Minnesota H5N2: 55 Farms Affected Across 18 Counties

# 9985

 

 

APHIS  has updated their website, and has added six more outbreaks, from four states (IA, ND, WI & MN) this evening, but it is still running several days behind many of the state’s local announcements. 

 

Wisconsin announced their 6th outbreak on Friday, but the USDA’s list still shows only 4.  Similarly, Minnesota has reported 55 outbreaks, but only 52 are listed.

We do have a recent update from Minnesota’s Board of Animal Health, and they are now reporting 55 farms in 18 counties have now been hit with the avian flu.  Up from 49 farms spanning 17 counties on Friday.

 

The good news is that we haven’t seen any fresh outbreaks reported from the lower latitude states (Missouri, Arkansas, Kansas) in several weeks, which many attribute to the recent arrival of warmer weather.   

 

As temperatures climb in Minnesota, Wisconsin, and Iowa the hope is that the level of bird flu activity will decrease there as well.

APHIS: 3 More Minnesota Farms Hit By HPAI H5N2, 1 In Wisconsin

HPAI H5 Detections In North America

 

# 9977

 

We seem to be getting into a pattern where individual states are announcing outbreaks, but those reports are taking a couple of days to show up on the USDA’s APHIS website. 

 

Case in point, as of yesterday Wisconsin was reporting 6 outbreaks, yet this evening’s APHIS update still only shows 4, and yesterday’s reported outbreak in Sac County, Iowa has yet to appear on their list. 

 

It may be that APHIS is waiting for full subtype information to to come back from the lab before posting.

 

In any event, APHIS announced three new outbreaks today in Minnesota, and one of the  Wisconsin cases we learned of yesterday morning.   Given the volume of testing going on - including ongoing surveillance of flocks within the quarantine zones surrounding infected farms - it is little wonder that the release of data is at times erratic.

 

 

Although the APHIS tally lists 7,837,073 bird now affected, there are a several farms where the numbers are still pending, and several other farms that the states have announced as being infected, but are not yet listed. 

 

All of which means the real number is probably in excess of 8 million birds by now, and still growing.

Iowa, Wisconsin & Minnesota Report Additional HPAI H5 Outbreaks

 

# 9972

 

The new bird flu ritual, which began in earnest earlier this week, is waiting for the daily update from the USDA’s APHIS avian flu website, which tends to come in sometime after 5pm EDT.   Today that update has been running considerably later than usual. 

 

However, earlier today the state of Wisconsin announced a Second avian influenza detection found in Barron county commercial turkey facility, bringing the number of outbreaks in that state to 6, involving 1.2 million birds.

And in the past few minutes the state of Iowa released a statement regarding their third HPAI outbreak.

 

CASE OF HIGHLY PATHOGENIC AVIAN INFLUENZA IN SAC COUNTY, IOWA
CDC considers the risk to people to be low

DES MOINES – The Iowa Department of Agriculture and Land Stewardship is responding to a case of highly pathogenic avian influenza (HPAI) in a commercial turkey flock in Sac County, Iowa.   The facility has 34,000 turkeys and is within the 10 kilometer monitoring zone surrounding the initial HPAI case in Buena Vista County.  This is the third case of HPAI in Iowa.

The flock has experienced increased mortality and samples have been sent to the Iowa State University Veterinary Diagnostic Laboratory.  Preliminary results showed the birds positive for an H5 strain of avian influenza.  Samples were then sent to the APHIS National Veterinary Services Laboratories (NVSL) in Ames, Iowa to further confirm the findings.

State officials quarantined the premise and birds on the property will be humanely euthanized to prevent the spread of the disease.

 

In the past couple of hours, amid media reports that a large chicken farm in Becker County has also been hit,  we’ve seen Minnesota Governor Dayton sign an executive order declaring bird flu an emergency. As of this writing nothing has been posted on the Governor’s website, but the Minnesota Board of Animal Health has posted the following statement:

 

In Response to Avian Influenza, Governor Mark Dayton Issues Emergency Order Declaring Peacetime State of Emergency

Executive Order activates Minnesota Emergency Operations Plan to respond to Avian Influenza

ST. PAUL, MN – Governor Mark Dayton today issued Emergency Executive Order 15-09, declaring a Peacetime State of Emergency in Minnesota in response to the discovery of H5N2 avian influenza cases statewide.

