South Korea quarantine officials have slaughtered more than 22.5 million poultry this winter, an official said, as part of intense efforts to contain a bird flu that has ravaged chicken farms across the country.

    They also plan to kill an additional 2.97 million chickens and ducks across the country in coming days, said Han Jae-hong, an official handling the issue at the Ministry of Agriculture, Food and Rural Affairs.

    That means the total number of poultry culled would account for about 15% of South Korea's poultry since November 16, when the first outbreak was reported at a chicken farm in Haenam, about 420 kilometers south of Seoul, South Korea's News Agency (Yonhap) reported.

    The outbreak, the first in nearly seven months, was caused by the highly pathogenic H5N6 strain of bird flu, a new type of virus that was first detected in South Korea. In April, quarantine officials slaughtered 12,000 chickens and ducks. 

    South Korea culled 14 million birds in 2014. South Korea has more than 156 million chickens and more than 9.5 million ducks as of the end of March.
