During the AI Symposium on managing outbreaks in Taiwan, the main subject was managing the outbreaks without breaching animal welfare during the culling operations. Although it seams impossible, this can be done using the Anoxia method (see also www.N2GF.com for more information), under the condition that the entire process is been taking into account: killing of animals, carcass disposal, transport & logistic, Occupational Health & Safety, environmental issues, pest control, contact between animals and humans: all these factors contribute to the risks of spreading. If one factor fails, the virus can escape and infect the next flock, making it needed to kill more birds. For that reason, all factors are equally important to maintain animal welfare during outbreak situations.
In a number of recently published studies, Professor Stegeman (University of Utrecht, Holland) explains that serologic spreading of viruses is related to human contacts with contaminated infected animals, carcasses, manure and materials infected/suspected animals; movements of farm labourers, products, equipment etc. Most of these contacts (and movements) take place prior, during, and after the culling procedure, whereas the quantity and the intensity of the contacts – thus this human contact/materials are decisive factors for the serologic spreading of viruses to enter farms and most likely play an important role in spreading between farms. Suspicion/infection of farm animals inevitably leads to preventive culling of all farm animals within the direct proximity. For that reason, the serologic spread of viruses has become a major animal welfare indicator that has to be taken into consideration as such.
Each culling procedure features its own unique contact pattern between animals and humans and is based on applied culling, disposal and transport technique. These contact patterns related to the specific combination of applied methods, defines the major contribution factors for spreading of infections. Therefore should the potential risks of these procedures be evaluated and rated on the art and the intensity of the potential contact between animals and humans/materials, prior, during and after the procedure.
Therefore, the entire procedure of killing, disposal and transportation is therefore considered as Major Interest, in terms of animal welfare.
This is the 3th presentation of a series of documents, presented during the conference on the application of the Anoxia method for euthanizing animals.
The conference is held in Canberra (Australia) on February 21, 2014. The conference is organized for representatives of animal welfare organizations, Australian animal health authorities and the industry and gives an overview of more scientific based information on the Anoxia method.
This is the second presentation of a series of documents, presented during the conference on the application of the Anoxia method for euthanizing animals.
The conference is held in Canberra (Australia) on February 21, 2014. The conference is organized for representatives of animal welfare organizations, Australian animal health authorities and the industry gives a general overview of the Anoxia technique.
This is the 1st presentation of a series of documents, presented during the conference on the application of the Anoxia method for euthanizing animals. The conference is held in Canberra (Australia) on February 21, 2014. The conference is organized for representatives of animal welfare organizations, Australian animal health authorities and the industry and gives an overview of some important practical issues related to Emergency Response, based on my experiences during the outbreak of H7N7 in Holland.
In January 2012, the OIE gave in Japan an update on the latest developments in killing animals for disease control purposes. The Anoxia method was one of the presented techniques. Today, one year later, the Anoxia technique is commercially available worldwide. Inhumane killing of animals is not longer necessary and the risks of getting infected has been reduced to a minimum.
The most animal welfare friendly euthanasia technique for killing poultry is now commercially available within the EU. According to Regulation EU 1099/2009 each poultry farm within the EU need to be equipped with a slaughter technique (listed in this new regulation). Manual techniques like neck pulling are banned from being used. This means that each poultry farm in Europe needs to be equipped with euthanasia equipment that this technique is easy to use.
The method we developed is based on the principle of Anoxia: total absence of oxygen, using only water, soap, and nitrogen. The animals are stunned within 30 seconds. 25 seconds later, the animals die without any unnecessary stress or pain.
The Anoxia method is developed by Anoxia Europe BV (Hoge Eng 52a, 3881 TN Putten, Holland. For more info, please contact dr. Michiel van Mil, +31 341-701687, Mobile +31 652 266944, email firstname.lastname@example.org. www.anoxia-europe.com.
I would like to share my vision the possibilities to prevent the return of H7N9. All measures taken in the past to stop major outbreaks have totally failed in every sense of the word. It is time for radical change in dealing with outbreaks. This is my step-by-step approach to battle outbreaks.
This month, a long awaited report has been published in Poultry science in the edition of May 2013. The team concluded that the trials conductedduring this study provide proof-of-principle thatsubmersion in gas-filled, high expansion foam is a rapid and highly effective method of euthanasia, which may have potential to provide humane emergency killing or routine depopulation action of high expansion, gas-filled foam is anoxia.
On-Farm Killing Of Poultry Using Gas – UK Experiences from January 2007. David Pritchard (Senior Veterinary Consultant Animal Welfare) and Gordon Hickman (Head of Contingency Planning), both in their role of advising DEFRA on animal welfare issues, describing mass depopulation methods, comaring these methods with the Anoxia method of using Nitrogen base gas foam. Today, their presentation is still very relevant, since it was the start of what has become the Anoxia method.
Interesting read, including nice graphics!
Once the source of the H7N9 infection is found, how should the Chinese authorities you organize the response? Regarding that it is more than likely that animal-to-human contact could cause a human pandemic, all existing response methods are doomed to fail.
One of the remaining options is the novel Anoxia method, based on the absence of oxygen under atmospheric conditions. When the Chinese authorities able to apply this technique throughout all provinces, using well-equipped and trained firefighters, they could be able to stop the pandemic before it starts. The Anoxia method is therefore the weapon of choice.
