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.
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 11 times across 8 separate inspections, most recently on August 24, 2023. For example:
1600 - Proper cooling procedure
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 5 times across 5 separate inspections, most recently on October 1, 2021. For example:
3400 - Wiping cloths properly used, stored; sanitizer concentration
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 3 times across 2 separate inspections, most recently on October 1, 2021. For example:
0400 - Hands washed as required
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 These findings are administrative: the documentation was missing or out of date at the time of inspection.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 4 times across 4 separate inspections, most recently on September 24, 2025. For example:
2600 - Compliance with valid permit; operating and risk control plans, and required written procedures
