Abstract
We evaluate a handheld multispectral fluorescence imaging device to detect a bacterial colony on leafy greens. The most common diseases causing illness transmitted by leafy vegetables are norovirus, Shiga toxin-producing E. coli (STEC), and Salmonella, according to a CDC. Listeria and Cyclospora can also cause these illnesses. We will test the efficacy of a Contamination, Sanitization Inspection, and Disinfection (CSI-D) system using light at two fluorescence excitation wavelengths, ultraviolet C (UVC) at 275 nm and violet at 405 nm. Tests will evaluate the detection efficacy of device on inoculated control specimens of leafy greens during a time lapsed study.
