Japan raised its avian influenza threat level to high after H5N8 was confirmed at a 143,000-bird laying farm in Akita and an H5 variant was found in Kagoshima. Surveillance zones and culling were ordered, and a suspected case was reported at an egg farm in Izuma.
Outbreaks in Japan and South Korea can trigger import restrictions and reduce domestic egg and poultry supply, supporting demand for imported poultry feed ingredients and meat. The effect on grain and meal prices is modest because the affected flocks are small relative to global feed use.
