Religious slaughter methods that do not involve pre-stunning raise welfare concerns because animals may experience pain during throat-cutting while conscious, and welfare science is engaged with this sensitive area.
The welfare science of non-stunned slaughter is complex and sensitive. The scientific consensus - including from the Farm Animal Welfare Council and the BVA - holds that animals slaughtered without pre-stunning experience a period of pain and distress before loss of consciousness. The duration and severity of this period is debated, with studies showing consciousness may persist for 20 seconds to over two minutes after throat-cutting in cattle. However, this is a welfare question embedded in religious freedom debates where the science must be considered alongside legal and cultural rights. Many welfare advocates support dialogue with religious communities to identify stunning methods compatible with religious requirements rather than blanket prohibition.
