What these findings mean
Health authorities word their findings differently, so we group them by what they mean for the people in care. Higher-risk findings are the ones that could directly make someone sick, and they matter more here because young children, older adults and people who are unwell are more vulnerable to infection.
Food temperature controlHigher risk
Inspectors check that anything that has to be kept at a set temperature, such as chilled or hot food, or equipment like sterilizers, stays in its safe range and that accurate thermometers are on hand. With food, temperature problems are one of the most common causes of food poisoning.
Recorded 4 times across 2 separate inspections, most recently on October 22, 2025. For example:
Mechanical dishwashing: wash, rinse, sanitize and water temperature
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, supplies 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 July 4, 2025. For example:
Adequate protection against the entrance of pests
Food safety training and certificationLower risk
Many jurisdictions require a trained or certified person on site, such as a certified food handler. These findings mean the training record or the trained person was missing at the time. They do not by themselves mean anything was handled unsafely.
Recorded once on January 9, 2026. For example:
Food handler demonstrates proper food hygiene practices to prevent contamination
Other findingsLower risk
Findings that do not fit the categories above, such as follow-ups that confirm an earlier violation was corrected, or requirements specific to this type of facility.
Recorded 2 times across 2 separate inspections, most recently on October 24, 2025. For example:
Food from an inspected source
