Kyoto prefecture authorities reported on November 11 that a chicken farm in Kameoka city showed suspected highly pathogenic avian influenza, with rapid tests positive on 10 dead birds. Gene testing was expected on November 12, and if confirmed, all roughly 200,000 chickens on the farm would be culled.
Movement of poultry and eggs is restricted within 10 km of the farm.
Culling 200,000 layers would tighten Japan's already record-high egg supply, adding to demand for imported feed and supporting egg prices; the impact on feed ingredients is limited given the scale.
