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 6 times across 6 separate inspections, most recently on February 24, 2026. 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 5 times across 4 separate inspections, most recently on February 2, 2023. For example:
1600 - Proper cooling procedure
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 4 separate inspections, most recently on February 21, 2024. For example:
3300 - Potential food contamination prevented during delivery, preparation, storage, display
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 3 separate inspections, most recently on December 17, 2019. For example:
3500 - Employee cleanliness and hygiene
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 4 times across 4 separate inspections, most recently on September 19, 2022. For example:
4300 - Nonfood-contact surfaces maintained and clean
