Scientists with USDA and IowaStateUniversity have
conducted research on a fluorescence-based method of detecting central
nervous system tissues on beef cattle in real time, according to a report in
the Journal of Agricultural and Food Chemistry.
The procedure utilizes the fact that nervous system tissues contain high
concentrations of lipofuscin, which fluoresces when
it is exposed to light. The research detected even small amounts of bovine
spinal cord in the presence of raw bovine skeletal muscle, fat and vertebrae
by analyzing the fluorescence with a spectrometer.
