Another bird flu case prompting massive chicken cull in Japan
KYODO
JAN 16, 2015

OKAYAMA – The Okayama Prefectural Government said Thursday that it has confirmed the presence of a pathogenic H5 strain of bird flu virus at a chicken farm in the prefecture, the fourth case of avian influenza detected at a poultry operation in Japan this winter.

Local government officials have requested the Self-Defense Forces to dispatch troops to help cull roughly 200,000 birds at the farm in Kasaoka, an operation they plan to begin on Friday and estimate will take four days to complete.

The previous three cases this winter have resulted in the killing of thousands of chickens, ranging from 4,000 to 42,000 per instance.

Late Thursday night, Prime Minister Shinzo Abe ordered the agricultural ministry and other relevant government offices to promptly implement epidemic prevention measures.

The farm ministry announced that it is sending senior vice minister Toshiko Abe to the prefecture to oversee the situation and measures to be taken.

The hatchery in Kasaoka reported to the local livestock health center Thursday morning after 28 of its birds were found dead beginning on Wednesday.

A preliminary check found that four of the dead and one living chicken tested positive. A further genetic test confirmed the virus.

The prefectural government has subsequently imposed a ban on the movement of chickens and eggs at six farms within a 3-km radius of the Kasaoka farm. In a 3- to 10-km radius, 15 other farms have been ordered not to ship their products outside the area.

The 21 farms raise nearly 1 million birds.

Okayama is the fourth-largest chicken egg producing prefecture, with around 10 million birds, according to national data as of February.

The latest case comes after bird flu cases at two farms in Miyazaki Prefecture and another in Yamaguchi Prefecture in December.

In 2007, Okayama Prefecture culled around 10,000 chickens after a highly pathogenic virus was detected in the city of Takahashi.

Okayama, Jan. 15 (Jiji Press)--An outbreak of highly pathogenic bird flu has been confirmed in the western Japan prefecture of Okayama, prefectural government officials said Thursday.
Chickens that died at a poultry farm in the city of Kasaoka tested positive for H5 subtype avian flu virus in a genetic test, the officials said.
This was the fourth case of highly pathogenic bird flu in Japan this winter, following two in the southwestern prefecture of Miyazaki and one in the western prefecture of Yamaguchi last month.
All 200,000 chickens at the Kasaoka farm will be slaughtered, beginning Friday morning. Okayama Governor Ryuta Ibaragi asked Self-Defense Forces troops to be deployed to help with the culling process, expected to take about four days.
The Okayama prefectural government prohibited poultry within a radius of 3 kilometers from being moved and banned shipments of chickens in farther areas within 10 kilometers, following the guidelines of the central government.

Tokyo (dpa) - Authorities started to dispatch about 200,000 chickens in western Japan Friday after a local government said it had confirmed a highly pathogenic strain of H5 avian influenza in the fourth outbreak reported in the country this winter.

The Okayama prefectural government has requested military troops to help with the operation at a chicken farm in Kasaoka city, 600 kilometres west of Tokyo, because of its larger scale.

Authorities expected it would take four days.

Previous culls this winter have ranged from 4,000 to 42,000 birds.

The chicken and egg farm had reported Thursday morning that increasing numbers of birds were found dead.

A preliminary test showed four dead and one living chicken tested positive for the virus, which was confirmed in a further genetic test, the prefectural government said.

Prime Minister Shinzo Abe ordered the Agricultural Ministry late Thursday to promptly implement epidemic prevention measures.

The latest case came more than two weeks after 37,000 chickens were culled in Yamaguchi prefecture after the same strain of bird flu was found there.

Authorities in Miyazaki prefecture also culled 4,000 chickens on December 16 after a farm in the city of Nobeoka reported cases of bird flu. They were the first bird flu cases in Japan since April.

Epidemiological comments On 15 January 2015, the local veterinary service in Okayama prefecture received a notification from a layer farm on an increase in the number of dead birds. The samples were sent to the laboratory of the local veterinary service centre (Okayama Livestock Hygiene Centre). The samples from dead birds were influenza A virus positive by antigen-capture kits. On the same day, the centre started RT-PCR test and confirmed that the subtype was H5. Stamping-out policy is applied to the affected farm. Destruction of all the susceptible birds in the affected farm (approx. 200,000 birds) is ongoing. Movement restrictions are imposed on the farms within the radius of 3km of the affected farm. Shipment restrictions are imposed on the farms within the radius of 3-10km of the affected farm. The pathogenicity and the NA subtype have not yet been identified and are going to be determined by the National Institute of Animal Health (NIAH). Follow-up information on the second outbreak in poultry in Miyazaki reported in the follow-up report No. 7: On 13 January 2015, shipment restriction (3-10km radius around the affected farm) was lifted since the second confirmation test of the farms within the movement restriction zone proved freedom from avian influenza virus. The confirmation test used clinical inspection, serum antibody test and virus isolation and obtained negative results in all the tests. Follow-up information on the outbreak in poultry in Yamaguchi reported in the follow-up report No.8: On 16 January 2015, shipment restriction (3-10km radius around the affected farm) was lifted since the second confirmation test of the farms within the movement restriction zone proved freedom from avian influenza virus. The confirmation test used clinical inspection, serum antibody test and virus isolation and obtained negative results in all the tests.
