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 on March 20, 2024. For example:
THERMOMETERS PROVIDED AND ACCURATE
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 March 20, 2024. For example:
WIPING CLOTHS: PROPERLY USED AND STORED
PestsHigher risk
Signs of mice, rats, cockroaches or flies, or gaps and clutter that let them get in or hide. Pests carry bacteria and can contaminate food and surfaces, so evidence of activity is treated seriously and usually triggers a follow-up visit.
Recorded once on March 20, 2024. For example:
PREMISES; PERSONAL/CLEANING ITEMS; VERMIN-PROOFING
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 4 times across 2 separate inspections, most recently on June 10, 2026. For example:
FLOORS, WALLS AND CEILINGS PROPERLY BUILT, MAINTAINED AND CLEAN
Equipment and utensilsLower risk
Equipment has to be built from cleanable materials, kept in good repair and stored properly. These findings are mostly about upkeep, like a cracked shelf, a worn gasket or utensils stored the wrong way. They are generally lower risk but show how well the kitchen is maintained.
Recorded 3 times across 2 separate inspections, most recently on June 10, 2026. For example:
NON-FOOD CONTACT SURFACES CLEAN
