The article examines the different strategies employed by countries like the U.S., Europe, and Japan for preventive culling during livestock disease outbreaks. It notes that while the U.S. and Europe enforce culling within specific radii, such as 3km from the outbreak site, Korea is exploring a more targeted approach by reducing the culling radius to 500m if the risk is deemed low. The Korean Ministry of Agriculture, Food and Rural Affairs is assessing this method and considering its application to more livestock species to mitigate damage.
