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.
