MXPA97008986A - Rectal plug and method to introduce the same animal sacrific enun - Google Patents

Abstract

Faecal effusion and contamination of the cavity ventilation opening of an animal during killing or slaughter in processing is eliminated by injecting a highly viscous material comprising a mixture of food grade constituents through the vent opening in a manner that generates a self-adhesive plug in the lower colon and the rectum of the animal. The plug material preferably comprises a combined mixture of water, gum, modified food starch and a condom whose viscosity ranges from about 220.00 centipoise to 480,000 centipoise. The plug is made up of food-grade constituents, the waste can be collected safely and used in animal feed as a by-product of the car-processing operation.

Description

RECTAL PLUG AND METHOD TO INTRODUCE THE SAME IN A SACRED ANIMAL BACKGROUND OF THE INVENTION I. Field of the invention This invention relates generally to the processing of meat and poultry, and more particularly to a material, method and apparatus for preventing fecal contamination of the meat during the slaughter and disembowelment of animals whose meat is to be used for consumption. human .

II. Discussion of the Prior Art: A major concern in the processing of fattening animals is to prevent "fecal material, which is present in the rectum of an animal's intestine at the time of slaughter or sacrifice, from spilling over the body and causing contamination. Such contamination can result in the animal not meeting North American health inspection standards of the Department of Agriculture (USDA). Animal areas subject to fecal contamination should be cut and discarded, which REF: 26122 results in a financial loss to the processor and the breeder. In a typical line of poultry processing, the neck is cut from the birds and mounted upside down on a moving chain conveyor so that the blood is allowed to spill. Afterwards, the birds are placed in boiling water to loosen or lose the feathers and then they are advanced through a mechanical plucking machine. Afterwards, the birds are disembowelled. Faecal contamination can occur during the stages of plucking and disemboweling due to the compressive forces to which the animals are subjected, such as the plucking machine. These compressive forces can squeeze the intestines so they force fecal matter out through the anal opening. In U.S. Patent No. 5,083,975, for Neal et al. a method is described to solve the problem of spill of fecal matter of the corpse of an animal during the slaughter and the processing of the same one. According to the Neal '975 patent, a Krazy-Glue ™ cyanoacrylate adhesive is applied to the vent or anus of the carcass of an animal. The adhesive joins the fabric of the hole and holds it together so that it seals the opening. Although the method described in this prior art patent effectively prevents spillage of fecal material, because the cyanoacrylate adhesive is considered toxic, the waste can not be approved for use in dog food or the like.

BRIEF DESCRIPTION OF THE INVENTION According to the present invention, immediately after the animal slaughtered and suspended from a moving chain conveyor, a measured amount, which varies based on the size of the animal, is indicated in the anus or cloacal ventilation of the animal. Highly viscous food grade material which acts as a rectal plug, which prevents outflow or spillage of fecal material. Test results show that accidental cutting by workers in the gut line as the intestines are removed, "which eliminates the deposit of fecal material in the animal which may result in a lack of approval by federal inspectors. The plug material is a formulation of food grade substances that include a thermally stable gum, modified food starch or other thickener and a preservative that prevents degradation of plug material before use. The apparatus used to inject the material of the plug may comprise a piston pump, a peristaltic roller pump, or another type of device capable of extruding a measured quantity of the plug material in each actuation thereof sufficient to carry out the sealing of the plug. the anal opening or ventilation, but without causing rupture of the large intestine. A compressed air operated gun "having a tip that can be inserted into the opening or hole of the animal and that is designed to inject a predetermined volume of plug material each time it is actuated can also be used. Without limitation, the ingredients of the gum may constitute galactomannan gums which include locust bean gum and guar gum, carayá gum, tragacanth gum and xanthan gum. The modified food starch ingredient may comprise one or more starches derived from arrowroot, beans, buckwheat or buckwheat, corn, peas, potatoes, rice, barley, tapioca, waxy barley and waxy corn. Various condoms (antimicrobial agent) are also available for use in the formulation of the stopper according to the present invention. The gum, starch and preservative ingredients will be combined with water so that the resulting product preferably has a viscosity in the range of 220,000 to 480,000 centipoise.

The plug material of the present invention is safe for use in animal feeds which can be manufactured from by-products (wastes) of the fattening animals. A further advantage of the invention is that its viscosity is not appreciably lost when heated and, therefore, can withstand the scalding or boiling step of the poultry used to loosen the feathers without losing their effectiveness as a seal for the hole.

