Bird flu measures that require flock owners to adhere to strict biosecurity rules to prevent the disease’s spread have come into effect.
Known as Avian Influenza Prevention Zone (AIPZ) measures, the rules allow poultry and captive birds to go outdoors but steps must be taken to ensure no wild birds can access their food or water.
Mandatory rules on cleaning and disinfection must also be followed.
Agriculture Minister Andrew Muir said the measures were “vital tools” in the fight against disease. He added that similar requirements have been introduced in the Republic of Ireland at the same time.
He said the onset of winter migration meant the risk of bird flu being introduced via wild birds is “heightened”, adding that the disease “can cause devastating impacts for those affected and our wider industry”.
Muir has asked all bird keepers to take the appropriate action to protect their birds, the Northern Ireland flock and wider agri-food industry.
Chief veterinary officer Brian Dooher added that “stringent, mandatory biosecurity measures” help prevent the spread of the disease from wild birds.
“There is currently no requirement for poultry to be housed, and bird gatherings are not prohibited at this stage, but this will be kept under constant review,” Mr Dooher said.
“I would encourage all flock keepers, even if you keep just one bird, to review and reinforce your biosecurity in order to prevent an incursion of the disease into our poultry flock.
“Avian influenza can have a significant and devastating impact on our poultry industry, international trade and the wider economy, it is imperative that we do not become complacent.”
About 20,000 chickens were culled during a recent confirmation of the disease at a commercial farm in County Tyrone.
