Anoxia – Applying the technique

Anoxia technique

High expansion foam

The Anoxia technique is unique for creating an environment without oxygen under atmospheric circumstances. High expansion foam is produced by mixing nitrogen, a mixture of water and specially developed high expansion detergent. The expansion rate is upto 1:1000, meaning that 1 litre of water/foam agent mix expands up to 1 m3 foam. Due to the specially designed foam generator, the high expansion foam bubbles are filled with a > 99% concentration of nitrogen. Therefore, the oxygen level surrounding the animal drops from 21% in atmospheric air to < 1 % once the animal is submerged in the foam.

Convulsions, but no stress or pain

The animals need a constant supply of oxygen to the brain. Applying Anoxia foam, the oxygen is replaced by nitrogen. As a result the nitrogen level is raised to > 99% and the oxygen level is lowered to < 1%. Considering the natural reaction to sudden lack of oxygen the animal is rendering quickly into unconsciousness. As a consequence, behavioral indicators like loss of posture and convulsions will appear. With this in mind, unconscious animals are insensitive to perceive unpleasant sensations like pain.

How Anoxia foam is created

First of all, a mixture of 97% water and 3% high expansion foam agent is sprayed into the Anoxia foam generator, creating a thin film on the outlet of the generator. At the same time, nitrogen is added with overpressure into the foam generator. The nitrogen expands when it exits the generator. This creates a robust high expansion foam. The high expansion foam bubbles are filled with > 99% nitrogen.

Single foam generator systems

In practice, one Anoxia foam generator creates a volume of up to 750 liter of high expansion foam per minute. This volume is more than sufficient to fill a wheelie-bin container within 30 seconds. The most common container volumes are:

 

  • M size – 240 liter;
  • L size – 340 liter;
  • XL size – 370 liter

The choice of the volume of the container depends of the size of the animal and/or the number of animals that need to be stunned/killed. A lid with a chiffon seals the container. As soon as the foam exits the chiffon, the gas supply is stopped and the chiffon is closed. The nitrogen gas concentration in the container remains at 99%.

Revolutionary new stunning method launched on the EU market

anoxia-presentatie-foto-3-overviewCelle, December 22, 2016, by Harm Kiezebrink

Revolutionary new technique

After 10 years of research & development a revolutionary new stunning technique is introduced. Based on the principles of animal welfare as described in the Terrestrial Animal Health Code of the International Standards of OiE: The Anoxia technique – stunning and killing animals by placing them under atmospheric conditions in an environment without oxygen. The solution is not only simple and safe and cost-efficient; it is also not physically demanding to the farmer and his employees.


Animal welfare

The principle guarantees that the animal(s) are placed in an environment with pure nitrogen, once the high expansion foam, filled with 100% nitrogen, replaces the atmospheric air inside the container. From that moment on, the animal inhales pure nitrogen, an atmospheric gas that all living species are used to and that can be inhaled without any physical reactions because atmospheric air contains 78% nitrogen that is inhaled by every breath.


Simple technique

The newly developed and patented technique is simple. All it needs is a soap dispenser connected to a water tap; a soap concentration; a bottle of pure nitrogen including a regulator; a standard waste 240/340/370 liter wheelie-bin container; and the Anoxia lit that closes and seals of the container. Inside the container, a high expansion foam generator is placed, connected to the water/soap and nitrogen through flexible tubes, connected to the inside of the lid. A chiffon is added to the lid, in order to allow atmospheric air to escape the container when it is filled with foam.

Standard Operating Procedure

According to the Standard Operating Procedure, the water/soap and the nitrogen tubes are connected to the electrical valves on outside of the Anoxia lid. Then the animal(s) are placed in the bin, next to the foam generator. The lid is closed and the foam production is started.


Stunned within 30 seconds

After 30 seconds, the container is filled completely with foam. At the moment that the foam is placed in the container via the chiffon, the foam production is stopped and the chiffon is sealed off. Throughout the foam production process the animals remain calm. The high concentration of nitrogen replaces the oxygen in the blood and via the longs; nitrogen is transported to the organs instead of oxygen. The first organ that reacts is the brain that immediately shuts of consciousness.

Body reactions

The contractions of the muscles start after the brain is no longer able to control the movements of the muscles and is not a sign of stress, like with traditional gas stunning methods, where oxygen is gradually replaced with gasses like CO2 or Argon.
Therefore the Anoxia technique is the revolutionary alternative for existing stunning methods that are based on the use of CO2, electrocution, neck dislocation, captive-bolt, as well as killing methods like de-bleeding and maceration.


