Korean officials have confirmed an outbreak of avian influenza in the southern part of the country, in the nation's first case of the virus since 2011.
The Ministry of Agriculture, Food and Rural Affairs said Friday it had confirmed the presence of the H5N1 virus in poultry at a farm in Gochang, Jeollabuk-do.
The AI case was first reported on Thursday, prompting provincial authorities to cull all 20-thousand ducks there, and access to the area has been restricted.
Farms in other provinces that have recently bought ducks from the Gochang farm are also taking precautionary measures against the virus.
Korea's last avian influenza outbreak resulted in the culling of 3 million birds in 2011.
