South Korea is bolstering its defenses against a potential outbreak of highly pathogenic avian influenza (HPAI), commonly known as bird flu. The announcement follows the confirmation of the virus in fecal samples collected from wild birds along the Mangyeong River in Gunsan City, Jeollabuk Province, on October 27th.
This finding marks the first documented instance of HPAI in Korea during the current winter season, raising concerns as migratory bird populations begin their seasonal influx. The arrival of these birds significantly increases the risk of spreading the virus to domestic poultry.
Enhanced Quarantine Measures Underway
In response to the escalating threat, Gyeongsangnam-do Province has initiated intensified quarantine protocols. Starting November 3rd, a two-week inspection period will focus on six key cities and counties – Changwon, Sacheon, Gimhae, Yangsan, Goseong, and Changnyeong – all situated within major migratory bird habitats.
These inspections will verify the implementation of existing quarantine rules and assess the effectiveness of disinfection facilities installed at farms located near these critical habitats. Authorities are notably focused on ensuring farm owners are adhering to preventative measures.
Prior Preventative Actions
Previous efforts to contain the spread of the virus included designating 12 major migratory bird habitats within Gyeongnam Province as “livestock vehicle access control zones” as of september 22nd. This directive prohibited the entry of livestock transport and personnel into these sensitive areas. Furthermore, an administrative order was issued banning free-range farming practices across all poultry operations in the province.
Daily disinfection operations are currently being conducted by 86 joint pest control teams and 37 city/county disinfection vehicles targeting migratory bird habitats and nearby waterways.
Essential Biosecurity Protocols for Poultry Farms
Poultry farms are urged to implement crucial biosecurity measures to safeguard their flocks. These guidelines include installing protective netting to deter wild animals, sealing any gaps in barn structures, daily disinfection of farm premises, and a two-stage vehicle disinfection process upon entry. Farmers are also required to change into dedicated clothing and footwear when entering barns.
Jeong Chang-geun, the head of the Animal Quarantine Department of Gyeongsangnam-do province, noted a recent survey conducted by the Ministry of Climate, Energy and Habitat estimates approximately 20,000 migratory birds are currently in the province, with numbers expected to rise throughout November. He emphasized the critical importance of heightened vigilance and stringent biosecurity practices among livestock farmers.

Understanding Avian Influenza
Avian influenza viruses are naturally occurring in wild aquatic birds worldwide and can infect domestic poultry and other bird and animal species.Different strains vary in pathogenicity, with highly pathogenic avian influenza (HPAI) causing severe illness and high mortality rates in poultry. The virus is spread through direct contact with infected birds, contaminated surfaces, and airborne particles.
ongoing surveillance and rapid response are crucial for controlling HPAI outbreaks and mitigating their economic and public health consequences. The United states Department of Agriculture (USDA) provides detailed facts about avian influenza, including current outbreak updates and biosecurity resources. USDA Avian Influenza Information

What are the potential economic consequences of an avian influenza outbreak in Gyeongnam Province, considering past outbreaks in South Korea?
Gyeongnam Province Detects AI Virus in Winter Migratory Birds at Mangyeong River, Heightens Quarantine Measures
Avian Influenza Outbreak: Current Situation in Gyeongnam
On october 30, 2025, Gyeongnam Province officials confirmed the detection of the Highly Pathogenic Avian Influenza (HPAI), commonly known as bird flu, in wild bird samples collected near the Mangyeong River. This revelation triggers immediate and stringent avian influenza control measures to prevent potential outbreaks in poultry farms and minimize economic impact. the identified strain is currently under genomic sequencing to determine its specific characteristics and potential for transmission. This incident underscores the ongoing risk posed by migratory birds as carriers of avian influenza viruses.
Location and Species Affected
The initial detection occurred in samples taken from fecal matter of wild birds inhabiting the ecological zone surrounding the Mangyeong River, specifically within Changnyeong County, gyeongnam Province. The affected species are primarily ducks and geese, common winter visitors to the Korean peninsula. These birds are known to be asymptomatic carriers of the AI virus, meaning they can spread the disease without showing visible signs of illness.
* Confirmed Species: mallards, bean Geese, and Greylag geese.
* Geographic focus: Mangyeong River basin,Changnyeong County,Gyeongnam Province.
* Monitoring Expansion: Surveillance is being expanded to adjacent areas including haman County and Sancheong County.
Quarantine and Control Measures Implemented
Gyeongnam Province has activated its emergency response plan, implementing a multi-faceted approach to contain the avian influenza outbreak. Key measures include:
- movement Restrictions: A 10km radius control zone has been established around the detection site. Movement of poultry, poultry products (eggs, meat, feed), and related equipment within this zone is strictly prohibited.
- Farm biosecurity Enhancement: poultry farmers within the control zone are mandated to implement enhanced biosecurity protocols. this includes:
* Disinfection of vehicles and personnel entering and exiting farms.
* Restricting access to farm premises.
* Providing clean feed and water.
* Regular health monitoring of poultry flocks.
- Wild Bird Monitoring: Increased surveillance of wild bird populations is underway, with intensified sampling and testing efforts focused on key migratory routes and wetland areas.
- Public Awareness Campaign: A public awareness campaign is being launched to educate residents about the risks of avian influenza and the importance of reporting any suspected cases of sick or dead birds.
- culling Considerations: While not currently implemented, preemptive culling of poultry within the control zone remains a possibility if the virus spreads to domestic flocks.
Impact on Poultry Industry & Economic Concerns
South Korea’s poultry industry is highly susceptible to the economic consequences of avian influenza. Past outbreaks have resulted in the culling of millions of birds, leading to notable financial losses for farmers and disruptions in the supply chain. The current situation is being closely monitored to assess the potential impact on poultry prices and availability.
* Previous Outbreaks: South Korea experienced major AI outbreaks in 2016-2017, 2018, and 2020-2021, resulting in the culling of over 30 million birds.
* economic Impact: Outbreaks lead to increased poultry prices, reduced exports, and financial hardship for poultry farmers.
* Government Support: The South Korean government provides financial compensation to farmers whose birds are culled as part of disease control efforts.