Anoxia applications

Several applications based on the Anoxia principle are now introduced for:
1. Stunning and sick and cripple killing piglets less than 5 kg
2. Stunning and killing of sick or cripple poultry (especially poultry > 3kg) who need to be killed on the farm by the staff for welfare purposes (avoiding unnecessary stress or pain)
3. Stunning and killing poultry that arrives on the slaughterhouse but that are unfit to be slaughtered (due to injuries occurred during transportation – providing signs of possible illness etc.)
4. Stunning and killing of male pullets at the hatchery
5. Stunning and killing of half-hatched chickens and embryos in partly-hatched eggs, before destruction
6. Stunning and killing parent stock poultry
7. Killing of animals that has been stunned (captive bolt – blow-on-the-head method, etc.) replacing killing by de-bleeding
8. Culling of ex-layers
9. Culling of poultry for disease control purposes


Sales started December 2016

The first application that’s introduced on market in Germany, Holland, Sweden and Denmark can be applied for Stunning and killing piglets less than 5 kg; – poultry > 3kg (turkey and parent stock); and embryos in partly-hatched eggs.

Korea’s response to birdflu outbreaks complete fail: Disaster for poultry industry

sanatizing-rivers [at the picture – Large mobile sprayers spew sanitizers into Seongho Reservoir in Icheon, Gyeonggi, on Thursday, to prevent highly pathogenic avian influenza from spreading in the region.] Published at December 15, 2016 in the Korean Joonang Daily.

Avian Influenza in Korea

It’s official – the H5N6 avian influenza (AI) virus that touched down in Korea one month ago. It has caused the largest amount of damage the domestic poultry industry has ever experienced with bird flus. That’s 284 farms hit, nearly 15 million ducks, chickens and quails culled, and more to go. No other AI virus in the past has killed this many birds. Egg prices are soaring, now fixed at around 6,580 won ($5.63) per tray of 30 at the largest discount retail chain, E-Mart. Paris Baguette raised prices by an average of 6.6 percent earlier this month, their first hike in almost three years.

According to local experts, the crisis will last through April 2017 unless the government dramatically reforms current measures, which have been criticized for being far too weak. In an article published Tuesday, the Korea JoongAng Daily wrote that the first major government meeting discussing the outbreak was not held until one month after the virus was discovered on Oct. 28 in Cheonan, South Chungcheong, in the feces of migratory birds. By then, it had been a week since it reached nearby farms.

Measurements

On Wednesday, the Ministry of Agriculture, Food and Rural Affairs announced that it would “negotiate” whether to raise the national AI crisis level to the highest of the four-tier system, from the current level 3. On Thursday it was upgraded. “Things can really get worse unless the central government closely collaborates with regional governments and farms,” said Seo Sang-heui, a veterinary medicine professor at Chungnam National University in Daejeon.

Kim Jae-hong, dean of the College of Veterinary Medicine at Seoul National University, warned that for the domestic poultry farming industry the next one to two weeks will be a matter of “life or death.” One problem is that regional governments are not doing enough to quarantine areas, due to a lack of human resources and money. In a recent investigation by the Ministry of Public Safety and Security, there were 20 cases in which a government office wrote on official documents they set up an AI control team for their communities, but did not actually do so.

In Sejong City, a farmer was caught shipping off 100,000 chickens to his retailers last month and reporting to the government the next day that his farm appeared to be hit by AI. It later tested positive and authorities are now investigating whether he had known about the infection ahead of time. In a country where the government relies on farmers to report viruses on their own, and punishes those who turn out to have failed to take proper quarantine measures in the first place, many farmers hesitate to report their circumstances. Moreover, movement bans are imposed on poultry farmers and their vehicles at locations where the virus has tested positive, but rarely are these restrictions taken seriously.

Choe Nong-hoon, a veterinary medicine professor at Konkuk University in Seoul, thinks it is time for Korea to reform its entire poultry farming industry as current circumstances will only attract more forms of AI in the future. In Korea, chickens are normally raised in a closed, artificial setting, Choe said, as opposed to European countries and Japan, where free-range farming is more common. Free-range farming is more expensive, but cheap goods can be replenished by foreign imports, said the professor. “It’s about time to negotiate changes in related policies not just for Korea’s poultry industry,” Choe said, “but for the sake of public health.”

H7N9 Pandemic?

Published at 15 December 2016 in The Standard Hong Kong, by Mary Ann Benitez and Carain Yeung.

