9.1). In general, the following steps for slaughtering can be distinguished: Besides, the use of wine in religious ceremonies is regarded as acceptable by certain groups. Animals Aren’t The Only Ones Affected, So Are The Workers Image via WeAnimals. It has been reported that exposure of pigs to either argon-induced anoxia or the carbon dioxide–argon mixture for 3 min resulted in satisfactory stunning; however, bleeding should commence within 15 s to avoid resumption of consciousness. Relevant verses of the Quran For halal slaughter, no special knife design is required. Slaughtering of animals Slaughter: The act of killing or butchering of animals in a "correct" way especially for food. Countries differ in the methods which have been legalised for different species or different ages, some r… Combinations of techniques based on different principles may result in greater sensitivity. Direct or progressive exposure of conscious pigs and poultry to an inert gas mixture such as argon or nitrogen leading to anoxia. The caselife of a beef cut, i.e. The primary steps in processing livestock include rendering and bleeding, scalding and/or skin removal, internal organ evisceration, washing, chilling, and cooling, packaging, and cleanup. An incision (sticking) which severs the major arteries of the neck or anterior thoracic cavity causes a rapid loss of blood, resulting in a lack of oxygen to the brain. Whole blood proteins exhibit emulsification capacities and emulsion stabilities equal to or greater than that of proteins of other organ and tissue concentrates including muscle proteins [716]. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Among the secondary lipid oxidation products found in meat are various aldehydes of different molecular weight and degree of unsaturation. Electroanesthesia is widely used for the stunning of slaughter animals. Better quantitative methods, including real-time PCR procedures, must be developed. Oxidation of MbFe(II)O2 may be the first step in a chain of events leading to oxidative changes in lipids, and vice versa, oxidized muscle lipids and liposomes can catalyse the browning of meat haemoproteins (Monahan 2000). Stress applied to livestock before slaughter can lead to undesirable effects on the meat produced from these animals, including both PSE and DFD (see Postmortem quality problems). The carcasses are then split down the centre of the backbone into two “sides,” which are placed in a cooler (called a “hot box”) for approximately 24 hours before fabrication into meat cuts. Fish, which were able to move freely, initially showed limited tonic/clonic cramps, followed by heavy clonic contractions combined with uncoordinated movements or turning aside. At this point in the process, the slaughtering procedures begin to differ by species. The three most common methods of stunning are mechanical, electrical, and carbon dioxide (CO2) gas. Her designs enabled workers to move animals without frightening them. After cleaning and dehairing, heads are removed and carcasses are opened by a straight cut in the centre of the belly to remove the viscera (the digestive system including liver, stomach, bladder, and intestines and the reproductive organs), pluck (thoracic contents including heart and lungs), kidneys, and associated fat (called leaf fat). In terms of the diseases mentioned in Table 4.6, evidence of parasitic infestation will be the most likely indication of action being required at post-mortem meat inspection. Some reports concerning blood separation [722] and fractionation in industrial scale [724] encourage using membrane processes for simultaneous recovery of water from waste effluents – NF [725], NF/UV integrated system [726]. In beef meat the initial purplish-red colour turns to bright-red in about 30 min after exposing the cut surface to air. uterine fluids and placenta), aerosol or by handler, Use good quality straw and remove placentas from lambing yards. Recently, methods have been described for detecting Campylobacter in faeces (Lund et al., 2003, 2004; Rudi et al., 2004) and E. coli O157 in faeces and environmental samples (Ibekwe and Grieve, 2003). However, if it is necessary to use these means to calm down or mitigate violence of animals, low voltage shock can be used on the head … Eradication programs usually require an abortion notification and investigation scheme as well to detect infection. Heads are removed at the first cervical vertebra, called the atlas joint. Once restrained, the animal is stunned to ensure a humane end with no pain. For instance, the use of caffeine is prohibited or restricted by many religions because of its addictive properties and harmful physical effects. UF is also 50% less expensive than vacuum evaporation for animal blood concentration [721] Optimum parameters of concentrating blood plasma by UF have been presented in many papers [722], including influence of feed flow rate, membrane pore size, and pressure on protein concentration [661, 723]. Slaughtering is the killing, cleaning, skinning and quartering animals for meat. Stunning also results in decreased stress of the animal and superior meat quality. Plasma and globe protein isolates prepared from slaughter blood are ideal