Avian influenza in Delaware

23 February, 2022

Avian influenza found in Delaware chicken flock (commercial egg type layers).
Testing has confirmed a case of avian influenza on a Delaware poultry farm that showed increased mortality over the past few days. Following an investigation by the Delaware Department of Agriculture, the U.S. Department of Agriculture’s National Veterinary Services Laboratory has confirmed poultry from this farm have tested positive for highly pathogenic H5N1 avian influenza (HPAI).
The farm is under quarantine to stop the spread of avian influenza to other flocks in the state. The birds on the affected farm (Egg-production complex), 1.2M  - will be depopulated.
Delaware becomes the 6th state to confirm HPAI H5 in commercial or backyard poultry since the virus began spreading in January (others are Maine, Indiana, Kentucky, New York, and Virginia). This finding is the first case of HPAI in commercial poultry in Delaware since 2004.
