Avian Influenza found in poultry farm in Norfolk

Preliminary tests have this evening indicated that the avian influenza virus is present in samples from chickens found dead on a poultry farm near Dereham in Norfolk.

Further tests are being carried out to determine the strain of the virus and more will be known tomorrow. The preliminary test results show that it is likely to be the H7 strain of avian influenza, and not H5N1. Further confirmatory tests are in progress to determine the pathogenicity.

As a precautionary measure birds on the premises will be slaughtered on suspicion of an avian notifiable disease. Restrictions have been placed on the farm. When the additional laboratory results are known further action may be taken.
