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.
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 April 28, 2026. For example:
PREMISES; PERSONAL/CLEANING ITEMS; VERMIN-PROOFING
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 April 28, 2026. For example:
ADEQUATE HANDWASHING FACILITIES; SUPPLIED & ACCESSIBLE
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 December 30, 2025. For example:
PROPER HOT AND COLD HOLDING TEMPERATURES
Food source, labelling and allergensHigher risk
Food must come from approved suppliers, stay in labelled containers and be thrown out when it is spoiled or damaged, such as dented or swollen cans. Labelling matters for allergies: an unlabelled container can hide an allergen.
Recorded once on December 30, 2025. For example:
IMPOUNDMENT/VOLUNTARY CONDEMN AND DISPOSE (VC&D)/SAMPLING
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 6 times across 4 separate inspections, most recently on April 28, 2026. For example:
ADEQUATE VENTILATION AND LIGHTING; DESIGNATED AREAS, USE
