Japan's Ministry of Agriculture, Forestry and Fisheries confirmed a highly pathogenic avian influenza outbreak at a poultry farm in Yuni Town, Hokkaido, on December 29, 2025. This marks the 11th such case in the country since the current flu season began in autumn, with over 6,000 egg-laying chickens culled to prevent further spread.
Authorities have imposed strict containment measures, including bans on poultry and egg transportation within a 10-kilometer radius of the affected farm. The ministry emphasized adherence to biosecurity protocols, requiring incineration and burial of all culled birds. Japan’s avian flu season, which typically peaks between autumn and spring, has already led to the destruction of nearly 3.65 million chickens nationwide this year.
Hokkaido, where the first case of the season was detected on October 22, remains a focal point for monitoring. Experts warn that prolonged cold weather could exacerbate transmission risks. The outbreak has raised concerns among regional poultry traders, though no immediate disruptions to egg or poultry supplies have been reported.
Local officials urge farmers to report unusual bird deaths promptly. "Timely reporting is critical to containing outbreaks," said a ministry spokesperson. The situation is being closely watched by neighboring economies, particularly amid ongoing efforts to stabilize Asia’s food supply chains.
