A farm in southwestern Japan has culled 190,000 chickens to contain the seventh outbreak of avian flu in Miyazaki Prefecture and the tenth in Japan this winter.

The government has banned the transportation of eggs and chickens within six miles of the infected farm, and a meat processing factory was also closed down, according to authorities. Overall, more than 500,000 chickens have been culled in Japan since Jan. 22 due to various outbreaks.
