Avian influenza virus has been confirmed at a sixth Victorian farm.

Tests have confirmed the high pathogenicity H7N3 strain at a commercial duck farm which is located within the current Restricted Area in the Golden Plains Shire.

This detection is why our risk-based Restricted and Control Areas are in place and shows that our comprehensive and ongoing surveillance activities are working.

Cooked eggs and poultry meat products are safe to consume.

All bird owners are urged to report any unexplained bird deaths to the VicEmergency Hotline on 1800 226 226.

Avian influenza (bird flu)
...
​Current situation

Last updated 5pm 13 June 2024

We are responding to the detection of avian influenza at 6 Victorian poultry farms.

Five infected properties near Meredith are confirmed to have the high pathogenicity H7N3 strain of avian influenza, and the infected property near Terang is confirmed to have the high pathogenicity H7N9 strain.

Five of the infected properties are located in the Restricted and Control Areas in Meredith and Lethbridge, in the Golden Plains Shire and one is in the Corangamite Shire where movement restrictions were already in place.

All properties have been placed in quarantine and all poultry will be safely disposed of. The sites will be cleaned and cleared of the infection.

The latest detection on a commercial duck farm is not unexpected. It shows that Agriculture Victoria’s reasonable and risk-based Restricted and Control Areas and comprehensive and ongoing surveillance activities are working as they should to pick up spread of the disease.

Food safety

Consumers should not be concerned about eggs and duck meat products. , They do not pose a risk and are safe to consume.

Victoria has a secure supply chain including the importation of eggs from interstate so the current outbreak has not significantly affected supplies.

Housing requirement

We have issued movement controls that include a housing requirement for all birds within the Restricted Areas and Control Areas in Meredith, Lethbridge and Terang.

Under the housing requirement all poultry farmers, backyard flock and bird owners must house or keep their birds enclosed in cages or sheds as much as practical.

Agriculture Victoria staff are on the ground supporting the businesses and working closely with industry to contain and eradicate the virus. Contact tracing is also underway to determine the source and spread of the infection.

Avian influenza is a viral disease of birds found globally. Virus strains are described as low pathogenicity (LPAI) or high pathogenicity (HPAI).

Poultry farmers, backyard flock and bird owners are urged to report any cases of unexplained bird deaths to the VicEmergency Hotline on 1800 226 226.

While cases among humans in direct contact with animals infected with highly pathogenic avian influenza viruses are possible, the current risk to the public remains low. Find out more about avian influenza in humans from the BetterHealth Channel.

Compensation in an Emergency Animal Disease outbreak

In the event of a declared Emergency Animal Disease (EAD) outbreak, financial compensation will be available to livestock owners and business that experience livestock or property losses as a direct result of the disease.

Personal wellbeing

Stressful events can cause feelings of worry and unease, especially where there are levels of uncertainty involved, but there are things you can do to take care of yourself.

CANBERRA - Highly pathogenic avian influenza has spread to a seventh poultry farm near Melbourne, the government of Australia's Victoria state said on Monday.

Six of the properties have an H7N3 flu strain and a seventh has an H7N9 strain, it said. Neither is the H5N1 type of avian flu that has infected billions of wild and farmed animals globally and raised fears of human transmission.

"Restricted and control areas are in place surrounding all infected premises," Victoria's agriculture department said in a statement.

Australia: 7th Victorian Farm Struck With H7 Avian Influenza

Victoria : Credit Wikipedia

#18,130

While Australia has been spared dealing with HPAI H5N1, they are wrestling with 7 outbreaks of avian H7 (1 H7N9 & 6 H7N3) outbreaks on poultry farms in Victoria. Media reports suggest in excess of 1 million chickens and ducks have been lost to the virus and culling, although no human infections have been reported.

Like everywhere else in the world, LPAI viruses circulate in Australian birds. Most are considered innocuous to poultry and humans, but when an H5 or H7 LPAI virus spreads among poultry it can sometimes spontaneously mutate into an HPAI strain.



While often these HPAI outbreaks are limited to a single farm, the virus can be inadvertently spread by moving birds, eggs, feed, equipment or personnel between farms. Less commonly, it may be picked up and carried to other farms by local or migratory birds.

