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.

• 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 across 2 separate inspections, most recently on April 1, 2026. 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 2 times across 2 separate inspections, most recently on March 27, 2024. For example: 4400 - Plumbing properly sized, installed, and maintained; proper backflow devices, indirect drains, no cross-connections
