Avian Influenza
Ongoing screening and surveillance for avian influenza has confirmed detection of a strain of Avian Influenza fatal to poultry at one turkey ranch in a remote area of central California.

This strain of avian influenza is confined exclusively to birds.

This is part of an ongoing AI incident in the Pacific Flyway where the disease has been detected in migratory wild birds.

All affected poultry are prohibited from entering the marketplace.

Poultry products purchased in the U.S. are safe for consumption.

There is no risk of contracting the avian flu virus from properly handled and cooked poultry.

Current status: (Saturday, January 24, 2015)

Upon detection of this AI strain on the ranch, USDA and California state officials immediately quarantined the facility to protect other flocks.

The turkeys will be humanely euthanized and disposed of under federal supervision of the USDA’s Animal and Plant Health Inspection Service (APHIS).

LIVINGSTON, Calif. (AP) — Hundreds of turkeys at a Central California ranch are being killed to prevent the spread of a type of avian flu that is not a threat to people but can decimate poultry flocks.
Foster Farms announced on Saturday that routine food safety screening uncovered the flu outbreak at the Stanislaus County ranch, which was quarantined in keeping with U.S. Department of Agriculture policies.
The Modesto Bee reports (http://bit.ly/1yZ6ujG) that federal agriculture officials identified the strain of bird flu virus as H5N8, which health experts says carries almost no health risk for humans.
The same strain infected a backyard flock of chickens and guinea fowl in Southern Oregon last month.
Another type of bird flu, H5N1, can infect humans although it is not easily spread.
Foster Farms says no turkey products have been affected by the outbreak.

The influenza virus was found at one of the company's facilities in Stanislaus County. In a statement, the company said no products on the market were affected by the outbreak, and the particular strain poses no risk to the public.

The facility was immediately quarantined by the California Department of Food and Agriculture. The U.S. Department of Agriculture will assist state officials in euthanizing the birds to prevent the disease from spreading, the federal agency said in a statement.

Tests at labs in Iowa and California confirmed the presence of the H5N8 virus, a strain that is not known to spread among humans. However, the strain is highly likely to cause disease among birds.

Avian flu has been detected at various sites in the U.S. and Canada since late 2014, but the outbreak at the Foster Farms ranch is the first time a commercial flock has become infected.


On Jan. 5, the USDA found a wild duck in Butte County with the same strain of avian flu as the outbreak at Foster Farms, according to state agriculture officials.

In Oregon, a backyard flock of geese, ducks and guinea fowl was euthanized in late December after the H5N8 virus was found there.

Update on Avian Influenza Findings in the Pacific Flyway
Last Modified: Jan 26, 2015 Print
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:

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 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

While HPAI viruses have not been found in commercial poultry, 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. The detection of the HPAI H5N8 in the commercial turkey flock is considered to be related to the recent avian influenza events in wild birds. The partial HA/NA sequences are >99% similar to A/gyrfalcon/WA/41088-6/2014 based upon direct sequencing from swabs of 2 different turkeys. The commercial turkey premises is in a remote location and has been quarantined. Comprehensive epidemiological investigation and enhanced surveillance is being conducted. Additional recent testing of other turkey houses on the premises has been negative for avian influenza.
