A Review of the Halal Poultry Slaughtering from Welfare and Legal Perspectives: Analysis of Research Results

Karrar Imad Abdulsahib Al-Shammari


The subject of halal slaughtering is one of the most widely discussed issues of animal cruelty and animal welfare in the public sphere. The discrepancy in understanding the contemporary and religious laws pertaining to animal slaughtering does not fully publicize to Islamic and Muslim majority countries especially with respect to interpreting the use of stunning in animals. The electrical stunning is the cheapest, easiest, safest, and most suitable method for slaughtering that is widespread and developed. However, stunning on head of poultry before being slaughtered is a controversial aspect among the Islamic sects due to regulations of the European Union and some other countries. The current review highlights the instructions of halal slaughtering, legal legislation, and the effect of this global practice on poultry welfare and the quality of produced meat.
