Supermarkets selling "halal" products also report that all animals are stunned before they are slaughtered. Tesco, for example, says "the only difference between the "halal" meat it sells and other meat is that it was blessed as it was killed." Concerns about animal suffering from slaughter without prior stunning has resulted in the ban of slaughter of unstunned animals in Denmark, Luxembourg, Belgium, The Netherlands, Norway, Sweden and Switzerland. Generally, killing animals in Islam is only permissible for two main reasons, to be eaten and to eliminate a danger, e.g. a rabid dog.
