Avian influenza disposal proceeds
January 06, 12:55

At the poultry farm in Saijo City, Ehime Prefecture, where bird flu was confirmed one after another, about 170,000 birds were disposed of by 8 am on the 6th.
In addition, as a result of genetic analysis, it was confirmed that the first case is the same virus as the type detected in various parts of this season.

In Ehime Prefecture, avian influenza virus was detected in chickens at a poultry farm in Saijo City on December 31, and new infections were confirmed at two other poultry farms in Saijo City on the 4th.
One of them manages another poultry farm in Imabari City, so the prefecture is disposing of about 230,000 poultry farms raised in these three places.

According to the prefecture, about 170,000 birds were disposed of at the two poultry farms in Saijo City by 8 o'clock on the 6th.
In addition, as a result of genetic analysis of the virus detected in the first case, it was confirmed that it was a highly pathogenic "H5N1 type" with a high mortality rate detected in various places this season.
In addition, as a result of investigating 10 places such as the landing sites of migratory birds around the poultry farm where bird flu was confirmed, no abnormalities such as the death of a large number of wild birds were confirmed.
The prefecture will continue to strengthen surveillance and rush to dispose of it.

Kagoshima / Nagashima-cho bird flu confirmed to be "highly pathogenic" [01/14 19:56]

A national genetic test on the avian influenza virus found at a chicken farm in Nagashima Town, Kagoshima Prefecture, revealed that it was a highly pathogenic "H5N1 subtype" virus. With this, highly pathogenic avian influenza has been confirmed in 3 cases this season.

The prefecture completed the culling of about 51,000 chickens on a farm where the virus was confirmed before dawn on the 14th. The manager is also slaughtering about 57,000 suspected infected birds on another farm, which is scheduled to be completed on the 15th.

Highly pathogenic bird flu Over 80% of chickens are disposed of at a poultry farm in Shiraoi Town
April 20, 16:11

Due to the problem that bird influenza virus was detected one after another from dead birds on two farms in Hokkaido, the progress rate of the slaughter that is being carried out at the chicken farm in Shirao Town on the 20th was 82.7%. Announced.

In Hokkaido, a dead chicken was found at a poultry farm in Shiraoi Town, and a large bird "Emu" was found dead at a farm in Amisato City, both of which are highly lethal "H5N1 type" highly pathogenic birds. Influenza virus has been detected.
According to the person in charge of the road, about 430,000 of these farms, which is 82.7% of the 520,000 chickens in captivity, have been slaughtered at the poultry farm in Shiraoi Town.
On the other hand, at the farm in Abashiri City, it was expected that the slaughtered birds would be buried and disinfected on the 19th, but the work was continued for 20 days because it took time to transport the buried objects. It means that it is.
"Abashiri's measures are nearing the end and are expected to be completed by the end of the day. The slaughter of Shiraoi is proceeding smoothly," Kazu Yamaguchi, director of the Ministry of Agriculture's Ministry of Agriculture's Safety Promotion Bureau, said at a press conference. I did.
