Guest guest Posted February 8, 2006 Report Share Posted February 8, 2006 Hong Kong to ban backyard poultry farming over bird flu fears http://news./s/afp/20060207/hl_afp/healthfluhongkong Hmmm... But they aren't banning cats, which can get it by eating wild birds, and they're not doing anything about wild birds, which have contact with a lot of people and poop wherever they please. Could there be a financial motivation? Looks like intensive livestock production (the people who created this virus) will be getting a huge boost in Hong Kong! If you don't want factory farms to get a nice boost in this country, write to your reps and ask them to educate the public about biosecurity and protect backyard birds. (I use congress.org). They are doing a lot of monitoring right now in Alaska, since wild birds migrate from Russia to there, and then can end up affecting our West coast migratory routes. So this issue might come up sooner than you would like. Europeans rebelled and demanded that they protect free range chickens, so they changed their rules to allow birds in covered runs that keep out wild birds. Here are the UK guidelines: http://www.defra.gov.uk/animalh/diseases/notifiable/disease/ai/poultr ykeepers.htm And here's an attractive walk-in run that meets biosecurity guidelines (keeps out wild birds). http://www.chicken-house.co.uk/walkinrun.htm And here's the latest WHO bird flu fact sheet: http://www.who.int/csr/disease/avian_influenza/avianinfluenza_factshe etJan2006/en/index.html Bird flu is in a lot of poor countries, where people might eat a sick or dead chicken because they are short on food. I see so little about that in the news. Cheryl Quote Link to comment Share on other sites More sharing options...
Guest guest Posted February 8, 2006 Report Share Posted February 8, 2006 I am an epidemiololgist who studies zoonotic diseases (transmissible from animals to humans). While I agree that intensive agriculture is bad, in the case of avian flu, the major part of the problem are these backyard farms. Avian flu has been around for thousands of years in wild birds. It is a stable virus in these wild birds. It mutates into a more virulent form when it mixes with other strains, and this is what it is doing in these backyard farms. They should be banned. Intensive agriculture is not a problem for avian flu b/c it is in contained, closed spaces. Intensive agriculture is bad for other reasons, but is not involved in the current avian influenza. If you want to write to you congressman on why intensive agriculture should be banned for health purposes, cite Antibiotic resistance in Enterococcus and Staphylococcus species (in the US) and Menangle virus, Nipah virus, Argentine and Bolivian Hemorrhagic fevers, and Laguna Negra virus (internationally).

Guest guest Posted February 8, 2006 Report Share Posted February 8, 2006 Hi, I have spoken to many of our state poultry specialists, and they do not agree that backyards flocks are the problem. In fact, they believe that backyard flocks are more isolated and the animals are kept in better conditions, and as a result are low risk. In California, they are doing heavy surveillance in areas where there are many commercial farms. Other areas, such as Santa Cruz County, where there are large numbers of backyard flocks, are considered low risk by our state avian specialists. One of the vets told me that it is literally impossible to keep a commercial poultry farm biosecure. They can only reduce the risk. One of the most biosecure facilities in California had a disease outbreak, and it discouraged many other people who ran commercial poultry operations, because they thought, well, if they can have a disease outbreak, what about me who is doing less? Viruses can be carried inside the facility even in the nostrils or ear cannals of workers. These birds are also kept in such terrible conditions and are so packed together, that it really doesn't take much for a disease to take hold and for a virus to be able to mutate rapidly. They say it literally takes hold like wildfire. Further, there are many pathogens that are more of a problem when the dose to the host is very high. For example, one of the hens that I had that was rescued from an egg farm passed away, and I sent her to the lab for a necropsy. It appears that she died of a newly discovered form of avian hepatitis (not transmissable to humans) that about a third of the world's population of chickens have been exposed to, but few ever get. After reading some research papers about it and contacting a researcher studying it, I found out that there is a much higher incidence of a chicken contracting the disease if the feces-to-mouth ratio is high. These birds were covered in feces. One of the state vets told me that in China, they actually have workers sleep on hammocks in the facility with the chickens! In addition, China discovered this virus many years ago and told no one, and gave it time to grow stronger. Another issue that hardly ever is mentioned is that this virus is circulating in poor countries where people might eat poultry even if it is sick or dead, because they need the food. Here are some articles with Dr Gregor: Coming Home to Roost: Bird Flu, a Virus of Our Own Hatching http://tinyurl.com/doqw8 Bird Flu Coming Home to Roost The Satya Interview with Michael Greger http://www.satyamag.com/feb06/greger.html There is plenty of evidence that inhumane farming practices cause pathogens to grow stronger. They should ban the practices that encourage these pathogens, not penalize the people affected by them. I also think it's suspicious that they don't ban cats, which have plenty of close contact with humans and are known to contract bird flu by eating infected wild birds.