First today's update from Agriculture Victoria on what has quickly become Australia's largest avian flu outbreak, after which I'll have a bit more on the history of H7 viruses.

Current situation

Last updated 9 am 17 June 2024

Agriculture Victoria is responding to the detection of avian influenza at 7 Victorian poultry farms. Avian influenza is a viral disease of birds found globally. Virus strains are described as low pathogenicity (LPAI) or high pathogenicity (HPAI).

Six infected properties near Meredith are confirmed to have a high pathogenicity H7N3 strain of avian influenza, and one infected property near Terang is confirmed to have a high pathogenicity H7N9 strain. A comprehensive surveillance program has been in place in the restricted and control areas in order to detect the presence of such viruses.

Restricted and control areas are in place surrounding all infected premises, within both the Golden Plains and Corangamite shires.

All properties have been placed in quarantine and all poultry will be safely and humanely disposed of. The sites will be cleaned and cleared of the infection.

Agriculture Victoria staff are on the ground supporting the affected properties and working closely with poultry owners and industry to contain and eradicate the virus. Tracing is also underway to determine the source and spread of the infection.

Housing requirement

Agriculture Victoria has issued movement controls that include a housing requirement for all birds within the restricted and control areas in Meredith/Lethbridge and Terang.

Under the housing requirement all poultry farmers, backyard flock and bird owners must house or keep their birds enclosed in cages or sheds.

Poultry farmers, backyard flock and bird owners are urged to report any cases of unexplained bird deaths to the VicEmergency Hotline on 1800 226 226.

Food safety

Consumers should not be concerned about eggs and duck meat products. They do not pose a risk and are safe to consume.

Victoria has a secure supply chain, including the importation of eggs from interstate, so the current outbreak has not significantly affected supplies.

Human health

While cases among humans in direct contact with animals infected with highly pathogenic avian influenza viruses are possible, the current risk to the public remains extremely low. Find out more about avian influenza in humans from the BetterHealth Channel.

Compensation in an Emergency Animal Disease outbreak

In the event of a declared Emergency Animal Disease (EAD) outbreak, financial compensation will be available to livestock owners and business that experience livestock or property losses as a direct result of the disease.

Personal wellbeing

Stressful events can cause feelings of worry and unease, especially where there are levels of uncertainty involved, but there are things you can do to take care of yourself.​

H7 outbreaks (both LPAI & HPAI) are generally regarded as less serious than HPAI H5 - although the 5 year reign of H7N9 in China (2013-2018) showed us what an H7 virus was capable of; infecting more than 1,500 people and killing roughly 40% of them. [TABLE="cellpadding: 0, cellspacing: 0"]

[/TABLE]

China's H7N9 was admittedly an outlier, as most human infections with H7 produce only mild illness. A few examples include:

• In 2018 a woman in Jiangsu Province, China was seriously infected by an H7N4 virus (see WHO Update & Risk Assessment On Avian H7N4), spending 21 days in the hospital
• NYC's 016 dramatic H7N2 outbreak in cats, and spillover into animal shelter workers (see J Infect Dis: Serological Evidence Of H7N2 Infection Among Animal Shelter Workers, NYC 2016)
• 3 mild cases of LPAI H7N7 in Italy in 2013 (see ECDC Update & Assessment: Human Infection By Avian H7N7 In Italy).
• In 2006 1 person in the UK was confirmed to have contracted H7N3, and the following year, 4 people tested positive for H7N2 – both following local outbreaks in poultry.
• The Fraser Valley H7N3 outbreak of 2004 resulted in at least two human infections, as reported in this EID Journal report: Human Illness from Avian Influenza H7N3, British Columbia.
• And in 2003 a large outbreak of H7N7 (89 confirmed, 1 fatality) in the Netherlands – with nearly all reported cases having very mild (often just conjunctivitis) symptoms.

While H7 viruses remain primarily a concern for poultry producers, their track record in humans is not entirely benign, and we need to control them before they can evolve into a bigger problem.

