Secularists are campaigning for an end to non-stun slaughter, or at least for its strict limitation and reliable consumer information. Here are several papers and analyses from member organisations of the European Secularist Network.
Belgium: the Centre d’action laïque recalls the primacy of civil law over religious precepts.
France: the derogation is largely outdated, consumer information is non-existent. More information and analyses by the Ligue de l’Enseignement can be found here.
United Kingdom: The National Secular Society calls to end religious non-stun slaughter.
