USA: LPAI in a duck breeder flock

24 April, 2019

As part of routine surveillance for H5/H7 Avian Influenza, H5 low pathogenic avian influenza (LPAI) was detected in a commercial duck breeder flock (9,500 birds) in Monterey , Monterey County - California. Partial HA sequencing determined the H5 to be a LPAI virus of North American wild bird lineage. Further characterization is pending virus recovery. There have been no clinical signs of illness or increased mortality on the premises. 
The USDA Animal Plant Health Inspection Service (APHIS) and the California Department of Food and Agriculture (CDFA) are conducting a comprehensive epidemiological investigation and have implemented enhanced surveillance and testing related to this finding. Two additional commercial poultry premises associated with the initial premises have been quarantined and sampled for avian influenza virus. Results are pending.