….
In short: More than one million birds will be killed in Victoria to stop the spread of bird flu, as poultry farmers continue to fight Australia's largest outbreak of the disease

• The current outbreak has affected seven poultry farms that house egg-laying chickens and ducks for meat production.
• What's next? Investigations are continuing into the source of the outbreak, with the disease currently believed to have spread from wild birds to domestic poultry.

Australia's largest outbreak of bird flu has hit a grim milestone, with Victorian authorities confirming more than one million birds will be killed to try and prevent the spread of the virus.

Seven farms across south-west Victoria have now been found with highly pathogenic strains of avian influenza, affecting hundreds of thousands of farmed birds.

The outbreak began on an egg farm near Meredith in May, and has continued….

Bird flu detected on New South Wales poultry farm as Victoria continues to battle its own outbreak

• short: The bird flu strain detected in the Greater Sydney Basin is different to the strain detected in Victoria in recent weeks.
• It is understood the NSW detection has come from wild birds.
• What's next? Eggs Australia hopes the early detection and quarantine will help prevent further spread.

A New South Wales poultry farm is under quarantine following a detection of bird flu.

The New South Wales Department of Primary Industries has confirmed an outbreak of HPAI H7N8 strain of avian influenza in the Greater Sydney Basin.

The virus was detected on the egg farm in the Hawkesbury district and was confirmed by testing by the Australian Centre for Disease Preparedness on Wednesday.

The HPAI H7N8 strain is not the same as the H5N1 strain that is causing concern globally.

It is also not connected to the Victorian outbreak of the of the H7N3 and H7N9 strains.
Separate event

Australian Eggs managing director Rowan McMonnies said birds on the farm would be euthanased.

"I don't have the precise number, but I do know that it was a fairly large farm. I think there were more than 100,000 birds involved," he said.

"So it's very significant blow obviously to the farm involved, but then also on the industry at large."

In a statement, NSW Agriculture Minster Tara Moriarty said the the detection was understood be a "separate spill-over event", potentially from wild birds…..:tiphat:

Experts struggle to crack mystery new bird-flu outbreak

Cassandra Morgan, Alex Mitchell and Samantha Lock
June 19, 2024

Australia’s bird-flu outbreak has worsened, stumping experts after another strain of the disease was detected on a NSW egg farm following its discovery on multiple properties in Victoria.

Avian influenza has been picked up in the Hawkesbury district, north of Sydney, although the strain was different to the one detected in the southern state, the NSW government confirmed on Wednesday.

More than one million chickens and ducks will die in Victoria in an effort to minimise the destruction caused by multiple outbreaks.

Highly pathogenic strain H7N3 was found at a seventh Victorian farm – already in quarantine – in the Golden Plains Shire in the state’s central west, Agriculture Victoria revealed during the week.
The H7N8 strain found in NSW was believed to be a “spill-over” event, possibly from wild birds.

Michael Ward, Veterinary Public Health and Food Safety chair at the University of Sydney, said he was not shocked by another outbreak but was surprised at its location.

“It’s a bit of a mystery,” he told AAP.

“But we’re pretty sure it’s linked to wild birds.”

Professor Ward said “spill-overs” could occur when wild birds….

Australia: NSW Reporting An H7N8 Avian Flu Outbreak (Different Subtype From Victoria)

#18,134

It's turning into a tough avian flu season in southeastern Australia, with New South Wales now reporting an outbreak of H7N8 after neighboring Victoria - over the past month - having announced 7 outbreaks (1-H7N9 & 6-H7N3) in poultry.

With 3 different subtypes, these outbreaks appear to be due to at least 3 different spillovers of LPAI H7 viruses from wild birds into poultry, making the NSW outbreak unrelated to the Victorian cases.​

Details remain scant, with the following notice posted a few hours ago on the NSW DPI website.



The Minister of Agriculture for NSW released the following statement:

NSW Government’s Biosecurity plan launched after Avian Influenza detected

Minister for Agriculture and Western NSW - Media Release

19 Jun 2024

The NSW Government has enacted its emergency biosecurity incident plan to address the detection of avian influenza in the Hawkesbury district on a poultry egg farm, that has been confirmed as the High Pathogenicity Avian Influenza (HPAI).