emulsifiers under optimum conditions of pH and protein concentration [717]. Much work was also conducted on protein recovery from wastewater by UF [716]. The slaughter of livestock involves three distinct stages: preslaughter handling, stunning, and slaughtering. In the sheep flock there is the additional concern for the health of the stockman from zoonoses which cause abortion, such as Chlamydia psittaci, Toxoplasma gondii, Campylobacter spp., Salmonella spp., and the use of chemicals, e.g. Several studies involving sheep, in which neurotransmitters have been measured, coupled with pharmacological experiments, suggest the general epileptiform insult induced by an electrical stun is dependent on the release of vasopressin, oxytocin, glutamate, aspartate, and gamma amino-4-butyric acid (GABA). The slaughter must comply himself as a true Muslim. CO2 stunning exposes the animal to a mixture of CO2 gas, which acts as an anesthetic. In the latter case, the biogas is produced as the source of energy recovery. Hogs are usually stunned by electrical means or CO2 gas. To ensure that a HACCP plan applied to a sheep flock remains simple and workable it must be separated from any flock health scheme. There is an interrelation between the undesirable changes in colour and the lipid oxidation in meat. The “slaughtering” is to be done by cutting the throat, windpipe, and the blood vessels in the neck causing the animal's death without cutting the spinal cord. Animals are sent to slaughter crammed into trucks that can travel long distances while banned from food and water. In sheep as well as in other mammals the extensors are stronger than the flexors that caused the extension. Quantifying some pathogens, such as Salmonella and E. coli O157, still depends on labour-intensive MPN methods. She also maintained that her acute visualization could be harnessed in making design decisions regarding other matters. Recommended minimal current for electrical stunning of poultry, ruminants, pigs, and fish. The economic implications of undesirable colour changes in beef and the effectiveness of the applied counter-measures have been discussed by Smith et al. Owing to the prolonged exposure time required to kill pigs with anoxia, it is not used under commercial conditions. Manteca (1998) says concern for animal welfare is a major consideration in meat production and is based upon the belief that animals can suffer. When the duration of exposure to this level of carbon dioxide is increased, the incidence of death also increases. The frequency can be as high as 1800 Hz, and the waveform can be square or rectangular. However, convulsions occurring as wing flapping after the loss of consciousness in poultry can increase the incidence of dislocated or broken wing bones. Blood contains about 18% proteins, almost as much as lean meat, and is sometimes referred to as liquid protein. As the slaughter process begins, livestock are restrained in a chute that limits physical movement of the animal. This is found to be at least as effective as electrical stimulation of carcasses, especially in poultry. Oxidation results in a change of the colour to the undesirable brown. The flexors and extensors in fish are considered to be equal in strength, which may explain the observation of limited tonic and clonic cramps. Many unsaturated aldehydes react readily with proteins, α, β-Unsaturated aldehydes may lead to colour changes by covalently binding to MbFe(II)O2 and thus by changing the conformation of the molecule, that results in exposure of the haeme iron to oxidation (Faustman and Wang 2000). Another sticking method, lateral stab incision of the neck, avoids incision of the trachea and esophagus, because this may result in aspiration of blood and pollution of the blood by stomach contents. Beyond the unimaginable suffering taking place in the minds of billions of animals every single year, the workers at slaughterhouses are also affected by the work they do. The knife is inserted in the midline, cranial of the sternum bone, so that the bicarotid trunk and anterior vena cava are incised. Slaughter methods prevailing throughout the world are governedeither by tradition, ritual or legislation depending upon the peopleand the country. Sikorski, G. Sikorska-Wiśniewska, in Improving the Fat Content of Foods, 2006. A transverse incision of the neck is a common method of bleeding sheep. Various techniques, which include anaerobic digestion, precipitation with ammonium sulfate, and MF, are used in the treatment of abattoir effluent. Further automation of immunoassays will result in greater sample throughput and reduced labour requirements. For example, Roman Catholics, Eastern Orthodox Christians, and certain Protestant denominations use wine as a sacramental product to represent the blood of Christ in communion services. The first stage of the process, usually called stunning, is meant to render the animal fully unconscious, and thus not susceptible to pain, but not necessarily dead. This is followed by the release of GABA that provides a period of analgesia and also assists in the recovery if the animal is not slaughtered. There may be a sector of the industry in which hand-milking is carried out, but mechanical milking equipment is readily available. Animals should be as clean as possible at slaughter. 