Abstract

Sanitation inspection is an ongoing concern for food distributors, restaurant owners, caterers, and others who handle and serve food. They must prevent food contamination but now must also deal with potential infection spread among workers and customers. Beyond zero tolerance legal requirements and damage to institutional or restaurant reputation, loss of trust with workers and customers can be very costly. We provide fluorescence imaging results that were measured, analyzed, and recorded on different high touch surfaces in restaurants and institutional kitchens. We have developed an algorithm to classify cleanliness levels based on the extent of organic residues detected.
