Abstract: A poultry stunning apparatus including a trough for containing water through which the poultry is carried for stunning. The apparatus also including an electrical control module configured to apply a DC current to the poultry at a voltage sufficient to stun the poultry and to apply AC current to the stunned poultry at a voltage and for a period of time sufficient to immobilize and relax the muscles of the stunned poultry, while at the same time avoiding or minimizing damage to the poultry tissue. The apparatus further including a stunning electrode positioned within the trough, the stunning electrode including a metal plate adapted and positioned within the trough to be contacted in a contact zone by the poultry as the poultry are carried along, the contact zone of the metal plate being substantially smooth and uninterrupted.

Abstract: A poultry stunning apparatus and method, the apparatus including an electrical control module configured to apply a DC current to the poultry at a voltage sufficient to stun the poultry and to apply AC current to the stunned poultry at a voltage and for a period of time sufficient to immobilize and relax the muscles of the stunned poultry, while at the same time avoiding or minimizing damage to the poultry tissue. In the method, DC voltage/current is applied for initial stunning, followed by an AC voltage/current to immobilize poultry and to further relax the muscles of the stunned poultry, such that the poultry does not exhibit involuntary motions, while at the same time avoiding or minimizing damage to the poultry tissue.
