Some Halal accreditors allow stunning, there was something in the Telegraph about it with the Nandos opening in Blackburn.
" Cllr Mulla, a former Blackburn with Darwen Mayor, phoned Nando’s head of customer engagement, David Manly to warn him the London-based Halal Food Authority accreditation used by the company’s suppliers was unacceptable to the LCM.
The HFA allows the stunning of chickens before slaughter, which Cllr Mulla and his organisation believe fails to meet the strict criteria of Islamic law.
The LCM insist on accreditation and inspection by the Leicester-based Halal Monitoring Committee which forbids it. "
