Required validation frequency includes which option?

• A. Before the food safety plan is implemented
• B. Within the first 90 calendar days of production
• C. Within reasonable timeframe with written justification
• D. When a change in control measures could impact efficacy

Answer: (C)

Validation frequency for preventive controls is set by risk and process variability, with the schedule documented and justified in writing. This means you validate within a reasonable timeframe and provide written justification for the timing, allowing flexibility based on how complex or risky the process is and how stable its performance has been. The requirement isn’t a rigid calendar date (like before implementation or a fixed 90 days); nor is validation only about changes in control measures. Changes can prompt revalidation, but the general approach is to validate within a reasonable timeframe with written justification.
