Sunday, November 20, 2022 at 7:03 am

(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.

Taiwan's first H5N1 bird flu outbreak
According to Taiwan's "Zhongshi News Network" report, Taiwan's Wujie Township Duck Breeding Farm in Yilan County, Taiwan and Tainan Sicao Wetland Mallard Duck Waste
A new H5N1 subtype of highly pathogenic avian influenza was detected, and the Yilan duck breeding farm was the first poultry farm in Taiwan where H5N1 broke out...
5 hours ago

According to Taiwan's "Zhongshi News Network", a new type of H5N1 subtype of highly pathogenic avian influenza was detected in the duck breeding farm in Wujie Township, Yilan County, Taiwan and the wild duck row in Sicao Wetland, Tainan. Taiwan's first poultry farm where H5N1 outbreak occurred. Taiwan's agricultural department stated that most of the existing waterfowl houses are open, and it is difficult to distinguish them from wild and migratory birds.

In response to the H5N1 epidemic, the Yilan County Animal and Plant Epidemic Prevention Institute has carried out a culling and destruction operation of 5,010 breeding ducks aged 3 to 104 weeks, and supervised the industry to complete the cleaning and disinfection of the site; the wild duck part of the wetland was managed by The Tainan City Animal Epidemic Prevention and Protection Division conducts regional environmental disinfection and monitoring of surrounding poultry farms. Since 2022, 27 cases of avian influenza have been confirmed and culled in poultry farms (21 land poultry farms, 4 duck farms, and 2 goose farms).

According to the statistics of the Bureau of Prevention and Inspection, the viruses of the breeding ducks and wild ducks in this case are both 2.3.4.4b branch H5N1 subtype highly pathogenic avian influenza virus, but the sequence similarity of the hemagglutinin (HA) gene fragments between the two is only 97.8% , Genetic analysis also showed that the nucleic acid sequences of the virus were similar to the two virus groups under the 2.3.4.4b branch from 2021 to 2022, and it was preliminarily determined that the detection of H5N1 virus in Yilan ducks and Tainan Sicao ducks was two independent events, and there was no molecular epidemic learning connection.

Huang Jincheng, vice chairman of Taiwan's agricultural department, explained that unlike the existing H5N2, H5N2 usually does not have symptoms in ducks, but ducks will also have obvious symptoms and die after being infected with H5N1, and as long as they are highly pathogenic Influenza is highly pathogenic to chickens.

Golden City said that it is currently monitoring poultry farms in Yilan, Hualien, and the west coast. As for the possible transmission route, it is speculated that migratory birds mix together in Siberia in summer, and bring bird flu into the wintering areas during autumn and winter migration. As for how to spread Into the duck breeding farm, firstly, migratory birds directly contacted the breeding duck farm, and secondly, migratory birds discharged waste in the pond. As a result, egrets, sparrows, etc. were infected and then went to the duck breeding farm. The current measures in the island are only Cull all the way.

Jincheng said that many of the poultry houses on the island are still open-type breeding, and it is difficult to isolate them from wild birds and waterfowl. Unless they are all indoor closed-type breeding, it is possible. Next year, Taiwan’s agricultural department will apply for funding from Taiwan’s administrative agencies Poultry houses need to be improved, but most waterfowl farmers are unwilling to keep birds indoors. This is the part that needs to be actively communicated.

Newsletter/H5N1 bird flu was found in 3 domestic duck farms and wild bird steak
2022/12/07 16:25:00
Life Center / Reported by Lai Junyou


The Agricultural Committee of the Executive Yuan held a press conference today (7) to explain that the Animal Health Office notified that the H5N1 subtype of highly pathogenic avian influenza was detected in the meat duck farm in Luzhu District, Kaohsiung City, the meat duck farm in Guantian District, Tainan City, and the wild bird row. HPAI) virus, the Council of Agriculture continued to strengthen various epidemic prevention measures for bird flu, and made every effort to prevent the spread of new viruses. This year, 3 domestic poultry farms were diagnosed with H5N1 subtype HPAI, and 3 cases of H5N1 subtype HPAI were detected in migratory (wild) birds.

The Council of Agriculture pointed out that according to the virus nucleic acid analysis of the Animal Health Institute, the H5N1 avian influenza case of breeding ducks in Wujie Township, Yilan County, the H5 and N1 sequences were compared with the wild birds and poultry 2.3.4.4b of the Eurasian region from 110 to 111 under the gene bank The branch H5N1 virus is the most similar, and the newly detected meat duck in Luzhu District, Kaohsiung City, the meat duck in Guantian District, Tainan City, and the H5N1 avian influenza virus detected in the Anatidae herd are closer to Yilan relatives. H5N1 avian influenza was detected in the relics of Anracidae from Yuli Township, Hualien County and the relics from Sicaoracidae from Tainan City, and its H5 and N1 sequences were compared with those of wild birds and poultry in Japan, China and Korea from 110 to 111 in 2.3.4.4 The b clade H5N1 viruses are most closely related. These viruses are of avian origin and cannot replicate well in mammalian cells.

