At a catering standpoint, I can tell you it works wonders for off and on sight catering.
I monitor all HACCP process cycles. From truck to table, I make sure that all food is safe through and through by observing the cooks health, use of gloves and utensils, handwashing techniques, time and temperature abuse, santitizing everything befor and after use.inspecting and storing all foodstuff the minute it arives. All buffet tables have a time and temperature check list. As well as the food dollies. Anyone not following procedures are given one warning and must pass a sanitation and safety test.
