(Central News Agency reporter Zhang Xiongfeng, Taipei, 20th) The Council of Agriculture stated today that H5N1 subtype highly pathogenic avian influenza was detected in duck breeding farms in Wujie Township, Yilan County, and wild ducks in Sicao Wetland, Tainan; There were 27 cases of avian influenza in poultry farms (21 farms of land poultry, 4 farms of ducks, and 2 farms of geese).
The Animal and Plant Epidemic Prevention and Quarantine Bureau of the Agriculture Committee of the Executive Yuan issued a press release tonight stating that according to the standard operating procedures, the Yilan County Animal and Plant Epidemic Prevention Institute has carried out the culling and destruction operation of 5,010 breeding ducks aged 3 to 104 weeks, and supervised the industry. Complete the cleaning and disinfection of the field; for the wild ducks in the wetland, the Tainan City Animal Epidemic Prevention and Protection Department will carry out regional environmental disinfection and monitoring of surrounding poultry farms.
The Bureau of Defense Inspection pointed out that the viruses of the breeding ducks and wild ducks are both highly pathogenic avian influenza viruses of the 2.3.4.4b branch H5N1 subtype, but the sequence similarity of the hemagglutinin (HA) gene fragments between the two is only 97.8%. It also shows that the nucleic acid sequences of the virus are similar to the two virus groups under the 2.3.4.4b branch from 110 to 111 in the Republic of China. It is preliminarily determined that the detection of H5N1 virus in Yilan ducks and Tainan Sicao wild ducks are two independent events, and there is no molecular epidemiological relationship. .
In addition, the viruses of the two cases are different from the H6N1 subtype of the Taiwanese poultry farm, the H5N2 subtype of the Mexican strain, and the H5N2 subtype of 2.3.4.4b, and are emerging avian influenza viruses.
The Bureau of Defense Inspection pointed out that in response to the detection of H5N1 subtype HPAI emerging avian influenza virus in domestic duck farms and wild ducks, in order to effectively prevent the spread of the pathogen, it has started to expand the monitoring of poultry farms around the duck farms (from 3 kilometers to 5 kilometers in radius); In addition, we will continue to strengthen the monitoring of wild migratory bird discharge in important wetlands across the country. If a positive case is found, the local animal epidemic prevention agency will immediately take necessary measures.
The Bureau of Defense Inspection calls on poultry farmers to strengthen bird-proof facilities in poultry houses to avoid contact between poultry and migratory (wild) birds, and at the same time implement access control. All vehicles, cages, appliances, etc. entering and exiting must also be thoroughly disinfected to improve the self-prevention function of the site, effectively prevent the spread of bird flu through different media, and reduce the risk of new virus invasion and spread.
