Local authorities in Vietnam\'s Central Highlands Dak Lak province instructed destroying a flock of more than 1,300 ducks and 9,800 duck eggs due to their infection to the avian influenza H5N1, reported the local Agriculture and Rural Development Department on Tuesday.According to the report, the poultry were raised by Vo Thanh Son and his family in Ea Nuol commune, Buon Don district. Relevant agencies joined hands by applying sanitation measures to sterilize the farm and surrounding areas, as well as closely monitored the epidemic progress.A local report said that earlier this month, a farmer from Buon Ma Thuot City (Dak Lak province) found signs of the disease, but he did not inform the local agency, resulting in the death of over 5,000 ducks, which he had to destroy them himself. Vo Thanh Son brought home 23 living ducks from the flock and raised them in his farm, causing the re-break of the disease in his location.The local authorities alerted relevant agencies and localities of the disease expansion unless timely measures are applied properly.
