Use of water-based foam to depopulate ducks and other species.
Current control strategies for avian influenza virus, exotic Newcastle disease, and other highly virulent poultry diseases often include surveillance, quarantine, depopulation, disposal, and disinfection. On-farm depopulation and disposal methods reduce potential movement of virus and improve biosecurity. Water-based foam depopulation was developed as a potential alternative mass emergency poultry depopulation procedure. The use of water-based foam is conditionally approved by the USDA Animal and Plant Health Inspection Service for use with floor-reared birds. This study reports on the use of water-based foam to depopulate other species including call ducks, chukars, Pekin ducks, and Japanese quail. Foam caused a rapid onset of airway occlusion. Although all species tested were depopulated with water-based foam, the time to cessation of activity varied by species, with quail being faster than chukars, broilers, and ducks.
