TOKYO - A highly pathogenic strain of avian influenza was detected in chickens at a poultry farm in Japan's Hokkaido after several chickens were found dead, marking the country's first confirmed outbreak for this season.

Hokkaido's authorities have begun culling approximately 19,000 chickens at the farm as a preventative measure, which is expected to be completed by Friday.
