Pre-slaughter stunning is required before killing in UK and EU abattoirs but exemptions exist for religious slaughter, creating ongoing welfare and ethical debate.
Pre-stun slaughter using effective methods renders animals insensible before blood loss and death. Non-stun slaughter requires consciousness through the period of blood loss, which welfare science indicates causes pain and distress in the seconds to minutes before unconsciousness. Promoting reversible stunning methods acceptable to religious authorities offers a welfare improvement pathway without compromising religious practice.
