Lede: Do restaurant bathroom signs saying “Employees must wash hands” make you feel more comfortable? A new device is making sure workers hands are really clean.

Randy Atkins: Called PathSpot, it’s about the size of a shoebox and attaches to the wall near the restaurant sink. After washing and drying, employees put their hands underneath to be bathed in a special wavelength of light.

Christine Schindler: We’re scanning those hands for specific contaminants that could make people sick and we reflect that back into our device.

Randy Atkins: Christine Schindler, the startup company’s CEO, says then their algorithm can instantly determine if bugs like Salmonella, E-coli, or Norovirus – among others – are present. If so, a red warning light comes on…signaling a need to re-wash, and re-scan. It also tracks data, such as results of specific employees.

Christine Schindler: We lease the units and the data components as well as our expert team to help identify gaps in sanitation procedures and customize training for the establishment.

Randy Atkins: Schindler says PathSpot could find future uses ranging from warning of flu in the office to peanut allergy concerns in school. With the National Academy of Engineering, Randy Atkins, WTOP News.
