Foam depopulation
Method of mass killing farm animals via foam / From Wikipedia, the free encyclopedia
Foam depopulation or foaming is a means of mass killing farm animals by spraying foam over a large area to obstruct breathing and ultimately cause suffocation.[1] It is usually used to attempt to stop disease spread.[2] Foaming has also been used to kill farm animals after backlogs in slaughtering occurred during the COVID-19 pandemic.[3] Foam depopulation has been used on poultry and pigs and has seen initial research for use on cattle.[4] It has faced criticism from some groups. Some veterinarians have called it inhumane,[5] along with many animal rights and animal welfare organizations who cite the pain caused by suffocation or the harm experienced by the stray survivors.[6][7]
