Research into CO2 slaughter alternatives for pigs has intensified as the welfare science evidence grows. Understanding the state of alternatives helps advocates and producers evaluate options.
CO2 slaughter alternatives for pigs represent one of the clearest cases where the welfare science evidence, technological solutions and economic incentives are progressively aligning to drive change. The welfare problem - CO2 causes aversive gas burning before unconsciousness - is well-documented. The alternatives - inert gas systems - are proven and commercially available. The barrier is infrastructure cost and industry inertia. Retailer commitments to non-CO2 sourcing create market pull that accelerates transition. Consumer awareness of the issue and willingness to support brands committed to better slaughter practices is a meaningful lever for accelerating this shift.
