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 20 times across 16 separate inspections, most recently on February 26, 2020. For example: 2120 - Proper cold holding temperatures ( 42° F to 45° F)

  • 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 8 times across 8 separate inspections, most recently on February 26, 2020. For example: 3400 - Wiping cloths properly used, stored, proper sanitizer

  • 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 4 times across 4 separate inspections, most recently on August 7, 2018. For example: 0400 - Hands washed as required

  • 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 2 times across 2 separate inspections, most recently on August 7, 2018. For example: 3300 - Potential food contamination prevented during delivery, preparation, storage, display

  • 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 6 times across 6 separate inspections, most recently on August 30, 2018. For example: 4400 - Plumbing properly sized, installed,...
