THE farm at the centre of the latest bird flu outbreak was named today as Witford Lodge Farm at Hockering, Norfolk.
Police officers stood guard at the entrance to the farm after a number of dead chickens tested positive for the virus.
All of the 35,000 chickens at the farm will now be slaughtered, as measures are put in place to prevent the spread of the virus.
Tests are being carried out today to establish the exact strain of the virus but preliminary tests show that it was likely to be the H7 strain rather than H5N1. The latter has been responsible for the deaths of more than 100 people, mainly in Asia.
Last month a wild swan that was found dead in the harbour of a coastal town in Scotland was found to have died of avian flu.
That bird, which was discovered in Cellardyke, Fife, tested positive for the deadly H5N1 version of the virus.
Although hundreds of wild birds have been tested in the last few months, the swan in Fife remains the only case of H5N1 to have been discovered in the UK.
While H7 versions of the disease can be highly pathogenic among poultry, and have crossed the species barrier to humans, outbreaks in people have been less serious than those of H5N1.
Some experts fear the H5N1 virus could mutate and develop into a flu pandemic which could put millions of lives at risk.
