South Korea confirmed its first highly pathogenic avian influenza case of the 2026–27 winter season at a layer farm in Yeoncheon, Gyeonggi Province, and an H5-type virus was detected at a meat-duck farm in the Jeonnam–Gwangju area. The Korea Poultry Association for Layers said it would step up biosecurity guidance and send farmers daily updates on outbreaks, local risks and prevention measures.
Further infections could reduce layer or poultry output and tighten regional supplies, putting upward pressure on egg and poultry prices. The article reports one confirmed layer-farm case and prevention measures, not a broad supply loss.
