Avian flu found in Foster Farms turkey flock near Waterford
Strain is harmless to humans, officials say

A strain of avian flu harmless to humans has been found at a Foster Farms turkey facility near Waterford. The company’s website says the firm’s early-detection program caught the outbreak in a single, rural turkey ranch, which has been quarantined and the birds to be humanely killed.

Federal agriculture officials said the strain detected is H5N8, which is not known to harm humans. The similarly named bird flu strain H5N1 ravaged poultry across Asia in 2003 and is more easily spread among humans. Testing occurred after the flock experienced a spike in deaths.

“The good news is it isn’t a human issue, but it is an industry issue because it can wipe out the flock fairly quickly,” said Bill Mattos, president of the Modesto-based California Poultry Federation. Mattos estimated the area-wide toll from an outbreak could affect up to 200,000 birds.

“We’ve been watching for this since those cases in British Columbia, Canada, a few weeks back,” Mattos said. As wild birds migrate along the Pacific Flyway, they bring the deadly disease with them, spreading it where they land or where droppings fall. He urged those with small backyard blocks to keep their birds in coops this winter. Infected birds will die quickly, he said.

In mid-December, the U.S. Department of Agriculture reported finding the same strain in guinea fowl and chickens from a 100-bird backyard poultry flock in Winston, Ore. Foster Farms said it reported the outbreak to the USDA. It may be the first U.S. commercial outbreak.

The Foster Farms statement says: “According to USDA policy, the ranch was quarantined and will be humanely depopulated by the USDA and Animal and Plant Health Inspection Service (APHIS) to prevent introduction to migratory and commercial flocks. No poultry products in the marketplace are impacted.”

According to the website, Foster Farms increased bio-security measures at all its West Coast facilities as soon as the other incidents were seen, working with agricultural and veterinary leaders on prevention measures.

“To further protect the health of its poultry and ensure the safety of its products, Foster Farms has long employed strict and industry-leading biosecurity practices including isolation of poultry farms, traffic control and sanitation. The company has maintained a continuous testing program for avian influenza since 2000. Foster Farms is committed to providing premium quality poultry products that are healthy, delicious and safe,” the statement concludes.

“This company has a very sophisticated process in place to handle this,” Mattos said. “It’s one ranch. It’s been locked down with just the one employee there. We’re just trying to keep it encapsulated.”

The outbreak may cause further export problems, however. China stopped importing American poultry products as soon as the outbreak surfaced. Mattos said Stanislaus County farms export only about 1 percent of their poultry, but nationwide some 30 percent of the flocks are sent abroad.

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.

California turkey farm quarantined after bird flu detected
BY THEOPOLIS WATERS
CHICAGO Mon Jan 26, 2015 11:42am EST

Jan 26 (Reuters) - A California turkey farm has been quarantined after confirmation of the first case of an outbreak of the highly pathogenic H5N8 avian influenza strain in the Pacific Northwest and in a commercial flock, the U.S. government said.

The news on Saturday came just weeks after China banned U.S. poultry after an outbreak of another strain of bird flu in the Pacific Northwest.

In the latest outbreak, Foster Farms said in a statement that it had informed the U.S. Department of Agriculture after detecting the H5N8 strain on a single turkey ranch in Stanislaus County following routine testing.

State and government labs confirmed the findings from samples submitted by Foster Farms, which had experienced a spike in bird deaths, according to the USDA.

The USDA's policy requires that the ranch be quarantined. The agency will humanely kill or destroy the birds to prevent the spread of the disease to migratory and commercial flocks.

In 2013, California produced 13 million turkeys, according to the latest USDA data.

The agency said H5N8 did not pose a health risk to the public, and birds from the involved flock would not enter the food system.

A few weeks ago, China had banned all imports of U.S. poultry, poultry products and eggs because of recent reports of highly pathogenic strains of avian influenza.

The ban came after Hong Kong in late December suspended imports of certain U.S. poultry and poultry products after two separate virus strains, including H5N2 in northern pintail ducks, were identified in Whatcom County, Washington, according to the USDA.

Until now, neither virus has been found in U.S. commercial poultry, and no human cases with these viruses have been detected in the United States, Canada or internationally.

