In March 2022, there was an outbreak of “highly pathogenic avian influenza” (HPAI) at Rembrandt Foods, one of the world's largest in-line egg producing facilities. The farm, owned by billionaire Glen Taylor, decided to kill all of its 5.3 million birds through a horrific mass killing method known as "ventilation shutdown plus" (VSD+), whereby ventilation openings in the industrial sheds full of birds are closed, and some combination of heat, steam and/or carbon dioxide gas are introduced, eventually killing the animals via suffocation. VSD+ has been widely criticized as inhumane by animal welfare organizations
