ABSTRACT:
A method for remvoing hair from the hide of an animal to be slaughtered in order to reduce bacterial contamination of meat and meat by-products.
A bovine is first immobilized and a depilatory substance of sodium sulfide is sprayed onto the animal's hide for 1-60 seconds. After a dwell time of about 1-180 seconds, the hair contacted by the depilatory substance is removed by directing pressurized jets of water at the animal's hide. Neutralizing agents are then sprayed onto the animal to stop the depilatory process and the animal is conveyed to an exsanguination station for further processing.