1:12 A 5 min exposure to these gas mixtures followed by bleeding within 45 s prevented carcass convulsions during bleeding. Generalized epileptiform EEG consists of relatively small waves increasing in amplitude in the tonic phase and decreasing in frequency in the clonic phase to result ultimately in a period of strong depression of electrical activity in pigs, sheep, calves, and poultry (Figure 1). Halal slaughter is the Muslim method of killing animals for food. The administration of antioxidants to the livestock in order to improve the colour stability of meat has been also treated by Moloney in Chapter 13. Ritualistic or religious slaughter often requires the animal to bein a state of consciousness at the time it is bled. For a bleeding time of about 2 min, the pigs are conveyed in a horizontal position. The end result of each method is to render the animal unconscious. Instead, two other gas mixtures have been approved for killing domestic poultry intended for human consumption: Argon, nitrogen, or other inert gases, or any mixture of these gases, in atmospheric air with a maximum of 2% oxygen by volume. Thus, the Muslim way of slaughtering is more hygienic as most of the blood containing germs, bacteria, toxins, and others that cause several diseases are eliminated. Current methods for detecting pathogens in foods may not be optimal for other matrices, such as animal faeces, feathers, environmental samples, etc. Slaughtering procedure. The relatively small waves (initial phase) became larger (tonic phase) with an increase in amplitude and a decrease in frequency, followed by a period of strong depression of electrical activity (exhaustion phase) and recovery. Because of its high nutritional value, blood as food additive is cost-competitive in comparison with other proteins, such as soy and milk proteins, used in sausage formulations. The animal has to be lawful to eat, alive, healthy, and has to be slaughtered only for the name of Allah (s.w.t. UF concentration of blood proteins is faster, very simple, and the energy requirements are very low; are not thermal and do not alter the solute; and, finally, concentration, fractionation, and purification can be carried out simultaneously. The observed behavior of a general epileptiform insult is characterized by a phase of tonic muscle spasm followed by a phase of clonic muscle spasms and ultimately an exhaustion phase with muscle flaccidity. The UF PES membranes with a 40 000 MWCO and the RO membranes made of cellulose acetate were used to treat effluent from red meat abattoirs [727]. the time over which the meat retains the desirable bright-red colour and can be exhibited in retail display, prior to its being discounted in price, may reach from 1 to about 5 days. When positive results or abortions occur, safety measures should be undertaken and reactors or aborted females slaughtered. General principles 1. These methods must show no false-negative results and very few false-positives or, better still, none. In meat production, membranes are used for filtration, concentration, and deashing of pork, bone, or beef gelatin beef tallow clarification, gelatin primary clarification, meat brine clarification for bacteria removal and brine reuse, beef wash water porcine bovine blood plasma, and chicken blood, gelatin production. A beef animal selected for slaughter should be healthy and in thrifty condition. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V.

The spinal cord must not be cut because the nerve fibers to the heart could be damaged during the process causing cardiac arrest, stagnating the blood in the blood vessels. The main changes in meat pigments. The term slaughter is also used to depict killing of animals by bleeding. Most religious food are believed to have its own benefit especially when dealing with nutrition and health. Hogs are one of the few domesticated livestock animals in which the skin is left on the carcass after the slaughter process. However, further research and development is needed to evaluate the feasibility of inducing unconsciousness with anoxia and then killing pigs by other means (e.g., induction of cardiac arrest in unconscious pigs using an electric current). Fig. The most common electrical stunning method for livestock uses a frequency of 50 Hz alternating current (AC) with sinusoidal waveform. SLAUGHTER OF ANIMALS Article 7.5.1. Vacuum evaporation, freeze drying, and gel filtration are the processes that can be used for concentrating blood proteins without degrading their delicate and revenue-producing properties; however, UF of plasma proteins is more efficient than plasma freezing [718] or chemical coagulation. PCR-based systems employing an immunomagnetic step prior to detection produced fewer false-positive results (Arthur et al., 2005). Most farm animals are killed by bleeding. Although marijuana has been shown to control pain in advanced diseases such as cancer, it has been considered a restricted drug by all but those practicing Rastafarianism. If you send animals for processing, you must make sure that you or another person in charge of the animals completes an