About 700 ducks have been culled following the discovery of an outbreak of bird flu in the southern Vietnamese province of Ca Mau.
Duong Van Khoa, head of Tran Van Thoi District Veterinary Station, said many ducks had died last Thursday from the symptoms of bird flu.
On Monday, tests confirmed that the birds were positive for the H5N1 strain. The entire flock was culled and decontaminants were sprayed on the surrounding area.
This is the first bird flu outbreak to occur this year in Ca Mau Province.
