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 5 times across 5 separate inspections, most recently on September 29, 2026. For example: Adequate protection against the entrance of insects, vermin, and rodents

  • 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 3 separate inspections, most recently on August 6, 2026. For example: Potentially hazardous food is held at 4°C (40°F) or lower

  • 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 3 times across 3 separate inspections, most recently on August 6, 2026. For example: Food contact surfaces properly designed, constructed, installed, maintained, located (smooth, non-absorbent, cleanable, corrosion resistant and non-toxic)

  • 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 August 6, 2026. For example: Food protected from potential contamination and/or adulteration

  • 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 7 times across 7 separate inspections, most recently on September 29, 2026. For example: Equipment, non-food contact surfaces and linen are maintained, designed, constructed, installed and accessible for cleaning
