South Korea has been recognized by the OIE as a clean country for two types of fish diseases, becoming the first in the world to receive this distinction for a national-level designation. This status signifies that Korea has not experienced any outbreaks of these diseases, which are common in salmon and trout species found in European countries, in the past decade. The country's achievement is attributed to strict requirements, including no vaccination history and proof of no epidemic outbreaks, along with regular surveillance and scientific sample data. This status is expected to boost the consumption and export of Korea's rainbow trout by showcasing their disease-free status.
