Avian Influenza

2025-01-08: January Avian Science Notes, Vol 1

On January 8th, our State Veterinarian, Dr. Annette Jones, issued the following:

“Due to the continued spread of H5N1 Bird Flu in California, the State Veterinarian has implemented a ban on all California Poultry and Dairy Cattle Exhibitions at Fairs and Shows immediately until further notice. This action is required to minimize the danger of exposing people and non-infected cows and birds to the disease.”

Important message as Highly Pathogenic Avian Influenza (HPAI) continues to spread across our nation and state

There are no United States-approved HPAI tests,  for use with poultry, available to backyard poultry keepers.  Please do NOT buy such tests, nor think using a test made for cattle, is appropriate for your flock.

As always, if you have unexplained illness in your flock, contact:

Highly Pathogenic Avian Influenza (HPAI) continues to attack in California

2023-10-30: HPAI positive cases in Monterey & Merced counties

                 Oct. 30, 2023

Urgent:  After 2+ months of being free of Highly Pathogenic Avian Influenza (HPAI), California has a positive case.  The last case was a detection in wild birds in Monterey county.  The current case involves a commercial flock in Merced county.

While the HPAI risks from migrating waterfowl have long been known, more and more wild bird species are being infected with virus.   All poultry owners must increase their biosecurity efforts.

2022-10-25: More confirmed HPAI cases

       My thanks to United Egg Producers (UEP) for sharing the following.   Over the past 6 days, Animal and Plant Health Inspection Service (APHIS) has reported 26 confirmations of Highly Pathogenic Avian Influenza (HPAI).   Most of the confirmations were from backyard flocks.    The fall migration is continuing.    All bird owners should assume that the virus is present in wild birds.

2022-08-20: Positive HPAI cases and the counties impacted, continues to increase

      Thanks to our State Veterinarian, Dr. Jones, for keeping us informed.   Cases of Highly Pathogenic Avian Influenza (HPAI) unfortunately are on the increase.  They are no longer restricted to wild birds, backyard flocks have tested positive as well.  I will continue to tell my readers what I have been saying for decades:  protect your birds - keep them under a solid cover!
