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.
