During the course of our investigation, GourmetCruelty.com discovered corpses of ducks who had literally burst open through overfeeding. Investigators also found many birds who had choked to death on their own vomit. Necropsies performed by veterinarians on dead ducks taken from Hudson Valley Foie Gras determined that some of the birds had died of aspiration pneumonia—a painful and often fatal condition caused when, during the process of forced-feeding, food is pushed into the lungs of the birds.
