  • Rectal plug and method of introducing same into a slaughtered animal
    Patent number: 5494481
    Abstract: Fecal leakage and contamination from the vent opening of an animal carcass during slaughtering and processing is eliminated by injecting a highly viscous material comprising a mixture of food grade constituents through the vent opening so as to create a self-adhering plug in the lower colon and rectum of the animal. The plug material preferably comprises a blended mixture of water, gum, modified food starch and a preservative whose viscosity is in the range of from about 220,000 centipoise to 480,000 centipoise. Being formed from food grade constituents, the offal can safely be harvested and used in animal feed as a by-product of the meat processing operation.
