A poultry scalder, process and system of the immersion poultry scalding employs counterflow recirculation of scald liquid in a counterdirection to that of the travel of the poultry through the immersion tank. The tank liquid is counterflowed externally in stages from the bird exit station through one or more intermediate stations and to the bird entrance station, and the liquid removed from the tank is filtered, cleaned and sanitized with make-up water being added to the system being heated to scald temperature before it is returned to the immersion tank. Steam injection is introduced externally to the scalder via external pumping conduits employed for the staged counterflow.
