The United States Department of Agriculture has confirmed several findings of highly pathogenic avian influenza (HPAI) in the Pacific flyway since mid-December. The first commercial poultry detection [JRH1] was in a turkey flock in California on January 23. USDA considers this finding to be part of the ongoing avian influenza disease incident. Commercial poultry producers follow strict biosecurity practices and raise their birds in very controlled environments. There is no immediate public health concern as a result of these detections.

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

Wild Bird Findings confirmed by USDA’s National Veterinary Services Laboratories are available http://www.aphis.usda.gov/wildlife_damage/downloads/WILD%20BIRD%20POSITIVE%20HIGHLY%20PATHOGENIC%20AVIAN%20INFLUENZA%20CASES%20IN%20THE%20UNITED%20STATES.pdf.

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 Washington, Oregon and California, Nevada, Utah, and Idaho 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 report these findings to the World Animal Health Organization (OIE) as part of the ongoing Pacific Flyway avian influenza incident. 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.

Background Information

The H5N8 virus originated in Asia and spread rapidly along wild bird migratory pathways during 2014, including the Pacific flyway. In the Pacific flyway, the H5N8 virus has mixed with North American avian influenza viruses, creating new mixed-origin viruses. This is not unexpected. These mixed-origin viruses contain the Asian-origin H5 part of the virus, which is highly pathogenic to poultry. The N parts of these viruses came from North American low pathogenic avian influenza viruses.

USDA has identified two mixed-origin viruses in the Pacific Flyway: the H5N2 virus and new H5N1 virus. The new H5N1 virus is not the same virus as the H5N1 virus found in Asia that has caused some human illness. The new H5N1 virus is not expected to be a human-health risk, but rather to have the same or a lower risk than H5N8. Detailed analysis of the virus is underway in cooperation with CDC.

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 the 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 12 February 2015, the USDA APHIS National Veterinary Services Laboratories (NVSL) confirmed HPAI EA H5N8 virus in a commercial chicken and duck flock in Kings County, California. The flock was experiencing an increase in chicken mortality. The detection of the HPAI H5N8 in the commercial chicken and duck flock is related to the recent avian influenza events in wild birds. The partial HA/NA sequence is >99% similar to A/gyrfalcon/WA/41088-6/2014 HPAI EA H5N8 based upon direct sequence attempt from chicken swab specimen. The premises has been quarantined. Comprehensive epidemiological investigation and enhanced surveillance on the affected premises and in the area is being conducted.

Bird flu strikes second California poultry farm

A commercial chicken farm in central California has been stricken with highly pathogenic bird flu.

A second California commercial poultry farm has been stricken with highly pathogenic bird flu. It’s the farthest south the virus has surfaced yet.

The U.S. Department of Agriculture confirmed the Eurasian H5N8 virus in a 114,000-bird chicken farm in Kings County in the San Joaquin Valley. The agency added the farm Friday to a list of bird flu outbreaks in U.S. commercial and non-commercial flocks since mid-December.

No further information, including the name of the farm, was available Monday from the USDA.

The USDA reported to the World Organization for Animal Health that the outbreak began Feb. 2 with an increased mortality among chickens.

The virus was confirmed Feb. 12, and the premises were quarantined. The flock included ducks, according to a report posted by the Organization for Animal Health.

Canadian authorities reacted Friday by banning poultry raised, processed or shipped from California. Hong Kong banned poultry from Kings County. China and South Korea have enacted bans on U.S. poultry in response to previous cases.

Bird flu has infected wild birds, non-commercial flocks and a game bird farm in Washington, Oregon, Idaho, Utah, California and Nevada since mid-December.

The only previous commercial poultry flock infected in the U.S. was a 145,000-turkey Foster Farms operation in Stanislaus County. The virus was confirmed there Jan. 23.

Stanislaus County’s county seat, Modesto, is 126 miles north of Hanford, the county seat of Kings County.

Highly pathogenic Eurasian bird flu was first confirmed in North America Dec. 1 at a British Columbia, Canada, commercial poultry farm. The virus spread to 10 other B.C. commercial chicken and turkey operations by Dec. 17.

The virus appeared in the United States in a northern pintail duck found dead at Wiser Lake in Whatcom County in northwest Washington. Another disease killed the migrating duck.

