A 3km Captive Bird (Monitoring) Controlled Zone (Avian Influenza), or CBMCZ zone, has actually been stated around the contaminated properties, to restrict the threat of illness spread.
Within this zone, bird motions and events are limited and all holdings that keep birds need to be stated.
Councillor Richard Church, cabinet member for a Safer Powys, said: “It is vital keepers of birds remain vigilant and ensure they have the very highest levels of biosecurity in place.
“It is also important people do not touch or pick up any sick or dead birds to avoid spreading the virus.
“Public health advice remains that the risk to human health from the virus is very low and food standards bodies advise that avian influenzas pose a very low food safety risk for UK consumers.”
If you discover dead wild waterfowl – swans, geese or ducks – or other dead wild birds, such as gulls or birds of victim, you ought to report them to the Defra helpline on 03459 33 55 77.
