Method for processing poultry

A method for processing poultry, includes supplying live poultry, stunning the live poultry in a stunning device, placing the stunned poultry into product carriers advanced along a conveyor, killing the poultry and removing the feathers from the dead poultry in a plucking device. Downstream of the plucking device, the poultry is exposed to an electrical stimulation, an electrical voltage being applied across the carcass of the poultry. A method for controlling process parameters, especially the time and duration of execution of working steps in a process of mechanized working of slaughtered poultry, includes evaluating the tenderness of a specified meat portion prior to a due processing step and, after this evaluation, setting the important process parameters for the particular processing step to an optimal value.
