How often should monitoring records be reviewed for verification?

• A. Only annually
• B. Every hour
• C. At predetermined intervals by trained personnel (frequency defined in HACCP plan)
• D. Monthly random sampling

Answer: (C)

In HACCP, verifying that monitoring is effective means reviewing the records at planned, predefined intervals by personnel trained for this task. The frequency is set in the HACCP plan to match the process risk and monitoring methods, ensuring consistent checks and timely detection of any drift or deviation. This approach keeps verification systematic and credible, with trained staff able to interpret results and determine if actions are needed. Options that rely on annual, hourly, or random monthly reviews don’t align with the planned, risk-based schedule and can miss trends or shifts in control.
