High standards of biosecurity must be maintained as good practice for the health of your birds, and that good biosecurity is an essential defence against diseases such as avian influenza and is key to limiting the spread of avian influenza in an outbreak. Keepers must keep a close watch on their birds for any signs of disease, and seek prompt advice from a vet if they have any concerns. Clinical signs indicative of avian influenza 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.