Guest guest Posted February 9, 2006 Report Share Posted February 9, 2006 Avian influenza is a controversial topic as are many diseases. It has a complex pathogenesis including many different viruses in different species. There are plenty of differing opinions out there which may or may not be the most informed. The risk of avian influenza infection in commercial farms is lower than in smaller backyard operations because of enhanced housing and biosecurity. Commercial operations are electrically lit and ventilated and completely enclosed, so poultry have no contact with migratory birds. Also, if it does somehow manage to enter, it is contained by physical barriers. Smaller outdoor flocks have a higher risk of infection because the flocks could mingle with wild migrating birds carrying the virus and then pass it onto other species (humans, cats, pigs, etc.) The prevalence of this practice in SE Asia is one of the main reasons why new outbreaks of avian flu start there and not other parts of the world (see outbreaks of 1918, 1957, 1968...) Migratory birds are reservoirs (asymptomatic carriers of the disease) that may move it across the world, but would you want a mass culling of all these birds because they spread the virus? I would hope not. Therefore, why would we want to kill all cats? Cats are not the primary host so controlling them would not control the disease outbreak.

Guest guest Posted February 10, 2006 Report Share Posted February 10, 2006 I'm not for culling any animals due to bird flu, unless they already have it. Nor am I for killing wild birds, even if they do have it. Banning all backyard poultry in the country does not remove the virus from the country, or the potential for infection. Bird flu virus can be in wild birds, cats, other types of pet birds, and it can enter so-called " biosecure " facilities. If it does get into a commercial facility, it has the potential to infect huge numbers of birds all at once. There are many ways that viruses are spread. It can even be carried by a thick fog. When exotic newcastle's infected southern California, the areas most affected were those with large concentrations of poultry, where bird houses were next to each other. Those people with more isolated facilities were less at risk. If there is an infection in a small flock that is isolated from other flocks, there is much less potential for that infection to spread. That is why they are doing heavy surveillance in counties with large numbers of poultry, and they really aren't that concerned with areas that have large numbers of backyard flocks. These flocks are often more physically isolated. The entire world uses multi-species farming practices. Small farms often house multiple types of farm animals in one barn. In fact, one of my favorite chicken books shows a picture of pig who lives with the chickens. Think of a family farm with a few farm animals, ala Babe, and you've got a good picture of how a lot of farms in this country keep farm animals. There are also new multi-species pastured systems in use in this country. There are other factors besides keeping multiple species together that create these viruses. I've heard the opinion expressed that China could have stopped the spread of this virus a long time ago before it became a strong virus and a big problem, and they didn't. There are AI outbreaks in this country, too, but they are quick to control them. In addition, even if you are a poor farmer, people in this country don't tend to eat a sick or dead bird, but in countries with more poverty, they might. Someone recently told me about a trip to China where a small wild bird ran into a window of the bus they were travelling on. People ran off the bus so they could get to the bird first and eat it for dinner! A wild bird can have bird flu, too, you know. Europe has published guidelines for people who have backyard poultry flocks so they can build housing that keeps out wild birds. They are already selling chicken runs that meet these guidelines. Many months ago, I spoke with several of our state poultry vets, and the person who is constructing our bird flu plan for California, and I asked them, what can I do to prevent my chicken and ducks from being killed by the government if bird flu comes here? I spent hours speaking with them and they told me exactly what I needed to do to implement biosecurity for my own flock. I also sponsored a talk in my community to tell people how to implement biosecurity for their flocks, and my new chicken run is under construction right now. If you can demonstrate that you have implemented biosecurity, in California, if there is a disease outbreak in your area, they will most likely test your flock before killing it. But only California and a few Eastern states have the ability to test large number of birds for bird flu. The others do not. There are several things that concern me about our response to bird flu. First, they are not doing a good job of educating the public. For people with backyard flocks, it could take a considerable amount of time and money to construct a covered run. Further, the state has not put together plans that people could use to create these runs in a cost-effective manner. They also aren't widely distributing literature about biosecurity so people can start implementing it. A man at my local feedstore has had chickens for years, and has some flocks whose members are 15+ years old. He has implemented biosecurity for their whole lives. How did he find out about it? A state rep travelled to the feedstore and gave a presentation, and left literature for everyone who came in the store. Why on earth aren't they doing that now? I have been researching chicken run designs since October, and only now do I have a viable one that is being built. Senator Maldonado contacted the state dept of agriculture on my behalf, and they said their policy was that if the bird flu arrived here, they would tell people what to do then. At that point, it is largely too late. People need to build their biosecure housing now. The bird flu has just spread to Africa and the Middle East, and the Iowa futures market has given it a 50-50 chance of being in the US this year. Chickens have been evolving as our companions since about 3200 BC. There is a tremendous variety of breeds, and many, many endangered breeds that are almost extinct. Everytime they go into a country and kill off all the poultry, they are hurting the genetic diversity of poultry and perhaps wiping out entire breeds that have been around for centuries. They are leaving us with the " mutant " breeds that they keep in commercial farms, that would have a hard time making it on a normal family farm. People get upset at the prospect of killing off a large number of cats, but they barely think at all about what it means to kill off an entire country's poultry population. Is someone's pet chicken less important than someone's pet cat? If bird flu comes to this country, I will not get rid of my backyard poultry. By then, they will be in bird-proof covered runs and my cats will be inside. But, I probably will feel a little uneasy when I'm outside gardening with the wild birds who are pooping everywhere. Let's face it, at this point, they are just trying to slow its spread enough that they can develop a vaccine in time. And third-world countries, who probably won't have as much access to the vaccine, will be screwed. Again. Hopefully, it won't develop into a strain that can pass readily from person-to-person.
