Overkill on Bird Flu orders

 Politicians and bureaucrats in Victoria have  panicked themselves into an absurd ‘Lock up your chickens’ order in a knee-jerk response to a handful of bird flu cases. They never learn. Previous outbreaks have been spread by staff working on multiple intensive production facilities rather than contact with wild birds in open paddocks. Chickens kept in overcrowded conditions are far more susceptible to infections than birds with plenty of space around them.

Disease transmission between egg farms

 

Some people wonder why diseases like avian influenza are allowed to infect so many birds on different properties. Well there is no mystery about it! Politicians have allowed highly intensive poultry facilities to be established. As a result of high production, the businesses are required to sell huge volumes of eggs through supermarkets. In order to keep their contracts, producers must guarantee supply and the only way they can do that is to purchase eggs from other producers. They stamp the eggs at their packing station and pretend they are their own brand. The eggs are then trucked off to the supermarkets and sold to unsuspecting consumers. This transfer of eggs between properties is a vector for the transmission disease from property to property and most of them also share workers.

Freerange hens not to blame for Avian Influenza

 Claims by major egg producers that the current Victorian outbreaks of Avian Influenza had been caused by hens on freerange farms are false.The outbreaks around Lethbridge and Meredith have been on large, corporate businesses which cannot be compared with genuine freerange farms. The problem in one of overcrowding. Any disease spreads like wildfire when animals are in confined spaces. Political interference, allowing intensive producers with 10,000 hens per hectare to classify themselves as free range was simply absurd. An adult hen produces half a cubic metre of manure a year. Which means that 10,000 chickens produce a mountain of 5000 cubic metres on each hectare of land each year  - resulting in health risks as well as degrading soil health and waterways. Ohio State University says: "HPAI virus infection in poultry (H5 or H7 viruses) can cause disease that affects multiple internal organs resulting in a mortality rate of up to 100%, often within 48 hours. When H5 or H7 avian influenza outbreaks occur in poultry, infected flocks are typically depopulated or culled. The preferred method of stopping spread is to quarantine and screen flocks that are near or linked to the infected flock."

Beat the egg shortage

 Shortages of eggs on supermarket shelves is almost certain to become more severe in Victoria as currently hens at five major production facilities have been hit by outbreaks of Avian nfluenza.

The growing demand for freerange eggs can be met by people setting up their own farms. More genuine free range farms are needed to give consumers a real choice. Every township in the country should have a nearby egg farm instead of requiring eggs to be trucked across the country to a stupidmarket.


Our politicians changed the Australian free range standard to allow intensive producers to sell eggs with  misleading free-range labels. Egg cartons must display stocking densities, but as there’s no actual requirement for the chickens to go outside, the labels are meaningless. Changes to the freerange definition protects big producers from prosecution under Australian Consumer Law.The ACCC had been so successful with various prosecutions in the Federal Court that corporate egg producers demanded protection.

High stocking densities are more stressful for the chicken. Hens display some aggressive behaviours such as pecking, bullying and even cannibalism as they fight it out to maintain their hierarchy in cramped conditions, making way for justifications for widespread beak-trimming and de-beaking.10,000 hens per hectare is not sustainable or responsible farming.A laying hen produces half a cubic metre of manure a year. So, a stocking density of 10,000 hens per hectare means that farmers who follow that advice see their land covered with 5000 cubic metres of manure per hectare every year. High levels of ammonia, nitrogen, potassium and phosphorus in hen manure can destroy soil health and leach into the ground, leading to contamination of waterways. labelling requirements and standards for free range egg production introduced by poiticians in 2018 destroyed any remaining consumer confidence in the Australian egg industry.

The standard allowed intensive production systems to be classified as free range and protects intensive producers from prosecution under Australian Consumer Law. We still have an eBook available to help set up your own genuine freerange egg farm. Full details are on our website

Avian flu warning from Invasive Species Council

 

Australia’s Invasive Species Council says the country is not prepared for the potential arrival of a deadly form of avian influenza.

The Council was formed in 2002 to urge stronger laws and policies to protect our natural systems from harmful pests and diseases. It recently called on the government to draft a national response plan for a possible outbreak of avian influenza in the wild. Avian influenza virus subtype H9N2 was first documented in Indonesia in 2017. It has become prevalent in chickens in many provinces of Indonesia as a result of reassortment in live bird markets. Low pathogenic avian influenza subtype H9N2 virus-infected poultry provides a new direction for the influenza virus. According to the latest research, the Indonesian H9N2 viruses may have developed through antigenic drift into a new genotype, posing a significant hazard to poultry and public health.

