Method and system for detecting fecal and ingesta contamination on the carcassesof meat animals

摘要

A method and apparatus for detecting ingesta or fecal contamination on an animal carcass using fluorescent spectroscopy is disclosed. The surface of the carcass is illuminated with UV or visible light having an appropriate wavelength and fluorescent light emissions having a wavelength between about 660 to 680 nm are then detected. The emission of fluorescent light having wavelengths between about 660 to 680 nm is an indication of the presence of ingesta or fecal material on the carcass.