Under the Governor’s Executive Order:

• The Division of Homeland Security and Emergency Management (HSEM) will activate the Minnesota Emergency Operations Plan to support the efforts of the Minnesota Board of Animal Health and the Minnesota Department of Agriculture, to coordinate response efforts across all agencies of state government.

• Supplementing Emergency Executive Order 15-06 extending relief to certain motor vehicle drivers and carries pertaining to hours of service, in addition to the previous exemption of weight restriction.

• And the Adjutant General of Minnesota will order to state active duty such personnel and equipment of the military forces of the State as required, and for such a period of time as necessary to provide assistance and emergency relief services.

 

While stating that Animal health officials are currently investigating possible additional cases of HPAI in Minnesota flocks,  the Minnesota Board of Animal Health only lists two additional farms on their list tonight.  Not included is the Becker county chicken farm mentioned above.

 

At approximately 6:30 EST APHIS updated their HPAI listing, but only included the two  Minnesota outbreaks mentioned above.  They still only show three outbreaks in Wisconsin – when the Wisconsin website is already reporting six, and they have no update on the Iowa outbreak. 

Hopefully we’ll get caught up with those in tomorrow night’s update. 

 

As has been advised by the CDC since late January (see CDC Interim Guidance On Antiviral Chemoprophylaxis For Persons With Exposure To Avian Flu) Minnesota is offering antivirals to poultry workers who have been exposed to these high path viruses. 

 

So far, however, we’ve seen no evidence that the North American reassortant H5 viruses are able to infect humans, but these steps are recommended out of an abundance of caution.

 

This from the Minnesota Board of Animal Health.

 

Poultry Workers

MDH is monitoring the health of workers, who have had contact with infected poultry, and providing guidance on infection control, the use of personal protective equipment, and providing support for any other health-related aspects of response.

• People who had close, unprotected contact with infected flocks are recommended to receive an antiviral drug called Tamiflu.
• Workers are then contacted daily for 10 days and monitored for development of respiratory symptoms.
• As of today, MDH has completed follow-up contacts for 41 flocks.
• In total, 140 people had been involved in care of the 41 flocks and were interviewed and evaluated.
• MDH is currently monitoring 78 poultry personnel for potential symptoms of infection, such as development of an eye infection or respiratory symptoms.
• The MDH 10-day monitoring period has been completed for 62 people and 14 flocks; no infections with this virus were detected.

 

 

And so the bird flu beat goes on for another day . . . .

APHIS: 13 More Minnesota Turkey Farms Hit By H5N2, 2 More In Wisconsin

 

# 9969

 

The news keeps getting worse coming out of Minnesota, where now 44 turkey farms have reportedly been hit by the highly pathogenic H5N2 virus. Thirteen of those farms were announced today on the APHIS website, and while the count of birds on several of the farms is pending, the known number of birds affected increases by at least 400,000.

 

 

Meanwhile there are reports, not yet appearing on the APHIS website, of two more farms in Wisconsin being hit by the virus. This from the Wisconsin Department of Agriculture.

 

Second avian influenza detection found in Jefferson county commercial egg-laying facility

April 22, 2015

Second avian influenza detection found in Jefferson county commercial egg-laying facility (PDF)

Media Contacts:  Raechelle Cline, 608-224-5005 or Jim Dick, Communications Director, 608-224-5020

MADISON, Wisc.—The Wisconsin Department of Agriculture, Trade and Consumer Protection, in cooperation with the US Department of Agriculture is responding to a detection of H5 avian influenza in an 800,000 bird egg-laying chicken flock in Jefferson county. There are now five cases in Wisconsin.  While lethal to domestic poultry, the strain of virus detected is not known to have caused disease in humans and is not expected to pose a risk to public health or the food supply.

The property was immediately quarantined and neighboring properties with poultry will be notified about the situation.  Remaining birds will be depopulated and will not enter the food supply.  Following USDA protocols, surveillance and testing procedures will take place at properties near the affected facility to ensure the virus has not spread.

The H5 avian influenza virus was first detected in Wisconsin at a commercial chicken flock in Jefferson County on Monday, April 13, which led to the depopulation of more than 180,000 egg-laying chickens.  Since then three additional flocks were detected in Barron, Juneau and Chippewa counties bringing the total of birds destroyed to nearly 400,000 in Wisconsin.  Multiple outbreaks of avian influenza have occurred most recently in Iowa, Minnesota, Missouri, Arkansas, the Dakotas and Kansas leading to the depopulation of more than 1 million turkeys and chickens since January.

