(Seoul = Yonhap News) Reporter Shin Seon-mi = The Central Disaster and Safety Countermeasures Headquarters for Highly Pathogenic Avian Influenza (AI) announced on the 5th that highly pathogenic AI of the H5N1 type occurred at a laying hen farm in Asan, South Chungcheong Province, and a meat duck farm in Cheongju, North Chungcheong Province.

This brings the total number of highly pathogenic AI cases that occurred at poultry farms nationwide during the 2024-2025 epidemic period to 46.

A farm in Asan was raising 68,000 chickens, and a farm in Cheongju was raising 13,000 ducks.

The Central Disaster and Safety Countermeasures Headquarters is sending initial response teams to each farm to control access, cull, and conduct epidemiological investigations.

The central government will conduct a thorough inspection of poultry farms (40 in Asan and 29 in Cheongju) within quarantine areas and farms and facilities where visitors and vehicles from outbreak farms entered in order to prevent the spread of AI and detect infected individuals early.

In addition, the period until the 11th has been designated as a 'nationwide simultaneous disinfection week' and livestock facilities and vehicles will be disinfected.

Highly pathogenic avian influenza confirmed at native chicken farm in Asan, South Chungcheong Province
Reporter Name Reporter Hong Jeong-min Posted 2025.04.21 11:17


Quarantine measures will be strengthened following the confirmation of highly pathogenic avian influenza at a native chicken farm in Asan, South Chungcheong Province.

The Central Disaster and Safety Countermeasures Headquarters (Headquarters Director Song Mei-ryeong, Minister of Agriculture, Food and Rural Affairs, hereinafter referred to as the Central Disaster and Safety Countermeasures Headquarters) held a meeting on the 20th to inspect quarantine measures and strengthen quarantine measures such as 1:1 dedicated management of quarantine teams at farms, and designation and operation of a ‘nationwide simultaneous disinfection and deportation week’ from the 21st to the 27th.

# Occurrence situation

On the 19th, the owner of a native chicken farm in Asan-si, Chungcheongnam-do reported to the quarantine agency due to an increase in deaths, and on the 20th, a detailed inspection confirmed highly pathogenic avian influenza (H5N1 type). This is the 47th case since the first occurrence on October 29th of last year. The highly pathogenic avian influenza occurrences include 29 cases of chicken (22 laying hens, 4 native chickens, 2 meat breeding hens, 1 laying breeding hens) and 18 cases of ducks (16 meat ducks, 2 breeding ducks).

Since the 8th of last month, 6 cases have been concentrated in the Cheonan-Asan area of Chungcheongnam-do, and considering the situation where additional outbreaks continue at farms within the quarantine area, it is presumed that the virus remains in the area, and quarantine management such as disinfection and access control is necessary to prevent sporadic outbreaks.

# Quarantine measures

Since the H5 antigen was confirmed at a native chicken farm in Asan-si, Chungcheongnam-do, the Central Disaster and Safety Countermeasure Headquarters immediately dispatched an initial response team in accordance with the ‘Avian Influenza Emergency Action Guidelines (SOP)’ to control access and conduct epidemiological investigations, including culling laying hens at the outbreak farm to prevent further spread.

In addition, in order to block the spread of highly pathogenic avian influenza, a temporary standstill order was issued for 24 hours from midnight on the 19th to midnight on the 20th for chicken farms and related livestock facilities such as slaughterhouses and livestock vehicles in the entire Chungcheongnam-do and Pyeongtaek-si, Gyeonggi-do, and the compliance status was checked.

In addition, a detailed inspection was conducted on poultry farms (No. 45) within the quarantine zone (~10km) of the outbreak farm, and available disinfection resources were deployed to disinfect roads around migratory bird habitats, small streams, and reservoirs, and access roads to poultry farms.

# Strengthening quarantine measures

The Central Disaster and Safety Countermeasure Headquarters will strengthen quarantine measures as follows to manage quarantine in the outbreak area and prevent sporadic outbreaks and spread of highly pathogenic avian influenza.

First, a comprehensive inspection will be conducted on all native chicken farms (43 farms) in Chungcheongnam-do, the outbreak area, and a detailed inspection and quarantine inspection will be conducted on farms in the same group (6 farms; 1 in Gyeonggi, 2 in Chungcheongnam-do, 3 in Jeollabuk-do) from the 21st to the 30th. In addition, a dedicated officer will be assigned to each poultry farm (45 farms) within the Asan quarantine area (10km) to closely manage on-site quarantine measures such as disinfection of external vehicles and personnel entering and exiting.

Second, in order to eliminate residual viruses, the period from the 21st to the 27th will be designated as the ‘National Disinfection and Guseo (驅鼠) Week’ and intensive disinfection will be carried out in cooperation with producer groups. In particular, the Chungnam region will mobilize the wide-area disinfection equipment and drones from the Livestock Quarantine Support Headquarters to intensively disinfect roads with heavy livestock vehicle traffic and livestock shed roofs in densely populated areas, and poultry farms will disinfect the inside and outside of their farms on their own daily basis.

Third, we will strengthen the detailed inspection of native chickens shipped to slaughterhouses nationwide, and operate a ‘day of total closure and disinfection’ every Wednesday for traditional markets nationwide (139 locations) to check the implementation status until the nationwide movement restrictions are lifted by each local government.

Fourth, we will dispatch a special quarantine team for avian influenza composed of section chiefs from the National Institute of Animal Quarantine to three regions in Chungnam Province, Cheonan, Asan, and Sejong, where sporadic outbreaks are a concern, to provide quarantine technical support and guidance.

Choi Jeong-rok, Director of the Quarantine Policy Bureau of the Ministry of Agriculture, Food and Rural Affairs, said, “Six cases of highly pathogenic avian influenza have occurred in the Cheonan-Asan area of South Chungcheong Province since March,” and added, “Most winter migratory birds have moved north, but some populations have not yet moved north and remain, and in certain areas, the local environment itself is already contaminated with the virus, so farms that do not follow basic quarantine rules such as disinfecting vehicles and personnel entering and exiting, and changing boots can cause outbreaks at any time. Therefore, each local government should thoroughly inspect high-risk areas such as densely populated egg laying complexes, manage vehicles entering and exiting, and thoroughly check that there are no gaps in quarantine management by region and farm.” He also emphasized, “Since we plan to operate a ‘nationwide simultaneous disinfection and sanitation week’ from the 21st to the 27th to eliminate residual viruses, local governments should mobilize all available disinfection resources to thoroughly disinfect roads around migratory bird arrival areas and reservoirs, as well as farm access roads, and guide and inspect livestock farms to disinfect the inside and outside of their farms every day and perform sanitation work.”
