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 3 times across 3 separate inspections, most recently on June 12, 2026. For example: Food protected from potential contamination and/or adulteration

• 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 2 times on January 7, 2026. For example: Potentially hazardous food is held at 4°C (40°F) or lower

• 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 June 12, 2026. For example: Adequate protection against the entrance of insects, vermin, and rodents

• 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 3 times across 3 separate inspections, most recently on June 12, 2026. For example: Separate hand washing basin provided for food handlers

• 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 once on October 8, 2025. For example: Equipment, non-food contact surfaces and linen are maintained, designed, constructed, installed and accessible for cleaning
