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 3 times across 2 separate inspections, most recently on October 1, 2026. For example:
Mechanical dishwashing: Wash / rinse water clean, correct water temperature and timing cycles, sanitizer at correct concentration (not a NSF/ANSI Standard 3 Dishwasher).
