The most common stunning method for pigs in the United States and Europe, particularly in larger plants, is electrical high-voltage stunning. The head-to-body version, causing cardiac arrest and reduction in poststunning movement, is preferred.

The incidence of these problems has been reduced by careful control of stun current and electrode position and by keeping the stun-to-stick time of the animal to a minimum.
