Tests are being carried out for avian flu on a swan found dead in Fife, Scotland.

Defra said that preliminary tests had found the highly pathogenic H5 avian flu in a sample from the swan but the exact strain of the virus was not yet known.

A three kilometre protection zone and a ten kilometre surveillance zone has been set up around where the swan was found and bird keepers have been urged to isolate their birds from wild birds.

Chris Milne, chief veterinary officer for Scotland, said: “Whilst disease has yet to be confirmed, this is an important development. Bird keepers outside the protection zone should redouble their efforts to prepare for bringing their birds indoors if that becomes necessary.”
