Avian influenza (bird flu)

Update – 20 October

At 11.59 pm on Monday 19 October 2020 the poultry housing order for the Restricted Area of Golden Plains Shire ended.

The Control Area boundary is now reduced (see maps below); however, the Restricted Area boundary will remain in place to ensure a staged progression toward eradication of this outbreak.

Permits are still required to move poultry, poultry products, equipment or vehicles involved in poultry production into, out of or within these Restricted Areas and Control Areas.

All poultry and captive bird owners should continue to follow good biosecurity practices in order to prevent a recurrence of the disease. Poultry owners are requested to continue monitoring their birds for signs of sickness and disease.

Avian influenza had been confirmed at four poultry farms near Lethbridge, one near Bairnsdale and one emu farm near Kerang. Cleaning and decontamination of these properties is in progress.

There have been no new infected properties detected in Victoria since late August. Decontamination and disinfection of the six infected properties is in progress. Surveillance activities continue in the Restricted and Control Areas and across the state.

There have been three different strains of avian influenza during this incident:

  • three eggs farms with highly pathogenic H7N7 avian influenza
  • two turkey farms with low pathogenic H5N2 avian influenza
  • one emu farm diagnosed with low pathogenic H7N6 avian influenza.

Restricted and Control Area Orders and movement permits

Restricted Areas and Control Areas remain in place in the Golden Plains Shire near Lethbridge, near Bairnsdale and near Kerang to stop further spread of avian influenza.

A permit is required to move poultry, poultry products, equipment or vehicles involved in poultry production into, out of or within these Restricted Areas and Control Areas.

The requirement of a permit includes for buying, selling or moving eggs, manure and chickens, whether on the side of the road, from your property, your local store, online (such as Gumtree or Facebook) or at markets. It is illegal to move these products without a permit.

Apply for a movement permit online and an Agriculture Victoria staff member will contact you.

Please see the relevant map and contact the Customer Contact Centre on (03) 4334 2715 (Monday–Friday 9 am – 5 pm, Saturday–Sunday 10 am – 3 pm) for advice on a permit.

What is avian influenza?

Avian influenza, commonly referred to as ‘bird flu’, is a highly contagious viral infection of birds. Serious forms of the disease can cause severe symptoms and sudden death in domestic poultry (up to 100 per cent of birds). Mild strains of the disease cause few or no symptoms in poultry and may go undetected in some species of birds, though can result in some deaths.

What species are affected?

Domestic poultry, ducks, geese, turkeys, guinea fowl, quail, pheasants, emus and ostriches are most susceptible to being affected by avian influenza. Many species of wild birds, including waterfowl and seabirds can carry the virus but usually show no signs of disease.

How is the avian influenza virus spread?

Infected birds shed the avian influenza virus in saliva, nasal secretions and faeces.

Wild birds are considered the natural host for the virus and usually carry it without showing any symptoms of the disease.

Sometimes the virus spills over from wild birds into domestic bird populations and may cause disease. This can occur through either direct contact between wild and domestic birds, or indirectly through the contamination by wild birds of feed or water of domestic birds.

What are the symptoms?

Symptoms associated with avian influenza can include:

  • sudden death
  • respiratory distress
  • swelling of the head
  • purple discolouration of the comb and wattles
  • coughing
  • sneezing
  • rasping breathing
  • rapid decrease in feed and water intake
  • decreased egg production
  • ruffled feathers
  • depression
  • closed eyes
  • diarrhoea
  • occasionally nervous signs.

What do I need to do?

All bird owners, particularly those living in the current Restricted and Control Areas, need to be vigilant for any signs of avian influenza in their flocks.

Avian influenza is a notifiable disease. This means that legally you must tell us if you know of or suspect the presence of avian influenza in any birds.

You can do this by calling one of the following:

  • an Animal Health Officer or District Veterinary Officer at Agriculture Victoria on (03) 4334 2715 (Monday–Friday 9 am – 5 pm, Saturday–Sunday 10 am – 3 pm)
  • the all-hours Emergency Animal Disease Watch Hotline on 1800 675 888.

Good biosecurity practices remain essential to reduce the spread of disease not just for this outbreak, but for the future. For more information please see:

Can the virus spread to humans?

The Victorian Department of Health and Human Services has advised that the detected strains of avian influenza in this incident are not a risk to the public. They rarely affect humans unless there is direct and close contact with sick birds. There are no food safety issues identified; properly cooked chicken meat and eggs are safe to eat.

If you have had contact with birds on an affected property and you are experiencing cold or flu symptoms, call your doctor or the Department of Health and Human Services on 1300 651 160 for medical advice.

Risk to Australia

Occasional outbreaks of internationally notifiable highly pathogenic avian influenza and low pathogenicity avian influenza have occurred on poultry farms in Australia.

Each outbreak was quickly detected and stamped out, with only a small number of farms affected.

Annual migration of wild birds has the ongoing potential to introduce new subtypes of avian influenza virus to Australian birds.

Australian response to avian influenza

State and Commonwealth governments and the national chicken meat and egg industries have formal arrangements in place to share the costs of responding to outbreaks of highly pathogenic avian influenza and low pathogenic avian influenza (H5/H7 virus subtypes only) . This helps to ensure that a rapid and effective emergency response can be immediately mounted if the disease occurs.

Owners may be eligible for compensation if birds or property must be destroyed to eradicate the disease.

Procedures for responding to outbreaks generally include:

  • slaughter out of infected and in-contact poultry (depopulation)
  • decontamination
  • strict quarantine
  • movement controls to prevent spread of infection
  • tracing and surveillance to locate the extent of infection.

Vaccination might be an option in some circumstances but there is no vaccine currently available in Australia.

Wild bird surveillance program

A Wild Bird Surveillance program is in place across Australia, supported by Wildlife Health Australia.

Report an unusual sign of disease or death in wild birds.
