H5N1 Avian Flu Spreads Among California Wild Birds, Puts California on AlertSource: Google Street View

California is facing a new outbreak of Avian Influenza, specifically the Eurasian strain H5N1, affecting wild birds this fall. The California Department of Fish and Wildlife (CDFW) confirmed the virus in two Canada geese, raising concerns as the feathery flu spreads to more counties.

The alarming situation echoes a similar scenario for bird enthusiasts and farmers, with waterfowl deaths reported in various locations, including Fresno, Glenn, Kern, and Yolo counties. This isn't an isolated issue, as 354 confirmed cases have been recorded from July 2022 to June 2023 across 44 California counties. Migratory patterns contribute to the virus resurfacing despite the apparent decline during warmer months.

The risk of humans contracting the flu from birds remains low, according to the Centers for Disease Control. However, experts advise residents and hunters to take precautions. Reporting sick or dead birds, keeping domestic poultry away from wild birds, and maintaining clean hunting gear are recommended preventive measures.

Hunters should be cautious when encountering waterfowl that appear unwell and ensure thorough cooking of game to 165 degrees Fahrenheit. Detailed safety guidelines are available on the CDFW website. Additionally, pet owners should clean their animals if they've been in contact with fowl.

If unsure about handling a downed bird, it's advised to contact a local wildlife rehabilitation center for assistance. The CDFW website provides helpful information and FAQs, including a flyer with more details. The USDA's website also offers a complete list of the latest HPAI H5N1 cases.
