Bird flu probe widens after 3 infected swans found in nature reserve owned by one of Britain's richest women


Thursday, Jan 11th 2018

Animal health experts are expected to begin inspecting a number of poultry farms today after three wild swans tested positive for the deadly H5N1 (should be H5N6, GvdH) strain of bird flu.

Restrictions on the movement of captive birds are in place following the discovery of the dead swans on the Abbotsbury Swannery, an open reserve in the Chesil Beach area of Dorset, during routine surveillance.

The Health Protection Agency (HPA) is monitoring about 12 staff at the reserve for signs of the disease, though the risk of infection is said to be low.

John Houston, general manager at Abbotsbury Tourism Ltd, said the birds were found by a member of staff at the swannery and Defra was notified as part of standard procedure."

Our main concern is the welfare of the swans, our staff and the general public," Mr Houston said.

"We are working closely with Defra to ensure that this outbreak is contained and that the number of swans affected is limited."
Mr Houston said the HPA had advised there was almost no risk of infection among swannery staff, but they had begun a course of Tamiflu tablets as a precaution.Three of the staff are full-time, while the others were identified as coming into contact with the swannery for different reasons, including deliveries.

The Department for the Environment, Food and Rural Affairs (Defra) has set up control and monitoring areas around the Abbotsbury site to try to contain the outbreak.

Severe movement restrictions apply within the zones, with bird owners only permitted to move their flocks under special licence from Defra.

The control area extends approximately 15 miles (25km) to the south-east of Abbotsbury, and includes the town of Weymouth, Chesil Beach and the Portland Bill headland, while the larger monitoring area of some 20 miles also covers the town of Dorchester.

Within the control and monitoring areas, bird gatherings such as poultry auctions and pigeon races are banned, and owners of poultry and other captive birds are required to house their flocks where possible.

Hunting wild birds and releasing game birds is also banned in protection zones.All commercial poultry premises in the area are to undergo inspection by Defra officials for signs of the disease.

Defra said that no disease has been found in domestic birds, and that there were no plans to cull wild flocks as this may disperse birds further.

Eighteen wild birds confirmed with bird flu in Dorset

The government has confirmed bird flu in 18 wild birds at Abbottsbury, Dorset ? 16 in mute swans, 1 Canada Goose and 1 Potchard Duck.

Defra, via the World Organisation for Animal Health (OIE), has confirmed High Path Avian Influenza in Abbotsbury Swannery, Dorset.

The virus H5N6 has been found in the birds. The strain, however, is the European strain, as opposed to the Asian strain, which is not associated with humans.

This strain has already been identified in dead wildfowl found recently in Holland and Germany.

This is the first case of HPAI in the UK this winter and, although Defra is not expected to raise the risk level for poultry, poultry keepers have been urged to raise vigilance and enhance biosecurity now that the virus is circulating in England.

Avian flu found in wild birds in Dorset


Bird flu confirmed in wild birds in the UK for first time this winter

Bird flu has been detected in 17 wild birds in Dorset, the Department of Environment, Food and Rural Affairs has confirmed today, with more expected over the coming days.

This is the first confirmed finding of the virus in the UK this winter and tests have shown it is closely related to the H5N6 strain that has been circulating in wild birds across Europe in recent months. This is different to the strains which affected people in China last year and Public Health England have advised the risk to public health is very low. The Food Standards Agency have said that bird flu does not pose a food safety risk for UK consumers.

UK Chief Veterinary Officer, Nigel Gibbens, said:
This is the first time avian flu has been identified in the UK this winter and while the disease does not represent a threat to the public, it is highly infectious and deadly to birds.

As the virus has been circulating across Europe, this finding has not come as a surprise. But it is vital that anyone who keeps birds - whether a few in a back garden or thousands on a farm - is vigilant for any signs of disease, reports suspect disease to APHA and maintains good biosecurity to reduce the risk of their birds becoming infected.​
While there is no legislative requirement to put restrictions in place when this strain of virus is found in wild birds, the Chief Veterinary Officer has confirmed local measures will be introduced to help manage the potential threat.

A local ?avian influenza prevention zone? will be introduced in the area of Dorset where the diseased birds were found. This means it will be mandatory for all captive bird keepers to put enhanced biosecurity measures in place such as feeding and watering birds indoors to minimise mixing with wild birds, minimising movement in and out of bird enclosures, cleaning and disinfecting footwear and keeping areas where birds live clean and tidy. This will be in place until further notice and will be kept under regular review as part of our work to monitor the threat of bird flu.

There are no plans to carry out any culls or put movement restrictions in place.

The risk to domestic poultry nationally remains low, however good biosecurity is essential and bird keepers across the country are reminded to follow our biosecurity advice which includes specific advice for keepers of backyard flocks.

Poultry keepers and members of the public should report dead wild birds to the Defra helpline on 03459 33 55 77 and keepers should report suspicion of disease to APHA on 03000 200 301.
Trade should not be affected following the findings in wild birds, according to the rules of the World Animal Health Organisation (OIE).
