Acoustic pressure shock waves used with segment parabolic reflector for meat processing

A method of cleaning an animal carcass comprising:

• providing an animal carcass adjacent an acoustic pressure shock wave applicator having a segment parabolic reflector including a reflector wall that is a longitudinal segment of a paraboloid that includes a focal point and longitudinal axis of the paraboloid such that the reflector wall does not fully extend 360 degrees around the longitudinal axis;
• and
• generating acoustic pressure shock waves from the focal point and applying resulting pseudo-planar shock waves to reduce contaminants on the carcass, wherein the resulting shock waves have a compressive phase producing high compressive pressure followed by a tensile phase and further comprising applying the resulting shock waves through a clean liquid drape to the carcass.