Dr. Paul McGraw, Wisconsin state veterinarian, already issued a ban on poultry movement to shows, exhibitions and swap meets in Jefferson, Juneau and Barron counties.  Chippewa county was added to the ban this morning.

Wisconsinites are reminded that the avian influenza virus strain currently detected in Wisconsin and the other states presents low risk to public health. Poultry meat and egg products in the marketplace remain safe to eat. As always, both wild and domestic poultry should be properly cooked.

Officials are investigating how the virus entered the flock and may not have answers for some time.  Until then, backyard poultry owners and other poultry producers are encouraged to practice good biosecurity and to take steps that prevent contact between their birds and wild birds. They also should monitor their flock closely and report sick or dead birds to DATCP at 1-800-572-8981.

APHIS: 3 More Minnesota Farms, 1 In S.D. Hit by H5N2

HPAI H5 Detections In North America

 

# 9966

 

APHIS updated their current listing of poultry farms  hit by the HPAI H5 virus shortly after 5pm today, adding three more turkey operations in Minnesota, and a turkey farm in South Dakota to the rapidly growing list.

 

Today’s announcement brings to 31 the number of farms hit in Minnesota, involving more than 2.1 million turkeys.  This is South Dakota’s 6th farm to be hit, with roughly 286,000 turkeys affected.

Yesterday’s announcement of 5.3 million chickens exposed – and slated to be culled – in Iowa has been rolled back to 3.8 million – which represents more than half of the loses reported to date.

H5N2 Impacts 5.3M Chickens In Iowa, Two More Farms In Minn. - APHIS

 

 

 

# 9963

APHIS updated their current listing of poultry farms to be hit by the HPAI H5 virus shortly after 5pm today, and a farm in Iowa – with 5.3 million chickens either infected or exposed – singlehandedly more than doubles the number of birds on the culling block since the virus began to spread across the United States last December.

 

With the exception of 200,000 chickens affected 10 days ago in Wisconsin, the H5N2 story in American poultry this winter has been almost entirely centered around turkeys.  While considered less susceptible to HPAI H5N2 than turkeys, today’s announcement will no doubt raise additional  red flags for chicken producers across the nation.

The APHIS report also indicates two more Minnesota turkey farms have been hit in recent days, bring that state’s total to 28 farms involving roughly 1.7 million turkeys.

HPAI H5: 2nd Outbreak In Ontario, Changes In APHIS Reporting

HPAI H5 Detections In North America

 

# 9956

From Canada’s CFIA we get word this weekend that a second farm in Oxford County, Ontario has tested positive for HPAI H5 (sub-typing pending) – roughly 11 days after the first farm in the county seat Woodstock was reported infected (see CFIA: H5 Avian Flu Found On Ontario Turkey Farm).

These two southern Ontario detections represent the farthest eastward expansion of the H5 virus we’ve seen this year, although based on its rapid jump from the Pacific Northwest, there is little reason to believe it will stop their.

First the CFIA report, then I’ll return with some change to the way APHIS will now report outbreaks in the United States.

 

Avian influenza confirmed on second farm in Southern Ontario

OTTAWA, April 18, 2015

Preliminary testing by the Province of Ontario has confirmed the presence of H5 avian influenza on a second farm in Oxford County, Ontario. The farm is a broiler breeder chicken farm.

The Canadian Food Inspection Agency (CFIA) has placed the farm under quarantine to control disease spread and the poultry industry has been notified to adopt enhanced biosecurity practices. Further testing by the CFIA is underway to confirm pathogenicity and to determine the precise subtype and strain of the virus. Pathogenicity refers to the severity of the illness caused in birds.

Avian influenza does not pose a risk to food safety when poultry and poultry products are properly handled and cooked. Avian influenza rarely affects humans that do not have consistent contact with infected birds. Public health authorities stand ready to take precautionary measures as warranted.

Initial tests for the disease were conducted on April 17, 2015 at the Animal Health Laboratory at the University of Guelph, after the chicken farm experienced sudden deaths of birds over several days.

