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.
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 6 times across 5 separate inspections, most recently on January 27, 2026. For example:
Food is protected from potential contamination (i.e. food covered, labelled, off floor, stored on racks, sneeze guard, physical hazards).
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 5 separate inspections, most recently on July 30, 2026. For example:
Food is held at 4°C (40°F) or less.
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 July 30, 2026. For example:
There is adequate protection against the entrance of insects, vermin, rodents, dust and fumes into the food premise.
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 once on January 27, 2026. For example:
Food contact surfaces washed / rinsed / sanitized after each use and following any operations when contamination may have occurred.
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 3 times across 3 separate inspections, most recently on February 4, 2026. For example:
Equipment, non-food contact surfaces and linen are maintained, designed, constructed, installed and accessible for cleaning.