According to the Council of Agriculture, most experts believe that this wave of highly pathogenic avian influenza epidemics worldwide is very serious and is one of the main reasons for the rapid spread of the epidemic through the migration of migratory birds. It has occurred again since October this year in countries upstream of my country's migratory bird routes (South Korea and Japan) Highly pathogenic poultry influenza outbreaks, of which 32 poultry farms in South Korea (from October 17 to today) have confirmed H5N1 subtype highly pathogenic avian influenza virus (branch b), and Japan (from October 28 to today) has 31 H5N1 subtype highly pathogenic avian influenza virus (both branch b) was confirmed in the poultry farm. Taiwan is a place where migratory birds must pass through the winter. The number of observations of migratory birds arriving in Taiwan in November this year was 1,865, an increase of 216.6% compared to 589 in October.

The Council of Agriculture pointed out that currently 3 duck farms in China have been diagnosed with H5N1 subtype HPAI. In order to effectively prevent the spread of the pathogen, in addition to the annual, autumn and winter avian influenza monitoring work and the expansion of the monitoring range of poultry farms around H5N1 subtype HPAI case farms, the density of duck farms has also been increased. Wetland wild birds and the surrounding environment of duck farms under the jurisdiction of counties and cities are monitored to facilitate early detection of viruses and immediate disposal. In addition, the frequency of disinfection in the public areas of the case farms will also be increased, and the Duck Farming Association of the Republic of China will be asked to supervise the members of the counties and cities with dense duck farms to strengthen the disinfection work in the duck farms.

The Council of Agriculture once again 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 kinds of vehicles, cages, appliances, etc. must be thoroughly disinfected when entering and exiting, so as to improve the self-epidemic function of the venue, effectively prevent the spread of bird flu through different media, and reduce the risk of new virus invasion and spread.

The Yunlin County Animal and Plant Epidemic Prevention Institute pointed out that the pathogen of bird flu that occurred in Yilan on the 20th of last month was H5N1, which is the same as the serotype circulating in South Korea and Japan this year. The pathogen found in Shuilin this time is also H5N1. , Kaohsiung, and the fourth positive field, it was determined that the outbreak was related to the spread of wild birds.

The Yunlin County Animal and Plant Epidemic Prevention Institute stated that the meat duck farm in Shuilin Township was found to be infected only after the epidemic prevention office sent staff to screen and screen. Today, the meat ducks that had only been raised for 20 days were culled, and a total of 25,637 ducks were culled. At the same time, a 5-kilometer radius was monitored. More than 60 poultry farms in the country are waiting for further results, as long as there are positive reactions, they will be culled immediately.

According to Yunlin County Animal and Plant Epidemic Prevention, the meat duck farm in Gukeng Township was infected with H5N2 last month, but this time the Shuilin meat duck farm was infected with H5N1, the two are different.

The Epidemic Prevention Office reminds the poultry industry that it is currently a high-risk period for bird flu. Farmers wear masks to prevent Covid-19, and don’t forget to strengthen the erection and integrity of bird-proof nets, help poultry farms wear masks, and find If the poultry is sick, notify the epidemic prevention agency as soon as possible, disinfect frequently, and do all the epidemic prevention work.

/Taipei real-time report


The bird flu epidemic is expanding again. The Bureau of Prevention and Inspection of the Council of Agriculture announced today that 5 poultry farms in Changhua were infected with N5N1 highly pathogenic avian influenza virus, including chickens, ducks, and geese .

Although the Bureau of Defense Inspection has tested the previous infection cases, the viruses are all avian-origin viruses, and their ability to replicate in mammalian cells is not good, but they still cannot be taken lightly.

Notified poultry farms in Changhua, including 1 red-feathered native chicken farm in Erlin Township, Changhua County, 1 black-feathered native chicken farm in Zhutang Township, 1 mixed breeding farm of Huang Jinji and black-feathered native chickens (the above 3 farms were actively notified), 1 native chicken farm Duck farm and 1 meat goose farm in Puxin Township (the above 2 farms are active monitoring).

The Bureau of Defense Inspection stated that 7,775 red-feathered chickens (6 weeks old), 11,257 black-feathered chickens (6 weeks old), 9,879 golden chickens (6 weeks old), and 839 native ducks (10 weeks old) were culled. ), 2015 meat geese (6 weeks old) were culled and destroyed in 5 rounds, and the cleaning and disinfection work of the field was completed.

H5N1 subtype highly pathogenic avian influenza (HPAI) virus has been detected since the Yilan Duck Center, the meat duck farm in Luzhu District, Kaohsiung City, the meat duck farm in Guantian District, Tainan City, and wild birds; H5N1 highly pathogenic avian influenza expanded to 11 farms, including 3 land poultry farms, 6 duck farms, and 2 goose farms.