All birds on the infected premises will be humanely destroyed and disposed of, in accordance with provincial environmental regulations and internationally accepted disease control guidelines. As lead response agency the CFIA will ensure the quarantine of the infected farm, and determine a surrounding surveillance zone for further testing and movement control measures. The CFIA will also lead on required depopulation of birds, while the Province will provide technical support on required carcass disposal. Once all birds have been removed, the CFIA will oversee the cleaning and disinfection of the barns, vehicles, equipment and tools to eliminate any infectious material that may remain.

The Province of Ontario, the CFIA, the owner of the infected birds, and the poultry industry are working closely together to manage the situation. Both levels of government will work with the poultry industry to address issues as they emerge. The Canadian poultry sector currently practices a high level of biosecurity that reduces the risk of disease spread.

Meanwhile, in the United States these HPAI H5 virus continue to spread, hitting farms from California to Arkansas.  Hardest hit – with 26 turkey farms affected (as of 4/16) – has been Minnesota.  

 

Up until mid-week, the USDA’s APHIS (Animal Plant Health Inspection Service) had been releasing a Stakeholder Announcement for each outbreak, some days resulting in 4 or 5 new statements being issued each day.

 

On Thursday I noted that an outbreak in Roberts County, SD had been added to the list, but no formal announcement had been posted.  The following day, an that outbreak was announced, with the following advisory indicating that because of the sheer volume, Stakeholder Announcements would be henceforth be published for detections in new states, a new flyway, or the discovery of a new strain.

 

Since the beginning of the HPAI H5 outbreaks, USDA has been committed to transparency in announcing these detections. Delivering factual, timely information is a priority for USDA.  Because more detections are expected during the Spring migration, USDA will streamline its announcements through daily GovDelivery messages as well as continue posting the new cases on the APHIS website.  And In the event of HPAI H5 detections in a new state and/or new flyway or detections of new strains, USDA APHIS will issue only a stakeholder announcement and post the findings on its AI website.

 

What we have now is a master list of cases, along with an interactive list that allows the viewer to drill down to any specific state’s information. 

 

In many ways this will be more convenient, although we may not be getting updates in quite as timely of fashion as under the older format. In some cases we may also see instances where states will have reported cases before they appear on the APHIS list.

 

The most recent update to the APHIS master list – current through 4/16/15 – puts the total number of commercial birds affected by these viruses at 2,670,890.

APHIS: Wisconsin Reports HPAI H5N2 In Commercial Chickens

 

# 9933

 

The list of states reporting HPAI H5 continues to expand this morning , with a farm containing 200,000 chickens in Jefferson County Wisconsin the latest to be affected. 

 

Wisconsin becomes the 14th state to report HPAI H5 – in either wild birds or poultry – since the virus migrated to North America last fall.

CDC considers the risk to people from these HPAI H5 infections in wild birds, backyard flocks and commercial poultry, to be low

WASHINGTON, April 13, 2015 -- The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of highly pathogenic H5N2 avian influenza (HPAI) in a commercial layer flock in Jefferson County, Wisconsin.  The flock of 200,000 chickens is located within the Mississippi flyway where this strain of avian influenza has previously been identified. CDC considers the risk to people from these HPAI H5 infections in wild birds, backyard flocks and commercial poultry, to be low.  No human infections with the virus have been detected at this time.

Samples from the turkey flock, which experienced increased mortality, were tested at the Wisconsin Veterinary Diagnostic Laboratory and the APHIS National Veterinary Services Laboratories (NVSL) in Ames, Iowa confirmed the findings. NVSL is the only internationally recognized AI reference laboratory in the United States.   APHIS is working closely with the Wisconsin Department of Agriculture, Trade and Consumer Protection on a joint incident response. State officials quarantined the premises and birds on the property will be depopulated to prevent the spread of the disease. Birds from the flock will not enter the food system.

Minnesota: Four More Farms Hit By HPAI H5N2

 

# 9927

 

The number of commercial turkey operations in Minnesota hit by the HPAI H5N2 avian flu continues to rise, with 4 new farms announced today, making a total of 13. The hardest hit county has been Stearns, which reports its 4th infected farm today.

The three new areas reporting this avian flu virus are Cottonwood, Lyon and Watonwan counties, all clustered in the southwestern part of the state. 

 

According to media reports a team of USDA  epidemiologists arrived earlier this week to help state and local agencies figure out how the virus is spreading to new farms despite the enhanced biosecurity measures that are in place.

