WASHINGTON, April 21, 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 additional four flocks in Minnesota and South Dakota. No human infections with the virus have been detected at this time. CDC considers the risk to people from these HPAI H5 infections in wild birds, backyard flocks and commercial poultry, to be low.

USDA’s National Veterinary Services Laboratories confirmed HPAI H5N2 in the following counties and states:

Cottonwood County, Minnesota (April 20, 2015)
30,000 turkeys
2nd detection in this county

Wadena County, Minnesota (April 20, 2015)
301,000 turkeys

Kandiyohi County, Minnesota (April 20, 2015)
61,000 turkeys
8th detection in this county

Spink County, South Dakota (April 20, 2015)
33,300 turkeys

The affected premises have been quarantined 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 United States has the strongest AI surveillance program in the world. As part of the existing USDA avian influenza response plans, Federal and State partners as well as industry are responding quickly and decisively to these outbreaks by following these five basic steps: 1) Quarantine – restricting movement of poultry and poultry-moving equipment into and out of the control area; 2) Eradicate – humanely euthanizing the affected flock(s); 3) Monitor region – testing wild and domestic birds in a broad area around the quarantine area; 4) Disinfect – kills the virus in the affected flock locations; and 5) Test – confirming that the poultry farm is AI virus-free. USDA also is working with its partners to actively look and test for the disease in commercial poultry operations, live bird markets and in migratory wild bird populations.

For more information about the ongoing avian influenza disease incidents visit the APHIS website. More information about avian influenza can be found on the USDA avian influenza page. More information about avian influenza and public health is available on the CDC website.

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

Highly Pathogenic Avian Influenza

Our company has been collaborating with others in the poultry industry as well as government agencies and the University of Minnesota for months to monitor the avian influenza situation as it unfolds and to prepare for its possibility in our state.

Our experience to date is that the positives continue to be geographically isolated, and at this time, do not appear to be spreading from farm-to-farm.

The confirmed cases of HPAI below indicate the involved flocks owned or processed by Jennie-O Turkey Store as well as those being raised by contract and/or independent growers.

Wadena County, Minn., announced April 20 (Jennie-O Turkey Store facility)

Kandiyohi County, Minn., announced April 20 (Independent/contract grower)

Stearns County, Minn., announced April 16 (Jennie-O Turkey Store facility)

Otter Tail County, Minn., announced April 16 (Independent/contract breeder farm operation)

Kandiyohi County, Minn., announced April 16 (Independent/contract grower)

Barron County, Wis., announced April 16 (Jennie-O Turkey Store facility)

Meeker County, Minn., announced April 14 (One Jennie-O Turkey Store facility and one Jennie-O Turkey Store facility, managed by an independent grower)

Redwood County, Minn., announced April 14 (Independent/contract grower)

Stearns County, Minn., announced April 14 (Independent/contract grower)

Swift County, Minn., announced April 14 (Two Jennie-O Turkey Store facilities, managed by an independent grower)

LeSueur County, Minn., announced April 14 (Independent/contract grower)

Watonwan County, Minn., announced April 10 (Jennie-O Turkey Store facility)

Cottonwood County, Minn., announced April 10 (Independent/contract grower)

Lyon County, Minn., announced April 10 (Independent/contract grower)

Meeker County, Minn., announced April 8 (Jennie-O Turkey Store facility)

Kandiyohi County, Minn., announced April 7 (Independent/contract grower)

Stearns County, Minn., announced April 6 (Independent/contract grower)

Lac qui Parle County, Minn., announced March 27 (Independent/contract grower)
We test all of our flocks for influenza prior to processing. No birds diagnosed with HPAI are allowed to enter the food chain.

The flocks identified above are the only ones impacting Jennie-O Turkey Store at present. We continue to work with various stakeholders and experts to better understand the elements involved and to mitigate the impact of influenza on our animals and our production.

We fully support the epidemiologists working with state and federal officials to better understand how this disease is transferring from migratory birds to domestic poultry.

We continue to export product to our largest trading partner, Mexico, which established protocols last week that allow trade with specified restrictions.

Wadena County flock falls to flu, another Kandiyohi Co. flocked infected
By Tribune News on Apr 21, 2015 at 11:56 p.m.

WILLMAR — The highly pathogenic avian influenza was confirmed in central Minnesota for the first time Tuesday, while two other Minnesota counties reported additional flock detections Tuesday, according to the United States Department of Agriculture.

A commercial turkey flock of 310,000 was reported Tuesday in Wadena County. This is the first avian flu detection in the central Minnesota county.

An additional detection in a 61,000-bird commercial turkey flock was also reported in Kandiyohi County, the eighth location confirmed in the west central Minnesota county.

A second commercial turkey flock totaling 30,000 birds was also reported in Cottonwood County in southwest Minnesota.

All three flocks will be euthanized, according to the United States Department of Agriculture.

This latest loss brings the total of turkeys affected in Minnesota to 2,141,500 million since the first case was confirmed in March. The influenza has now been detected in 31 farms in 15 counties in Minnesota, according to the USDA.

