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 once on January 22, 2026. For example:
THERMOMETERS PROVIDED AND ACCURATE
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 4, 2024. For example:
NO RODENTS, INSECTS, BIRDS, OR ANIMALS
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 6 times across 3 separate inspections, most recently on January 22, 2026. For example:
EQUIPMENT/UTENSILS APPROVED: INSTALLED; GOOD REPAIR; CAPACITY
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 5 times across 3 separate inspections, most recently on January 22, 2026. For example:
FLOORS, WALLS AND CEILINGS PROPERLY BUILT, MAINTAINED AND CLEAN
Food safety training and certificationLower risk
Most jurisdictions require a certified food handler or manager on site, and some require allergen or food-worker training. These findings mean the paperwork or the trained person was missing at the time. They do not by themselves mean food was handled unsafely.
Recorded once on January 22, 2026. For example:
FOOD SAFETY CERTIFICATION
