• Conventional definitions of quality are based on

the inherent or perceived physical characteristics

of meat.

• For most consumers they determine the meat’s

appeal, acceptability, utility and, ultimately, its

value.

Meat quality

Page 5: Future Prospects for Halal Meat Quality_2016

Conventional meat quality

• Consumers’ perception of meat quality is wide and subjective

• This perception reflects among others:

regional and national differences,

ethnicity and culture,

political and economic considerations,

individual beliefs and ideologies, and

package labelling information and context

Spiritual meat quality: Halal perspective

Page 8: Future Prospects for Halal Meat Quality_2016

• Spirituality and ideology influence people’s attitude towards

the killing of animals and the consumption of meat.

• Consideration of the source, life and death of the animal adds

another dimension to meat quality - one that cannot be

evaluated by science or measured by instruments.

• Thus, in addition to all the conventional terms used to convey

the qualities of meat, “spiritual quality” is of foundational

importance for faith groups.

Spiritual meat quality

Page 9: Future Prospects for Halal Meat Quality_2016

• Halal is a quality cue that is very difficult or impossible to

evaluate with the current methods.

• Therefore, trust is very important throughout the supply chain

for the acceptability of halal meat.

• Thus, sound traceability and involving those that Islam say can

be trusted in the supply chain are necessary for maintaining

the spiritual quality of halal meat .

Halal credence quality

Page 10: Future Prospects for Halal Meat Quality_2016

Industrial halal meat production

• Halal livestock

• Slaughtered alive in accordance with Islamic shariah

• Complete death before any further

workup/processing

• Humane and considerate treatment of livestock

(minimum stress and pain prior to and during

slaughter)

• Safety of the slaughterer and all concerned

Page 11: Future Prospects for Halal Meat Quality_2016

Critical points for the spiritual quality of halal meat

Page 12: Future Prospects for Halal Meat Quality_2016

Pre-slaughter stunning

Purpose of stunning

– To render the animal insensible to pain

– To minimise fear, panic and other adverse effects associated with slaughter

– Hygiene

– Worker safety

Page 13: Future Prospects for Halal Meat Quality_2016

Halal consumers divide on stunning

1) Those who totally reject stunning as non-Halal compliant

2) Those who accept stunning regardless of the method used

3) Those who accept stunning but are not sure which method is Halal compliant and want assurance in the following:

- Is the stunned animal alive before it was slaughtered?

- Is the stunning painful to the animal?

- Does it affect the wholesomeness of the meat?

Page 14: Future Prospects for Halal Meat Quality_2016

Head-only electrical stunning and associated processes

• The animal is restrained in the head bail that contains electrodes which contact the animals head behind the ears and the tip of the nose.

• The animal is stunned across the brain with an electric current of 1.5-2.5 A, 400V a.c. for 2-4 seconds.

• The animal is dropped onto a cradle or moving table and the Halal cut is performed as soon as practicable but usually within 10-15 seconds of stunning.

• Electro-immobilisation electrodes contact the animal between the nose and the anus and power is turned on (80-90 V d.c., 300mAmp,10 ms pulse at 15 pulses/sec).

• Electro-immobilisation is allowed to time out (15-30 seconds).

Stunning and electro-immobilization

Page 16: Future Prospects for Halal Meat Quality_2016

Potential halal pre-stunning methods

• Post-slaughter stun

• Reversible head-to-body electrical stunning

• Interferential current stunning

• Transcranial Magnetic stunning

• Microwave energy stunning

• Local or general anaesthesia with natural agents

• Modified atmosphere and Low Atmospheric Pressure stunning

Page 17: Future Prospects for Halal Meat Quality_2016

Recoverable head-to-body electrical stunning

• Using high frequencies (1-2A, 1000-2000 HZ, 350-500 V, 4 s) • Current NZ MIA study (AgResearch Ltd, Massey University, FIANZ, UPM,

Jarvis Engineering Ltd)

