Over 11,000 poultry infected with the H5N1 virus were disposed of in the Krong Ana River of the Highlands province of Dak Lak.
Medical workers are severely worried about the environmental pollution and the spread of disease this may cause.
Despite full vaccination, my water-fowl are under the threat of infection, said farmer Vu Dinh Bay of Son Tra Village, Binh Hoa Commune.
Veterinarians fished out ten bags of dead water-fowl from the river already, said Vo Van Nam, chair of the Department of Agriculture and Rural Development.
The People’s Committee of Dak Lak will purchase 800,000 vaccinations for all of the poultry in the province.
