South Korea has confirmed a second case of African swine fever near its border with North Korea, raising concerns that the outbreak could spread and wreak havoc on the country's massive pig herds.
An official from South Korea's agriculture ministry said on Wednesday that workers were planning to cull some 5,000 pigs raised at a farm in the town of Yeoncheon after the highly contagious disease was confirmed in tests of a dead pig.
Officials culled nearly 4,000 pigs and stepped up quarantine efforts on Tuesday after confirming the country's first case of the disease.
African swine fever has decimated pig herds in China and other Asian countries before reaching the Koreas.
It is harmless to people but for pigs is highly contagious and fatal.
There is no known cure.
