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.

  • 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 10 times across 8 separate inspections, most recently on August 5, 2025. For example: 2120 - Proper cold holding temperatures; between 42 to 45 degrees Fahrenheit (F) (6 to 7 degrees Celsius (C))

  • 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 5 times across 4 separate inspections, most recently on September 11, 2026. For example: 3400 - Wiping cloths properly used, stored; sanitizer concentration

  • 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 5 times across 5 separate inspections, most recently on January 19, 2024. For example: 0600 - Adequate handwashing facilities

  • 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 16, 2019. For example: 3300 - Potential food contamination prevented during delivery, preparation, storage, display

  • Food source, labelling and allergensHigher risk

    Food must come from approved suppliers, stay in labelled containers and be thrown out when it is spoiled or damaged, such as dented or swollen cans. Labelling matters for allergies: an unlabelled container can hide an allergen.

    Recorded 2 times across 2 separate inspections, most recently on August 5, 2025. For example: 3100 - Food properly labeled; proper date marking
