Avian Influenza Prevention Zone
An Avian Influenza Prevention Zone (AIPZ) mandating enhanced biosecurity is in force across the UK. In addition, mandatory housing for kept birds is in force across the unitary authorities of the East Riding of Yorkshire, the unitary authority of York, the City of Kingston upon Hull and all districts in Cheshire, Herefordshire, Merseyside, Lancashire, Lincolnshire, Norfolk, North Yorkshire, Shropshire Suffolk and Worcestershire to mitigate the risk of further outbreaks of disease occurring.
All bird keepers in the AIPZ with mandatory housing must keep their birds housed to protect them from bird flu. This applies to pet birds, commercial flocks and just a few birds in a backyard flock. These housing and biosecurity measures are to mitigate the risk of further outbreaks of disease occurring.
The Code of Practice for Racing Pigeons states: “When housing measures are in force as part of an AIPZ, birds will only be allowed out for exercise for up to one hour once each day. If the loft is not within a protection or surveillance zone, you may train birds as a single loft but must not mix birds from other lofts unless you have met the requirements of the general licence (this would constitute a gathering and must be notified to the APHA 7 days in advance and comply will all the requirements of the relevant bird gatherings General Licence). You must not have an open loft that allows the birds to freely come and go, which would increase the chance of wild birds entering your loft and contaminating it.”
The updated General Licence for Bird Gatherings may be seen here.
Interactive Map
Keepers can check if they are in a bird flu disease control zone using the Animal and Plant Health Agency’s (APHA) interactive map. Further information on the measures that apply in the zones can be found in Defra’s Bird flu: rules in disease control zones in England guidance and the zone declaration available via the notifiable disease case finder. Disease control zones will remain in place until all disease control and surveillance activities in the zones have been successfully completed and there are no suspect cases are under investigation in the zones.
Keepers must keep a close watch on their birds and kept mammals (including pets) for any signs of disease, and seek prompt advice from a vet if they have any concerns. You can find further information on how to spot and report bird flu in poultry and other captive birds and how to keep other pets, such as cats and dogs, safe from bird flu.
Clinical signs indicative of infection with an avian influenza virus must be reported in England to Defra Rural Services Helpline on 03000 200 301. In Wales, contact 0300 303 8268. In Scotland, contact to the local Field Services Office. Failure to do so is an offence.
All bird keepers must register their poultry and other captive birds (with the exception of certain psittacines and passerines), even if only kept as pets. Registered keepers will receive regular updates and guidance to help protect their birds from avian influenza. In addition, anyone can subscribe to APHA’s free animal disease alerts service for the latest information on updated risk levels, guidance and new cases in Great Britain regardless of whether they keep birds.
In Great Britain members of the public are encouraged to report findings of dead wild birds using the online reporting system or by calling the Defra helpline (03459 33 55 77). By reporting dead wild birds, you are helping Defra and APHA understand, the risk to different species groups of wild birds, the risk posed to poultry & other captive birds and the risk of overspill into mammals.
The UK Health Security Agency (UKHSA) has said that avian influenza is primarily a disease of birds and the risk to the general public’s health is very low. Do not touch any dead or sick wild birds you find. The Food Standards Agency advises that avian influenzas pose a very low food safety risk for UK consumers. Properly cooked poultry and poultry products, including eggs, are safe to eat.
