Outbreak in Muan Raises Concerns Over Rapid Spread
South Korea is grappling with a resurgence of foot-and-mouth disease (FMD), this time affecting swine populations in Jeonnam province. This marks the first instance of the disease in pigs in the region and the first nationwide in seven years, raising concerns about potential economic repercussions for the pork industry.
the outbreak was confirmed on April 11th at two pig farms in Muan, Jeonnam. These farms are located in proximity to a cattle farm where FMD was detected last month.During routine testing within a 10km radius of the initial outbreak, the virus was discovered on the affected pig farms, with 12 animals testing positive.
What sets this outbreak apart is the significantly higher viral load associated with FMD in pigs compared to cattle. Pigs can emit between 1,000 to 3,000 times more virus than cattle,making them a potent source of transmission. Muan, the epicenter of this outbreak, is a major pork-producing region, housing over 24,100 pigs across 75 farms, representing a ample portion of Jeonnam’s pig population.
Immediate Culling and Containment Measures
In response to the outbreak, authorities have implemented emergency protocols, including the culling of all 5,470 pigs on the affected farms to prevent further spread. A temporary standstill order has been issued for livestock farms and vehicles within a 3km radius of the affected area, restricting movement to contain the virus.
Vaccination Challenges and “Breakthrough Infections”
Compounding the situation is the fact that the affected farms had recently completed vaccination programs. The vaccine antibody positive rate at the affected farm was 98.4%, raising concerns about so-called breakthrough infections,
where vaccinated animals still contract the disease, potentially without showing symptoms. this asymptomatic infection poses a meaningful challenge to disease control efforts.
The foot-and-mouth disease virus is so light that there are many radio waves in the air.
Official Statement
Economic Impact and Regional Concerns
The outbreak has triggered heightened vigilance in surrounding areas, including Naju, Yeongam, Hampyeong, Mokpo, and Sinan, which collectively account for nearly half of Jeonnam’s pig farms and pig population. The potential for widespread economic disruption is significant, given the region’s reliance on pork production.
The declaration of the end of the foot -and -mouth disease, which was originally expected in mid -April, is expected to be possible in early May. The ending declaration is only possible only if the virus is not detected after three weeks after the last killing.
Preventative Measures and Future Outlook
Authorities are urging farmers to intensify biosecurity measures, including rigorous cleaning, disinfection, and restricted access to farms. The province is maintaining a high alert level in 10 cities and counties, with livestock market operations suspended. The initial expectation of declaring the end of the FMD outbreak by mid-April has been pushed back to early May, contingent on no further virus detection after three weeks from the last culling.
Daily cleaning, washing, and disinfection, and began to do not have to be blocked.
