Defra – Avian Influenza Latest Situation – 17 February 2022

Weather Warning and Avian Influenza Risk

  • Beware Storm Eunice could worsen the spread of avian influenza! We’ve been experiencing some wet and windy weather this week in the UK and there is worse to come with Storm Eunice arriving on Friday.
  • Flood water and rain water can expose poultry and other captive birds to avian influenza if it washes contamination from roofs or the surrounding environment into your birds housing or areas where their bedding etc are stored so it’s vital that you check your birds’ housing and surrounding areas.
  • Take preventative measures to protect your birds: Check bird house roofs and strengthen any weak areas, ensure drains, gutters and ditches are clear and any tarpaulins used to cover housing areas are well secured to prevent them from blowing away in the strong winds.
  • On-going maintenance is essential to maintain biosecurity: Double check birds housing and the surrounding areas for any damage, block drainage caused by the storm, cleanse and disinfect any hard standings, footwear etc using a government approved disinfectant that may have been expose to flood water
  • Wild birds may have move to different areas to avoid adverse weather protect your poultry and other captive birds make your entire premises unattractive to wild birds. Check the weather has not damaged and continue to use bird scarers, foils or streamers.
  • Turbulent weather can churn up silt underwater in ponds and reservoirs, where the virus has been shown to lie dormant for several weeks, resurfacing environmental contamination from infected wild birds  As a result, wild waterfowl could become infected and spread the virus. Keep your birds housed and away from both direct and indirect contact with wild birds.

High standards of biosecurity must be maintained as good practice for the health of your bird. 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.