As is the case for all confirmed cases, the infected farm is placed under quarantine. All commercial and backyard poultry operations within a 10-kilometer radius of the site are notified and placed in a control zone. Workers with the USDA and Minnesota Department of Agriculture will conduct surveillance testing of all flocks identified within the zone.

The Minnesota Department of Health reports that no human infections with this strain of the virus known as H5N2 have been detected.

However, in some cases certain highly pathogenic avian influenza H5 viruses can infect people and it is important to take precautions.

Is the wind to blame? Bird flu's spread remains mystery

By Andrew Broman editor@independentreview.net | Updated 3 hours ago

The most devastating avian flu outbreak to sweep through Central Minnesota in years has baffled scientists, farmers and poultry companies trying to figure out how exactly it’s getting into barns.

“Nobody I’ve talked to has a good handle on how (the virus) works,” said Dale Fenrich, who finances poultry farm sales and sells insurance policies to local turkey farmers. “It’s the hottest kill they’ve ever had in the system.”

The Department of Natural Resources plans to visit Meeker County as soon as this week to begin taking samples of waterfowl feces in an attempt to pinpoint the virus’ location. Officials believe the virus, known as H5N2, entered the region through migrating waterfowl, such as geese and ducks, but it’s a mystery why some barns are getting hit while others remain unscathed.

Meanwhile, the DNR is asking the public to stay alert and report any unusual bird die-offs. “If there’s a cluster of five or more birds, we definitely want to hear about that,” said Cory Netland, the region’s DNR wildlife manager. The DNR is also asking wild turkey hunters to allow the DNR to take swab samples of their birds’ trachea to test for the flu’s presence.

The virus is known to kill turkeys within 48 hours, and an estimated 2.1 million birds statewide have either died from infection or been euthanized as a precautionary measure. Health officials say the virus poses a low risk to humans.

Most of Meeker County’s turkey production takes place in Acton and Swede Grove townships, on the county’s western edge. With 14 farms in Meeker County, Jennie-O Turkey is by far the area’s largest producer, according to county feedlot records. Those 14 sites have permits to raise as many as 1,815,050 turkeys, while the next largest producer, Litchfield-based Langmo Farms, has four sites with a permitted maximum of 171,500 birds.

One of Jennie-O’s sites in Meeker County with a confirmed infection had 310,000 birds — the largest affected site in all of Minnesota, according to U.S. Department of Agriculture. The Minnesota Animal Health Board’s website lists the farm as having been euthanized.

The only farm site listed in feedlot records as having more than 300,000 birds is the Jennie-O Wilcox Lake Farm on State Highway 4, north of Grove City, though the Independent Review has not verified whether the Wilcox site has been affected by avian flu.

The next largest sites in Meeker County, listed as having more than 200,000 turkeys, include two Jennie-O farms in Action Township, known as the Buffalo Run and Galaxy Brood farms, according to feedlot records.

When infections occur, the USDA and the Animal Health Board issues alerts identifying flock sizes and counties in which infections are confirmed. But the agencies do not identify the farm’s owner or reveal the location, and state law treats turkey farm addresses and other data obtained by the Animal Health Board as private information.

Some farms volunteer more detailed information, and Jennie-O posts some information on its website. According to Jennie-O, two cases of avian flu in Meeker County occurred at barns owned by Jennie-O, with a third Meeker County case occurring at a farm owned by an independent contractor.

Throughout the state, Jennie-O has reported 18 confirmed cases at its farm sites. The total number of cases confirmed statewide is 31, including three new cases reported Tuesday.

When avian flu is detected at a farm, the farm is placed under quarantine, meaning turkeys cannot enter or leave the affected area. All turkeys at an affected farm are euthanized by covering the birds with a firefighting foam, which suffocates them. The birds are then composted and wood chips are added to help generate heat and accelerate the composting. Barns are then cleaned out and disinfected before any new turkeys can be introduced. The entire process takes about six weeks, after which the farm can return to production.

The USDA compensates farmers for birds which are euthanized, but not for birds killed by the virus itself. The compensation amount depends on the type of turkey and its fair market value.

The Independent Review contacted Jennie-O officials last week and submitted questions in an email to the company. A company official declined to answer questions, stating the company was in a “quiet period” related to its second quarter earnings report scheduled for May 20.

Hormel Foods, parent company of Jennie-O, announced Tuesday the avian flu would reduce turkey sales and “pressure earnings” during this year’s second half. “We are experiencing significant challenges in our turkey supply chain due to the recent HPAI (avian flu) outbreaks in Minnesota and Wisconsin,” stated Jeffrey M. Ettinger, chairman of the board, president and chief executive officer.

Virus hitchhiking on winds?
According to Fenrich, farmers and industry officials are frustrated particularly because the virus has infected flocks inside barns with stringent biosecurity measures. A leading theory among industry officials is that high wind speeds are helping to spread the virus, Fenrich said last week, essentially blowing contaminated particles into barns. “That’s what they’re all saying,” Fenrich said of his conversation with farmers and poultry executives.

