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.
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 4 times across 3 separate inspections, most recently on August 24, 2026. For example:
FOOD STORAGE; FOOD STORAGE CONTAINERS IDENTIFIED
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 3 times across 2 separate inspections, most recently on August 24, 2026. For example:
PROPER HOT AND COLD HOLDING TEMPERATURES
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 3 times across 3 separate inspections, most recently on August 24, 2026. For example:
PREMISES; PERSONAL/CLEANING ITEMS; VERMIN-PROOFING
Chemicals and toxic substancesHigher risk
Cleaning products, sanitizers and pesticides must be labelled and stored away from food and food-contact surfaces. Inspectors flag chemicals that could end up in food, as well as pest treatments applied without proper supervision.
Recorded 2 times across 2 separate inspections, most recently on August 24, 2026. For example:
TOXIC SUBSTANCES PROPERLY IDENTIFIED, STORED, AND USED
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 August 12, 2026. For example:
FOOD CONTACT SURFACES: CLEAN AND SANITIZED
