How often should sanitation verification be performed?

• A. Randomly when someone remembers.
• B. At planned intervals or after changes, with documented evidence of effectiveness.
• C. Only once at the start of the shift.
• D. Every hour regardless of changes.

Answer: (B)

Verification of sanitation is a planned, ongoing check to confirm that cleaning actually removes soil and residues. The best practice is to perform it at planned intervals or after changes, with documented evidence of effectiveness. This approach keeps sanitation control consistent over time, rather than relying on memory or guesswork, and it ensures you catch issues even if conditions change.

Regular, scheduled verification provides a record you can review, trend over time, and use for audits or corrective actions. Verifying after changes—such as new equipment, new products, or different soils—ensures the cleaning remains effective under the new conditions. Doing it randomly, only at the start of a shift, or every hour regardless of changes either lacks a structured plan or wastes resources and can miss issues that arise in between planned checks.
