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 September 22, 2026. For example:
ADEQUATE HANDWASHING FACILITIES; SUPPLIED & ACCESSIBLE
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 2 times across 2 separate inspections, most recently on September 22, 2026. For example:
IMPOUNDMENT/VOLUNTARY CONDEMN AND DISPOSE (VC&D)/SAMPLING
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 January 30, 2024. For example:
FOOD CONTACT SURFACES: CLEAN AND SANITIZED
Protecting food from contaminationHigher risk
This covers how food is stored, prepared and displayed: raw meat kept away from ready-to-eat food, food covered and stored off the floor, and nothing dripping or splashing into it. Cross-contamination from raw to cooked food is a direct route for salmonella and E. coli.
Recorded once on January 30, 2024. For example:
FOOD PROPERLY STORED; FOOD STORAGE CONTAINERS IDENTIFIED
Permits, records and postingLower risk
Operating permits, required signage, written procedures and logs. These findings are administrative: the documentation was missing or out of date at the time of inspection.
Recorded 2 times across 2 separate inspections, most recently on September 22, 2026. For example:
