Avian influenza H5N1 has resurfaced in susceptible wild birds in California, with preliminary detections made in late October and November from several counties. The last confirmed detection was in July 2024.
California’s location on the Pacific Flyway makes it a critical hub for migratory bird species, increasing the risk of disease transmission. Wild birds, particularly waterfowl and shorebirds, are the primary hosts of avian influenza viruses. Predators and scavengers can also be infected through contact with infected birds.
To reduce the spread of avian influenza, residents and hunters are advised to take precautions:
– Report dead wild birds to CDFW
– Prevent contact between domestic birds and wild birds
– Avoid feeding waterfowl at park ponds
– Wear protective equipment when handling game
Waterfowl hunters should also follow specific guidelines, including:
– Harvesting only healthy birds
– Handling game outdoors or in a well-ventilated area
– Wearing rubber gloves while handling game
– Thoroughly cooking all game to an internal temperature of 165 degrees Fahrenheit
The Centers for Disease Control considers the transmission risk of avian influenza to people low, but residents and hunters should take precautions to protect themselves.
