13,000 Chickens Culled in Kagoshima; Avian Flu Cases Found in Poultry Farm


The Yomiuri Shimbun

13:49 JST, February 11, 2024

The Kagoshima prefectural government announced Sunday that roughly 13,000 chickens in Minami-Satsuma in the prefecture are being culled after DNA testing found cases of the highly pathogenic avian influenza at a poultry farm that raises chickens for meat. The culling is being done at neighboring poultry farms as well as the one where the cases were discovered. This is the 9th outbreak at a poultry farm in Japan so far this season.​..

<Immediate notification> Outbreak 9: Minamisatsuma-City1 On 10th February 2024, a Livestock Hygiene Service Centre (LHSC) in Kagoshima Prefecture received a notification from a domestic broiler breeding farm regarding an increase in the number of dead birds. The samples were collected from birds in the farm by prefectural veterinary officers and tested positive for influenza A virus by viral antigen rapid test. On 11th February 2024, the LHSC conducted RT-PCR and RRT-PCR tests and confirmed that the subtype was H5. On 12th February 2024, stamping-out and relevant control measures (including disinfection) of affected farm and one epidemiologically related farm were completed. On 14th February 2024, the National Institute of Animal Health (NIAH) conducted the sequencing and confirmed that the subtype of the virus was H5N6. The causative virus was determined as high pathogenicity avian influenza. Movement restriction and shipment restriction are imposed on farms within a radius of 3 km and 10 km of the affected farms respectively.

Effective Date: March 12, 2024—Hiroshima Prefecture



Effective on the date(s) listed above and until further notice, the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) is restricting the importation of poultry, commercial birds, ratites, avian hatching eggs, unprocessed avian products and byproducts, and certain fresh poultry products originating from or transiting the prefecture(s) listed above due to the detection of highly pathogenic avian influenza (HPAI) in domestic birds.



Under these restrictions, processed avian products and byproducts originating from or transiting any restricted prefecture and imported as cargo must be accompanied by an APHIS import permit and/or government certification confirming that the commodities were treated in accordance with APHIS requirements.



Importation as cargo of fresh, unprocessed shell/table eggs and other egg products, void of the shell (i.e., liquid eggs and dried egg whites), originating from or transiting any restricted prefecture is prohibited unless they are consigned from the port of arrival directly to an APHIS-approved breaking and pasteurization facility. An import permit and/or certificate is not required for these shipments when consigned directly to an APHIS-approved establishment.



Processed avian products and byproducts, including eggs and egg products, for personal use originating from or transiting a restricted prefecture, entering in passenger baggage, must:
  • have a thoroughly cooked appearance; or
  • be shelf-stable as a result of APHIS-approved packaging and cooking (i.e., packaged in hermetically sealed containers and cooked by a commercial method after such packing to produce articles that are shelf stable without refrigeration); or
  • be accompanied by an APHIS import permit and/or government certification confirming that the products or byproducts were treated in accordance with APHIS requirements.


Unprocessed avian products and byproducts originating from or transiting a restricted prefecture are not permitted to enter the United States. This includes hunter harvested, non-fully finished avian trophies and meat.



Importation of poultry, commercial birds, ratites, and hatching eggs originating from or transiting any restricted prefecture is prohibited. However, pet and zoo birds, pigeons, and doves may be imported under an APHIS import permit and will be subject to a 30-day quarantine at the New York Animal Import Center in Newburgh, NY, or the Miami Animal Import Center in Miami, FL.



These restrictions will be updated as additional epidemiological information is obtained. Additional information can be found on the APHIS website.

Highly pathogenic avian influenza confirmed at chicken farm, approximately 170,000 chickens to be disposed of
November 10th, 12:44

The national government conducted detailed tests on chickens that died at a chicken farm in Ishinomaki City, and found that the highly pathogenic avian influenza virus was detected.
The prefecture plans to dispose of approximately 170,000 chickens raised at this chicken farm.
This was reported at a countermeasure headquarters meeting held at the prefectural office on the 10th.
According to the report, on the afternoon of the 9th, a chicken farm in Ishinomaki City contacted the prefecture's livestock health and sanitation center to report that more than 200 chickens had died over two days.
The prefecture conducted genetic tests and found that avian influenza suspected to be highly pathogenic was detected, which was confirmed by tests conducted by a national specialist agency.
In response to this, the prefecture began disposing of approximately 172,000 chickens raised at this chicken farm from 11:00 a.m. on the 10th.
The culling is scheduled to take place over the 13th of this month, and the number to be culled is the second highest on record after the approximately 220,000 in fiscal 2016.
As a measure to prevent infection, the prefecture has also banned the removal of chickens raised at five farms within a 10km radius of the site, and has set up disinfection points in three locations around the poultry farm.
After the meeting, Governor Murai said, "The most important thing is to cull them quickly, and we will do our utmost. With the arrival of wild birds, the chances of an outbreak of avian influenza will inevitably increase. I would like to convey to farmers once again the importance of disease prevention."
This is the first time that an outbreak of avian influenza has been confirmed at a poultry farm in the Tohoku region this season.

[FONT=メイリオ]November 21, 2024
Ministry of Agriculture, Forestry and Fisheries[/FONT]


[FONT=メイリオ]The animal health research department conducted genetic analysis of the suspected highly pathogenic avian influenza (the ninth case in Japan) confirmed in Motosu City, Gifu Prefecture, and confirmed that it was a highly pathogenic avian influenza infected animal. In addition, the NA subtype of the highly pathogenic avian influenza virus was identified, and confirmed to be the H5N1 subtype.[/FONT]

[FONT=メイリオ]1. Overview[/FONT]

[FONT=メイリオ](1) Regarding the suspected highly pathogenic avian influenza confirmed on a farm in Motosu City, Gifu Prefecture (the ninth case in Japan, confirmed as suspected on November 19), genetic analysis conducted by the Animal Health Research Department (note) confirmed a sequence deemed highly pathogenic.
(2) In response to this, the Ministry of Agriculture, Forestry and Fisheries determined that the poultry in question was a highly pathogenic avian influenza infected animal, based on the "Guidelines for the Prevention of Specified Livestock Infectious Diseases Concerning Highly Pathogenic Avian Influenza and Low Pathogenic Avian Influenza."
(3) Furthermore, as a result of testing by the Animal Health Research Department, the highly pathogenic avian influenza virus in question was found to be the NA subtype, which was confirmed to be the H5N1 subtype.

Authorities begin culling after bird flu outbreak strikes Japan farm

STORY HIGHLIGHTS
The bird flu outbreak happened in the northern Iwate region and marks the 19th incident of the season, according to the Agriculture Ministry of Japan. Authorities started culling after tests confirmed bird flu as the cause of fowl deaths.

Japanese authorities have started culling about 50,000 chickens on Sunday (Jan 5) following a bird flu outbreak at a farm.

The outbreak happened in the northern Iwate region and marks the 19th incident of the season, according to the Agriculture Ministry of Japan.

The recent incident came to light after the farm reported increasing deaths of fowl, after which tests were conducted that confirmed on Sunday (Jan 5) the cause to be bird flu.​

The news has prompted authorities to begin culling 50,000 chickens, the regional government of Iwate said. Iwate has also imposed a ban on the movements of 170,000 birds from two other nearby farms that fall under a three-kilometre (1.86-mile) radius.

Apart from this, some 3.8 million birds that are kept within a 10-kilometre area are also to stay within the zone for now.

On Thursday (Jan 2), another farm in the Iwate with 120,000 birds and a company in the central Aichi region with 147,000 birds were affected by the virus and started killing the birds...
