The slaughter of more than 10,000 chickens was ordered Saturday on a Japanese farm after avian influenza was detected in six birds, officials said.
The prefectural government in Miyazaki also imposed a 6-mile quarantine area around the farm where the infected birds were found, The Mainichi Daily News reported. That means no eggs or birds can be transferred within the area until the restrictions are lifted.
Miyazaki on the island of Kyushu is one of Japan's major centers for poultry production with almost 20 million birds in the prefecture. There are 46 farms in the quarantine area with 1.5 million birds.
In 2007, almost 200,000 birds were killed on three farms in the area.
Authorities said that by Friday afternoon, 36 dead birds had been reported at the Mori Furanjo Omagari Nojo farm. Tests were done on seven and the H5N1 virus was detected in six.
