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.

  • Cleaning and sanitizingHigher risk

    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.

    Recorded 11 times across 8 separate inspections, most recently on December 10, 2024. For example: 4100 - Warewashing facilities properly installed, maintained, used; sanitizer concentration; test strips available and used

  • Handwashing and staff hygieneHigher risk

    Hands are the main way germs like norovirus move from people to food. Inspectors look for stocked, accessible handwashing sinks, staff washing hands when required, hair restraints, and sick employees being kept away from food. Gaps here can spread illness quickly.

    Recorded 8 times across 6 separate inspections, most recently on June 7, 2017. For example: 0600 - Adequate handwashing facilities

  • Food temperature controlHigher risk

    Bacteria multiply fastest between about 4 °C and 60 °C (40 °F to 140 °F). Inspectors check that cold food stays cold, hot food stays hot, cooked food is cooled quickly, and that staff have accurate thermometers. Temperature problems are one of the most common causes of food poisoning, so these are treated as critical findings.

    Recorded 6 times across 6 separate inspections, most recently on December 5, 2023. For example: 2200 - Accurate thermometer provided and used to evaluate temperature of TCS foods

  • Protecting food from contaminationHigher risk

    This covers how food is stored, prepared and displayed: raw meat kept away from ready-to-eat food, food covered and stored off the floor, and nothing dripping or splashing into it. Cross-contamination from raw to cooked food is a direct route for salmonella and E. coli.

    Recorded 6 times across 6 separate inspections, most recently on May 24, 2016. For example: 1400 - Raw meats below and away from ready to eat food; species separated

  • Food safety training and certificationLower risk

    Most jurisdictions require a certified food handler or manager on site, and some require allergen or food-worker training. These findings mean the paperwork or the trained person was missing at the time. They do not by themselves mean food was handled unsafely.

    Recorded 4 times across 3 separate inspections, most recently on May 30, 2025. For example: 0100 - PIC present, demonstrates knowledge and performs duties to maintain AMC; certified manager on staff unless exempt
