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.

  • 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 3 times across 3 separate inspections, most recently on May 27, 2026. For example: TOXIC SUBSTANCES PROPERLY IDENTIFIED, STORED, AND USED

  • 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 on April 25, 2025. For example: HANDS CLEAN AND PROPERLY WASHED; GLOVES USED PROPERLY

  • 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 once on May 27, 2026. For example: PROPER COOLING METHODS

  • 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 once on May 27, 2026. For example: FOOD SAFETY CERTIFICATION

  • Building, plumbing and upkeepLower risk

    Floors, walls and ceilings must be smooth and clean, with working lighting, ventilation, plumbing, hot and cold water, and washrooms. These are rarely an immediate food-safety risk on their own, but persistent problems can lead to pest or sanitation issues.

    Recorded once on April 25, 2025. For example: FLOORS, WALLS AND CEILINGS: PROPERLY BUILT, MAINTAINED IN GOOD REPAIR AND CLEAN