Poultry farmers in Quebec are grappling with a series of outbreaks of deadly avian flu, causing the deaths of nearly a million birds. The latest proof of interspecies transmission proposes that the next human pandemic variant will be the avian influenza virus subtype H9N2.

Avian influenza causes havoc

 At least 5% of egg laying hens in the United States are reported to be infected with avian influenza; The infection, which affects hens in 29 states is cutting production and will result in increased mortality.

Only a matter of time before we have avian influenza here again

 It will be only a matter of time before we have another round of Avian Influenza in Australia once residents return home from overseas and tourists are allowed in. Waves of avian influenza in China,  other Asian countries,the US, the UK and Europe have a greater risk of spreading to humans because of a high number of variants, the World Organisation for Animal Health (OIE) has said. The Director General Monique Eliot announced that “the situation is more difficult and more risky because we see more variants emerge, which make them harder to follow."

"Eventually the risk is that it mutates or that it mixes with a human flu virus that can be transmitted between humans then suddenly it takes on a new dimension, "she added.


More than 15 countries have current infections.The last avian influenza outbreak here, in 2020 disrupted the industry because of the widespread practice of moving eggs and staff between corporate egg businesses. There were nseven previous outbreaks between 1076 and 1997. As we have advised previously Factory farms have been incubating the next outbreak of Avian Influenza in this country since Ministers approved an intensive stocking density of 10,000 hens per hectare. They put the entire Australian egg industry at risk. Such high densities allow any disease outbreak to spread rapidly. One gram of droppings from a chicken infected with bird flu contains enough viruses to infect the entire flock.It also promotes the spread of other problems, such as salmonella.

Of the current 1,568 human infections with avian influenza A(H7N9), 33 have reported mutations in a gene indicating a change to high pathogenicity in poultry. These 33 cases were from Taiwan, China and  Mongolia.

Ensure pullets are properly vaccinated

When selecting pullets for a farm, it’s important to ensure they have been vaccinated against the common diseases they may encounter. Hens on genuine free range farms with small flocks sizes and low stocking densities are likely to have fewer health problems than intensive businesses running many thousands of birds, but an occasional infection may arise. When a chicken has a runny nose or conjunctivitis, you might guess that it has a respiratory illness. But which one? Avian influenza is one of the big fears - but that’s unlikely on a well managed farm. Several common chicken diseases — including coryza, infectious bronchitis and infectious laryngotracheitis — have similar symptoms, making them hard to tell apart. The treatment for each disease is different, so getting a laboratory diagnosis is essential, Coryza causes conjunctivitis, coughing and a major drop in egg production. Infectious bronchitis often affects the kidneys and reproductive system as well as the upper respiratory system. It can spread quickly, especially when hens are confined in sheds, it affects egg production but seldom kills many birds. In addition to the common respiratory symptoms, it can cause rough eggshells and uneven colouration of brown eggs. If the chickens are infected when they’re very young, the disease can destroy their oviducts.

Avian influenza kills 120 million poultry

The world-wide wave of avian flu has resulted in the loss of nearly 120 million poultry In global animal disease terms, highly pathogenic avian influenza (HPAI) is waning in its second global wave but it is estimated to have led to the loss of almost 120 million head of poultry. New outbreaks have been reported in Cambodia, Japan, Taiwan, India, Iraq, Turkey and South Africa in the last 12 months.

free range farms are not an avian flu risk

Genuine low-density free range farms do not increase the risk of outbreaks of avian influenza. A leading poultry vet has said that the two most recent outbreaks in Australia were on intensive farms with high stocking densities. In an article by Dr George Arzey in the January Poultry Digest,he said that the two outbreaks in New South Wales in 2012 and 2013 were in intensive 'free range' flocks of 50,000 hens and 160,000. “The transformation of avian influenza viruses to highly pathogenic viruses is more likely in large flocks,” he said.In earlier published work he said "It is apparent from studies that differences in the disease profile of hens in different housing systems may be encountered and that viral respiratory diseases are less likely to be encountered in small free range flocks than in intensive flocks.

Government regulations ensure the spread of avian influenza

Factory farms are incubating the next outbreak of Avian Influenza in Australia. Ministers who approved an intensive stocking density of 10,000 hens per hectare have put the entire Australian egg industry at risk. Such high densities allow any disease outbreak to spread rapidly. One gram of droppings from a chicken infected with bird flu contains enough viruses to infect the entire flock.

Effective vaccines for avian influenza in poultry not yet available

Vaccines have been developed to combat avian influenza in poultry and bird flu in humans. But scientists are reluctant to approve the mass vaccination of chickens because they believe it may not reduce the risk of infection. The vaccines appear to mask the symptoms so poultry keepers may not be aware that their birds are infected. This could allow the virus to spread widely and may cross over to humans. The vaccines developed for humans seem to be more effective in controlling the effects of bird flu.

