HPAI UPDATE NZ

Avian Influenza incident in Australia

 

In the past week it was confirmed that two egg farms in the state of Victoria, Australia, and one in Western Australia has tested positive for a High Pathogenic Avian Influenza (HPAI) virus through preliminary testing. Subsequent testing has confirmed it is the H7N3 strain in Victoria and H9 in western Australia, not the highly virulent H5N1 strain dominating in countries around the world. H5N1 has not been detected in Australia.

New Zealand and the Pacific Islands remain the only two countries without a strain of HPAI, however our remote geographic location does not make us exempt from risk.  As such, New Zealand’s biosecurity measures are moving to a new phase of vigilance and coordination.

Our egg and poultry farmers remain the frontline force for early detection at a local level. Nationally, extensive work is underway to best prepare for a response, including business continuity and biosecurity resilience. Industry is working closely with the Ministry for Primary Industries (MPI), Biosecurity NZ, and Food Safety NZ.  Together we are part of a coordinated response called ‘One Health’. Its purpose is to prepare for an incursion of HPAI across MPI, Government, the Department of Conservation, Dairy NZ and the Ministry of Health, and to respond rapidly.

Avian influenza is mostly spread by wild birds contaminating food or water supply.  It can spread rapidly by the movement of eggs, birds, people, vehicles, farm equipment between farms, as well as aerosols, litter, biting insects and vermin. Therefore, the highest levels of biosecurity are paramount for all poultry owners.

A reminder of the symptoms to look out for follows. A poster for action should avian influenza be suspected on farm is with this update.  Further information about avian influenza and the current response is available on MPI’s website:

What are the symptoms of AI?

 

  • sudden death
  • respiratory signs (noisy or rapid breathing, coughing, sneezing, increased nasal secretions)
  • conjunctivitis
  • swelling of the head
  • purple discolouration of the comb and wattles
  • rapid decrease in feed and water intake
  • decreased egg production
  • ruffled feathers
  • depression
  • closed eyes
  • diarrhoea
  • nervous signs (twisted neck, inability to stay upright, inability to fly, uncoordinated movement, walking or swimming in circles, partial or full paralysis).

 

What to do if these symptoms occur?

If any of these symptoms appear, you must call the MPI Exotic Pest and Disease Hotline 0800 80 99 66.  Do not handle sick birds yourself.