Greg Langmo, owner of Langmo Farms in Litchfield, considers his operations as having high biosecurity standards, which include reducing traffic in the turkey barns, having employees change clothing and footwear between turkey barns, and even having employees shower between visits to different turkey barns.

“Turkey farmers are really clean people,” Langmo said during an interview earlier this month. “I’m probably showering four times a day. I wash my truck probably three or four times a week. You have to.”

Contacted on Tuesday, Langmo said he agreed high winds appear to be the primary culprit in spreading the disease. No scientific evidence confirms his suspicions, Langmo noted, but the randomness of virus’ spread — hitting some barns and farms while skipping others — points toward wind as the problem. “It’s just not reasonable that all these farms are having biosecurity breaches,” Langmo said.

Asked what steps could be taken to prevent wind from blowing into barns, Langmo said, “If I knew, I would be really rich.” A possible pathway for wind to enter a barn is through its ventilation system, which is needed to maintain a healthy environment for the turkeys. “If you turn the ventilation off, they’re all dead,” Langmo noted.

Langmo questioned whether euthanizing all turkeys at an affected farm is necessary given the apparent randomness of confirmed cases, and evidence indicating farms have succeeded in preventing the virus’ “horizontal” spread, meaning from barn to barn.

Langmo advocated for euthanizing birds only in barns that have tested positive for the virus. Euthanizing all birds at an affected farm puts a financial hardship on producers, Langmo added. While farmers are compensated for any birds euthanized that are not sick, producers face ongoing costs while their barns sit empty for weeks waiting to be restocked, he said.

A researcher at the University of Minnesota said H5N2 is unlike any previous avian flue strains introduced to North America. Describing the virus as “completely, completely weird,” Professor Carol Cardona said she’s not sure how the strain is spreading or what biosecurity measures can thwart it. “The public wants us to know more than we know,” she said. “All we can say is we don’t know. This is unprecedented.”

Researchers do know the virus is highly pathogenic. One milligram of infected feces contains the equivalent of 10 infectious doses, Cardona noted. “Does it get walked in? Does it get blown in? Does it get picked up by a small bird that goes through a hole in a screen?” she said, noting that multiple factors may be to blame for the virus’ spread.

She added, “We just don’t know what biosecruity (measures) are working to keep it out of most of our 600 turkey farms (in Minnesota).”

In working with the USDA and Animal Health Board to learn more about the virus’ spread, the DNR plans to collect samples within a 10-kilometer radius of affected farms, and those samples will be sent to a laboratory in Madison, Wis., to test for the virus’ presence. A total of 3,000 samples are expected to be taken statewide, according to Michelle Carstensen, DNR wildlife health program supervisor. As of Tuesday, 908 samples had tested negative for avian flu virus. Five tested positive, but further testing is needed to determine whether the strain is H5N2, she said.

Shifting into ‘catastrophe mode’
H5N2 is unlikely to disappear anytime soon, according a USDA veterinarian. Dr. John Clifford said last week the virus could stay in the region for years, causing the most problems during cool months. Heat kills off the virus, and producers are likely to find relief during summer months.

Poultry companies and government officials are quick to note that the virus has affected only a small percentage of turkeys both state- and nationwide, but uncertainty surrounding the virus’ transmission is creating stress for producers. Because so little is known about the virus, concerns and debates within the poultry industry are changing daily, Fenrich said. One poultry executive summed up the situation in telling Fenrich that the company’s employees “were in crisis mode last week and catastrophe mode this week.”

Routine practices, such as restocking farms with new turkeys, are now under scrutiny, Fenrich said.

Under normal circumstances, turkeys leave farms for market and are replaced with new, younger birds to be raised. But there is debate among officials whether it’s safe to introduce turkeys into any farm located within a 10-kilometer quarantined area, or “hot zone,” Fenrich said. “They’re worried about these birds getting sick again,” Fenrich said of discussions among industry and government officials.

Contact with wild species
Epidemiological comments The USDA Animal and Plant Health Inspection Service (APHIS), in conjunction with State Departments of Agriculture and Wildlife, are continuing to conduct a comprehensive epidemiological investigation and enhanced surveillance (including wild bird surveillance of hunter harvested birds) in response to the HPAI H5N8 and H5N2 wild bird related events. Novel avian influenza virus of Eurasian origin (EA-H5N8 clade 2.3.4.4) spread rapidly along wild bird migratory pathways during 2014. Introduction of this EA-H5N8 virus into the Pacific Flyway sometime during 2014 has allowed mixing with North American (AM) lineage viruses and generated new combinations with genes from both EA and AM origin (or “reassortant” viruses) such as this EA/AM H5N2-reassortant detected in the US. In addition, overlap of the Pacific, Central, and Mississippi Americas flyways has resulted in movement of the virus to the central part of the country. The EA-H5 clade 2.3.4.4 viruses are highly pathogenic for poultry.
