Also what needs to be understood is that there is no pressure from the side of the government of the United Kingdom forcing Muslims to adopt such inhumane methods of slaughter. Therefore because of all the negative aspects of stunning, the Halal Monitoring Committee has set a blanket ruling disallowing stunning in any form.
“Stunning the animal before slaughter leaves a huge doubt into the halalness of the animal as many could be killed by the stunning especially in the case of poultry. Furthermore, it prevents the drainage of entire blood resulting in it being retained in the animal and retained blood causes germs and bacteria, it deprives animals from the benefits of tasmiyah due to it being unconscious, it is inhumane to animals and causes unnecessary pain and suffering, it is in reality done not for animal rights purposes, but in order for the industry to kill more animals quicker so as to increase profits. According to the majority of the Ulama stunning is not accepted in Islam and stunning could render the meat Haram in many cases.” (Abu Ibrahim)
