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.

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
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.

Avian Influenza Found in Wild Bird in Butte County, California

January 5, 2015: A confirmed positive Avian Influenza (AI) serotype H5N8 was found in a wild Gadwall in Butte County, California. The pathogenicity of the AI strain is still being confirmed, but the National Veterinary Services Laboratories (NVSL) report it is consistent with Highly Pathogenic Avian Influenza (HPAI). The bird was collected as a part of enhanced surveillance by USDA Wildlife Services and is not a surprise due to given migratory patterns. This particular strain is not considered a public health threat and has not been found in commercial poultry.
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 District Office or USDA.
