We were informed by a layer poultry farm in the central part of Yamaguchi Prefecture that they had discovered some dead chickens. In seven open poultry houses they raise about 35,000 chickens. The reported number of the dead chickens was small in the beginning, but soon it increased dramatically. As the result of development egg inoculation it was confirmed that they died of High Pathogen Avian Influenza (HPAI). In order to prevent further infection, measures were taken immediately. We gave special attention to the issues, such as 'systematization and the establishment of a line of command,' 'higher efficiency of destroying chickens,' and 'improvement of dropping disposal.' The killed chickens were buried. Thanks to the early report, the correct diagnosis, and the timely measures, the epidemic was contained and the whole problem was solved in ten days. In the future it will be necessary to strengthen preventive measures to protect humans and to define final and large-scale disposal methods.