animal status declaration (ASD). Image: pig being abused in slaughter house bleeding to death after having throat slit whilst not properly stunned. Standardisation of newly developed methods will stimulate their use. Owing to this and the cost of argon, the poultry industry would prefer to use gas mixtures causing less of this quality problem, especially methods involving exposure to low or gradually increasing concentrations of carbon dioxide in air as these methods have been known to cause very little or no wing damage in the carcasses. The dry proteins have excellent gelling properties and emulsifying capacity and can be used for the production of yoghurt, cheese, and cakes [714]. We use cookies to help provide and enhance our service and tailor content and ads. B. Garin-Bastuji, in Encyclopedia of Dairy Sciences (Second Edition), 2011. - Slaughter of animals 2008 ©OIE - Terrestrial Animal Health Code 3. ii) The use of such devices should be limited to battery-powered goads on the hindquarters of pigs and large ruminants, and never on sensitive areas such as the eyes, mouth, ears, anogenital region or belly. following prophylaxis for watery mouth. Evisceration and splitting are similar to hog procedures, except that kidney, pelvic, and heart fat are typically left in beef carcasses for grading. A. Koltuniewicz, in Comprehensive Membrane Science and Engineering, 2010. I think there's a concern for humane treatment of the animals. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Clean and disinfect pens. It is a process that begins when the animal enters onto the kill floor or the area where they can be easily accessed to be slaughtered and ends in the cooling room. K. Troeger, in Encyclopedia of Food Sciences and Nutrition (Second Edition), 2003. In whole hog sausage production all the skeletal meat is trimmed off the carcass, and therefore the carcass is routinely skinned following exsanguination. However, on bird welfare grounds, this regulation does not allow the use of carbon dioxide for killing domestic poultry, except for disease-control purposes. Chapter 7.5. Ozone, ultraviolet radiation, and other disinfection processes are gaining acceptance due to stricter regulations on the amount of residual chlorine levels in discharged wastewaters. By continuing you agree to the use of cookies. Animal slaughter and processing produces very strong organic waste from body fluids, such as blood, and gut contents. (2000). Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. 9.1. Special attention should be given to the following aspects: For the release of perishable products in commerce and testing of slaughter animals for the presence of specific pathogens, there is a need for more rapid methods that give results within a maximum of a few hours. The carcasses are then placed in a dehairing machine, which uses rubber paddles to remove the loosened hair. Keeping Kosher is a very important aspect of Judaism because it benefits the mind, body, and soul; however non-Jews often consume Kosher meat because of the special process involved. Wastewater from slaughterhouses contains a large variety and quantity of contaminants, characterized mainly by a complex mixture of protein substances, lipids, and fibers. Inhumane transportation. Thus, the animal does not feel pain. Dietary supplementation of livestock with vitamin E is effective in delaying lipid oxidation and discoloration of fresh beef. Further development is needed for microarrays or ‘DNA chips’ and, in general, for molecular tests, so that they can become more user-friendly and suitable for application in routine laboratories. Since slaughtering animals is always violent and painful, some religions such as Islam and Judaism, decided to step in and regulate this practice, to make it less horrible. In ‘head to body’ stunning involving passage of a 50 Hz sine wave alternating current simultaneously through the brain and heart, the animal may die due to a heart failure, which is recordable on an electrocardiogram (ECG). Various carotenoids are able to decrease the rate of oxidation of MbFe(II)O2 and to reduce oxidized forms of myoglobin, thus increasing the colour stability of meat (Mortensen and Skibsted 2000). This method allows for maximal blood removal from the body. Also α-tocopherol, although it is lipid soluble, is known to stabilize MbFe(II)02 in beef. There are many diseases that pertain to the overall health and productivity of the flock and, possibly, to the quality of the meat but that will not directly affect human health. The animal must be alive at the time of slaughter. Irrespective of the species of animals involved, the ever-decreasing competition in the fields of stunning equipment manufacturing and gas distillation and distribution are disconcerting on economic grounds. The current technology of real-time PCR can be improved, resulting in more sophisticated high-throughput platforms and portable devices. All susceptible animals should be permanently identified and movements of animals closely controlled. Many countries have adopted the principle of a two-stage process for the non-ritual slaughter of animals to ensure a rapid death with minimal suffering. Preslaughter handling is a major