Abstract: A veterinarian infectious waste containment system having an animal cage and a flushing system slidable thereinto, and a process for containing infectious waste. The flushing system has a stainless steel waste collection pan and a means for flushing mounted at the top of the waste collection pan. The flushing system has an inlet which is fluidly connected to a water supply and the waste collection pan has an outlet fluidly connected to a drain. The means for flushing comprises disassemblable piping sections having apertures for delivery of fluid by spray jets. The water supply can have disinfectant selectively added to it; after the animal waste has been removed from the waste collection pan, the waste collection pan itself can be selectively flushed with the water with disinfectant. A stainless steel shroud extends a portion of the way from the flusing system towards the top of the cage and fits against the stainless steel side walls of the cage.