 

While migratory birds are strongly suspected of carrying and dispersing the virus along the Pacific and Mississippi Flyways, thus far Minnesota has yet to report finding the virus in any wild birds (see Wild Bird Findings confirmed by USDA’s National Veterinary Services Laboratories).

 

This is today’s announcement from APHIS.

 

 

USDA Confirms Highly Pathogenic H5N2 Cases in Four Minnesota Counties

WASHINGTON, April 10, 2015 -- The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of highly pathogenic H5N2 avian influenza (HPAI) in an additional four commercial turkey flocks in Minnesota.  There are thirteen total confirmed cases in Minnesota.  These flocks are within the Mississippi flyway where this strain of avian influenza has previously been identified. CDC considers the risk to people from these HPAI H5 infections in wild birds, backyard flocks and commercial poultry, to be low.  No human infections with the virus have been detected at this time.

The affected flocks are in:

• Cottonwood County - 48,000 turkeys
• Lyon County - 66,000 turkeys
• Stearns County 45,000 turkeys (4th detection in the county)
• Watonwan County - 30,000 turkeys

Samples from the turkey flocks, which experienced increased mortality, were tested at the University of Minnesota Veterinary Diagnostic Laboratory and the APHIS National Veterinary Services Laboratories (NVSL) in Ames, Iowa confirmed the findings.

APHIS: 2 More Minnesota Turkey Farms Hit By H5N2

 

# 9995

 

The USDA’s APHIS has announced that two more Minnesota farms have been hit by the Highly Pathogenic H5N2 virus, bringing to 7 the number commercial flocks hit so far in that state.  Stearns county, with three farms now reporting the virus, has been the hardest hit.

 

For now – in North America, anyway – the biggest concerns lie with poultry producers. 

 

While related to the H5N1 virus – which has killed several hundred people around the globe – these particular H5 viruses (H5N2 & H5N8) have not demonstrated a similar ability to infect and sicken humans. The CDC is taking a cautious approach to all of of these recently arrived HPAI viruses, however,  and has issued guidance for the testing, and prophylactic treatment of those exposed.

Update on Avian Influenza Findings

Last Modified: Apr 6, 2015

Print

Since December 2014, the United States Department of Agriculture has confirmed several cases of highly pathogenic avian influenza (HPAI) H5 in the Pacific, Central, and Mississippi flyways (or migratory bird paths). The disease has been found in wild birds, as well as in a few backyard and commercial poultry flocks. The Centers for Disease Control and Prevention (CDC) considers the risk to people from these HPAI H5 infections to be low. No human cases of these HPAI H5 viruses have been detected in the United States, Canada, or internationally.

Poultry Findings Confirmed by USDA’s National Veterinary Services Laboratories Include:

Captive Wild Bird Findings Confirmed by USDA’s National Veterinary Services Laboratories:

Wild Bird Findings confirmed by USDA’s National Veterinary Services Laboratories are available here.

Surveillance for avian influenza is ongoing in commercial poultry operations, live bird markets, and in migratory wild bird populations.

USDA is coordinating closely with its partners, including Arkansas, California, Idaho, Kansas, Minnesota, Missouri, Nevada, Oregon, Utah and Washington State officials, the U.S. Department of the Interior and the U.S. Department of Health and Human Services, on avian influenza surveillance, reporting, and control efforts.  The United States has the strongest AI surveillance program in the world, where we actively look for the disease and provide 100% compensation to affected producers to encourage reporting.

USDA continues to inform OIE and international trading partners of these findings.  USDA is working with trading partners to minimize trade impacts on poultry and poultry products as much as possible.

All bird owners, whether commercial producers or backyard enthusiasts, need to continue practicing good biosecurity, preventing contact between their birds and wild birds, and reporting sick birds or unusual bird deaths to State/Federal officials, either through your state veterinarian or through USDA’s toll-free number at 1-866-536-7593.  Additional information on biosecurity for backyard flocks can be found at healthybirds.aphis.usda.gov

USDA emphasizes that poultry, poultry products and wild birds (see biosecurity and wild birds) are safe to eat if they are properly handled and cooked to a temperature of 165 degrees Fahrenheit.

We continue to see a remarkably rapid spread of HPAI H5N2 across the country, and while it has not yet been shown to present a human health hazard, it is increasingly impacting the poultry industry.

Stay tuned.

