Abstract

The poultry or meat is exposed to excitation light of a selected bandwidth(s) and certain bandwidth(s) is(are) measured and compared to a threshold, above which indicates contaminants. Suitable excitation bandwidth and measuring bandwidth are selected such that the ratio of or difference between the resulting sample fluorescence and contamination fluorescence are greater than a certain ratio or difference. If contaminants are present, a controller can generate a signal and/or send the contaminated items to a wash station.
