SEOUL, Dec. 30 (Yonhap) -- South Korea has confirmed a fresh case of avian influenza at a duck farm in the southwestern region, the agriculture ministry said Saturday, raising alarms in the major poultry production region already infected with highly pathogenic bird flu.

The H5N6-strain bird flu was detected on a farm with 35,000 ducks in Yeongam, 380 kilometers south of Seoul, while quarantine officials were conducting an inspection in the county, the Ministry of Agriculture, Food and Rural Affairs said.

It was located within 3 kilometers of another farm that reported the outbreak of a highly pathogenic strain on Dec. 19, which was put under restriction of movement of poultry, livestock breeders and equipment.
