Suffering of gassed pigs laid bare in undercover footage from UK abattoir

Hidden camera at slaughterhouse appears to show ‘utterly inhumane’ use of CO₂ to stun pigs before slaughter

New undercover footage showing British pigs being gassed prior to slaughter has led to renewed calls to investigate the use of CO₂.

Campaigners say the pictures – the first of their kind to be obtained in a UK abattoir – show the “utterly inhumane” nature of using CO₂ to stun pigs before being killed. But the pork industry says its use is recognised as the most welfare-friendly method available, and says alternatives are being sought.
