Sentinel Chickens

The sentinel chicken flocks serve as an early warning system for the detection of SLE, WEE, and WNV transmitted by mosquitoes within the district boundaries.  Blood samples are taken bi-weekly from the sentinel chickens and analyzed by the CDPH’s Viral and Rickettsial Disease Lab to determine the presence of virus antibodies, indicating whether mosquitoes in the area have transmitted a virus that could potentially infect people and animals. This early detection allows us the increase our control efforts and public outreach to prevent the human infections.  The AVMVCD utilizes 10 flocks throughout the district.
