Chapter 8 / 1
Definition: Monitoring: A planned sequence of observations or measurements to assess whether a CCP is under control and to produce an accurate record to demonstrate that critical limits have been met

Chapter 8 / 2
Purpose of Monitoring: • To ensure that a critical limit is met, • To provide documentation that critical limits have been met, • To identify when there is loss of control (a deviation occurs at a CCP)

Elements of Monitoring • • • •
What will be monitored? How will monitoring be performed? What is the frequency of monitoring? Who will conduct the monitoring?

Chapter 8 / 4
What will be monitored? A measurement or observation to assess if the CCP is operating within the critical limit
Seafood HACCP Alliance for Training and Education
Chapter 8 / 5
How will monitoring be performed? • Measurements (quantitative critical limits) or observations (qualitative critical limits). • Needs to be real-time and accurate.

Chapter 8 / 6
What is the frequency of monitoring? • Monitoring frequency should be sufficient to ensure that the critical limit is met. • Monitoring frequency can be non-continuous or continuous.

Chapter 8 / 8
Those responsible for monitoring a CCP should: • • • • •
Be trained in the CCP monitoring techniques. Fully understand the importance of CCP monitoring. Have ready access to the monitoring activity. Accurately report each monitoring activity. Immediately report critical limit deviations
