Inspection summary

Em Oi Vietnamese has been inspected 16 times by City of Hamilton Public Health Services since August 31, 2022. The most recent inspection, on October 2, 2026, recorded 4 infractions.

2 of 16 inspections on record found no infractions at all. In the past 12 months there were 4 inspections with 11 infractions recorded. The higher-risk findings here relate to: Food temperature control, Protecting food from contamination and Cleaning and sanitizing.

Recent inspections have recorded more infractions than earlier ones, so it is worth reading the latest reports closely.

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 13 times across 11 separate inspections, most recently on July 28, 2026. For example: Mechanical dishwashing: Wash / rinse water clean, water temperature, timing cycles, sanitizer

  • 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 10 times across 6 separate inspections, most recently on October 2, 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 6 times across 6 separate inspections, most recently on July 28, 2026. For example: Equipment, utensils, multi-service articles and all food contact surfaces are properly constructed

  • Chemicals and toxic substancesHigher risk

    Cleaning products, sanitizers and pesticides must be labelled and stored away from food and food-contact surfaces. Inspectors flag chemicals that could end up in food, as well as pest treatments applied without proper supervision.

    Recorded 4 times across 4 separate inspections, most recently on September 2, 2025. For example: Toxic or poisonous substances required for maintenance in food premises are stored and handled as prescribed in the regulation

  • 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 2 times across 2 separate inspections, most recently on October 2, 2026. For example: Food premise is protected against the entry and harbouring of pests
