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.

• 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 once on February 24, 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 once on July 19, 2023. For example: 1100 - Proper disposition of returned, unsafe, or contaminated food; proper date marking procedures for food at high risk for Listeria

• 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 March 29, 2014. For example: 0600 - 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 March 29, 2014. For example: 4400 - Plumbing properly sized, installed,...

• Other findingsLower risk

  Findings that do not fit the categories above, such as follow-ups that confirm an earlier violation was corrected, or requirements specific to this type of facility.

  Recorded once on April 23, 2019. For example: 0900 - Proper washing of fruits and vegetables
