The conditions of the holding pens at all of the slaughter plants are extremely poor. Of particular note:
Agroindustrial Del Este Horse Slaughter Plant
Behind this dilapidated slaughter plant building were some empty pastures, overgrown with waist-high bushes. Behind one of these bushes, investigators found a dead horse in an advanced state of decay. Next to the decaying carcass was another horse skull. There were several more skulls visible throughout the area. None of them had any bullet holes, indicating that the horses had been left to die instead of being euthanized.
At this particular plant, horses are hosed down with a high pressure water jet, a procedure that greatly frightens the horses. As well, the worker often aims the water directly at their faces. In the chute that leads up to the entrance of the building, the horses are also moved with a high pressure water hose. Again, the water is aimed directly at the horses' faces, what makes them go back instead of moving forward. The floor of the chute is slippery from the water and from feces.
