Various carcass cleaning apparatuses and methods are described and illustrated, wherein carcasses can be cleaned by at least partially immersing carcasses within reservoirs moved by a conveyor. The reservoirs can be filled with cleaning fluid, receive carcasses to immerse the carcasses in the fluid, and can then be drained of such fluid, wherein the drained fluid can be collected, filtered, and supplied again to reservoirs for immersing and cleaning additional carcasses.
