What these findings mean

Health authorities word their violations differently, so we group them by what they mean for food safety. Higher-risk findings are the ones inspectors treat as critical, because they can directly make someone sick.

  Anything that touches food, such as cutting boards, dishes and utensils, must be washed, rinsed and sanitized. Inspectors check dishwasher temperatures, sanitizer strength and how wiping cloths are stored. Poor sanitizing lets bacteria survive from one use to the next.