The discovery of bird flu on a commercial farm will undoubtedly cause more trade disruptions for the United States, said Rabobank analyst Don Close.

"That is scary," he said during a panel discussion at a commodity conference in Miami. (Additional reporting by Tom Polansek in Miami)

US: HPAI confirmed in Californian turkey flock

This is the first finding of HPAI in commercial poultry during the ongoing disease incident in the Pacific Flyway.

Samples from the flock, which experienced increased mortality, were tested at the California Animal Health & Food Safety Laboratory System (CAHFS) and the APHIS National Veterinary Services Laboratories in Ames, Iowa confirmed the finding. APHIS is partnering closely with the California Department of Food and Agriculture (CDFA), which has quarantined the facility. APHIS and CDFA have initiated an incident command response, and APHIS will assist CDFA in depopulating the remaining birds on the property to prevent the spread of the disease.

Federal and State partners are working jointly on additional surveillance and testing in the nearby area, following existing avian influenza response plans. These plans also will include preventing the movement of risky animals or products out of the immediate area to prevent further disease spread. 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.

The USDA notified the World Organization for Animal Health (OIE) on 25th January of this detection as part of USDA's ongoing reporting of all HPAI findings.

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, Europe and Africa that has caused some human illness. Detailed analysis of the virus is underway in cooperation with the US Centers for Disease Control and Prevention.

Bird flu found in commercial flock

Quarantine lifted in Benton, Franklin counties in Wash.


By DON JENKINS

Capital Press

Highly pathogenic bird flu has struck a commercial turkey flock in California’s Central Valley, escalating the virus’ threat to the U.S. poultry industry.

The U.S. Department of Agriculture posted a notice Jan. 24 reporting that H5N8 bird flu had been confirmed in Stanislaus County.

Foster Farms, which has several poultry farms in the county, said it detected the virus during routine testing and alerted the USDA’s Animal and Plant Health Inspection Service.

The virus was confirmed in one turkey house with 9,000 birds and is related to avian influenza strains previously found in migrating ducks in Washington, Oregon, Idaho, California and Utah, according to a report by the World Organization for Animal Health.

Although tests were negative for avian flu in other turkey houses on the farm, the other birds will be euthanized, according to the USDA.

The USDA and California Department of Food and Agriculture have quarantined the farm.

Bird flu spread to 11 British Columbia, Canada, commercial poultry farms in the first half of December, but until this

this instance the highly contagious and lethal virus had been confined in the U.S. to non-commercial flocks, wild birds and captive falcons.

“We feared that at some point it was going to end up in commercial operations,” USA Poultry and Egg Export Council President Jim Sumner said.

Backyard flocks with access to the outdoors and in contact with disease-carrying wild birds have been infected in Washington, Oregon and Idaho.

Low pathogenic bird flu — less virulent than the highly pathogenic strains circulating in the West this winter — was detected in a Stanislaus County, Calif., quail farm last April.

The European Union and Japan on Monday reacted to the newest case by banning poultry raised, processed or shipped from California. Many countries have already banned poultry from Washington, Oregon and Idaho and likely will now put California on the list.

None of the West Coast states are major poultry producers for export, but their ports provide access to Asian markets.

Poultry exporters already were struggling with port slowdowns that have affected other commodities. Restrictions on shipping from the West Coast will further hamper the industry, Sumner said.

The Port of Oakland is particularly important for poultry exports, he said.

“The thing that concerns us is California is a transit center for the world,” Sumner said. “You can’t feasibly airfreight poultry.”

The Washington State Department of Agriculture on Tuesday lifted a quarantine imposed in parts of Benton and Franklin counties after two non-commercial flocks were infected with highly pathogenic bird flu.

The quarantine, which was in place for 21 days, restricted the movement of eggs, poultry or poultry products in the zone.

The avian influenza detected in the two Benton County backyard flocks in December apparently did not spread beyond those two sites, according to WSDA.

Veterinarians with the U.S. Department of Agriculture and WSDA visited approximately 1,800 premises in the quarantine area and tested samples from birds at more than 70 locations. All samples tested negative for avian influenza.

Restrictions remain in place in parts of Clallam County, were a second quarantine was established after a flock was confirmed infected with the H5N2 avian influenza virus on Jan. 16.
