Preliminary testing of a common buzzard found dead on Lantau Island has indicated a suspected H5 avian flu case, the Agriculture, Fisheries & Conservation Department says.

Buzzards are a common winter visitor to Hong Kong. The carcass was found and collected on December 17 at Sha Lo Wan on Lantau. There are no chicken farms within 3km of where the bird was found.

The department will remind poultry farmers, pet bird shop owners, pet poultry and racing pigeon licence holders to enhance precautionary and biosecurity measures against bird flu.
