Important Message to Bird Owners in Los Angeles, Riverside, San Bernardino and Ventura counties

If you own backyard birds, it is imperative that you restrict movement of your flock. Do not bring in any new birds or move out any existing birds. It is essential that good biosecurity measures are set in place for those who own backyard birds. These include simple steps like:

1) Washing hands and scrubbing boots BEFORE and AFTER entering poultry areas

2) Cleaning and disinfecting tires and equipment before moving them off the property

3) Instituting a 30-day isolation/quarantine of birds in your flock in which you have noticed symptoms, AND PLEASE CALL THE STATE BIRD HOTLINE, 866-922-2473.
