Stunning

Stunning is the process of rendering animals immobile or unconscious, without killing the animal, prior to their being slaughtered for food.

History

A primitive form of stunning was used in premodern times in the case of cattle, which were poleaxed prior to being bled out. However, prior to humane slaughter pistols and electric stunners, pigs, sheep and other animals (including cattle) were simply struck while fully conscious.

The belief that this was unnecessarily cruel and painful to the animal being slaughtered eventually led to the compulsory adoption of stunning methods in many countries. One of the first campaigners on the matter was the eminent physician, Benjamin Ward Richardson, who spent many years of his later working life developing more humane methods of slaughter. As early as 1853, he designed a lethal chamber that would gas animals to death relatively painlessly, and he founded the Model Abattoir Society in 1882 to investigate and campaign for humane methods of slaughter. He even experimented with the use of electric current at the Royal Polytechnic Institution.
