Dear President,
For the fifth time this week I am forced to inform yourself with outbreaks of bird flu (Avian Influenza, AI) in the Netherlands. Meanwhile 6 companies directly affected as a result of (preventive) culling. for the farmers, their animals and their communities, this outbreak downright awful. Families and families often decades to their company have built in one fell swoop lose all their animals, with all emotions then. Communities living along with neighbors, friends and acquaintances.
The consequences of the current outbreak of bird flu are very serious. I have Therefore, early last week brought a radical package of measures to further spreading of the avian flu to counteract. The entire poultry This affects, I am very aware of that. I think it is necessary, in the interests of entrepreneurs and their animals, all the set in their power to prevent a larger outbreak.
Further to my letters of 16, 18, 20 and 21 November. I tell you about the status of the outbreak and the measures.

Bird flu Kamperveen
Research has determined that the bird flu on the broiler parent company Kamperveen the highly pathogenic H5N8 type
is concerned. This variant was also found on the company and the Hekendorp company in Ter Aar. In the area with a radius of 1 km around the infected holding in Kamperveen are two poultry farms. As a precaution, the two companies decided preventive culling. Depopulation is completed today. At one of the companies are clinical signs in ducks found matching bird flu. It is now established that it is also at this ducks company to a H5 strain of bird flu is. It is not yet clear whether it is a low pathogenic or is a highly pathogenic variant.
Between 1 km and 10 km area are also 32 other poultry farms. These companies are sampled and tested for bird flu. Tomorrow are expected to be at the end of the day, the results known.

Preventive culling Barneveld
Barneveld is a company today with about 8,000 ducks precaution culled. Research has shown that this company is visited by a truck that was previously on the infected ducks company Kamperveen been. Given the location of the ducks in the poultry business rich area of Barneveld I want to take any risk regarding possible spread of the bird flu virus.
There are currently no suspected cases of bird flu in Barneveld.

As indicated in my letter yesterday in the radius of 10 km from the affected farm found in Ter Aar any company with bird flu. the depopulation of the affected company, as well as the previously affected company Hekendorp, has been completed. The highly pathogenic strain of avian influenza is very contagious among poultry. For chicken, this version is deadly. Bird flu is a zoonotic disease, meaning that infection from animals to humans can be transferred. This only happens when there is direct and close contact with infected poultry. People who are ill be of bird flu have the same symptoms as in an ordinary winter flu, generally expires mild bird flu in humans.

The on Thursday 20 November. Promulgated measures endure. I refer you refer to my letter of 20 November. on Avian Ter Aar. The website contains the most http://www.rijksoverheid.nl/onderwerpen/vogelgriep questions and answers, as well as a link to the relevant regulations. In addition, business owners with questions can contact via RVO.nl
call center (088 042 42 42) today and tomorrow from 08.30 to 22.00h can be reached.
Cause bird flu research
Today I had contact with my German colleague, the Minister of Agriculture. In the vicinity of the turkey business in Mecklenburg-Vorpommern (Germany), where also the highly pathogenic H5N8 type has been found, is a torque of 6 mallards examined AI. Of the six ducks, there are three negative found, was detected in two ducks low pathogenic avian influenza and 1 duck tested positive for the highly pathogenic H5N8 type. Netherlands and Germany are working closely together for the cause of bird flu trace. Together with Germany, I will ask the European Commission to support of this research, including financially.
animal Welfare Commission
In a larger outbreak of an infectious disease, which measures be taken in the field of housing and / or culling, a
committee set up to monitor the implementation of measures are taken in the context of animal welfare. This committee will determine whether this is done in a responsible manner. The committee was established, headed
the chairman of the Council for Animal Affairs.
In relation to animal welfare, I have decided that the staff of animal ambulances is allowed to sick birds, if they are located in a life-threatening situation, transporting it to a vet. this exception in the regulation only applies to transport wild birds and birds of hobby farmers outside the protection and surveillance zones of 3 and 10 km around the infected farms.
In connection with the expiration on November 23 axis of the period of up to 72 hour standstill tomorrow I will inform you in detail.
(W. G.) Sharon A.M. Dijksma
State Secretary for Economic Affairs

Bird flu H5N8 variant appears in Kamperveen
Photo: ANP Previous Image 1 of 2 Next Image
The bird flu earlier this week showed up at a poultry farm in the Dutch Kamperveen, in the province of Overijssel, is indeed the highly contagious H5N8 variant. That the Dutch State Secretary Sharon Dijksma of Economic Affairs announced Saturday. That variant popped up earlier in Ter Aar (South Holland) and Hekendorp (Utrecht). In the Dutch town of Barneveld eight thousand ducks were culled.
The affected company Kamperveen bred parents of future broiler. All 10,000 animals are slaughtered. In an adjacent duck breeding bird flu has also surfaced. Ducks have 'clinical signs consistent with "the disease. Even animals that are culled. It goes to the ducks in each case to H5 bird flu, which has been established, but it is not yet clear whether it also concerns the variant N8.

