aRegulatory action level is 50 ppm, but histamine levels may increase during processing. Therefore industry may want to set lower histamine critical limits at receiving.

3.6.6. Who Will Monitor?

Individuals assigned to monitor CCPs may include:

• Equipment operators.

• Maintenance personnel.

• Quality assurance personnel.

Once assigned, the individual responsible for monitoring a CCP must:

• Be adequately trained in the CCP monitoring techniques.

• Fully understand the importance of CCP monitoring.

• Have ready access (be close) to the monitoring activity.

• Accurately report each monitoring activity.

• Have the authority to take appropriate action as defined in the HACCP plan.

• Immediately report critical limit deviation.

It is important that the responsible individual report all unusual occurrences and deviations from critical limits immediately to make sure that process adjustments and corrective actions are made in a timely manner. This person should record and sign all monitoring results and occurrences associated with monitoring CCPs. Records and documents associated with monitoring CCPs should also be signed by one or more responsible reviewing officials of the company.
