South Korea has reported its first case of African swine fever in a year.
The disease is not harmful to humans, but almost always, fatal to pigs.
According to the agriculture ministry, three pigs were found dead on Thursday at a farm in Gangwon-do Province and were later confirmed to have been infected.
From early Friday, a 48-hour travel ban has been issued for livestock facilities, such as pig farms and slaughterhouses, in Gyeonggi-do and Gangwon-do Province.
Authorities also plan to cull more than two-thousand pigs, including those within a 10-kilometer radius of the infected farm.
Last October, an outbreak of African swine fever prompted the country to cull about 400-thousand pigs and caused volatility in pork market.
