South Korean authorities detected H5 avian influenza antigen at a layer farm in Yeoncheon County, Gyeonggi Province, holding about 91,000 hens. It is the first domestic poultry site to test positive this winter, and a nationwide standstill order was in effect from November 4 to 5 while pathogenicity testing proceeds.
Culling of layer flocks reduces egg supply and lowers demand for feed grains in South Korea, a modest effect on global markets. Spread to more farms could widen the impact and tighten local egg supply.
