What type of noncompliance occurs if an employee does not monitor at the frequency specified in the HACCP plan?

The type of noncompliance that occurs when an employee fails to monitor at the specified frequency in the Hazard Analysis Critical Control Point (HACCP) plan is related to monitoring. Monitoring is a critical component of the HACCP system, as it involves the continuous observation or measurement of parameters to ensure that the established critical limits are being met.

When monitoring is not performed as per the schedule outlined in the HACCP plan, it can lead to situations where potential hazards are not identified in a timely manner, ultimately compromising food safety. This lapse signifies a direct deviation from the HACCP plan and indicates that the system may not be functioning as intended.

In the context of the other choices, while verification, recordkeeping, and corrective actions are all important aspects of the HACCP system, they pertain to other specific processes. Verification involves confirming that the HACCP plan is effective and working properly, recordkeeping focuses on maintaining accurate documentation of monitoring results and other relevant data, and corrective actions are the steps taken when monitoring indicates a deviation from critical limits. However, none of these directly address the failure to monitor at the required frequency, making monitoring the correct focus for the noncompliance described in the question.
