What constitutes monitoring for a CCP, and what might be a typical method?

• A. Regular measurement or observation to ensure a CCP stays within its critical limits
• B. Post-production customer surveys
• C. Visual inspection of packaging only
• D. Annual audits

Answer: (A)

Monitoring a CCP means regularly measuring or observing a process parameter to ensure the CCP stays within its defined critical limits. It’s about collecting data in a timely and repeatable way so you can tell, during production, whether the process is in control or if an action is needed.

A typical method is using a calibrated device to record the parameter at set intervals or continuously. For example, you might monitor the internal temperature of food during cooking with a thermometer or data logger, or check the cooling temperature/time profile at scheduled points. If the reading approaches or crosses a critical limit, you follow the predetermined corrective actions to bring the process back under control. This monitoring should be documented so trends can be reviewed and improvements made.

Other activities like post-production customer surveys look at consumer response rather than the process control itself. Visual inspection of packaging alone isn’t sufficient to confirm that a CCP is under control, because many CCPs depend on factors like temperature, time, or pH that visual checks alone can’t reliably verify. Annual audits are verification activities done less frequently and don’t provide the ongoing, real-time data needed to ensure continuous control of the CCP.
