INTRODUCTION
Meat indispensable for sound human healthProvides several essential nutrients:
ProteinsAmino acidsMineral elements Vitamins
Meat subject to spoilage by:Chemical reactions Biochemical reactions Biological agents, including bacteria
Responsible for food-borne diseases
INTRODUCTION
Hence meat be produced so as to:Minimize chemical and biochemical changesPrevent chances of bacterial contamination and
growth Preserve quality
Slaughtering of lawful animals and birds essential to prepare for food purposes
Pre-slaughter management and bleeding methods regulated by:religious practices and legislations04/21/23 5

ESSENTIALS OF HALAL SLAUGHTERING
Islamic method of slaughtering - based on two important principles:Tasmiya - invoking name of Allah - slaughter being
done with His permissionTazkiyah - means purification
This in accordance with several commands given in the Holy Quran
04/21/23 7
ESSENTIALS OF HALAL SLAUGHTERING
“Forbidden to you (for food) are: dead meat, blood, the flesh of swine, and that on which hath been invoked the name of other than God; that which hath been killed by strangling, or by a violent blow, or by a head long fall, or by being gored to death; that which hath been partly eaten by a wild animal, unless ye are able to slaughter it (in due form) ….…. (Al Maida - V:4)
The Holy Prophet (pbuh) gave comprehensive guidelines on slaughtering of animals in following Hadith:
“Verily Allah, has prescribed proficiency in all things. Thus, if you kill, kill well; and if you slaughter, slaughter well. Let each one of you sharpen his blade and let him spare suffering to the animal he slaughters”.

ESSENTIALS OF HALAL SLAUGHTERING
Process of slaughtering in Islam - consolidated Slaughterer:
must be adult Muslim or one who believes in Holy Scriptures should be in possession of his mental faculties
Lay animal (except camel) on its left flank, preferably facing Kibla
Recite name of Allah:Subhan Allah, or La illaha illila ho, or Allah-o-Akbar or Bismillah Allah-o-Akbar
04/21/23 9
ESSENTIALS OF HALAL SLAUGHTERING
Lay animal (except camel) on its left flank, preferably facing Kibla
Recite name of Allah:Subhan Allah, or La illaha illila ho, or Allah-o-Akbar or Bismillah Allah-o-Akbar
Give quick incision using very sharp knife on front of the neck to severe: Wind pipe, Oesophagus, Carotid arteries, Jugular veins
Prohibited - practice of cutting off part of an animal or removing its skin while still alive
04/21/23 10
PRE-SLAUGHTER HANDLING OF ANIMALS - 1. Selection of animals
Islam permits consumption of few animals and birds only
Strictly prohibited:PorkBlood Carrion Dead animalsAll carnivorous animals All birds of prey
04/21/23 11
1. Selection of animals
Permitted animals:All herbivorous, even-toed ruminants
Animal for Halal slaughter be:Healthy Free from any apparent or
hidden impurities/diseaseMust be legally owned
The Holy Prophet (pbuh) advised companions to use very sharp knife
Further instructed that sharpening of knife not be performed in front of slaying animal
04/21/23 12
3. Rest prior to slaughtering
Islam promotes calm and rested animals prior to slaughtering: Not fatigued Not excited Not nervous
Prohibited - any act that causes neurosis or excitement or other abnormal behavioural changes in animal
Prohibited in Islam - Practice of collective slaughtering - other animals do not view their companion being killed Research reveals - practices inhumane
04/21/23 13
3. Rest prior to slaughtering – Scientific evidenceModern methods require animal prior to slaughtering
not be subjected to:StressFatigueNeurotic Otherwise excited
Rough handling of animals in pre-slaughter period adversely affects meat qualityResult - dark, firm and dry meat (dark cutting meat)
Fatigued or starved animals Organisms from gut may invade blood stream and
eventually muscles
04/21/23 14
3. Rest prior to slaughtering – Scientific evidence
Proper relaxation before slaughtering:Helps animal to bleed wellBuilds up muscle glycogen essential to lower pH of
meatIncreases storage life by reducing chances of
microbial growthImproves taste due to conditioning/ tendernessHelps delay or reduce fermentation in stomach
may otherwise give meat characteristic smell known as ‘bone taint’
04/21/23 15
4. Stress prior to slaughtering- Scientifc evidence
Generally regarded undesirable that animal awaiting slaughter view slaughtering process – causes stress
Animals under stress - lead to undue emotional instability and fatigue
Anorexia, etc. Discharge hormones from adrenal glands:adrenaline from adrenal medulla17 hydroxy- and 11-deoxy-corticosterones from
adrenal cortexHormones deplete muscle glycogen and potassiumDeleterious effects on meat quality To prevent these adverse effects, tranquilizers
recommended to calm stocks in transit.
