摘要: According to the present invention there is disclosed a system (100) and metiod for detecting presence of human fecal contamination on object, such as protein source, worker's hands, work surfaces, tools or utensils. In one embodiment, included supporting structure (110) which supports diffuse light source (EO), emitting having wavelength from blue portion electromagnetic spectrum effective elicit fluorescence matter at wavelengths in 600 nm 800 range. A third interest m range also used reference control. Thereafter are combined series mathematical step develop an algorithm process detect material. There method using device (170) contamination, optionally including further steps identify any modify practices so that spread may be reduced.
