Tainan chicken farm infected with H5N1 bird flu, 11,449 native chickens culled

Bird flu was reported at a local chicken farm in Madou, Tainan. The Nan City Animal Protection Office completed the culling and disinfection of chickens today and is closely monitoring the follow-up situation. Photo/Provided by Nanshi Agriculture Bureau

The Animal Protection Department of Nanshi City recently received a report from a local chicken farm in Madou District that the chickens in the farm were dying abnormally. On the same day, they sent personnel to conduct epidemic investigation and movement control. After sampling and testing, they were confirmed to be highly pathogenic of the H5N1 subtype. To prevent the spread of bird flu, the Animal Welfare Department culled all 11,449 native chickens in the site today, transported them to the incinerator for destruction, and disinfected the entire site to prevent the spread of the disease.

The Animal Welfare Department stated that sampling and monitoring will be implemented at 15 poultry farms within a radius of 1 kilometer around the native chicken farm, and 66 poultry farms within 1 to 3 kilometers will be visited and inspected. Sampling and monitoring of related farms of case poultry farms will be implemented to simultaneously strengthen Control the abnormal number of deaths in chemical manufacturing plants, inspect the cleaning and disinfection of chemical manufacturing vehicles, and strengthen the frequency of disinfection of surrounding public areas to minimize the amount of viruses in the environment.

The Animal Welfare Department pointed out that the global avian influenza epidemic is approaching fiercely. Cases of highly pathogenic avian influenza have been found in poultry farms and in migratory birds in countries upstream of migratory bird routes. Most winter migratory birds have arrived in Taiwan, and there is also the H5N1 subtype in China. Cases of highly pathogenic avian influenza in poultry farms and migratory (wild) birds show that the current risk of invasion by overseas avian influenza viruses is quite high.

The Animal Welfare Department stated that due to the recent cold wave, low temperature and humidity can easily cause cold stress, leading to a decrease in the immunity of poultry. Poultry farmers are reminded to do a good job in cold insulation and strengthen epidemic prevention work, and strictly control people and vehicles. Personnel, vehicles (including transporting poultry) Vehicles, egg trucks, chemical trucks, feed trucks, etc.), transportation vehicles (transport cages, egg boxes, egg trays, etc.) and equipment entering and exiting should be thoroughly disinfected, and holes in the bird-proof fence of the poultry house should be repaired to prevent poultry from being exposed to the virus. Contact with migratory (wild) birds reduces the chance of virus invasion.

The Animal Welfare Department calls on poultry farmers who find that poultry on the farm have symptoms such as depression, loss of appetite, decreased egg production, or abnormal death, they should immediately report it to the Animal Welfare Department and take necessary measures according to the guidance of epidemic prevention personnel...
