The Butte County Department of Public Health (BCPH) has received notification from the California Department of Public Health (CDPH) of a bird flu (H5N1) infection in a non-commercial backyard poultry flock in Butte County. BCPH wants poultry owners to be aware of the potential for H5N1 exposure, know the signs of infected poultry, and take steps to prevent exposure to themselves and others. While the general public's health risk is low, people who work with birds, poultry, or cows or have recreational exposure to them are at higher risk. To date, there have been no reported human H5N1 bird flu cases among Butte County residents.
