H5N8 strikes backyard flock in Oregon, commercial farm in California
Highly pathogenic H5N8 avian influenza has struck another backyard flock in Oregon and another commercial farm in California, continuing the outbreaks in those states and elsewhere that have resulted from incursion of the highly pathogenic virus into migratory birds in the Pacific Flyway that began last year.

The Oregon flock, comprising about 90 domestic birds including chickens, ducks, and turkeys, is near Tumalo, in Deschutes County. The property they inhabit adjoins ponds where migratory birds congregate, according to a Feb 14 Oregon Department of Agriculture (ODA) news release.

The property has been secured and a quarantine zone set up. Backyard bird owners are being encouraged by the ODA to try to prevent their birds from contact with wild birds, to monitor their birds closely, and to report any sick or dead birds.

In addition, the Oregon Department of Fish and Wildlife has asked people to report any observance of dead wild birds. The agencies state that the outbreaks pose no threat to public health.

Meanwhile, the World Organization for Animal Health (OIE) has posted notification of another outbreak of H5N8 on a commercial chicken and duck farm in Kings County, California, in the same general region where a similar outbreak occurred in January.

The number of susceptible birds on the farm is listed as 114,000. No specific number of cases or deaths is given "because of missing information," but the flock experienced an increase in chicken mortality and the situation is being monitored, the report said.

The OIE notice says the US Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) and California agencies are continuing a "comprehensive epidemiological investigation and enhanced surveillance (including wild bird surveillance of hunter harvested birds)."

Introduction of H5N8 into the Pacific Flyway in 2014 has resulted in new combinations, with avian flu viruses of European and North American origin, including H5N2, explains the notice.

WASHINGTON – The US Department of Agriculture confirmed an outbreak of highly pathogenic H5N8 at a commercial poultry farm in Kings County California. At least 114,000 birds are susceptible to the virus. USDA reported its findings to the World Animal Health Organization (OIE).

The outbreak hit the commercial chicken and duck farm on Feb. 2, according to the USDA's report to the OIE. The Animal and Plant Health Inspection Service (APHIS) of the USDA and launched an epidemiological investigation at the unidentified poultry farm. APHIS confirmed H5N8 virus in the flock on Feb. 12, and animal health officials quarantined the farm. APHIS reported that the detection of H5N8 at the farm is related to recent avian influenza outbreaks in wild birds.

This is the second outbreak of highly pathogenic avian influenza to strike a commercial poultry farm in California. Foster Farms discovered the presence of H5N8 avian influenza at the ranch of one of its turkey suppliers in rural Stanislaus County, Calif.

In response to the finding Hong Kong announced a ban of poultry meat and products, including eggs, produced in Kings County. The Centre for Food Safety (CFS) said about 267,000 tonnes of chilled and frozen poultry meat and about 530 million poultry eggs were imported into Hong Kong from the US in 2014.

"The CFS has contacted the American authorities over the issue and will closely monitor information issued by the OIE on avian influenza outbreaks in the country, a CFS spokesman said in a statement. Appropriate action will be taken in response to the development of the situation."

In late January, the Canadian Food Inspection Agency implemented restrictions on live birds, eggs, raw poultry products and pet foods from California, Idaho, Oregon and Washington States. News reports state China and South Korea also implemented bans on US poultry in response to previous avian influenza outbreaks in the US.
