Inspection summary

Thai Diner has been inspected 24 times by City of Hamilton Public Health Services since January 12, 2022. The most recent inspection, on August 5, 2026, found no infractions.

7 of 24 inspections on record found no infractions at all. In the past 12 months there were 5 inspections with 14 infractions recorded. The higher-risk findings here relate to: Protecting food from contamination, Cleaning and sanitizing and Food temperature control.

The number of infractions per inspection has stayed roughly the same over time.

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 21 times across 13 separate inspections, most recently on April 20, 2026. For example: Floors, walls, and ceilings clean and in good repair and maintained in a sanitary manner

  • 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 11 times across 9 separate inspections, most recently on November 27, 2025. For example: Equipment, utensils, multi-service articles and all food contact surfaces are properly constructed

  • 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 9 times across 7 separate inspections, most recently on April 15, 2026. For example: Mechanical dishwashing: Wash / rinse water clean, water temperature, timing cycles, sanitizer

  • 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 4 times across 4 separate inspections, most recently on July 30, 2025. For example: Food premise is protected against the entry and harbouring of pests

  • 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 November 27, 2025. For example: Hand washing basin with supplies of soap and paper towels in dispensers