In the area are 32 other poultry farms investigated. The outcomes are likely to be known Sunday. A truck after a visit to the duck farm in Kamperveen drove to a company in Barneveld. There are Saturday 8,000 ducks slaughtered. There is no suspicion of bird flu, but Dijksma want to take any risks because Barneveld is in the heart of the poultry industry.

Six companies culled

Six companies have been culled. Dijksma calls it terrible for farmers. "Families and families often decades have built their business, in one fell swoop all their animals lost, with all the accompanying emotions. Communities living along with neighbors and friends. "

The animals had to be killed because the ducks company is visited by a truck that was previously a duck business in Kamperveen where bird flu has broken out, has visited. Barneveld is located on the Veluwe, which is the heart of the Dutch poultry industry. The Dutch State Secretary Sharon Dijksma therefore wants to take any risk of spreading the virus.

Fears of massive empidemie

Poultry farmers in the Netherlands are afraid of a new mass epidemic as in 2003, when a third of the total poultry had to be culled. "If the bird flu from spreading to the Veluwe is the incalculable damage," said Gert-Jan Oplaat, chairman of the Dutch Union of Poultry Farmers (NVP).

In Belgium there is as yet no bird flu. As a precaution since Friday have set an indoor confinement for professional poultry farmers in our country.

Tests confirm high-path H5N2 in British Columbia poultry
Filed Under: Avian Influenza (Bird Flu)
Jim Wappes | Editorial Director | CIDRAP News | Dec 04, 2014

Canadian health officials today confirmed highly pathogenic H5N2 avian flu in two of the four H5-related poultry outbreaks in British Columbia's Fraser Valley near Vancouver, one of several evolving stories on avian flu outbreaks around the world.

Harpreet Kochhar, DVM, PhD, Canada's chief veterinary officer, said in a press briefing today that test results on turkeys at a farm in Abbotsford and on chickens at a farm in Chilliwack confirmed highly pathogenic H5N2. Two other farms, also in Abbotsford and Chilliwack, that received chickens from the first Chilliwack farm have birds that tested positive for H5; they await confirmatory testing on the exact strain.

"The Canadian Food Inspection Agency's [CFIA's] testing at the National Centre for Foreign Animal Diseases has confirmed the strain causing the avian influenza outbreak on two farms in the Fraser Valley as a highly pathogenic H5N2 virus," Kochhar said.

Authorities in the Netherlands, meanwhile, have reported a fifth outbreak of H5N8 in domestic birds, while India is combatting a third outbreak of H5N1 in poultry.

Confirmatory tests awaited for 2 farms
"The Province of British Columbia has informed the CFIA that preliminary test results from the two additional farms that were quarantined yesterday are presumptive positive for H5 avian influenza," Kochhar noted. "The CFIA will conduct further confirmatory testing."

The CFIA yesterday placed the third and fourth farms under quarantine and said the agency in the coming days will cull and dispose of all birds on the affected farms. A news release yesterday from the CFIA said it will compensate farmers for lost poultry, paying $20 for a non-breeding chicken, $1,200 for a breeding chicken, $70 for a turkey, and $1,050 for a breeding turkey.

The agency said other compensation might also be available. All farms are within about 5 miles of each other.

Jane Pritchard, DVM, chief veterinary officer with British Columbia's Ministry of Agriculture, said at the press conference that the H5 findings in the additional farms were not surprising. "These results were expected based on the tracing of bird movement from one of the original farms," she said.

"It was great work on the ground that predicted the likelihood that these farms would be positive and led to the precautionary quarantine on farms 3 and 4. Through due diligence we were ahead of the game on this."

She added that officials have not detected other unusual losses of poultry on other Fraser Valley farms or symptoms of avian flu in birds. CFIA and British Columbia authorities are going from farm to farm to monitor for further outbreaks.

Pritchard said the disease is unlikely to go undetected because of its impact on birds. "We think that it's about a 3- to 5-day incubation period. And we also know that if it hits, the [poultry] producer isn't going to miss it."

In a report posted by the World Organization for Animal Health (OIE) yesterday, officials specified that the outbreak at the initially affected farm in Chilliwack was restricted to one of three barns. In the affected barn, all 700 of the 24-week-old chickens died from H5N2.

One adjacent unaffected barn contains 47-week-old chickens, while the other contains 1-week-old pullets. The farm housed 7,000 poultry before the outbreak.

Pritchard said that at the Abbotsford turkey farm, the "vast majority" of 11,000 turkeys died from H5N2. The remainder in the barn will be culled, as will flocks of about 3,000 and 14,000 in other barns, she added.

Signs of mutation
Canada has experienced low-pathogenic H5N2 outbreaks in British Columbia in 2005 and 2009 and in Manitoba in 2010, but this appears to be the first outbreak of highly pathogenic H5N2 in the country.

In response to a question, Kochhar said the change "is reflective that these viruses are actively mutating." He said the high-path designation means the virus is both highly contagious and produces high mortality in domestic birds.

