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 4 times across 3 separate inspections, most recently on December 1, 2025. For example: Floors, walls, and ceilings clean and in good repair and maintained in a sanitary manner

• 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 3 times across 3 separate inspections, most recently on April 17, 2025. For example: Hand washing basin with supplies of soap and paper towels in dispensers

• 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 3 times across 3 separate inspections, most recently on April 17, 2025. For example: Mechanical dishwashing: Wash / rinse water clean, water temperature, timing cycles, sanitizer

• 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 3 times across 3 separate inspections, most recently on September 16, 2024. For example: Equipment, utensils, multi-service articles and all food contact surfaces are properly constructed

• 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 2 times across 2 separate inspections, most recently on December 1, 2025. For example: Separate hand washing basin provided for food handlers
