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.
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 once on March 15, 2025. For example:
PERSONAL CLEANLINESS AND HAIR RESTRAINTS
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 once on March 15, 2025. For example:
PROPER REHEATING PROCEDURES FOR HOT HOLDING
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 once on March 15, 2025. For example:
FOOD PROPERLY STORED; FOOD STORAGE CONTAINERS IDENTIFIED
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 once on January 9, 2024. For example:
TOXIC SUBSTANCES PROPERLY IDENTIFIED, STORED, USED
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 January 9, 2024. For example:
NO RODENTS, INSECTS, BIRDS, OR ANIMALS