This analysis was confirmed by the CSIRO national testing labs, the Australian Centre for Disease Preparedness today.

The HPAI detected is the H7N8 type and is not the same strain as the current Victorian outbreak. It is understood at this point to be a separate spill-over event, potentially from wild birds.

High pathogenic diseases spread quickly and have a high mortality rate amongst poultry birds, which is why there has been an immediate lock down of the farm.

The detection has triggered the NSW Government’s Emergency Animal Disease response, including an individual biosecurity direction to the farm and business, closing it off.

Under the individual direction the affected egg farm has implemented quarantine to prevent the movement of equipment, and animals, to stop further spread.

A formal control order will be declared this afternoon that will extend biosecurity control to a radius of 1-2 kilometres around the farm site.

The legal instrument will guide the urgent actions of depopulating poultry and decontaminating the farm.

The Government’s Biosecurity Incident Management Team is now up and running and has been liaising with the Consultative Committee on Emergency Animal diseases to discuss immediate response plans and the National Emergency Animal Disease Management Group.

NSW consumers should not be concerned about eggs and poultry products from the supermarkets.

This detection does not pose a risk to consumer health and the products are safe to consume, if they are handled and cooked as per standard food handling practices​.

The Government will work closely with industry to reduce the risk of spread and minimise any impact on egg supply.

As outlined in yesterday’s Budget, the NSW Government takes biosecurity threats seriously with $946 million invested for protecting our State and our primary industries.

Detections like this demonstrate our Biosecurity system and plan is working to detect incursions when they occur, and then taking swift action to contain, manage, eradicate, and decontaminate.

Information on aviation influenza is available at the Department’s website here. This website will be updated as information comes to hand.​

This is the first outbreak reported by NSW since 2013, when two farms were hit with H7N2 near Young. The only other outbreak in NSW was reported a year earlier, when H7N7 struck a single farm near Maitland.

Like everywhere else in the world, LPAI viruses are common in Australian birds. Most are considered innocuous to poultry and humans, but when an H5 or H7 LPAI virus spreads among poultry, it can sometimes spontaneously mutate into an HPAI strain.





While most of these HPAI outbreaks will be limited to a single farm, the virus can be inadvertently spread by moving birds, eggs, feed, equipment or personnel between farms - and less commonly - by local or migratory birds which may pick it up and carry it some distance.

Hence the OIE/WOAH requirements to report, and quickly eradicate, all H5 and H7 outbreaks in poultry.​

H7 viruses remain primarily a concern for poultry producers, with human infections up until 2013 being both rare and generally mild. But the H7N9 virus which emerged in China in 2013 showed us that - with the right set of mutations - an H7 virus can become a formidable public health threat.

H7N9 Epidemic Waves - June 14th 2017 - Credit FAO

Luckily, that deadly strain has gone to ground since China's introductions of an H5+H7 vaccine in 2017 - and while versions of it still circulate in birds - it appears to have lost much of its affinity for mammals (see EID Journal: Evolution and Antigenic Drift of Influenza A (H7N9) Viruses, China, 2017–2019).

For now, the H7 viruses circulating in Australia show no signs of posing any kind of serious public health threat.​

But, as with all influenza viruses with zoonotic potential, things can change over time. Which is why these outbreaks must be quickly contained, before something worse can happen.

Avian influenza

ALERT

Avian influenza was detected at two commercial poultry farms in the Greater Sydney Basin in June 2024.

NSW DPI has implemented an emergency order to help manage the current cases of avian influenza.

The impacted properties are under quarantine, and NSW DPI is working closely with the impacted property using well-established national response arrangements to manage the outbreak.

Importantly the HPAI H7N8 strain detected in NSW is not the same as the H5N1 strain that is causing concern globally and is not connected to the Victorian outbreak.

If you see unusual signs of disease or suspect an exotic disease in your poultry, immediately call your veterinarian, an LLS District Vet or the Emergency Animal Disease (EAD) Hotline 1800 675 888.