World Health Organization director- general Margaret Chan Fung Fu-chun warns bird flu H7N9 is particularly worrying as it could be a flu pandemic strain. This is because H7N9 is unique as it does not make chickens sick but is deadly in humans. Sick birds could usually provide early warning for imminent outbreaks, Chan told The Standard. This comes as Macau reported its first human case of H7N9 yesterday. “The biggest challenge for the world is the next influenza pandemic,” Chan said.

Fear of African Swine Fever triggers biosecurity step up

Fear of African Swine Fever triggers biosecurity step up

ASF is considered a major threat to Danish pig producers, largely due to its presence in locations of export and its highly contagious nature. With the industry continuously under strain to make sure extensive measures are in place to safeguard the country from the disease.

 

 

 

Danish prevention plan

Soren Sondergaard, vice-chairman, of SEGES Pig Research Centre, said that ASF prevention utilised a massive amount of the annual budget but was necessary as an outbreak could cost the sector billions of kroner.
New regulations have been implemented to mitigate the risk, including new regimes which call for trucks to be thoroughly cleaned and held in a restricted area for a certain amount of time between transportation.

Mr Sondergaard said: “We are spending between 15-18 million Danish krone a year on cleaning the trucks, and have hired trained staff to do so, minimising the pressure on the drivers. If trucks are transporting to regions where ASF has been recorded, the vehicle must be cleaned and then left for seven days before returning to Denmark. We are working very hard to prevent an outbreak as it would cause devastation to our industry and economy as a whole.”
In the event of an ASF spread, parts of Denmark would be closed off with immediate effect, in order to ensure the flow of production could still continue in other areas.

As the virus is a noted problem in countries with vast numbers of wild pigs, Mr Sondergaard suggested that culling regimes could be another option to consider, as well as changing the drop off points where live animals are exchanged.
He said: “In risk areas such as Poland, it would be ideal to transport animals to Russia and then arrange collection so our trucks do not have to drive on the infected land. However, this would be expensive and so more safeguarding action needs to be developed.”

New outbreaks of avian influenza in Europe

New outbreaks of avian influenza in Europe

New outbreaks of avian influenza have been reported among wild birds and poultry across Europe since the end of October 2016. The highly pathogenic avian influenza (HPAI) H5N8 virus is identified in Hungary, Poland, Croatia, Germany, Austria, Switzerland, Denmark, and the Netherlands.

EFSA investigation

EFSA experts are supporting Member States in their data collection activities. These collections are aimed at identifying how the virus enters poultry farms and the risks posed by wild birds. This information will help EFSA to re-assess the risk of introduction of avian influenza into the EU. The risk assessment is based on new scientific knowledge. The updated scientific advice will be published in 2017.

The European Commission has called on Member States to be vigilant and to reduce the risk of further outbreaks. They will do so by taking measures such as increasing biosecurity levels in poultry holdings and backyard flocks.

EFSA has worked on this topic extensively in recent years. Its work has included a scientific opinion on migratory wild birds and their possible role in the spread of highly pathogenic avian influenza viruses.

Dossier Ventilation Shutdown: How to Kill Half a Million Chickens at Once

Published on February 9, 2016 on Motherboard.vice.com, Written by Kaleigh Rogers. You’d be hard pressed to find someone who would argue that killing a flock of chickens by shutting down ventilation systems to their barn and letting them slowly overheat and suffocate is a pleasant way to go. In fact, a year ago, this method of killing sick birds—called ventilation shutdown—was not permitted by the Department of Agriculture. But after a devastating bout of highly pathogenic avian influenza (HPAI) decimated US chicken and turkey farms last year, the USDA approved and has started using this controversial killing technique to cull infected flocks at massive, commercial farms in an effort to prevent another outbreak.

Nobody is keen on killing hundreds of thousands of chickens at a time—aside from it being a grim task, it also results in a huge loss of revenue—but it’s a necessary evil to shut down disastrous outbreaks. The USDA acknowledges that ventilation shutdown is not a great way to go, though a representative told me the agency can’t say for sure how long it takes birds to die this way. The fact that the USDA would resort to a killing technique most experts agree is less-than-ideal at best and inhumane at worst, without fully understanding what this method does to the animals, shows how ill-prepared we are for dealing with a massive agricultural epidemic. If we want to be more prepared in the future, shouldn’t the USDA be looking for better ways to kill half a million birds at once?