Migratory waterfowl carry the virus, but are immune to its ill effects. The virus is lethal to poultry and a variety of native birds.

The USDA recently added a great horned owl and bald eagle to the list of wild birds infected by avian flu. Both birds were in Canyon County, Idaho.

Avian influenza in a second California poultry farm

16 February, 2015
A commercial chicken farm in central California has been found positive to the highly pathogenic avian influenza virus. On 12 February 2015, the USDA APHIS National Veterinary Services Laboratories (NVSL) confirmed HPAI EA H5N8 virus in a commercial chicken and duck flock in Kings County, California. The flock was experiencing an increase in chicken mortality. The detection of the HPAI H5N8 in the commercial chicken and duck flock is related to the recent avian influenza events in wild birds. The partial HA/NA sequence is >99% similar to A/gyrfalcon/WA/41088-6/2014 HPAI EA H5N8 based upon direct sequence attempt from chicken swab specimen.

AVIAN INFLUENZA UPDATES

Highly Pathogenic Avian Influenza in Commercial Poultry Flock (Broiler Chickens and Ducks) in Kings County, CA

Highly Pathogenic Avian Influenza (HPAI) was detected in a commercial poultry operation that consists of broiler chickens and ducks in Kings County, California. The flock experienced increased mortality, and samples were submitted to the California Animal Health and Food Safety Laboratory for testing. The samples were then sent to the United States Department of Agriculture's (USDA) National Veterinary Services Laboratory for confirmation. On February 12, 2015, the infection was confirmed as influenza A virus subtype H5N8. The strain is compatible with EA-H5N8.

There is no immediate public health concern with this Avian Influenza Virus strain or the others that have been found in the Pacific Flyway since December 2014. Poultry and eggs that are cooked properly are still safe to consume.

CDFA and USDA have initiated an emergency disease response. The infected premises and other commercial poultry farms in the control area have been placed under State Veterinarian Quarantine. State and federal veterinarians will oversee depopulation of the remaining birds on the property in order to prevent the spread of the disease. Within the control area, movement of poultry and poultry products is prohibited unless under an official permit. Other movement (e.g. vehicles and equipment) will be monitored and require appropriate biosecurity measures.

Surveillance and outreach efforts are in effect and will continue over the next several weeks. Increased biosecurity and keeping birds housed away from open water sources that attract wild waterfowl is advised during this time. If you observe signs of illness or increased mortality, please call your private veterinarian, Sick Bird Hotline at 866-922-2473, CDFA Animal Health Branch District Office, or USDA. For more information, please visit: USDA APHIS Avian Influenza Disease Website.

Avian influenza hits 2nd commercial poultry farm in California
California officials confirm presence of highly pathogenic avian influenza at broiler and duck operation in Kings County
Release Date: 2015-02-16
Highly pathogenic avian influenza (HPAI) was detected in a commercial poultry operation that consists of broiler chickens and ducks in Kings County, California, the California Department of Food and Agriculture (CDFA) reported. The agency has not yet released any information concerning any companies that may be affiliated with the operation, which is the second commercial poultry farm in California to have a confirmed outbreak of avian influenza.

The flock experienced increased mortality, and samples were submitted to the California Animal Health and Food Safety Laboratory for testing. The samples were then sent to the United States Department of Agriculture's (USDA) National Veterinary Services Laboratory for confirmation.

On February 12, the infection was confirmed as H5N8 avian influenza. According to a report on the World Organisation for Animal Health (OIE) website, 114,000 birds were susceptible to the virus.

The first case of HPAI in a California commercial poultry flock was confirmed on January 24, when an H5N8 avian influenza outbreak occurred at a Foster Farms turkey operation in Stanislaus County.

CDFA and USDA have initiated an emergency disease response in connection with the Kings County outbreak. The infected premises and other commercial poultry farms in the control area have been placed under a state veterinarian quarantine. State and federal veterinarians will oversee depopulation of the remaining birds on the property in order to prevent the spread of the disease. Within the control area, movement of poultry and poultry products is prohibited unless under an official permit. Other movement such as vehicles or equipment will be monitored and require appropriate biosecurity measures.

Surveillance and outreach efforts are in effect and will continue over the next several weeks. Increased biosecurity and keeping birds housed away from open water sources that attract wild waterfowl is advised during this time.