APHIS: H5N2 Confirmed In South Dakota, 4th Farm Hit In Minnesota

 

# 9895

 

We’ve two announcements today from the USDA’s  APHIS (Animal and Plant Health Inspection Service) regarding HPAI avian flu in the United States.  

 

First,  South Dakota has become the 13th state to report H5N2 – this time in a turkey farm in Beadle County.    Given the rapid spread across the Western states so far, we should not be surprised to see more states added to this list.

Second, Minnesota reports their 4th commercial turkey farm – this time in Nobles County – hit with the highly pathogenic H5n2 virus.  Of note, Nobles county is in the extreme south of the state, and not adjacent to any of the previous counties reporting outbreaks.

What follows are excerpts from the two APHIS press releases, after which I’ll be back with a bit more.

CDC considers the risk to people from these HPAI H5 infections in wild birds, backyard flocks and commercial poultry, to be low

WASHINGTON, April 2, 2015 -- The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of highly pathogenic H5N2 avian influenza (HPAI) in a commercial turkey flock in Beadle County, South Dakota.  The flock of 53,000 turkeys is located within the Central flyway, where this strain of avian influenza has previously been identified and is highly similar to the other H5 HPAI viruses detected this year. CDC considers the risk to people from these HPAI H5 infections in wild birds, backyard flocks and commercial poultry, to be low.  No human infections with the virus have been detected at this time.

Samples from the turkey flock, which experienced increased mortality, were tested at the South Dakota State University Animal Disease Research & Diagnostic Laboratory.  The APHIS National Veterinary Services Laboratories in Ames, Iowa confirmed the findings. APHIS is working closely with the South Dakota Animal Industry Board on a joint incident response. State officials quarantined the affected premises and birds on the property will be depopulated to prevent the spread of the disease. Birds from the flock will not enter the food system.

WASHINGTON, April 2, 2015 -- The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of highly pathogenic H5N2 avian influenza (HPAI) in a commercial turkey flock in Nobles County, Minnesota.  This is the fourth confirmation in a commercial flock in Minnesota.  The flock of 21,000 turkeys is located within the Mississippi flyway where this strain of avian influenza has previously been identified. CDC considers the risk to people from these HPAI H5 infections in wild birds, backyard flocks and commercial poultry, to be low.  No human infections with the virus have been detected at this time.

Samples from the turkey flock, which experienced increased mortality, were tested at the University of Minnesota Veterinary Diagnostic Laboratory and the APHIS National Veterinary Services Laboratories in Ames, Iowa confirmed the findings.

While primarily a concern for the poultry industry, a week ago, in  CDC: HPAI H5 Viruses In The United States,  we looked at the CDC’s advice regarding these avian viruses.

 

For reasons that are not yet clear, this year we’ve seen the greatest geographic expansion of highly pathogenic avian flu viruses in almost a decade, with countries from Africa, to Europe, to Asia, and North America seeing either the return of H5N1, or the introduction of one (or more) of several new HPAI reassortant viruses. .

For now – in North America, anyway – the biggest concerns lie with poultry producers.  Unlike in Europe, Asia, and the Middle East - the clades spreading in the United States have not been shown to be pathogenic in humans. 

 

But as the recent emergence of H5N8, H5N2, and H5N6 have proven – influenza viruses are always changing -  and what we can say about their behavior today cannot be guaranteed for the future.

APHIS: USDA Confirms 2nd H5N2 Outbreak In Minnesota Turkey Flock

# 9876

 

Three weeks after we first learned from APHIS: HPAI H5N2 In A Minnesota Turkey Farm in Pope County, we are informed that a second farm has been affected in Lac Qui Parle County.  

 

Given that these counties are not immediately adjacent, and a  CIDRAP News report (see Wild birds nixed as Minnesota H5N2 source) from earlier this week quoted the Minnesota Department of Natural Resources (DNR) saying they found no evidence of the H5N2 strain in samples from wild birds in the area, it will be very interesting to see if there are any epidemiological links between the two poultry operations.

 

Here is the statement, posted on the APHIS website, this afternoon.

 

 

USDA Confirms Highly Pathogenic H5N2 Avian Influenza in Commercial Turkey Flock in Minnesota

CDC considers the risk to people from these HPAI H5 infections in wild birds, backyard flocks and commercial poultry, to be low

WASHINGTON, March 27, 2015 -- The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of highly pathogenic H5N2 avian influenza (HPAI) in a commercial turkey flock in Lac Qui Parle County, Minnesota.  This is the second confirmation in a commercial flock in Minnesota.  The flock of 66,000 turkeys is located within the Mississippi flyway where this strain of avian influenza was previously identified. CDC considers the risk to people from these HPAI H5 infections in wild birds, backyard flocks and commercial poultry, to be low.  No human infections with the virus have been detected at this time.

