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 2 times across 2 separate inspections, most recently on October 14, 2026. For example: 1720 - Proper hot holding temperatures; between 130 to 134 degrees Fahrenheit (F) (54 to 56 degrees Celsius (C))

• 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 November 7, 2025. For example: 4400 - Plumbing properly sized, installed, and maintained; proper backflow devices, indirect drains, no cross-connections