concern to the livestock industry, especially the pork industry. A study was done to determine whether or not TMS with an adapted coil has potential for further development as a noninvasive stunning method for broilers and rabbits but further research and development is needed to optimize parameters. Several methods, including centrifugation and immunomagnetic separation, are used successfully and must be further developed and evaluated (Benoit and Donahue, 2003). In essence, the methods relate to the manner in whichthe animal is killed and bled and to some extent dressing and handlingprior to use as food. 4.05.2.17 Meat Industry. They stop feeding animals up to 24 hours before being sent to slaughter so there are no traces of food in their digestive system that impede the processing of the meat. Shechitah (sheh-HEE-tah) is the Jewish ritual of slaughtering permissible land animals and fowl so that they are considered Kosher and are able to be eaten by Jews. After stunning, animals are usually suspended by a hind limb and moved down a conveyor line for the slaughter procedures. Stunning also results in decreased stress of the animal and superior meat quality. Cancer, high blood pressure, and heart disease have all been linked to tobacco use. It depends on the reducing capacity of the muscles. In the United States the humane treatment of animals during each of these stages is required by the Humane Slaughter Act. During head-only stunning, broilers may display wing flapping during and after stunning, which is sometimes intensive. Easy-to-use, rapid agglutination tests for the identification of presumptive pathogens will remain of value in many routine laboratories (Baylis, 2003). In the U.S., under the Humane Slaughter Act, all livestock must be treated humanely. Preslaughter handling is a major concern to the livestock industry, especially the pork industry. The following are the conditions to slaughter animals based on Islamic method: The animal has to be slaughtered with a sharp object (knife) as fast as possible in order to reduce the pain of slaughter. Slaughter Houses and Meat Processing Facilities are Required to Minimize Animal Stress. Effective electrical stunning can be ascertained from the occurrence of generalized epileptiform activity in the brain by using EEG. The natural, cherry-red colour of beef meat on the fresh cut surface is due to the reduced forms of the muscle haemoproteins (Fig. Typically, chlorine (free or combined) is used to disinfect these wastewaters. The comments on milking cows are equally applicable to sheep, although the scale of the operation is usually smaller. In order to help more animals escape a fate of misery, please give vegan food a try. In addition to testing for well-established pathogens, more attention should be given to emerging types not generally sought in routine analyses. Contents Slaughtering of animals Processing of animals after slaughter Postmortem changes and ageing of meat 2 CVASU 3. For an easy start, join Challenge 22 to get free guidance and support for 22 days. There is a particular need for a universal pre-enrichment broth for the simultaneous enrichment of cells of injured pathogens belonging to different genera (Zhao and Doyle, 2001). Severing of the common carotid arteries or the vessels from which they arise during sticking can be done in different ways. A.M. Johnston, in HACCP in the Meat Industry, 2000. Dipsticks available for rapid screening of pathogens in enrichment cultures by lateral migration of an antigen–antibody complex will continue to be developed (Fung, 2002). The slaughter process has two stages: Stunning, when performed correctly, causes an animal to lose consciousness, so the animal can't feel pain.The law states that, with few exemptions, all animals must be stunned before 'sticking' (neck cutting) is carried out. An eye reflex cannot be used as an indicator, because the reflex is blocked during the tonic phase and may occur spontaneously during the clonic phase. Most methods are developed for detecting only one particular pathogen in a specified matrix. The slaughter process can represent different types of stress for every animal. Table 4.6. Wastewaters with high pathogenic levels must be disinfected prior to discharge. By contrast, stunning of pigs and poultry with argon and nitrogen mixtures or a mixture containing less than 30% by volume of carbon dioxide in argon or nitrogen mixture accelerates the rate of postmortem rigor development and tenderization of meat. Producers should wash their animals before leaving the farm. Z.E. Ahasanul Haque, ... Farzana Yasmin, in Preparation and Processing of Religious and Cultural Foods, 2018. Killing of slaughter animals is usually done by exsanguination (bleeding). It acts most probably by retarding the generation of primary lipid peroxides and the release of their water-soluble, pro-oxidative, free-radical breakdown products, predominantly unsaturated aldehydes or HOo radicals (Faustman and Wang 2000). 3 Essentials of Slaughter … In general, gas stunning/killing of pigs and poultry results in better carcass and meat quality than other established stunning methods. The blood has to be drained completely before the head is removed.
