may they intensify. So, it is difficult to cope with the complete termination after the onset, and the whole process is costly. Furthermore, in the process of resolution, the domestic interests surrounding the infectious animals may conflict, causing social confusion and distrust. In other words, the issues of animal contagious diseases can severely damage national security, which requires significant attention and strategic responses. Existing studies of security have taken a structural approach that seeks international cooperation with infectious disease issues. On the other hand, this study argues that, as new security distinguished from traditional security, domestic consensus on crisis management for animal infectious diseases should be preceded by a solution of international cooperation theoretically. The case of African swine fever among animal infectious diseases is analyzed to see how animal infectious diseases affected the South Korean security risk management strategy.
