Bird Flu Returns to Sonoma County, Impacting Two Poultry Farms
Sonoma County, California is facing a renewed outbreak of highly pathogenic avian influenza (HPAI), with confirmed cases at a duck farm and an egg farm reported today.
Reichardt Duck Farm, located between Petaluma and Two Rock, detected a “modest increase in mortality” last week, leading to a positive HPAI confirmation on October 24th. Farm owner Phil Reichardt stated they began “depopulating” the flock on Sunday, euthanizing approximately 57,000 birds. Yesterday, the U.S. Department of Agriculture added a second case to its public database, at an undisclosed egg farm where 231,000 birds have died. This outbreak is particularly concerning as it arrives earlier in the season than previous years, potentially signaling a more widespread impact on poultry production.
Reichardt, whose farm was also affected in the 2023-24 season, expressed frustration with recurring challenges. “Look at the last six years now… It’s been hit after hit. We’re looking for our fate to change at some point,” he said. The industry has improved its response time, aiming for quicker depopulation to limit spread, but experts acknowledge the virus remains difficult to contain. According to the U.S. Department of Agriculture, HPAI typically spreads through migratory birds, particularly along the Pacific Flyway.
Officials are emphasizing biosecurity measures, noting that producers have become more adept at carcass disposal and preventative protocols since the significant losses experienced two years ago. Rodrigo Gallardo, a professor of poultry medicine at UC Davis, noted, “We’re all at high alert. We’re approaching winter. And we have learned a lot of things about biosecurity and prevention.” Affected farmers are eligible for indemnity programs, though Reichardt noted disagreements with the USDA regarding fair market value. The California Department of Food and Agriculture is working with the USDA to monitor the situation and prevent further outbreaks.
The Department of Agriculture will require a four-month waiting period before Reichardt Duck Farm can reintroduce birds, and officials will continue to monitor the situation closely throughout the winter months.
