With numerous cases of avian influenza(AI) confirmed, the number of culled chickens has topped two million.

The Ministry of Agriculture, Food and Rural Affairs said it investigated three poultry farms over the past five days and confirmed that farms located in Anseong and Icheon, both in Gyeonggi Province, were affected by the highly pathogenic H5N6 strain of bird flu.

Nearly 400-thousand chickens were culled from those three farms alone.

As of Friday, 46 farms in 13 cities and counties in five provinces were found to have been infected with bird flu.