When a flock of poultry is infected with HPAI, swift action is imperative. As long as the birds are alive, they actively shed the live virus through their feces and saliva, which increases the risk of the disease spreading to other farms. So when the virus is detected, the USDA requires the flock to be depopulated—a term meaning the mass killing of livestock in response to a disease outbreak—within 24 hours. In some cases, like on some turkey farms in Indiana last month, this means resorting to ventilation shutdown.

“I don’t think anyone denies that there are more welfare challenges with ventilation shutdown than any of the other techniques,” said Maurice Pitesky, a veterinarian and expert in poultry epidemiology at the University of California. “But if you’re just thinking solely about how to depopulate the flock, ventilation shutdown is the quickest way to do that.”

It’s true that, from a procedural standpoint, ventilation shutdown is the option that can be executed most quickly. Other methods, like gassing the birds with carbon dioxide or suffocating them with a dense CO2 foam, require more time to orchestrate: you have to find a way to get a CO2 tanker to the farm, pump the gas into the barn, and wait for the concentration to get high enough to depopulate the flock. Depending on the location and size of the farm, this could take more than 24 hours to complete—beyond the USDA’s deadline. Ventilation shutdown, on the other hand, is just a matter of flipping a few switches.

The USDA guidelines for ventilation shutdown are to turn off the ventilation systems, then raise the temperature inside the barn to at least 104F for a minimum of three hours. This can be done by turning up the temperature, but because the barns are so densely packed they can sometimes heat up that much just by virtue of the air systems being shut off. It’s happened in the past by accident, when pranksters shut off power or electrical failures cause the air systems to shut down. From start to finish, the actual process is the quickest way to depopulate a flock.

The trouble is that, for each individual bird, it might be one of the slowest and most painful ways to die. Paul Shapiro, vice president of farm animal protection for the Humane Society of the United States, described the process as “essentially baking the birds to death,” and called it “horrific.”

The HSUS claims it could take birds hours to die through ventilation shutdown, but there are no studies that have looked at the time to death with this method. USDA officials have previously estimated the process takes 30 to 40 minutes to kill birds, but when I reached out to the agency, it couldn’t confirm how long it takes birds to die this way.

“The majority of birds will die quickly, but it is advisable to maintain the recommended temperature for three hours to account for poor heat distribution and, importantly, inactivate much of the HPAI virus in the poultry house,” Andrea McNally, a spokesperson for the USDA Animal and Plant Health Inspection Service, told me, stressing that ventilation shutdown was considered a last resort option. When I asked McNally to clarify what the USDA considered “quickly,” she said she couldn’t.

“The variabilities of structures and density of poultry make it hard to give you an easy answer,” McNally said.

It’s not all that surprising that the USDA doesn’t know precisely how long it takes birds to die via ventilation shutdown, because nobody really does, according to Patricia Turner, a veterinarian and pathobiology professor at the University of Guelph who has researched depopulation methods and is a consultant on the American Veterinary Medical Association’s depopulation panel.

“It hasn’t been studied, to be very honest,” Turner told me over the phone. “You want the animal to become insensible as soon as possible. The time to death is pretty rapid with ventilation shutdown, within probably 10-25 minutes depending on the size of the barn. The problem is that we don’t know what the animals experience in that time.”

One of the arguments in favor of using ventilation shutdown is that if farmers delay in an attempt to use another method like CO2, the virus could spread, putting even more animals on death row. But if there are other, potentially more humane methods, why aren’t we set up to put them in place quickly if needed?

“It’s unheard of, the methods they’re applying,” said Harm Kiezebrink, an expert in humane poultry depopulation who has developed painless slaughtering technology. “Anybody with a little common sense understands that if you don’t research animal welfare for a method that is now the standard, that is very, very bad.”

Kiezebrink has worked around the world to help governments manage avian influenza outbreaks, depopulating farms from the Netherlands to China. Ventilation shutdown isn’t widely used in other countries, according to Kiezebrink (gassing is usually preferred). It was green-lit in the UK in 2006 but never implemented. It’s far from the most gruesome depopulation method around—in the past, some countries have resorted to burning or burying birds alive—but Kiezebrink said the lack of understanding of the method’s effect on birds should rule it out, at least until further research is done.

But other options aren’t cheap. The technology Kiezebrink once marketed—including a machine that kills birds instantly by dragging them through electrified water—cost as much as $600,000. Recently Kiezebrink said he’s been researching a nitrogen-based foam that would, he says, basically just put the birds to sleep when inhaled. But this, too, would likely be too expensive to use on a widespread basis.