DESCRIPTION OF THE PREFERRED MODALITY The present invention comprises a rectal plug constituted of a mixture of viscous food-grade material together with a method for injecting the material into the rectum of sacrificed animals to avoid faecal contamination during processing. Although the material of the present invention is suitable for use in the processing of poultry, especially chickens and turkeys, it is also suitable for use in the processing of other fattening animals, including pigs and livestock. The food grade material of the rectal plug contains a mixture of water, one or more gums that are selected for their viscosity and thermal properties, modified food starch as a thickener and a suitable condom. Without wishing to be limited, suitable gums may be selected from agar, carrageenan and galactomannan gums, such as locust bean gum and guar gum. The guar gum itself is not gelling and can be used as a viscosity binder and a water binder. Guar gum interacts synergistically with xanthan gum, which provides an increase in the viscosity of the solution. Alternative gums can be selected from the aforementioned classes as exudate gums, with tragacanth gum being preferred due to its high viscosity properties and its heat stability. As mentioned, other ingredients used in the formulation of the rectal plug material include modified food starches and preservatives. The right candidates for each of these are as follows: Modified food starches Arrowroot Beans Buckwheat or Buckwheat Corn Pea Papa Rye Rice Tapioca 5 Waxy barley Waxy corn Wheat Combinations of the above Preservatives Antimicrobial agents Acetic acid Adipic acid Benzoates 15 Benzoic acid Citric acid Coagulable meat proteins Dehydroacetic acid and its sodium salt Fumaric acid 20 Gluconodeltalactone Lactic acid Water mixed with liquid alcohol, malic acid Natamycin 25 Nicin Nitrites (can alter the color of meat; not very likely) O-Phenylphenate, Sodium salt, Parabens Hydrochloride Parahydroxybenzoic acid Phosphoric acid Potassium benzoate Potassium sorbate Propionate propionic acid Sodium lactate Sodium diacetate Sorbate Sorbic acid Succinic acid Tannic acid Tartaric acid Vinegar It may also be found appropriate to include other thickeners in the formulation to obtain the desired viscosity for the material. These may include one or more of one of the following, in combination.

Other thickeners Amaranth flour Carboxymethylcellulose Cotton bean proteins Milk proteins Egg proteins Heat-coagulable proteins Microcrystalline cellulose Sorghum flour Mustard meal Oatmeal Peanut meal Pectin Protein hydrolysates Soy proteins Triticale flour Example I: A mixture comprising 2% by volume of guar gum and 1% xanthan gum, 15% modified food starch (wheat starch) and 0.5% propylparaben, and the remainder of water was well combined. It is found that the final product has a viscosity that exceeds 220,000 centipoise. Four to six grams of the product were injected through a nozzle into the holes of 200 turkeys. After bleeding and before submitting to boiling water, plucking and disemboweling them. It was found that the rectal plug prevents the exudation of fecal material outside, through the hole during the processing operations.

Example II: A mixture "comprising 7% by volume of guar gum, 25% modified corn starch (potato starch), 3.5% propylparaben as a preservative and the rest of water, showed a viscosity of approximately 480,000 centipoise. The mixture was placed in a storage container and then subsequently pumped using a plunger pump. The tapered nozzle attached to the end of the line was inserted into the anus and rectum of the animal and fired. Four to six grams of the product were injected, the amount is sufficient to allow the plug material to penetrate one part inward into the colon. When the nozzle is removed, the viscous material of the rectal plug is found to adhere to the inner walls of the intestine and rectum to form a complete seal and no traces of fecal material are found to 'spill past the seal so as to contaminate the corpse. Even under heavy impact forces to which the corpse is subjected by the equipment of the plucking machine, because the plug material is injected deep into the colon, no leaks occur as would be the case of a surface seal of the type obtained using the method of the '975 Neal patent in which the tearing of tissue close to the hole can destroy its integrity. This invention has been described herein in considerable detail in order to comply with the patent statutes and to provide those familiar with the art with the information necessary to apply the novel principles and to construct and use such specialized components as required. However, it should be understood that the invention can be carried out by specifically different equipment and devices, and that various modifications can be made to both the equipment details and the operating procedures, without departing from the scope of the invention. invention itself. It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects to which it relates. Having described the invention as above, property is claimed as contained in the following:
