    Politics Society Oct 27, 2022 22:09 (JST)

    Okayama, Oct. 27 (Jiji Press)--A highly pathogenic bird flu outbreak is suspected at a chicken farm in the city of Kurashiki in the western Japan prefecture of Okayama, the prefectural government said Thursday.

    The bird flu outbreak, if confirmed by a genetic examination, is the first in Japan this season.

    Once the outbreak is confirmed, the prefectural government will cull all chickens at the farm, totaling some 170,000, and restrict transfers of eggs and chickens from all farms within 10 kilometers of the farm in question.

    According to the farm ministry, no bird flu outbreak has occurred at any farm in the country in October or earlier. The earliest outbreak in a season so far is the one confirmed on Nov. 5, 2020...

    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.

            Fisheries

            As a result of genetic analysis conducted by the National Institute of Animal Health, it was confirmed that the pseudo-patients with highly pathogenic avian influenza (14th case in Japan) confirmed in Yachimata City, Chiba Prefecture, were patients with highly pathogenic avian influenza. rice field.
            In addition, the NA subtype of the highly pathogenic avian influenza virus was identified, and it was confirmed that it was the H5N1 subtype.

            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". ..

                          Bird flu outbreak confirmed at northeastern Japan farm
                          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...

                              Avian influenza in Kuji City turned out to be a highly pathogenic "H5N1 subtype" [Iwate]
                              2/16 (Wednesday) 19:13 delivery
                              IAT Iwate Asahi TV

                              The prefecture announced that it was a highly pathogenic avian influenza "H5N1 subtype" with a high case fatality rate due to the problem of bird flu that occurred at a chicken farm in Kuji City, Iwate Prefecture.
                              Following the first confirmation of bird flu in the prefecture from chickens on a poultry farm in Kuji City on the 12th, the prefecture requested the national government to perform genetic analysis. Analysis of two of the 13 chickens in the poultry farm revealed that they were highly pathogenic "H5N1 subtypes" with a high mortality rate. It is the same type of bird flu that was confirmed in Aomori and Chiba in 2021.
                              Also, on the 16th, the prefecture announced that a simple test for bird flu was carried out on one whooper swan recovered after death in Osanai-cho, Kuji City, and a positive reaction was confirmed. This is the 6th case of confirmed infection from wild birds.
