How do verification and validation differ in HACCP?

• A. Validation proves the HACCP plan is capable of controlling hazards before operation; verification confirms the plan is being properly implemented and remains effective during operation
• B. Verification is ongoing during operation; validation is pre-operation
• C. They are the same
• D. Validation is only for marketing

Answer: (A)

In HACCP, validation and verification are two separate activities that serve different roles in ensuring food safety. Validation is about proving, before operation, that the plan can effectively control the identified hazards. It relies on evidence from design, science, and data—such as process design, time–temperature calculations, and pilot testing—to show that the control measures and CCPs, if implemented as intended, will achieve the required safety outcomes.

Verification, on the other hand, is an ongoing process during operation. It confirms that the HACCP plan is being properly implemented and continues to work as intended. This includes monitoring CCPs, checking calibration and maintenance records, reviewing verification activities, and making adjustments if monitoring shows deviations or if there are changes to ingredients, processes, or products. If significant changes occur, revalidation may be needed to confirm continued control.

So the best framing is that validation proves the plan is capable of controlling hazards before operation, while verification confirms the plan is being properly implemented and remains effective during operation. The other statements either merge timeframes or misstate purposes (for example, suggesting validation is only for marketing).