“Gas-injected foam is better because the animals actually die of lack of oxygen, which occurs much faster and much more quietly—they don’t seem to show the same distress,” Turner told me. “The problem is nitrogen is expensive and difficult to source. For the huge farms prevalent in the US, which are much bigger than anything in Europe, it’s probably not feasible.”

So where does that leave us? The good news is, after the ventilation shutdown in Indiana, there haven’t been any more reports of HPAI so far this year. That buys us some time to work on more humane methods, including potentially developing vaccines, Turner said. She said when the AVMA completes its depopulation guidelines, the USDA will likely need to reassess its use of ventilation shutdown.

“I would be very surprised to see this technique accepted [by the AVMA] without peer-reviewed papers that support it,” Turner said. “In addition to needing data on it, there needs to be public acceptance. You can think of a number of procedures that might be very quick but would not be interpreted to be humane, or that the public just might not have the stomach for.”

Dossier H7N8: Frigid Air Slows Efforts to Euthanize Turkeys in Indiana

 

Frigid Air Slows Efforts to Euthanize Turkeys in Indiana

ABC news online, Jan 18, 2016. Frigid temperatures are hampering efforts to euthanize turkeys at several southwestern Indiana farms where a strain of bird flu was found last week, freezing the hoses used to spread a foam that suffocates the affected flocks, a spokeswoman for a state agency said Monday.

The H7N8 virus was discovered on 10 turkey farms in Dubois County, which is Indiana’s top poultry-producing county, last week.

Temperatures that dipped into the teens and single digits over the weekend stymied efforts to fill the affected poultry barns with the foam to a level just above the turkeys’ heads to suffocate them, said Denise Derrer of the Indiana State Board of Animal Health.
“The water’s been freezing up. It’s slowing things down, but we’re doing the best we can,” she said.

Derrer said state workers, staff from the U.S. Department of Agriculture and others have been using carbon dioxide gas instead of the foam. Other turkeys are being killed manually with a device that delivers a fatal head injury, but that method is slow and inefficient, she said.

While the USDA has a goal of euthanizing infected poultry within 24 hours of the discovery of infected flocks, it’s not a requirement, Derrer said, adding that workers are trying to euthanize flocks as quickly as possible.

As of Monday, nearly 120,000 turkeys had been killed on four of the farms, while efforts to euthanize about 121,000 turkeys continued on six other farms.

The H7N8 strain is different than the H5N2 virus that led to the deaths of 48 million birds last summer, mostly in the upper Midwest.

The first farm where H7N8 was found had a highly contagious form of the virus, Derrer said, but tests by USDA staff have shown eight of the other nine turkey farms have a “low pathogenic” form, meaning the birds are more likely to get sick but not die.

The results also suggest that the outbreaks were caught earlier in the disease cycle before the virus had a chance to mutate and become more virulent.

Test results on viral samples taken from the ninth farm are still pending. All of the affected farms were within six miles of the first one; officials are still monitoring other farms and backyard flocks within that distance, Derrer said.

Dossier H7N8: All flocks in Indiana ‘euthanized’?

All flocks in Indiana ‘euthanized’?

WattAgNet.com, January 21, 2016. Depopulation has been completed at 10 turkey farms with confirmed avian influenza detections and another nearby layer farm deemed at risk. Depopulation procedures have been completed at 11 farms in Dubois County, Indiana, after the presence of H7N8 avian influenza had been detected at 10 of those farms.

According to the Indiana State Board of Animal Health, 413,163 birds have been depopulated since avian influenza was first confirmed in Dubois County on January 15. Of the birds euthanized, 257,163 were turkeys and 156,000 were layer chickens.

Ten of those farms were commercial turkey operations, while the layer operation was not infected with avian influenza. However, the Dubois County layer flock was depopulated as a precaution because of its “dangerous” proximity to the affected flocks.

The first and largest turkey flock to be affected was confirmed to have been infected with highly pathogenic H7N8 avian influenza, while nine others were confirmed to have been hit by a low pathogenic strain of H7N8. The other turkey flock tested positive for the presence of H7N8 avian influenza, but it has not yet been determined whether it was a highly pathogenic or low pathogenic strain.

The flock hit by highly pathogenic avian influenza included 62,213 turkeys.
The bird carcasses from those farms are being composted in the buildings in which they were euthanized.

The Indiana agency reported that during a 24-hour period that started on January 19, 114 commercial farms tested negative for avian influenza. Of those, 62 farms were in the initial 10-kilometer control zone, while the others were in an expanded zone that covered an additional 10 kilometers. The expanded zone includes not only Dubois County, but also Crawford, Daviess, Martin and Orange counties.

