Abstract
A method for sanitizing poultry carcasses utilizing ozonated water applicable to a mass poultry processing facility. Ozonated water is produced to a concentration of at least 0.5 parts per million ozone in water and introduced into a trough through which partially processed poultry carcasses can be fully immersed. The trough is equipped with rows of nozzles along the bottom that are directed into the trough to stream jets of ozonated water into the inner body cavity of a poultry carcass and at the back side of the carcass as it moves through the trough. The trough is filled with ozonated water, at a temperature of about 33.degree. F., in addition to the jets of ozonated water from the nozzles. The carcasses are immersed into the trough at a downstream location and move through the trough upstream against the flowing ozonated water. The carcass is placed on a rack that holds the carcass upright while moving through the trough. The bacteria present on a carcass is substantially reduced following treatment by the method of this invention.
