More than 300 nature reserves, parks and reservoirs are being
added to the list of sites where wild birds are tested for signs
of avian influenza, Environment Secretary David Miliband announced
The sites, owned by wildlife groups, local authorities and private
companies, will be patrolled by their staff who will report dead
water birds to Defra - enhancing national surveillance of the wild
Mr Miliband was visiting an organic goose farm in Sandy, Bedfordshire
and the headquarters of the Royal Society for the Protection of
Birds, one of the partners joining the wild bird survey.
“This will greatly increase the scope of our surveillance
and add to our understanding of the disease risk. There is no reason
to think that any dead birds found at these sites are more likely
to have died of avian flu but this is a highly efficient way to
sample more wild birds and to target our work effectively.
“This initiative means we are also building more long-term
working partnerships with conservation groups, local communities
and private industry across the country. Together we may limit
the risk of highly-pathogenic avian influenza.”
The extra surveillance sites comprise more than 1,200 square kilometres.
They will complement the targeted strategy for detecting high-pathogenic
avian flu which was launched by Defra and the devolved administrations
in September and which includes testing of live birds, dead birds
and those shot during sports shooting.
There is also a domestic poultry survey which has been testing
a sample of farmed birds since 2003. Any suspicion of avian influenza
in farmed birds is investigated by Defra and the SVS immediately.
1. 304 new sites have become official wild bird survey sites.
Dead birds of certain target species found at these sites will
be reported to the Defra helpline and a selection collected by
the State Veterinary Service for testing.
2. The UK's first survey for avian influenza in wild birds began
last October after the European Union advised all member states
to enhance surveillance of wild birds after the virus gradually
3. Thousands of samples have been tested but there has so far
only been one case of highly pathogenic H5N1 detected in a sample
from a dead swan found at Cellardyke in Scotland in April. It is
normal for a proportion of wild birds to carry low pathogenic avian
influenza viruses so it would not be unusual to detect some LPAI
viruses over the course of the survey. These are normally of little
significance to human or animal health.
