STAFF WRITER
APR 13, 2014
The agriculture ministry announced Sunday a suspected outbreak of bird flu that killed at least 1,100 chickens at a farm in Taragi, Kumamoto Prefecture, prompting the prefectural government to order the culling of 112,000 chickens kept there and at another nearby farm run by the same operator.
The ministry also ordered a ban on the shipping or moving of chickens and their eggs within a the 3-km radius of the two farms, and requested that reporters not approach the farms to prevent further spread of the suspected H5-type avian influenza outbreak.
In an apparent bid to ease public concerns, government officials noted in a statement that no cases of bird-to-human bird flu infection through eating chicken meat or eggs have been found in Japan.

Japan’s bird flu virus has same gene type as South Korea’s
The virus strain that caused bird flu at a poultry farm in Kumamoto Prefecture has been confirmed to be genetically identical to the one found in South Korea, the National Institute of Animal Health said Tuesday.
Genome sequencing conducted by the institute proved the virus strain detected April 13 on the farm in the town of Taragi, Kumamoto Prefecture, was at least 99 percent identical to the virus that has led to widespread infections in South Korea this year.
There is little chance that the virus will directly affect humans, according to the institute.
KUMAMOTO—Restrictions on poultry shipments put in place due to an outbreak of highly virulent avian influenza in Taragi, Kumamoto Prefecture, have been lifted because recent tests for the virus have all been negative, the prefectural government said Thursday.... http://the-japan-news.com/news/article/0001252339
