Authorities culled about 780 chickens and ducks at the affected farm and ordered a standstill on all poultry facilities nationwide.
This outbreak marks the first highly pathogenic AI case at a domestic poultry farm since May 23, when the virus was detected at a farm in Changnyeong, South Gyeongsang Province.