State and federal teams have visited nearly 1,600 residences near the site where the first confirmed avian influenza case occurred to search for backyard flocks for precautionary testing. The teams found 67 backyard flocks within that area, and those birds are being tested.

Dossier H7N8: USDA APHIS confirmed outbreak on commercial turkey farm in Dubois county, Indiana

Avian Infuenza in Indiana

Bloomberg Business online, January 15, 2016. The U.S. Department of Agriculture said it confirmed the diagnosis on January 11, 2016, the presence of a highly pathogenic strain of avian influenza in a commercial turkey flock in Indiana, the country’s first case since the end of last year’s outbreak that led to the destruction of 50 million animals.

The H7N8 strain discovered at a 60,000-bird flock in Dubois County is different from those that caused last year’s outbreak, the U.S. Department of Agriculture’s Animal & Plant Health Inspection Service said Friday in a statement on its website. Federal and state authorities are monitoring and testing the nearby area, it said, without naming the exact site.

The USDA contacted countries that buy poultry and eggs after the detection and hasn’t received any notice of official import restrictions, T.J. Myers, associate deputy administrator at the inspection service’s APHIS, said on a conference call with the media. The USDA is working to “minimize the trade impact,” Myers said.

U.S. poultry producers have been on edge after recent cases in France. The 2015 U.S. outbreak, which ended in June, led to record-high egg prices and caused some shortages of turkey deli meat used in subs and sandwiches. It cost the industry $3.3 billion.
Rapid Response

Producers have been discussing the new outbreak in a series of conference calls since they first became aware of the Indiana case late Thursday, said John Brunnquell, president of Egg Innovations LLC, which produces free-range eggs in farms across the Midwest. The response has been rapid, with the killing of birds going on throughout the night, he said in an interview.

“The timing of the disease was a surprise because most in the industry did not think it would reappear for another two or three months,” said Terry Reilly, a senior commodity analyst for Futures International LLC in Chicago.

Preliminary tests indicate the H7N8 strain found in Indiana was of North American origin, according to the USDA’s Myers. The USDA will conduct diagnostics to seek a cause for the mutation of the virus, he said.
Different Strain

Determined to avoid a repeat of the nation’s worst-ever avian-influenza outbreak, the USDA stockpiled millions of doses of a new vaccine designed to fight the 2015 strain, which is different than the one in Indiana, Myers said.

“Concerns are huge, but we cannot pull the panic button until we know quite a bit more,” said Bill Lapp, the president of Advanced Economic Solutions in Omaha, Nebraska. “Because it is found in a different state, and is a different strain, it makes an even greater mystery.”

Sixty-five egg and turkey farms are within 10 kilometers (6.2 miles) of the affected barn, said Brunnquell of Egg Innovations. The area is home to an estimated 4.5 million egg-layers and about 1 million to 2 million turkeys.

Producers within 10 kilometers of the affected barn can’t move products or animals without testing to determine if they are free of the virus, Denise Derrer, a spokeswoman for the Indiana Board of Animal Health, said in a telephone interview.
Testing Birds

The affected producer began terminating birds in nine other barns on the farm after tests showed the virus was highly pathogenic. A bird flu test conducted by a Purdue, Indiana, laboratory came back positive yesterday, Derrer said.

No other signs of the virus have yet been detected, she said. Government teams will travel to the area to contact people raising backyard flocks on Saturday to test more birds.

Indiana’s poultry industry ranks fourth nationally in turkey production, first in duck production and third in eggs. It also is a significant producer of broiler chickens.

Shares of poultry producer Pilgrim’s Pride Corp. closed 5.2 percent lower in New York, the most in three months. Tyson Foods Inc., which produces chicken and other meats, fell as much as 5.5 percent before closing down 2.7 percent.

The case of avian flu in Indiana doesn’t involve Tyson, Hormel Foods Corp., Cargill Inc., Maxwell Farms LLC’s Butterball or Sanderson Farms Inc., according to company e-mailed responses.

The news of the case of bird flu was a boost for Cal-Maine Foods Inc., the largest U.S. egg supplier. Its stock jumped as much as 11 percent before closing up 5.2 percent.

Avian influenza doesn’t present a food safety risk. All shipments of poultry and eggs are tested to ensure the absence of avian influenza before moving into the food supply. The Centers for Disease Control considers the risk of illness to humans to be very low.