Australia's egg industry tries a cover-up


Australia's egg industry is desperately trying to cover its tracks after major producers have been sprung conning consumers.

Bede Burke, Egg Committee Chairman of NSW Farmers claimed in an interview on ABC radio that there is confusion surrounding free-range and caged eggs, which is making future investment for the industry difficult.

He said it was a shock to see avian influenza outbreaks in the new style of free-range farms built in Australia. He said the magnitude of the outbreak was foreign to DPI staff, although the virus was eventually contained to two farms and eradicated. He acknowledged that the recent ACCC court case against Pirovic over free-range eggs was a defining case. But he tried to argue that farmers have invested in free-range production according to the existing code, which is now having a different interpretation laid over top of it. What a load of cobblers – it's purely greed. The existing code precludes intensive free range egg production but the shonky operators thought they had found a loophole! Bede Burke's attempts to defend shonky practices have not been supported by the Egg Corporation. Managing Director James Kellaway has told egg farmers " The judgement has some very important ramifications for free range egg farming, as it is now law. The judgement defines, to a degree, what free range egg farming is. As a result, I urge you all to read the judgement carefully and take any necessary steps to ensure you comply.

Aussie egg farms to pay for bird flu clean up costs


All egg farmers in Australia will be forced to pay for the costs of the avian influenza outbreak in New South Wales even though it was caused by poor on-farm practices and inadequate biosecurity procedures on the individual farms involved.

A new levy of 1.4 cents on every chick purchased by farmers will be charged, on top of existing levies. A business case has been submitted to the Department of Agriculture for an increase in the Emergency Animal Disease Response Levy.  Egg farmers have six weeks to object to the new levy so If think it's unfair on farmers who do the right thing,  object to this proposal. Send an email to AECL at contacts@aecl.org and also to the Department of Agriculture in Canberra at levies.management@agriculture.gov.au. It seems odd that a coalition Government which publicly supports small business and believes in individual responsibilty would choose a collective approach to bail out businesses which made poor decisions.

The levy increase proposal is to repay an amount of $395,000 to the Australian Government for the egg industry’s share of costs incurred for the responses associated with an outbreak of LPAI among ducks during January 2012; an outbreak of HPAI among laying hens in November 2012; and another outbreak of HPAI among laying hens in October 2013. Many farmers are asking "why should we be penalised for the greed of a couple of operators and their decisions to ignore normal business practices and biosecurity procedures."
To compare the way farmers are treated, in the European Union, 50% of costs associated with the eradication or control of Avian Influenza are covered by the Government.  I'm not suggesting that should be the case here but I don't understand why Aussie farmers who have met all biosecurity and food safety processes should be penalised to the same extent as the clowns in the industry who have been chasing quick dollars.  Where is the equity?

UN Food and Agriculture Organisation says human patients infected with avian 'flu won't infect poultry

The United Nations Food and Agriculture Organisation (FAO) says there is no evidence that human patients infected with H7N9 avian influenza can transmit the virus to animals. FAO referred to the first human case of H7N9 outside China, which was recently detected in Malaysia.
The patient, originally from Guangdong Province in China was visiting Malaysia as a tourist and has been hospitalized. Guangdong is one of the Chinese provinces most affected by the H7N9 virus.
"This case does not come as a surprise and should not be a cause for increased concern, but should remind the world to remain vigilant," said FAO Chief Veterinary Officer Juan Lubroth. "Humans that become ill with H7N9 constitute no threat to poultry," Lubroth said.
"We have no evidence that affected people could transmit the virus to other species, including birds. The highest risk of virus introduction is uncontrolled live poultry trade between affected and unaffected areas."
People become infected following close contact with infected live poultry, mostly in live bird markets or when slaughtering birds at home.
WHO risk assessments show that should infected people from affected areas travel internationally, community spread is unlikely since the virus does not have the ability to transmit easily among humans.
Lubroth observed that "Such 'imported' human cases, like the one reported in Malaysia last week, have been found in the past in previously unaffected areas of China, like Guizhou, Taiwan Province of China and Hong Kong SAR, and we will likely continue to see this in the not too distant future again. To date the virus has not been found in poultry populations outside affected areas in China."
Birds that have contracted H7N9 do not show clinical signs, which renders early detection of the virus in poultry populations more difficult.
FAO is focusing on high risk countries, facilitating risk assessment, contingency planning, expansion of diagnostic capabilities and risk-based surveillance.

