UK government proposes ban on CO2 stunning for pigs in abattoirs

The UK government has launched a consultation to phase out the use of high-concentration carbon dioxide (CO2) for stunning and slaughtering pigs in abattoirs. The proposal seeks to replace CO2 with more humane alternatives, such as argon gas or automated electrical stunning, which officials state are proven to reduce animal suffering.

Currently, CO2 is used to stun approximately 90% of pigs in UK abattoirs. The move follows recommendations from the Animal Welfare Committee (AWC), which described the continued use of CO2 as ethically unacceptable due to the pain, respiratory distress, and fear it causes animals. The AWC has recommended a five-year phase-out period.

Farming Minister Stephen Morgan stated that the transition aims to meet public expectations for high animal welfare standards and reduce the industry's reliance on CO2 supplies, which are subject to volatility caused by international conflicts, such as those in the Middle East. The consultation, which runs until December 21, will gather views on the costs, feasibility, and necessary timescales for businesses to adapt to these changes.
