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 4 times across 3 separate inspections, most recently on May 26, 2026. 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 3 times across 3 separate inspections, most recently on May 26, 2026. For example:
1100 - Proper disposition of returned, unsafe, or contaminated food; proper date marking procedures for food at high risk for Listeria
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 2 times across 2 separate inspections, most recently on January 17, 2025. For example:
4100 - Warewashing facilities properly installed, maintained, used; sanitizer concentration; test strips available and used
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 2 times across 2 separate inspections, most recently on January 17, 2025. For example:
0600 - Adequate handwashing facilities
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 May 26, 2026. For example:
0100 - PIC present, demonstrates knowledge and performs duties to maintain AMC; certified manager on staff unless exempt
