Currently, there are five levels of food safety risk, from very low to very high. The change in inspections will occur in the low-level category. One example would be a bar where frozen pizza is served to patrons. None of the other categories where food is prepared in a kitchen will see a change in inspections.
Risk Level 2 (low risk): Inspected every five years, although inspectors can increase the number of visits if deemed necessary. These are sandwich shops that don’t cook, snack bars, convenience stores and pizzerias that use pre-cooked ingredients. Examples: Subway, Costco, Cinnabon, Dunkin’ Donuts, Domino’s, Firehoude Subs, Five Guys, Jimmy John’s and Papa Murphy’s.
I don't know about you, but I've seen some sub places. 5 years is a long time to not have food storage checked.
