Recently, the muslim world enjoyed the celebration of Eid al-adha, in which every muslim should sacrifice a sheep (or camel, ox...) but the slaughter of these animals has to be done in a one prescribed method.

Islamic Halal slaughter of sheep has increasingly come under attack from animal rights activists telling tales of barbaric blood-thirsty ritual slaughter.

It is true that when the blood flows from the throat of an animal it looks violent, but just because meat is now bought neatly and hygienically packaged on supermarket shelves does not mean the animal didn’t have to die? Non-Islamic slaughter methods dictate that the animal should be rendered unconscious before slaughter. This is usually achieved by stunning or electrocution. Is it less painful to shoot a bolt into a sheep’s brain or to ring a chicken’s neck than to slit its throat? To watch the procedure does not objectively tell us what the animal feels.

The scientific facts

A team at the university of Hannover in Germany examined these claims through the use of EEG and ECG records during slaughter. Several electrodes were surgically implanted at various points of the skull of all the animals used in the experiment and they were then allowed to recover for several weeks. Some of the animals were subsequently slaughtered the halal Islamic way by making a swift, deep incision with a sharp knife on the neck, cutting the jugular veins and carotid arteries of both sides together with the trachea and esophagus but leaving the spinal cord intact. The remainder were stunned before slaughter using a captive bolt pistol method as is customary in Western slaughterhouses. The EEG and ECG recordings allowed to monitor the condition of the brain and heart throughout.

The Halal Islamic method

With the halal method of slaughter, there was not change in the EEG graph for the first three seconds after the incision was made, indicating that the animal did not feel any pain from the cut itself. This is not surprising. Often, if we cut ourselves with a sharp implement, we do not notice until some time later. The following three seconds were characterised by a condition of deep sleep-like unconciousness brought about by the draining of large quantities of blood from the body. Thereafter the EEG recorded a zero reading, indicating no pain at all, yet at that time the heart was still beating and the body convulsing vigorously as a reflex reaction of the spinal cord. It is this phase which is most unpleasant to onlookers who are falsely convinced that the animal suffers whilst its brain does actually no longer record any sensual messages.

The Western method

Using the Western method, the animals were apparently unconscious after stunning, and this method of dispatch would appear to be much more peaceful for the onlooker. However, the EEG readings indicated severe pain immediately after stunning. Whereas in the first example, the animal seizes to feel pain due to the brain starvation of blood and oxygen – a brain death, to put it in laymen’s terms – the second example first causes a stoppage of the heart whilst the animal still feels pain. However, there are no unsightly convulsions, which not only means that there is more blood retention in the meat, but also that this method lends itself much more conveniently to the efficiency demands of modern mass slaughter procedures. It is so much easier to dispatch an animal on the conveyor belt, if it does not move. Also, the blood left in the body contains uric acid which should be purified by the kidneys, but once dead, nothing is working and the meat is no more clean, even after boiling.


so appearances can deceive !

Not all is what it seems, then. Those who want to outlaw Islamic slaughter, arguing for a humane method of killing animals for food, are actually more concerned about the feelings of people than those of the animals on whose behalf they appear to speak. The stunning method makes mass butchery easier and looks more palatable for the consumer who can deceive himself that the animal did not feel any pain when he goes to buy his cleanly wrapped parcel of meat from the supermarket. Islamic slaughter, on the other hand, does not try to deny that meat consumption means that animals have to die, but is designed to ensure that their loss of life is achieved with a minimum amount of pain.

The holistic view

Islam is a balanced way of life. For Muslims, the privilege of supplementing their diet with animal protein implies a duty to animal welfare, both during the rearing of the animal and during the slaughter. Modern Western farming and slaughter, on the other hand, aims at the mass consumer market and treats the animal as a commodity. Just as battery hens are easier for large-scale egg production, Western slaughter methods are easier for the meat industry, but they do neither the animal nor the end consumer any favours. The Islamic way guarantees a healthier life for the animal and a healthier meat for the consumer.

This prescribed Halal method of slaughtering animals is being applied since Muhammad (SAAS) life, means before more than 14 centuries.
