Bird flu virus has been detected on a farm in Denmark's central Fyn island, Xinhua quoted country's veterinary department as announcing. Some 2,000 chickens on the farm in Stenstrup on the island will be culled Tuesday to contain the spread of the disease, the Danish Veterinary and Food Administration said in a statement . Initial checks show that the virus detected is not the deadly H5N1 strain that has ravaged Southeast Asia over the past two years. Denmark was earlier struck by avian influenza in 2006.
