Decapod iridescent virus 1 (DIV1) is a dangerous new virus that causes mortality to shrimp and crayfish. This virus has been reported in China, which is a major exporter of decapods to South Korea and its neighboring countries, Taiwan and Thailand. This virus can be regarded as a pathogen with a high risk of entry into Korea. Therefore, South Korea has been conducting emergency quarantine for DIV1 since 2020, and in this study, an import risk analysis was performed following the World Organization of Animal Health and domestic laws and regulations to present scientific grounds and validity for South Korea’s DIV1 emergency quarantine. Import risk analysis was performed by hazard identification, entry assessment, exposure assessment, and consequence assessment. As a result of the import risk analysis, it was confirmed that the current DIV1 quarantine can significantly reduce the import risk. However, it was also established that the management of prawns and polychaetes intended for animal feed or bait and currently not subjected to quarantine is also required. Additionally, two species of crabs that would meet the criteria for a completely susceptible species and two species of crayfish that required surveillance of the import amount or route of exposure were also identified. In conclusion, these uses and susceptible species were designated as quarantine targets for nonhuman consumption requiring risk management and import sanitary conditions to be performed before export and after import. Finally, alternatives to reduce the cost burden of stakeholders following the introduction of the system were also presented.
