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.

  • 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 2 times across 2 separate inspections, most recently on September 22, 2026. For example: FOOD SEPARATED AND PROTECTED

  • 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 2 times across 2 separate inspections, most recently on June 10, 2025. For example: WIPING CLOTHS: PROPERLY USED AND STORED

  • 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 once on June 10, 2025. For example: PROPER HOT AND COLD HOLDING TEMPERATURES

  • Equipment and utensilsLower risk

    Equipment has to be built from cleanable materials, kept in good repair and stored properly. These findings are mostly about upkeep, like a cracked shelf, a worn gasket or utensils stored the wrong way. They are generally lower risk but show how well the kitchen is maintained.

    Recorded 7 times across 3 separate inspections, most recently on September 22, 2026. For example: EQUIPMENT/UTENSILS APPROVED: INSTALLED; GOOD REPAIR; CAPACITY

  • 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 3 times across 3 separate inspections, most recently on September 22, 2026. For example: FOOD SAFETY CERTIFICATION
