    Completed incineration of over 150,000 bird flu birds in Himeji City
    December 01, 11:29

    Due to the bird flu that occurred in Himeji City in November, the prefecture announced on the 1st that the incineration of more than 150,000 birds at the incinerator in the city was completed.

    On November 17, a highly pathogenic "H5N1" avian influenza virus was confirmed in chickens found dead in Himeji City.
    Hyogo Prefecture has continued to incinerate at two facilities in Himeji City even after slaughter of about 156,000 chickens in the poultry farm and disinfection of the poultry house with the support of the Self-Defense Forces. Announced that it was completed at 6 am on the 1st.
    So far, no outbreaks of bird flu have been confirmed in other poultry farms in the vicinity, so we will gradually lift the restricted areas to prevent the spread.
    At midnight on the 3rd, the measures prohibiting the shipment of chickens within a radius of 3 to 10 km around the poultry farm were lifted, and at midnight on the 14th, the movement of chickens within a radius of 3 km was prohibited. We are going to cancel the measures we are taking.
    The Hyogo Prefectural Bird Influenza Countermeasures Headquarters Secretariat is calling for "The treatment of the bird flu that has occurred this time is proceeding smoothly, but the season will continue until spring, so please continue to be vigilant."

      Prevention of bird flu, order to disinfect poultry farms in Kumamoto Prefecture Governor Kabashima "Thorough hygiene management"
      Kumamoto Nichinichi Shimbun | December 06, 2021 19:46


       Following the outbreak of highly pathogenic avian influenza at a poultry farm in Nankan Town, Kumamoto Prefecture, Governor Ikuo Kabashima announced on the 6th that all 205 poultry farms in the prefecture that raise more than 100 chickens will be treated based on the Domestic Animal Infectious Diseases Control Law. We issued an order to disinfect the area around the poultry house and the site. The purpose is to prevent the spread of the virus. We are requesting completion by the end of January next year...

      ...In addition, the prefecture announced that the avian influenza virus that occurred this time was confirmed to be highly pathogenic to "H5N1 type" by genetic testing by a national institution. This is the third case of H5N1 type confirmation in Japan this season.

       When the prefecture conducted an urgent survey of 10 places such as migratory bird landings on the 3rd to 4th in the wild bird monitoring priority area with a radius of 10km from the outbreak poultry farm, no abnormalities such as mass death were confirmed. We will continue to monitor until January 2nd next year. (Ryosuke Takamune)

          Japan to slaughter around 130,000 chickens due to bird flu outbreak
          Published:
          Dec 31, 2021 05:36 GMT

          The authorities of the Ehime prefecture (Japan) will slaughter around 130,000 chickens due to an outbreak of bird flu.

          The highly pathogenic H5N1 virus infection was recorded in one of the local poultry farms. Subsequently, a sanitary zone was set up within a radius of three kilometers around the farm and disinfection points have been organized. The Asian country has already slaughtered around 400,000 chickens since autumn this year for similar causes.

              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.

                      1. Overview

                      (1) Genetic analysis conducted by the National Institute of Animal Health (Note) for pseudo-patients with highly pathogenic avian influenza confirmed at a farm in Yachimata City, Chiba Prefecture (14th case in Japan, confirmed as pseudo-patient on January 19) As a result, a sequence judged to be highly pathogenic was confirmed.
                      (2) In response to this, the Ministry of Agriculture, Forestry and Fisheries has determined that the poultry is a patient with highly pathogenic avian influenza based on the "Guidelines for the Prevention of Specific Livestock Infectious Diseases Concerning Highly Pathogenic Avian Influenza and Low Pathogenic Avian Influenza". ..
                      (3) In addition, as a result of examination by the National Institute of Animal Health for the highly pathogenic avian influenza virus, NA subtype was found and it was confirmed that it was H5N1 subtype.

                              Feb 12, 2022

                              Morioka, Iwate Pref. – The prefectural government of Iwate said Saturday that it has confirmed an outbreak of bird flu that is believed to be highly pathogenic at a chicken farm in Kuji.

                              The Iwate government will cull all 45,000 birds at the farm, while chicken farms located within a 10-kilometer radius of the farm will be asked to stop transporting chickens and products out of the area.

                              The Iwate government received a report from the chicken farm in Kuji about a rise in the number of deaths among its chickens...