04/21/23 16
5. Feeding the animals
Holy Prophet Muhammad (pbuh) advised that animals destined for slaughtering be:well fed provided with drinking water
Preferable that animals have free access to feed and water prior to slaughtering
Two schools of thoughts:Animal to remain hungry - FastingAnimal be well fed
Fasting animals - Fasting animals before slaughter recommended in modern abattoirs
04/21/23 17
5. Feeding the animals – Scientific evidence
Fasting animals - Advantages claimed: Bleed better Carcass easier to dress Carcass has brighter appearance Reduced bulk of animal’s stomach Reduced chances of bacterial contamination from
gutFasted animals - Disadvantages:
Loss in weight of carcass and liverLower glycogen reserves in muscles Reduced gustative quality of meat
04/21/23 18
5. Feeding the animals – Scientific evidence
Well-fed animals:Glycogen level in muscle reaches higher levelEnsures production of adequate lactic acid Lowers pH of meatSuch meat has good: Appearance, Taste,
Tenderness, Longer shelf-lifeMeat spoilage bacteria prefer growth at high pH levels
- around pH 7.0Any decrease from normal value of about 6.8 reduces
chances of bacterial multiplication, especially food poisoning ones
04/21/23 19
5. Feeding the animals – Scientific evidence
Meat of soothed and well-fed animals:pH attains 5.5 or even lower level
Meat of fatigued or neurotic animals:pH varies from 6.5 to 7.0
To produce meat of good keeping and eating quality, often recommended to feed animals prior to slaughtering
In some cases sugar solution fed to quickly restore glycogen level in tissues

6. SLAUGHTERING PROCEDURE - Halal
Slaughtering rules apply to animals and birds in complete physical control of man - all domesticated birds and animals (except camel)
Conventionally, slaughtering process consists of two to three different stages
Depends on religious practices and legislationsPosture of animal and bleeding method governed by religious
and national legislationsWestern countries require animals be stunned before
slaughteringStunning widely practiced in Western abattoirs Main objective
make animal unconscious for gentle and painless death No standard method for all animals under all conditions Muslims and Jews not in favour of stunning
6. SLAUGHTERING PROCEDURE Modern method - 1. Stunning
Stunning effective in having calm animal Stunning may adversely affect quality of carcass
cause injury to medulla oblongata in brain - controls blood circulation and respiration
Desirable these systems continue to function - help pump blood out of carcass when blood vessels cutMethod of shooting by free bullet - too dangerous to use in abattoirs
Captive bolt - discardedCarbon dioxide anesthesia - exact dose of gas
important for specific length of time04/21/23 21
04/21/23 22
6. SLAUGHTERING PROCEDURE – Modern method -1. StunningElectrical stunning widely used
increases frequency of ‘blood splash” - appearance of small dark red areas in meat
also lowers glycogen reserves of muscleapproximately in 5 % electrically stunned animals
heart failure - animal dead before incision madeStunning - outcome of industrial revolutionInitially meant to protect the slaughterer and other
employeesReality - no relation with mercy on animalsMore animals be slaughtered in least time
04/21/23 23
SLAUGHTERING PROCEDURE 2. Animal positioningIslamic method - lay animal on left flank preferably
facing Kibla
Scientific evidence When laid on left flank, likelihood of more blood to
drain owing to body pressure on heartLaying animal enables it to convulse results from contraction of muscles due to lack of
oxygen in brain cells when incision made in neckDuring convulsions blood squeezed out of vesselsHence more blood drains out
a pre-requisite for meat of superior eating and keeping quality
04/21/23 24
SLAUGHTERING PROCEDURE 2. Animal positioning -Scientific evidenceDuring convulsions blood squeezed out of vesselsHence more blood drains out
a pre-requisite for meat of superior eating and keeping quality
Evidence suggests more blood lost from sheep in horizontal position than those hung vertically
Islam permits use of knife or any sharp object for bleeding
Incision made in neck with simultaneous recitation of the name of Allah - Takbir
Takbir has religious significance to believermakes submission to Allah
04/21/23 25
SLAUGHTERING PROCEDURE 3. Bleeding techniques
Slaughtering actually done in the name of Allah“So eat of (meats) on which God’s name has been
pronounced if ye have faith in His Signs” (Al Anaam - Vl:118).
