Verification

Verification is the process of checking that a food-safety system is being followed and is working as intended. In a HACCP-based programme, verification confirms that monitoring, corrective actions and supporting procedures are implemented and effective. It is distinct from validation, which establishes that a control measure is capable of achieving the intended food-safety outcome.

Common verification methods

• Record review: checking cooking, cooling, receiving and sanitation logs for completeness and deviations.
• Direct observation: watching staff perform handwashing, temperature checks and allergen controls.
• Calibration: confirming that thermometers and other measuring devices are accurate.
• Inspection: reviewing equipment, premises, storage and sanitation conditions.
• Testing: using suitable product or environmental tests where required by the food-safety plan.

Verification in a restaurant

Verification frequency should be based on risk, process complexity, previous results and regulatory requirements. It may be performed by a supervisor, manager or another qualified person who can assess the procedure objectively. Findings and corrective actions should be documented.

Example: a manager reviews cooling records, checks that thermometers are calibrated and observes whether staff follow the approved cooling procedure.

Verification versus monitoring and validation

Monitoring checks a control during operation. Validation provides scientific or technical evidence that the control can achieve the intended safety result. Verification confirms that the system is implemented and remains effective.

Chef’s note: verification is not simply signing a checklist. The reviewer must assess actual results, investigate deviations and confirm that corrective actions have been completed.
