Bird flu virus found in southwestern Japan


Authorities in southwestern Japan say they have found the H5 strain of bird flu virus in chickens at a local poultry farm.


Officials say they found the virus in several birds at a farm in Miyazaki City.

They carried out the testing after 30 birds were found dead there on Sunday.


Officials sent in about 200 people to cull all of the 42,000 chickens at the farm.

They also plan to complete burying the birds and disinfecting their barns by the end of Monday.


Authorities banned the movement of chickens and eggs within a 3-kilometer radius as well as their shipping to areas outside of a 10-kilometer radius.


They also set up 10 disinfection stations in nearby areas to keep passing vehicles from spreading the virus.
