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 13 times across 11 separate inspections, most recently on June 15, 2023. For example: 3000 - Proper thawing methods used

  • 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 6 times across 5 separate inspections, most recently on December 7, 2022. For example: 4100 - Warewashing facilities properly installed, maintained, used; sanitizer concentration; test strips available and used

  • 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 once on May 18, 2012. For example: 3100 - Proper labeling, signage

  • 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 once on September 19, 2007. For example: Adequate handwashing facilities

  • 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 January 4, 2024. For example: 4400 - Plumbing properly sized, installed, and maintained; proper backflow devices, indirect drains, no cross-connections
