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 9 separate inspections, most recently on December 1, 2025. For example: Equipment, utensils, multi-service articles and all food contact surfaces are properly constructed and maintained

  • 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 4 separate inspections, most recently on December 1, 2025. For example: Food is protected from contamination and adulteration

  • 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 2 separate inspections, most recently on March 16, 2026. For example: Potentially hazardous food is maintained at 4°C (40°F) or lower

  • 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 2 times across 2 separate inspections, most recently on August 4, 2026. For example: Handwashing stations are maintained and adequately supplied

  • PestsHigher risk

    Signs of mice, rats, cockroaches or flies, or gaps and clutter that let them get in or hide. Pests carry bacteria and can contaminate food and surfaces, so evidence of activity is treated seriously and usually triggers a follow-up visit.

    Recorded 2 times across 2 separate inspections, most recently on October 2, 2024. For example: Pest control is maintained
