This post forwarded from NPIP:
Well, it’s California’s turn now…. There is a confirmed AI positive wild bird found in Butte County. This is the notice from CDFA….
Confirmed positive (Korean H5N8, likely HP) wild Gadwall collected in Butte County.
This is a completely expected finding given migratory patterns. The bird was collected as a part of enhanced surveillance by USDA Wildlife Services. The CAHFS Lab has proactively developed a rapid test to differentiate the Korean strain from the No American strain. They obtained the preliminary positive yesterday and gave the alert to NVSL who rushed the confirmatory test. USDA confirmed Jan 1. Because this is an EXPECTED finding, no special notices are planned as of this AM. CDFA and local USDA staff will redouble their efforts to help backyard and other small producers tighten up biosecurity to the extent possible. We are also preparing for a rapid response to any incursion into domestic poultry in order to limit damage. Note that to date, this particular strain is NOT considered a public health threat.

Avian influenza news from the USDA: This week, as a result of increased surveillance in the Pacific flyway, USDA has confirmed the presence of HPAI in a wild duck in Butte County, California.
The samples in California were collected from a hunter-harvested gadwall in Butte County, California, as part of increased wild bird surveillance. Testing by the California Animal Health and Food Safety Laboratory, a National Animal Health Laboratory Network (NAHLN) laboratory, was positive on H5 PCR, and the sequencing results were consistent with Eurasian H5N8. The National Veterinary Services Laboratories (NVSL) received the samples on December 31 and confirmed the presence of HPAI H5N8. This is the same HPAI H5N8 strain that was found in Washington gryfalcons and the Oregon backyard poultry flock. This is not an unexpected finding, given wild waterfowl migratory patterns in the Pacific flyway.

The virus could come to Utah with migrating birds.

Utah’s wildlife and agriculture agencies are advising hunters and residents with backyard poultry flocks to be aware that two strains of highly pathogenic avian influenza virus (HPAI) have been detected in wild birds in California, Washington and Oregon.

While no affected birds have been reported in Utah, the state sits in a major migratory bird flight path, so it’s possible the disease could be transmitted to domestic birds as waterfowl migrate through Utah, Warren Hess, acting state veterinarian with the Utah Department of Agriculture and Food, said Tuesday in a news releases.

"This discovery underscores the importance of biosecurity for backyard bird owners," he said. "We strongly encourage owners to take biosecurity measures to reduce the risk of their flocks being exposed to wild birds. We also advise bird owners to monitor their flock closely and to report sick birds to the Department of Agriculture and Food."

Hess said there is no immediate public health concern. To date, the particular strains of avian influenza found in California, Washington and Oregon have not been implicated in human disease. The immediate concern is for domestic bird populations in Utah.

Utah’s commercial poultry industry has a robust avian influenza testing program. In addition, the Utah Division of Wildlife Resources routinely conducts mortality surveillance of wild bird populations. The HPAI virus has not been found in commercial poultry anywhere in the United States.

Backyard flock owners can report sick birds to the Utah State Veterinarian’s office at 1-801-538-4910 or by calling the USDA toll free at 1-866-536-7593.

Wild bird deaths can be reported to the DWR at 801-538-4758.

Wild duck with bird flu found in California

A wild duck in northern California has tested positive for highly pathogenic bird flu.


A wild duck in Butte County in northern California has tested positive for highly pathogenic avian influenza, adding to a string of unprecedented West Coast bird flu cases.

The U.S. Department of Agriculture on Wednesday confirmed that a hunter-shot duck in Butte County was infected with highly pathogenic H5N8. The USDA detected the virus Dec. 31, but didn’t make an announcement until Wednesday.

The wild duck was found as part of the USDA’s increased surveillance on the West Coast and increased outreach to backyard poultry enthusiasts, according to the USDA.

Highly pathogenic bird flu had never been detected in California, Oregon and Washington until the past month.

Low pathogenic bird flu was found last spring on a quail farm in Stanislaus County in central California. China still restricts all poultry and poultry products from birds slaughtered, processed and shipped from California.

Unlike British Columbia, Canada, where some 245,600 birds were culled at 11 poultry farms between Dec. 1-17, highly pathogenic bird flu has not been found in U.S. commercial poultry.

The virus in wild birds and backyard flocks in Washington and Oregon has still meant export restrictions for the U.S. poultry industry.

“It’s possible every additional finding prolongs the situation,” USA Poultry and Egg Export Council President Jim Sumner said Wednesday.

Some countries, such as South Korea and South Africa, have imposed bans on all U.S. poultry. The USDA says those bans are unwarranted.

Many countries have limited their bans to poultry and poultry products from Washington and Oregon.

Federal and state officials Tuesday euthanized approximately 500 birds in a backyard flock in Benton County in south-central Washington. The flock had been exposed to highly pathogenic H5N2 bird flu by domestic ducks moved from another flock 9 miles away.

The 140 ducks, chickens and turkeys in that flock were euthanized Monday, according to the Washington Department of Agriculture.

Also in Whatcom County, Wash., a wild duck and a captive gyrfalcon fed wild duck were infected with highly pathogenic bird flu in December.

Also that month, highly pathogenic bird flu broke out among a 100-bird flock of guinea fowl and chickens in Douglas County, Ore.

Officials suspect migratory waterfowl along the Pacific Flyway are carrying the disease. Highly pathogenic bird flu cases also have been reported in Asia and Europe within the past two months.

No human cases of the viruses have been reported, according to the USDA.

Related reports Immediate notification (16/12/2014)
Follow-up report No. 1 (19/12/2014)
Follow-up report No. 2 (29/12/2014)
Follow-up report No. 3 (07/01/2015)




Outbreaks There are no new outbreaks in this report


Epidemiology

Source of the outbreak(s) or origin of infection 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 in response to the HPAI H5N8 wild bird related event. As part of the increased AI surveillance of wild birds (performed by testing hunter harvested birds), an H5N8 with an amino acid sequence at the HA cleavage site that is consistent with highly pathogenic avian influenza has been identified in a wild gadwall duck in the Pacific flyway. HA and NA sequence fragments are essentially identical to that found in the reported gyrfalcon. Update on the Oregon backyard premises as of 2 January 2015: • A 10 km active surveillance zone has been initiated for avian influenza. - All backyard premises with birds in the 10 km surveillance zone will be monitored and tested for AI. - There are no commercial poultry premises within the 10 km surveillance zone. • Cleaning and Disinfection (C&D) of the backyard premises has been completed. The backyard premises will be under a monitoring program and release of the quarantine will not occur for at least 90 days following depopulation and is contingent on post C&D environmental testing. • A thorough epidemiological investigation was conducted in relation to the backyard infected premises. No traces into or out of the infected flock were found and it was determined that the AI H5N8 event was related to wild bird exposure. The HPAI H5N8 virus has NOT been found in commercial poultry anywhere in the United States.



Control measures

Measures applied Stamping out
Quarantine
Movement control inside the country
Disinfection of infected premises/establishment(s)
Vaccination prohibited
No treatment of affected animals

Measures to be applied No other measures





Future Reporting

The event is continuing. Weekly follow-up reports will be submitted.

Above report fails to state that the gadwall was from Butte County California and says the positive is not a new outbreak