Biosecurity problems led to avian influenza outbreaks

Investigations into the avian influenza outbreaks near Young in New South Wales appear to confirm that the biosecurity practices on the two farms were not up to scratch – even though they were said to be 'state of the art' facilities.

It seemed odd that the initial outbreak was able to spread so quickly to cage hens on a farm which also had birds with 'access' to the outdoors – and then to a separate cage farm.

The likely cause has now been revealed by the Department of Primary Industries in NSW.

'The highly pathogenic avian influenza (HPAI) H7N2 outbreak near Young was first detected in a free range and cage layer chicken farm near Young. The free range birds had potential exposure to waterbirds and a dam is located close to the free range poultry enterprise. Ducks have been reported on the property. Mortalities were first seen in the free range birds before clinical signs were seen in the caged birds, suggesting free range layers were infected before the cage layers. Avian influenza viruses are known to circulate in migratory and waterbirds in Australia. This incident appears to be a point source introduction by a wild bird, followed by adaptation and selection of a virus with high pathogenicity to chickens. A second infected property was detected and confirmed to be HPAI H7N2. This is a caged layer farm. Re-use of cardboard egg cartons is the most likely route of transmission from the first infected property to the second infected property and between enterprises on the first infected property.

The Emergency Animal Disease Response Agreement (EADRA) is a formal, legally binding agreement between Animal Health Australia, the Australian government, all state and territory governments, and currently fourteen livestock industry signatories (‘parties’). The EADRA covers the management and funding of responses to emergency animal disease (EAD) incidents. HPAI H7N2 is a category 2 disease, which means that government covers 80% of the costs and industry covers 20% of the costs. The industry costs are determined in relation to industries' gross value of production. Under EADRA, each industry party must take reasonable steps to ensure that its industry meets the cost sharing obligations of that industry. The Commonwealth may initially meet an industry’s cost sharing obligations, and that industry will then repay the Commonwealth within a reasonable time period.'

Statements by politicians and others about the outbreaks were factually incorrect. A comparative analysis on the number of avian influenza outbreaks in Australia between 1976 and 2013 demonstrates that most avian influenza outbreaks were in intensive housing systems. The last two outbreaks in 2012 and 2013 were in very large free range flocks. The risks of avian influenza in free range should be discussed in the context of the size of the flock and the stocking density. 
The industry needs to learn from this – for example, dams should not be located anywhere near the range area to limit the potential for wild duck access. Most of us in the free range industry have been well aware of this issue. There is also a problem with operating different production facilities on the same property. Establishing Barn, Cage and intensive Free Range sheds in close proximity to each other, with staff moving freely between the different systems, is a disaster waiting to happen.

Details needed about the Avian Influenza outbreak

We have sent a request off to DAFF, the Federal Government Department  of Agriculture, Fisheries and Forestry, asking about the outcome of the recent avian flu problems in NSW.
Egg farmers are keen to understand how the outbreak of Avian Influenza originated at Young. Has evidence been found on how it started? Were ducks involved and did the farm have a dam which could be accessed by the chickens? How was it spread throughout the original farm as we understand this was heralded as 'a state of the art' facility. Even more worrying is the question about how did it spread to a second farm - or was that a totally unrelated incident?
All eggs farmers want to ensure that our biosecurity systems are as effective as possible so it is necessary to know what went wrong in these two incidents.
We understand that all egg producers may be required to pay a levy as an Emergency Animal Disease Response to refund government costs. When is this levy likely to be imposed?

Vaccine against Bird Flu

The U.S Food & Drug Administration has approved the first vaccine for the prevention of H5N1 avian influenza. The vaccine, is for use in people 18 years of age and older who are at increased risk of exposure to the H5N1 influenza virus.
Avian influenza A viruses generally do not infect people, however H5N1 has caused serious illness and death mostly among people who have been in close contact with infected poultry. When people do become infected with H5N1, about 60 percent die, according to the World Health Organization. H5N1 has pandemic potential because it continues to infect wild birds with occasional outbreaks of influenza disease in poultry populations, and most humans have no immunity to it.

A third person has died in Indonesia this year after contracting bird flu, and 12 have died in Cambodia.

Free Range doesn't encourage avian influenza

Comments by Federal Minister for Agriculture Barnaby Joyce that more free range eggs farms will lead to an increase in the incidence of avian influenze are a result of industry hype from Corporate egg producers who want to kill off the genuine free range sector.

The industry had hoped that he would have some empathy for family farms - but he has continued down the same track as his predecessors in supporting big business.

