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 April 27, 2026. For example:
4200 - Food-contact surfaces maintained, cleaned, sanitized
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 once on February 21, 2024. For example:
2120 - Proper cold holding temperatures; between 42 to 45 degrees Fahrenheit (F) (6 to 7 degrees Celsius (C))
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 February 21, 2024. For example:
1400 - Raw meats below and away from ready-to-eat food; species separated
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 These findings are administrative: the documentation was missing or out of date at the time of inspection.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 once on September 24, 2025. For example:
2600 - Compliance with valid permit; operating and risk control plans, and required written procedures
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 once on September 24, 2025. For example:
0100 - PIC present, demonstrates knowledge and performs duties to maintain AMC; certified manager on staff unless exempt
