Abstract

A cleansing solution is formed by injecting a pressurized gas into a liquid, subjecting the liquid to high shear forces to divide the gas into small bubbles, and pressurizing the gas to cause a significant portion of the bubbles to become dissolved in the liquid. The cleansing solution is depressurized and applied to an animal carcass, enabling the dissolved gas to come out of solution as bubbles. The bubbles lift contaminants from the surface of the carcass by migrating outwardly from the carcass surface to the air-liquid interface.
