Which option describes when validation should occur?

Which option describes when validation should occur?

• A. Validation must occur only at startup
• B. Validation occurs when a change in control measures could impact efficacy
• C. Validation is not required after implementation
• D. Validation is performed annually regardless of changes

Answer: (B)

Validation is about proving that a preventive control will reliably control the hazard in practice. It’s not a one-time event at startup; it must be revisited whenever a change could affect how well the control works. If you modify control measures—such as adjusting process parameters, changing equipment, altering formulations, or introducing new ingredients—those changes could impact the control’s effectiveness, so revalidation is necessary to confirm continued efficacy. Without changes, ongoing monitoring and verification keep the process in check, but they don’t replace the need to revalidate when efficacy could be affected. Therefore, the correct description is that validation should occur when a change in control measures could impact efficacy.