Slaughtering not in name of any person or deity in accordance with following commands:
“Eat not of meats on which God’s name has not been pronounced: that would be impiety. But the evil ones ever inspire their friends to commit end with you if ye were to obey them, ye would indeed be Pagans”
(Vl:121).
04/21/23 26
SLAUGHTERING PROCEDURE 3. Bleeding techniques - Islamic method
Cut throat transversely without injuring spinal cord to severe carotid arteries, jugular veins, oesophagus and trachea
Two requirements in slaughter of animals for meat: animals be dispatched without unnecessary
sufferingbleeding be as complete as possibleWhen both carotid arteries and veins severed
connection between brain and body retained via spinal cord and brain sends messages to heart and lungs
Heart pumps blood to parts of body drained out from severed blood vessels in neck
04/21/23 27
SLAUGHTERING PROCEDURE 3. Bleeding techniques – Scientific evidence
Results of a comparison of study on different methods of slaughtering:
Maximum blood lost in Kosher method Jewish method similar to Islamic as regards
physical details Minimum when chicken simply beheadedIslamic method ensures maximum blood drainage
from body before completion of death processUnconsciousness induced between 3 to 6 seconds
04/21/23 28
SLAUGHTERING PROCEDURE 3. Bleeding – Scientific evidence
Blood excellent medium for growth of microorganismsMeat retaining more blood than critical level liable to bacterial
spoilageBlood retention in tissues can cause unpleasant appearance
and discolouration in meatKeeping and eating qualities of meat depend, in part, on
removal of maximum blood from carcassTo produce good carcass animal be bled effectivelyHeart and respiratory system must function continuously as
long as possible after severance of blood vesselsThis attained most thoroughly when heart and respiratory
functions retained by maintaining medulla oblongata/spinal cord
04/21/23 29
SLAUGHTERING PROCEDURE 3. Bleeding techniques – Scientific evidence
Positioning of animal in Islamic method: clearly prevents retraction of carotids ensures rapid onset of unconsciousness and
painless deathIn Islamic method of slaughtering maximum
blood drained - outranks other slaughtering techniques
HENCE BETTER QUALITY OF MEAT

ANIMAL RIGTHTS IN ISLAM
Islam recognized animal rights long before human rights recognized in Western World
Numerous Ahadiths on kindness and mercy towards animals
Holy Prophet (pbuh) advised: Nourish animals well Save animals from hunger and thirst Show kindness to animals Do not hit or mark animal on its face Do not shoot arrows at cattle or bird tied or held up Do not fight animals for sports or recreation Do not unjustly kill even a sparrow or smaller bird
(other than for food)
04/21/23 31
EXTRODUCTION
Current scientific data reveals Islamic recommendations for slaughtering animals highly rational
Good physique and health considered basic requirement for selection of food animals
Pre-slaughter management of animals requires they should not be fatigued, excited or neurotic
Proper rest, absence of hunger and thirst and use of sharp knife alleviate pains of death
