When using this method business operators shall pay attention to avoid the fracture of the skull.
This method shall only be used for ruminants of less than 10 kg of live weight.

This method shall provide instantaneous maceration and immediate death of the animals. The apparatus shall contain rapidly rotating mechanically operated killing blades or expanded polystyrene projections. The capacity of the apparatus shall be sufficient to ensure that all animals are killed instantaneously, even if they are handled in a large number.

These methods shall not be used as routine methods but only where there are no other methods available for stunning.
These methods shall not be used in slaughterhouses except as a back-up method for stunning.
No person shall kill by manual cervical dislocation or percussive blow to the head more than seventy animals per day.
Manual cervical dislocation shall not be used on animals of more than three kg live weight.

6.2.
Shackles shall be wet before live birds are shackled and exposed to the current. Birds shall be hung by both legs.
