HONG KONG, Dec. 21 (UPI) -- Hong Kong health officials say they ordered the killing of more than 17,000 chickens after a carcass infected with bird flu was discovered at a poultry market.
The carcass was found to have a "highly pathogenic H5N1 avian influenza virus," York Chow, Hong Kong's secretary for food and health, said in a statement announcing the cull.