When asked if the outbreak is showing signs of being contained, Kochhar said it's still in its early stages. Pritchard added, "Our intention is to come out of this quickly and get back to normal as soon as possible."

Fifth Dutch H5N8 outbreak
In the Netherlands, a second outbreak of H5N8 avian flu in Kamperveen, within a kilometer of a previously affected farm, has brought that country's H5N8 outbreak total to five, according to a report filed with the OIE yesterday.

Of 14,600 birds on the farm, 100 contracted the virus, but none fatally. To stamp out the outbreak, however, all poultry on the farm were culled.

The report also confirmed the fourth outbreak, which was reported by the media on Dec 1. It involved 28,000 layer and breeding hens on a farm in Zoeterwoude, in South Holland province, 25 of which became infected. As noted in the media, all chickens on the farm were destroyed.

In response to the recent H5N8 outbreaks in the Netherlands, Germany, and the United Kingdom, the OIE today issued a statement calling for better disease surveillance and control in animals.

"To date, the H5N8 strain has not been linked to any cases in humans," the OIE said. "Nevertheless, it is important to remain on the alert given the capacity of influenza viruses to mutate. With 75% of human emerging diseases being derived from pathogens transmitted by animals, whether domestic or wild, public health protection is inextricably linked to the preservation of animal health.

"The OIE issues a reminder that poor management of disease control at source in animals, irrespective of whether diseases are potentially transmissible to humans, can have consequences that are often severe for the local population and economy, and even at a regional and global level," the agency added.

Third H5N1 outbreak in India
India, meanwhile, has confirmed a third outbreak of H5N1 avian flu in a week, according to another OIE report.

The outbreak, in Alappuzha in Kerala state on the southwestern tip of the country, killed 2,554 ducks in a village flock of 138,063 ducks. An additional 26,746 birds were culled.

The previous outbreaks were in the same region of Kerala. One affected a flock of 228,907 ducks, and the second a flock of 13,000 ducks. All three outbreaks began on Nov 20, with different reporting dates.

Bird flu: new high security virus
Keywords: Avian Influenza , poultry , H5N8 , H5N2
By Marielle Court - on 12.08.2014 Curb icon
Derivatives H5 virus family recently hit poultry farms, the Netherlands and Canada. Scientists are very attentive to any transfer from animals to humans.
No way to panic. But before the expansion of the H5 virus family of bird flu , with two new children, H5N8 and H5N2, scientists are on alert.
"Until then limited to Asia, particularly South Korea, H5N8 has recently spread to Europe," says Thierry Pineau, Head of the Animal Health Department of INRA (National Institute for Agricultural Research). Spotted in Germany and England, he made ​​a big splash there two weeks on farms in the Netherlands , where he had to be slaughtered preventively 50,000 poultry farms and many are under surveillance.
On the other side of the globe, on Canada's Pacific coast, H5N2 has infiltrated some farms. To try to stem the spread of this highly pathogenic virus, experts decided to euthanize the weekend some 80,000 poultry in four British Columbia farms that were immediately quarantined .
No risk to humans
Unlike H5N1, which can affect men with a very high mortality rate (248 deaths of 394 cases recorded in 2005), the two newcomers concern only birds. "There is no risk of this happening to humans through infected food because the animals never make it to the slaughterhouse," said his side Jean-Luc Guérin, a researcher at within the unit "pathogen-host interactions agents" of the Institute. As for the possibility that the H5N8 is transmitted by air, it is not possible at the moment. "For the moment this virus is not adapted to multiply in humans, it is much less efficient than the H5N1," says the scientist.
However, all means are put forward to eradicate these viruses. Because of course the damage they cause in animals but also to try to prevent any risk of mutation. "It is feared most marriages that could be made between several viruses that the risks of direct contagion" still provides Thierry Pineau. "There are eight in each virus genome segments. The risk is that these segments come together when two viruses infect the same cell. "The pig is a perfect host and can serve as an intermediary can both be infected by avian viruses and human viruses.
For scientists it is particularly important to create really large databases of information on the virus. "The goal is to allow us to see, as soon as they emerge, where they come from, researchers say. It is important to identify the markers on each segment that will indicate the virulence and pathophysiological character "For nothing is simple with these agencies. The same marker that can be particularly dangerous in birds work differently in mammals and the man.
"Viral Biodiversity"
There is now in France as in other European countries bioconfinés laboratories. Scientists working in these places ultraprotégés create "viral biodiversity". This allows to anticipate and possibly "know the dangerous combination." This would be the case of a recombination of H5N1 and H1N1, "particularly formidable and would fear a pandemic comparable to that of the 1918 Spanish flu," says an article Abdenour Benmansour of the research unit virology and immunology molecular.
This resurgence of avian flu reinforces the scientists in the idea that we maintain high surveillance system. However, as soon as pandemics regress, financing related retract. "The financial resources were switched to other priorities. We must return to a level sufficient to have the means to detect new cases as soon as they emerge, "said Bernard Vallat, director of the OIE World Organisation for Animal Health. Examples of recent days show that we can never be complacent.
