A case of African swine fever (ASF) has been confirmed at a pig farm in Inje-gun, Gangwon-do, South Korea. One mother pig tested positive at the farm, leading to the confirmation of two additional cases. Authorities plan to cull 550 pigs from the farm and implement measures such as disinfection and movement control to prevent further outbreaks. The farm is located 10 km away from other pig farms. This outbreak reminds of a similar one in August that resulted in the culling of about 1,700 pigs.
