South Korea confirmed its first highly pathogenic avian influenza case of the 2026-2027 winter season at a layer farm in Yeoncheon, Gyeonggi Province, housing about 91,000 birds. Authorities imposed a 24-hour nationwide poultry movement standstill and a two-week disinfection campaign.
Layer losses and movement limits can tighten domestic egg supply and raise feed demand for layer rations. Effects on global feed prices are likely small unless outbreaks spread widely.