Page 18: Future Prospects for Halal Meat Quality_2016

Recoverable head-to-body stunning

• A current study comparing the use of high frequency

head-to-body and low frequency head-only electrical

stunning

• Bobby calves, cattle, sheep, goats will be minimally

anaesthetised, stunned using the two methods and

EEG recordings done

• Recovery following stunning and behavioural studies

carried out

Page 19: Future Prospects for Halal Meat Quality_2016

Interferential current stunning

De Domenico, G. (1982). The Australian Journal of Physiotherapy, 28(3), 14–18; Johnson and Tabasam (2003). Physical Therapy, 83(3), 208-223

• Used in acute and chronic pain management including

electro-narcosis and electro-anaesthesia

• Interferential Current is based on the summation of two

sinusoid alternating currents with their waveforms

slightly offset or out of phase

• This ‘mixing’ of the signals results in a low-frequency

current that consists of cyclical modulation of the

amplitude which is dependent on the difference of

frequencies of the two carrier signals

• When the signals are in phase, the carrier signals sum

to a value able to stimulate the tissue. When out of

phase, no stimulation results.

19.2mA current amplitude

Page 20: Future Prospects for Halal Meat Quality_2016

Transcranial magnetic stunning (TMS)

• Used in psychiatric therapy to induce seizures in patients

• Intense magnetic field is generated by passing a large

amount of current through a copper coil. The coil is

positioned close to the head so that the brain lies within

this magnetic field to affect a stun.

• Tried on 25 broilers with 20 successfully completed

• TMS at 35 or 50 Hz; 250-300 pulses; 80-51% power; 5 s

• EEG traces showed evidence of insensibility and a

dominance of theta and delta wave

• Unconsciousness lasted for 15 to 20 s

Microwave Energy Stunning (MES)

Small et al. (2013) Animal welfare 22, 291-296.

• MES has been used in euthanizing laboratory animals by raising the brain temperature by 8°C

• Four sheep were exposed to 4 kW of energy at 922 MHz for between 5 and 20 s. Temperature profiles, EEG and histology of the brain and onset of recovery following stunning were determined

• Application of microwave energy caused rapid increases in brain temperature within 10-20 s to 43°C (a point above which insensibility would be expected to occur)

• EEG showed high amplitude activity similar to the epileptiform activity induced by the current practice of electrical stunning

Patent International Application No. PCT/AU2011/000527

Page 22: Future Prospects for Halal Meat Quality_2016

Local or general anesthesia with natural agents

• Slaughter stress and pain can be reduced by local anaesthesia using the commercial anaesthetics

• Residue in meat would render such application commercially unviable

• A commercial food-grade fish anaesthetic with iso-eugenol as the active ingredient (AQUI-S™) has been approved for use in many countries

• This has been used to successfully anaesthetize fish including Atlantic cod and salmon

• The availability of natural anaesthetics for fish raises the prospects of others suitable for use in local anaesthesia of red meat animals prior to slaughter

Animal Welfare affects meat’s spiritual

quality

Science can tell us about an animal…

Physical

Mental

Environment

..but this doesn’t get us all the way…

Our beliefs and ethics also have an important role to play in deciding what is acceptable

“Meat from animal with high welfare is…..”

Page 27: Future Prospects for Halal Meat Quality_2016

Conclusion

• A substantial quantity of meat is produced around the world using industrial halal methods and associated processes.

• The conventionally-defined attributes of meat quality are demanded by halal and conventional consumers alike.

• additional attribute of “spiritual quality” is paramount for those who consume halal for religious reasons.

• Consumers are increasingly associating meat quality with animal welfare

Page 28: Future Prospects for Halal Meat Quality_2016

Conclusion cont….

• Head-only pre-slaughter stunning or no-stunning are commonly

used in halal meat production

• There are a number of technologies currently being trialled with

potential to reduce quality defects associated with stunning when

they become commercially available.

• Research to produce technologies and processes to harmonise

the religious and the temporal requirements for the production

of halal meat of high spiritual and conventional quality is

continuing.
