Avian influenza found at a poultry farm in Daisen City, Akita, which turned out to be a series of "H5N1 subtypes" nationwide.
4/21 (Thursday) 19:38
As a result of the prefecture's analysis of the avian influenza virus confirmed at the poultry farm in Daisen City, Akita Prefecture, it was found that it is the "H5N1 subtype", which has been reported nationwide this season.
On April 18, a veterinarian at a chicken farm in Daisen City reported that the number of dead chickens was increasing, and subsequent tests revealed that it was a highly pathogenic "H5 type" avian influenza virus. When the prefecture further analyzed the sample, it was found to be "H5N1 subtype".
The "H5N1 subtype" has been confirmed in 11 prefectures such as Hokkaido and Aomori prefectures this season, and is a different type from the avian influenza virus confirmed in Yokote City, Akita Prefecture in 2021.
In addition, the prefecture started incinerating 374 slaughtered chickens at the Prefectural Central Livestock Hygiene Center in Akita City from the 21st. The work is expected to take about a week.
On the other hand, an emergency simultaneous inspection has begun for all poultry farms in the prefecture. From the viewpoint of virus transmission, we are not inspecting on-site, but are asking whether the prefecture is spraying slaked lime through FAX and whether outsiders are restricted from entering.

Emu bird flu is highly pathogenic Ichinoseki facility, epidemic prevention measures completed
The prefecture announced on the 13th that the virus was a highly pathogenic "H5N1 subtype" over the bird flu infection of a large bird, Emu, which was bred at a facility in Ichinoseki City. The facility's epidemic prevention measures were completed by the afternoon of the same day.
At the facility, two emu birds that had been bred had a positive reaction in the prefecture's genetic test. The virus was analyzed by the Agricultural and Food Industry Technology Research Organization (Tsukuba City, Ibaraki Prefecture).
The prefecture has slaughtered a total of 10 emu and ostriches that had been bred in the same place in the facility, and completed the burial by the afternoon of the 13th. The disinfection work of the outbreak facility has been completed, and regular disinfection will be carried out in the future.

Status of occurrence of highly pathogenic avian influenza in wild birds (suspected case, Isehara City, Kanagawa Prefecture)
On September 25, 2020 (Sunday) in Isehara City, Kanagawa Prefecture, a weakened individual of a peregrine falcon was recovered and later died. On Monday, September 26, 2019, a simple test was conducted, and it was reported that a positive reaction to type A avian influenza virus was confirmed. This is the first suspected outbreak of highly pathogenic avian influenza in wild birds this season. In the future, we will conduct genetic testing for this case to confirm whether it is highly pathogenic avian influenza. In response to this report, we will designate an area within 10 km around the collection point as a priority area for wild bird monitoring and strengthen wild bird monitoring.

Bird flu sweeps through Japan, spreading at unusual pace
Jiji Nov 27, 2022
Cases of the highly pathogenic avian influenza, or bird flu, are spreading at an unusual pace in Japan, with 18 outbreaks confirmed this season through Saturday at poultry farms in 12 of the country’s 47 prefectures.
But that number is expected to rise further, in line with global trends.
The agriculture ministry is asking farms to take thorough infection prevention measures and to swiftly find and report suspicious cases.
On Oct. 28, the season’s first cases were confirmed at farms in Okayama and Hokkaido prefectures. The cases marked the earliest outbreaks in a season recorded in Japan.
This month, infections were reported intermittently in Kagawa, Hyogo and Ibaraki prefectures.
The number of chickens culled this season has totaled 2.89 million so far, already exceeding the previous season’s total of 1.89 million.
The largest number of bird flu outbreaks in a season in Japan stands at 52 outbreaks in 18 prefectures in 2020...
