This study analyzed the effect of FMD on the prices of livestock products at each distribution stage. Through the sentiment analysis of FMD from 2005 to 2020, the Media tone index was used as a proxy variable to conduct VECM analysis. In particular, the long-term and short-term impact relationships were compared and analyzed, focusing on before and after the introduction of the Korea Animal Health Integrated System (KAHIS), which prepared the government’s systematic response system for epidemic prevention and control of livestock diseases. As a result of the analysis, after the introduction of the KAHIS, the positive media reports gradually increased in the media tone index on livestock epidemics. In addition, it was found that the adjustment of the livestock product distribution policy and food safety management system contributed to reducing the range of price fluctuations at each distribution stage.
