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.

• 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 3 times across 3 separate inspections, most recently on September 16, 2025. For example: 3400 - Wiping cloths properly used, stored; sanitizer concentration

• 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 across 2 separate inspections, most recently on March 22, 2023. For example: 3000 - Proper thawing methods used

• 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 March 22, 2023. For example: 3200 - Insects, rodents, animals not present; entrance controlled

• 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 September 28, 2015. For example: 0600 - Adequate handwashing facilities

• 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 These findings are administrative: the documentation was missing or out of date at the time of inspection.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 November 5, 2024. For example: 2600 - Compliance with valid permit; operating and risk control plans, and required written procedures