Bird flu strikes five more farms
VIRAL SPREAD: The latest outbreak has so far affected 39 farms, including 25 chicken farms, 10 duck farms and four goose farms, the Council of Agriculture said
By Yang Yuan-ting and Jonathan Chin / Staff reporter, with staff writer
Sat, Dec 24, 2022 page2

The H5N1 avian influenza virus has been found in five more poultry farms, extending an outbreak that marks the first time the strain has made the leap from waterfowl to farmed landfowl in Taiwan, the Council of Agriculture (COA) said yesterday.

The infection clusters were found in one duck and three free-range chicken farms in Erlin Township (二林), and one goose farm in Pusin Township (埔心), all in Changhua County, COA Deputy Minister Huang Chin-cheng (黃金城) said.

The rise in cases shows that avian flu is spreading in Taiwan, although outbreaks have been contained, he said.

Authorities have ruled out the possibility that the latest H5N1 cases were transmitted from a previous cluster in Yilan County, and wild waterfowl remains the most likely vector, Huang said.

The vector for the outbreak in chicken farms was either virus-bearing wild birds that entered the farms through gaps in coop netting or poultry workers who were exposed to the pathogen, he said.

The chicken-raising Erlin and Jhutang (竹塘) townships in Changhua County were flagged as hot zones for increased monitoring and sterilization, he added...

Lin Jingjia
/Changhua real-time report


A new type of H5N1 bird flu outbreak broke out in Changhua County . A laying hen farm in Zhutang and a meat duck farm in Fangyuan were diagnosed with H5N1 by the National Health Service on the 28th and 29th of this month respectively. Duck farms in urban and rural areas were also confirmed to be infected with H5N2. Four poultry farms completed culling and disinfection in the past two days, and a total of 42,000 laying hens and ducks were culled. Since mid-December, there have been 7 H5N1 subtype high pathogenicity outbreaks in Changhua. The epidemic situation of poultry influenza is the largest in the counties and cities in China.

Changhua County is the largest poultry-raising county in Taiwan. It is mainly distributed in towns in the southwest corner. Since December, poultry farms have been infected with the highly pathogenic avian influenza virus H5N1. The Council of Agriculture has listed Puxin and Zhutang as high-risk areas. The county has initiated stricter biological epidemic prevention measures than the central government.

Dong Mengzhi, director of the Changhua County Animal Epidemic Prevention Institute, said that 2 of the 4 poultry farms are located in Zhutang Township, about 1 km away. The H5N1 epidemic is severe. As long as there is a confirmed poultry farm, the surrounding 1 km will actively sample and monitor. Nearly a hundred fields have been sampled, and it is expected to recover after the Lunar New Year to see if the H5N1 virus can gradually disappear.

Dong Mengzhi said that on December 26 and 27 of this year, the laying hen farms in Zhutang Township reported the abnormal death of chickens in their farms. The epidemic prevention station immediately sent personnel to carry out movement control and sent sick chickens to the Animal Health Office for inspection. 28 On the 29th and 31st, the domestic health center confirmed that they were infected with the new H5N1 and H5N2 subtype highly pathogenic avian influenza virus respectively. 33,886 laying hens.

Another meat duck farm in Dacheng Township and Fangyuan Township each found infection under environmental sampling and monitoring on the 25th. On the 29th, the National Health Service confirmed that they were H5N2 and H5N1 subtypes of highly pathogenic avian influenza virus. On the 30th, the epidemic prevention personnel completed the culling, cleaning and disinfection work of the two meat duck farms, and culled 9002 meat ducks.

Dong Mengzhi said that in the face of invisible enemies, the industry must be cautious, continue to strengthen inspections and implement various biosecurity measures in the venue, strengthen the disinfection of the venue, and strictly prohibit all types of vehicles and personnel from entering the venue. When entering the venue, personnel need to be asked to change clothes and shoes, and vehicles can only be entered after thorough disinfection.

Today (29) In Changhua, another quail farm was confirmed to be infected with the new H5N1 subtype highly pathogenic avian influenza virus, and 103,125 quails were culled. In the past 30 days, the county has won the bid for the fourth quail farm, and a total of 220,000 quails have been culled. 8544 quail.

The Changhua Animal Defense Institute stated that since the outbreak of the dart in the first native chicken farm on the 3rd of this year, it was reported that the laying hen farm and the quail farm had fallen. In case of abnormal death, the Epidemic Prevention Institute immediately dispatched personnel to carry out movement control and take samples to the Animal Health Office for inspection. On the 27th, the Home Health Institute confirmed the infection of the new H5N1 subtype highly pathogenic avian influenza virus. The quail farm was culled, cleared and disinfected.

In this regard, the Changhua Animal Defense Institute pointed out that quail eggs are "bird eggs" sold in general night markets. Because quails are small in size and intensively reared, it is even more necessary to take epidemic prevention measures. However, since there have been no cases of bird flu infection in quails in the county in the past, The focus of the publicity is on land and water birds. Quail owners are prone to neglect and fail to take the necessary protective measures, and are easily infected by migratory birds.

In addition, the Changhua Animal Defense Institute also reminded that if a poultry farm is inspected and fails to take preventive measures in accordance with the regulations, it can impose a fine of up to 150,000 yuan and make improvements within a time limit.
