Japan: H7 avian influenza in quails

27 February, 2009

Avian Influenza has been detected at a quail farm in the central Japanese city of Toyohashi, the government said Friday. Local authorities sequestered a 10-kilometre area around the farm.
No quail had died of the virus and no humans had been infected.
The quail had the low pathogenic H7 strain. The Toyohashi farm where the virus was detected holds about 320,000 quails and is a large producer of eggs. About 280,000 adult quails on the farm are expected to be culled to contain the virus.
The last time H7 avian flu was found in Japan was in 1925, when the virus infected chickens.
About 70 percent of quail eggs consumed in Japan are shipped from Aichi Prefecture. Sixty-five chicken and quail farms, keeping about 4 million birds, are located within 10 km of the infected farm.
Last spring, the H5N1 virus was detected in dead swans at Lake Towadako on the border of Aomori and Akita prefectures, and at Lake Saromako in Hokkaido.
