Apparatus and method for detecting fecal and ingesta contamination using a hand held illumination and imaging device

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