Death Foam

Depopulation foam is primarily used for mass culling during avian influenza and swine disease outbreaks, suffocating animals by blocking their airways with water-based or nitrogen-filled foam.

This method, approved by the American Veterinary Medical Association (AVMA), is widely used in poultry farms for rapid, humane euthanasia.

Research has also explored high-expansion nitrogen foam for swine depopulation, aiming to improve welfare and efficiency.
