Abstract: According to the present invention, there is disclosed a system and a method for detecting the presence of fecal contamination or ingesta on objects, such as a protein source, a worker's hands or utensils. In one embodiment, there is included a supporting structure which supports a diffuse light source, the light source emitting light having a wavelength effective to elicit fluorescence from the ingesta or fecal matter at a wavelength between about 660 to 680 nm into an area adjacent to the system, and a light detection device to detect light at a wavelength between about 660 to 680 nm from the area adjacent to the system. The detection of light at a wavelength between about 660 to 680 nm indicates the presence of fecal contamination or other ingesta. There is also disclosed a method of using such a device to detect the presence of such contamination, optionally including further steps to identify the source of any contamination and to modify any practices so that the spread of contamination may be reduced.

Abstract: According to the present invention, there is disclosed a hand-held system and a method for detecting the presence of fecal contamination or ingesta on objects, such as a protein source, a worker's hands or utensils. In one embodiment, there is included a system comprised of a housing having a first end, where said housing supports a light source which emits light out of said housing first end having a wavelength effective to elicit fluorescence at a wavelength between 660 to 680 nm, and a light filter allowing the user to distinguish light at a wavelength between about 660 to 680 nm from any other light the vicinity of the object. The detection of light at a wavelength between about 660 to 680 nm indicates the presence of fecal contamination or other ingesta. There is also disclosed a method of using such a device to detect the presence of such contamination, optionally including further steps to identify the source of any contamination and to modify any practices so that the spread of contamination may be reduced.

Abstract: A fluorescent spectroscopic method and apparatus for real time direct detection of transmissible spongiform encephalopathies in central nervous system tissue by monitoring the fluorescence of intrinsic markers in the tissue by illuminating the tissue with UV or visible light having an appropriate wavelength, and the resulting emission spectra is detected and examined in the region from 350 to 650 nm. A higher intensity in this region is indicative of infected tissue. The apparatus and method would not interfere with existing slaughterhouse line speeds or procedures, and could be used on live animals.
