The report of two H5N2 outbreaks in turkey growers follws the report of H5N2 in a Minnesota turkey egg grower. The description of the Minnesota farm (In Starbuck in Pope County) matches a farm that was the subject of a report, with video of conditions in 2013. The farm managed 25,000 layers which can produce 100-130 eggs per season.

This high level may indicate this farm provides eggs to many turkey growers, which may include sites outside of Minnesota. The two farms in Missouri are near the two turkey processing plants in Missouri, Butterball in Carthage (near the Asbury grower) and Cargill in California (near the Fortuna grower).

Since the growers in Missouri are near processor sites for two different companies, the detection of H5N2 in both may signal a link back to the large egg producer in Minnesota.

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 Canada and the US. These findings are not unexpected as the EA-H5N8 virus continues to circulate. The EA-H5 clade 2.3.4.4 viruses are highly pathogenic for poultry. On 4 March 2015, the USDA APHIS National Veterinary Services Laboratories (NVSL) confirmed HPAI EA/AM H5N2 positive results from a commercial turkey breeder replacement flock in Pope County, Minnesota. Partial HA/NA sequence is >99% similar to A/northern pintail/Washington/40964/2014 based upon direct sequence attempt from turkey swab specimen. This is the first detection of HPAI EA/AM H5N2 in Minnesota and is outside the Pacific Flyway.

H5N2 strikes Missouri turkey farm
Filed Under: Avian Influenza (Bird Flu)

H5N2 avian influenza—which surfaced in the US Pacific Northwest in December and in Minnesota last week—has now struck at least one turkey farm in Missouri, according to reports yesterday.

The Missouri Department of Agriculture (MDA) reported that avian flu hit a turkey farm in Asbury, a town near the southwestern corner of the state, and that preliminary tests indicated avian flu at a facility at Fortuna, in central Missouri's Moniteau County.

A state official told the Associated Press (AP) that the virus on the Asbury farm was the same highly pathogenic H5N2 strain that has been confirmed in Washington, Oregon, Idaho, and Minnesota, said an AP story yesterday.

USDA sending team to assist
The MDA said in a statement that it was following "strict protocols to contain and eliminate the disease" and coordinating its response with the US Department of Agriculture (USDA) and state health officials. The USDA was sending an incident management team to Missouri.

The MDA did not disclose how many turkeys were sickened or how many are kept at the affected farm.

"The facilities were immediately quarantined and the remaining turkeys in the involved flocks will be depopulated and will not enter the food system," the agency said. "Following USDA protocols, surveillance and testing procedures are underway at properties near the affected facilities to ensure the virus has not spread."

Samples from Asbury were tested by a state veterinary lab and a USDA lab, the MDA said. It was awaiting confirmation of the preliminary positive result from Fortuna. Also, the state health department was monitoring workers exposed to the infected turkeys.

Update on Minnesota outbreak
Last week an H5N2 outbreak devastated a flock of 15,000 turkeys in west-central Minnesota's Pope County. On Mar 7 the Minnesota Board of Animal Health (MBAH) said the turkeys in the affected barn and in three others a half-mile away on the same farm had been euthanized and that the carcasses would be composted inside the barns. The turkeys in the other three barns tested negative for the virus, the board said.

Authorities set up a 10-kilometer quarantine zone around the affected farm. No other commercial turkey farms were situated in the area, but as of Mar 7 authorities had found 17 backyard flocks, which were tested and put under a 30-day quarantine, the MBAH said.

In an update yesterday, the MBAH said the control zone contained about 70 additional potential sites with poultry. It said officials were continuing to check for poultry at those locations and asking owners to closely monitor their birds.

The Minnesota outbreak is the first highly pathogenic H5N2 incursion in the Mississippi Flyway, USDA officials have said. The virus, which is spread by wild birds, has been found in several wild birds and backyard poultry flocks in Washington, Oregon, and Idaho in recent months.

H5N2 is considered to pose little risk to humans, since no human infections have ever been reported.

The Minnesota outbreak prompted 40 countries, including the European Union, to slap bans on Minnesota poultry imports, the Minneapolis Star Tribune reported on the evening of Mar 6. The story said China has banned all US poultry.
