DEFRA TEAMS UP WITH BIRD CONSERVATION GROUPS FOR AVIAN FLU SURVEY

A new survey of wild birds across the UK is being carried out to allow scientists to get a better picture of avian influenza viruses in waterbirds including H5N1, the virus similar to that  found in the Far East and Russia .

The survey builds on work carried out for the last three years to examine dead wild birds for the presence of a number of diseases.

Defra, which has a detailed contingency plan to limit the spread of and eradicate any potential outbreak of avian flu in poultry, has teamed up with ornithological and conservation groups to carry out the survey as part of a European-wide programme to monitor avian influenza viruses in wild birds.

The plan, agreed by the European Commission, comes after it was reported that wild bird populations may have been involved in the spread of avian flu from China and Mongolia to Eastern Russia .

The risk of high pathogenic avian influenza reaching the UK via migrating birds remains low but Defra is working closely with the RSPB, the British Trust for Ornithology,  the Wildfowl & Wetlands Trust and the British Association for Shooting and Conservation to monitor waterbirds for the infection.

The three-month programme involves taking samples from live birds caught in traps and nets, a small number of birds shot legally by wildfowlers and birds found dead - so-called die-offs.

The survey of die-offs will supplement on-going sampling work being done on a much larger range of wild birds for other avian diseases.

Most of the surveillance programme will be carried out by professional ornithologists who will take samples for analysis by scientists at the Veterinary Laboratories Agency, the European Community reference laboratory for avian influenza and the Agency which runs the Diseases of Wildlife Scheme for Defra.

Defra chief vet Debby Reynolds, said: "The risk of avian influenza spreading from eastern Russia to the UK via migrating birds is still low.

"However, we have said all along that we must remain on the look out for the disease. This surveillance programme is important to maintain vigilance.

"Most of the work will involve the staff of ornithological groups and we are very grateful for their invaluable expert advice and experience.  This is a new partnership for the Animal Health and Welfare Strategy, with the focus  on prevention better than cure.

"This survey of wild-caught birds and shot birds will last three months. It will give a better picture of the possible presence of an avian flu virus in waterbird populations.  Work will continue after this date to investigate die-offs in wild birds.

"The results will be submitted to the European Commission and analysed with  those produced by other member states in the New Year when it will then be decided what further work, if any, is necessary."

NOTES 

* There have been no reports of avian influenza A (H5N1) in wild or domestic birds in the UK so the risk of human infection from domestic or wild birds is extremely low. Avian influenza A (H5N1) is most commonly spread to humans through close contact with live and dead infected birds; the virus is shed in the faeces of such birds, so contact with faeces is a possible transmission route.

* The practice of thoroughly washing hands with soap and water (followed by drying) after contact with wild or domestic birds and ensuring any animal killed for meat is cooked thoroughly will help minimise the risk of infection from other diseases.

Birds will be sampled in Northern Ireland , England and Scotland .

* For more information about the survey contact partner organisations. Contacts details below:

* RSPB - Andre Farrar - 01767 - 681577

* BTO - Graham Appleton - 01842 - 750050

* BASC - Simon Clarke -  01244 - 573031

* WWT - Nicki Hayward - 01453 891175

* The species targeted include: Widgeon, Teal, Mallard, Pintail, Shoveler, Tufted Duck, Gadwall, Pochard and possibly Lapwing.

* Where shot birds are to be tested, only those that have already been legally shot in the course of coastal wildfowling will be included in the survey.

* The investigation of unusually high mortality events or 'die offs' in wild birds is a component of avian influenza surveillance.  These are characterized by deaths of an unusually high number of wild birds in relation to the population size in the area concerned.  Since 1998, Veterinary Laboratory Agency Regional Laboratories have been investigating the causes of these events by testing carcasses submitted by the general public.

* People who see unusually large groups of dead birds should call the usual Defra Helpline on 08459-335577.

* Callers will then be referred to the nearest Veterinary Laboratories Agency (VLA) regional laboratory or in Scotland the nearest Scottish Agricultural College (SAC) laboratory.

* Specialists at the labs will then make an assessment using the information on what further, if any action, should be taken.

* Out of hours calls will be automatically re-routed to Defra's duty office.