His comments were echoed by industry vet Dr Peter Scott and by Bede Burke, chair of the NSW Farmers Association Egg Group. But just a couple of years ago, Mr Burke agreed with us that intensive 'free range' was  not in the interests of the industry - or chickens.

He is on record as saying that the Coles' drive for more free range eggs was an animal welfare disater in the making.

Mr Burke told the Tamworth City Times in December 2010 that 'profitability on free range farms was being driven down and they would become intensive open-air factories'. He said it was already happening as Coles demanded more  eggs from suppliers.

"It looks all nice and populist for the consumer, but in reality it is encouraging cowboy operations. Coles demand for free range eggs is encouraging Mickey Mouse operations run with too many birds in bad facilities."

That was Bede Burke's stated view then. Recent events have proved he was right. Wonder what happened to get him to sing a different song now?

Anyway, Here's an interview on ABC Radio Country Hour today:

Bird Flu .... Kill the ducks !!

Claims by our new Minister for Agriculture, Barnaby Joyce, supported by avian veterinarian Dr Peter Scott that the 'free range' egg production system is responsible for the outbreak of Avian Influenza on two farms near Young in New South Wales are asbsurd.

Barnaby Joyce is following in the footsteps of his ministerial predecessors in only listening to the big end of town and Peter Scott is looking after his interests as a consultant to corporate egg producers.

There is little doubt that wild ducks may be a vector in the potential spread of Avian Influenza. As Dr Scott says 1% seem to be shedding the virus. So his solution is ..... shoot the ducks !!!!

In an interview with me by Hilary Harper on ABC 774, I ackowledged that the risk of avian flu in free range birds is an issue, but the main problem is on intensive so-called free range farms in Australia. It helps to not have a dam on the farm, to reduce the possibility of water fowl coming into contact with chickens.
 
How about planning a farm which does not encourage ducks?  Dams should not be permitted on free range egg farms. Or at least there should be distance limits imposed on their proximity to sheds and grazing areas.

If wild ducks are not encouraged to visit, most of them probably won't bother. For those that do, Maremma dogs with each flock will generally chase them away as they see large birds as predators.

Holding ponds need to be installed on the massive intensive farms which the industry has set up, because the potential nutrient run-off is devasting for our waterways and neighbouring properties.

What Dr Scott knows is that each hen produces around half a cubic metre of manure a year. So at a stocking density of 10,000 hens per hectare that's 5000 cubic metres of chook poo per year on every hectare. That is totally unsustainable. But worse - the Australian Egg Corporation wanted to allow a stocking density of 20,000 hens per hectare, doubling the nutrient load to 10,000 cubic metres a year! What a crock.

The issue here is that intensive egg production facilities should not be classified as free range. Any farm which runs more than 1500 hens per hectare (and that is an absolute maximum) should not be classified as free range.

There are plenty of names they can use  - Cage Free, Barn Laid or whatever -  but Free Range should be left alone for those of us who meet consumer expectations.

Obviously it is cheaper to produce eggs on an intensive farm with 400,000 hens than on a free range farm with 2000 hens. If the cartons are properly labelled and customers understand what they are buying and choose the intensive system - that's fine.

But I think it's a total con for intensive farms to be allowed to label their eggs as free range when they are running huge numbers of hens, the hens are beak trimmed, they are using meat meal derived from poultry and additives to enhance yolk colour.

There's no question that intensive poultry farms are the problem and it is irresponsible for the Federal Minister for Agriculture to turn his back on family farms and push the barrow of the corporate egg industry. Of course he won't acknowledge that he was wrong - he will just plough on.

An investigation needs to be completed into how the outbreak started in Young and how it spread before there are any knee-jerk reactions from politicians or industry heavyweights. Research also needs to be conducted into the health issues associated with intensive animal husbandry and the adviseability of multiple production systems on an egg farm.

The call to kill the ducks as a solution to a problem generated by corporate greed makes as much sense as the badger cull in England ostensibly to reduce the incidence of bovine TB.

Senior lecturer in animal behaviour and welfare in the school of animal and veterinary sciences at Charles Sturt University, Doctor Rafael Freire thinks claims that free range egg production will encourage more bird flu outbreaks is a "bit of a stretch".

"There's a few studies on transmission to domestic populations of poultry in Europe and the evidence doesn't seem to suggest that that's a very big risk," he said. "You have to just think of it in the big scheme of things. It's transmitted to any bird that's flying around outside and of course there are millions.

"And we know very well that even birds in cages can be infected by bird flu because wild birds fly into the shed."

As a result of the Avian Influenza outbreaks we have beefed up the biosecurity segment of our workshop on starting a free range farm. It has always been an issue but the recent incidents have demonstrated that every farm needs to take the problem seriously.
