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 13 times across 11 separate inspections, most recently on May 1, 2023. For example: 3300 - Potential food contamination prevented during delivery, preparation, storage, display

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

  • 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 11 times across 7 separate inspections, most recently on March 11, 2024. For example: 1720 - Proper hot holding temperatures; between 130 to 134 degrees Fahrenheit (F) (54 to 56 degrees Celsius (C))

  • 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 November 5, 2009. For example: 0600 - Adequate handwashing facilities

  • 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 once on March 11, 2024. For example: 3200 - Insects, rodents, animals not present; entrance controlled
