ISO 22000

Monitoring systems are established for each critical control point so that the critical control point demonstrate control. The monitoring systems include scheduled measurements or observations relative to the critical limits.

A monitoring system must consist of relevant PROCEDURES, instructions and records that include:
- measurements or observations that provide results within an adequate time frame
- required monitoring devices
- applicable calibration methods
- monitoring frequency
- responsibility and authority related to monitoring and evaluation of monitoring results
- record requirements and methods

Monitoring methods and frequency are capable of determining when the critical limits have been exceeded in time for the product to be isolated before it is used or consumed.
