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 9 separate inspections, most recently on July 23, 2026. For example: 1900 - No room temperature storage; proper use of time as a control, procedures available

  • 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 9 times across 8 separate inspections, most recently on January 12, 2026. For example: 3400 - Wiping cloths properly used, stored; sanitizer concentration

  • 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 7 times across 6 separate inspections, most recently on July 23, 2026. For example: 1400 - Raw meats below and away from ready-to-eat food; species separated

  • 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 4 separate inspections, most recently on January 12, 2026. For example: 0600 - Adequate handwashing facilities

  • Chemicals and toxic substancesHigher risk

    Cleaning products, sanitizers and pesticides must be labelled and stored away from food and food-contact surfaces. Inspectors flag chemicals that could end up in food, as well as pest treatments applied without proper supervision.

    Recorded 2 times across 2 separate inspections, most recently on January 12, 2026. For example: 2500 - Toxic substances properly identified, stored, used