Samples from the turkey flock, which experienced increased mortality, were tested at the University of Minnesota Veterinary Diagnostic Laboratory and the APHIS National Veterinary Services Laboratories in Ames, Iowa confirmed the findings. APHIS is working closely with the Minnesota Board of Animal Health on a joint incident response. State officials quarantined the affected premises and birds on the property will be depopulated to prevent the spread of the disease. Birds from the flock will not enter the food system.

The Minnesota Department of Health is working directly with poultry workers at the affected facility to ensure that they are taking the proper precautions. As a reminder, the proper handling and cooking of poultry and eggs to an internal temperature of 165 ˚F kills bacteria and viruses.

As part of existing avian influenza response plans, Federal and State partners are working jointly on additional surveillance and testing in the nearby area. The United States has the strongest AI surveillance program in the world, and USDA is working with its partners to actively look for the disease in commercial poultry operations, live bird markets and in migratory wild bird populations.

USDA will be informing the World Organization for Animal Health (OIE) as well as international trading partners of this finding. USDA also continues to communicate with trading partners to encourage adherence to OIE standards and minimize trade impacts. OIE trade guidelines call on countries to base trade restrictions on sound science and, whenever possible, limit restrictions to those animals and animal products within a defined region that pose a risk of spreading disease of concern.

These virus strains can travel in wild birds without them appearing sick. People should avoid contact with sick/dead poultry or wildlife. If contact occurs, wash your hands with soap and water and change clothing before having any contact with healthy domestic poultry and birds.

All bird owners, whether commercial producers or backyard enthusiasts, should continue to practice good biosecurity, prevent contact between their birds and wild birds, and report sick birds or unusual bird deaths to State/Federal officials, either through their state veterinarian or through USDA’s toll-free number at 1-866-536-7593.  Additional information on biosecurity for backyard flocks can be found at http://healthybirds.aphis.usda.gov.

CDC considers the risk to people from these HPAI H5 infections in wild birds, backyard flocks and commercial poultry, to be low

WASHINGTON, March 26, 2015 -- The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of highly pathogenic H5N2 avian influenza (HPAI) in a wild Canada goose in Laramie County, Wyoming.  This is the first finding of the Eurasian lineage avian influenza viruses in wild birds in the Central flyway. CDC considers the risk to people from these HPAI H5 infections in wild birds, backyard flocks and commercial poultry, to be low.  No human infections with the virus have been detected at this time.

The sample, taken from a sick bird, was tested by the Wyoming State Veterinary Laboratory and confirmed by USDA’s National Veterinary Services Laboratories in Ames, Iowa.  The United States has the strongest AI surveillance program in the world, and USDA is working with its partners to actively look for the disease in commercial poultry operations, live bird markets and in migratory wild bird populations.

Two days ago, in  CDC: HPAI H5 Viruses In The United States,  we looked at the CDC’s advice regarding these avian viruses.

 

While the USDA offers the following biosecurity advice for those who may come in contact with wild birds:

Bird Enthusiasts:

Do not pick up deceased or obviously sick birds. Contact your State, tribal, or Federal natural resources agency if you find sick or dead birds.

• Wear rubber gloves when cleaning your bird feeders.
• Wash hands with soap and water immediately after cleaning feeders.
• Do not eat, drink, or smoke while cleaning bird feeders.

Hunters:

Follow routine precautions when handling wild birds.

• Do not handle or consume game animals that are obviously sick or found dead.
• Do not eat, drink, or smoke while cleaning game.
• Wear rubber gloves when cleaning game.
• Wash hands with soap and water, or alcohol wipes, immediately after handling game.
• Wash tools and working surfaces with soap and water and then disinfect.
• Keep uncooked game in a separate container, away from cooked or ready-to-eat foods.
• Cook game meat thoroughly; poultry should reach an internal temperature of 165 degree Fahrenheit to kill disease organisms and parasites.
• To report unusual signs in birds you have seen in the wild, call 1-866-4-USDA-WS. To learn more about how you can help, visit usda.gov/birdflu.
