ISO 22000 - (Section 8 - Validation, verification and improvement of the food safety management system)

8.5. Improvement

8.5.1 Continual improvement

Top management shall ensure that the organization continually improves the effectiveness of the food safety management system through the use of communication (see 5.6), management review (see 5.8), internal audit (see 8.4.1), evaluation of individual verification results (see 8.4.2), analysis of results of verification activities (see 8.4.3), validation of control measure combinations (see 8.2), corrective actions (see 7.10.2) and food safety management system updating (see 8.5.2).


NOTE ISO 9001 addresses continual improvement of the effectiveness of quality management systems. ISO 9004 provides guidance on continual improvement of the effectiveness and efficiency of quality management systems beyond what is addressed in ISO 9001.


8.5.2 Updating the food safety management system

Top management shall ensure that the food safety management system is continually updated.


In order to achieve this, the food safety team shall evaluate the food safety management system at planned intervals. The team shall then consider whether it is necessary to review the hazard analysis (see 7.4), the established operational PRP(s) (see 7.5) and the HACCP plan (see 7.6.1).


The evaluation and updating activities shall be based on

  1. input from communication, external as well as internal, as stated in 5.6,
  2. input from other information concerning the suitability, adequacy and effectiveness of the food safety management system,
  3. output from the analysis of results of verification activities (see 8.4.3), and
  4. output from management review (see 5.8.3).

System updating activities shall be recorded and reported, in an appropriate manner, as input to the management review (see 5.8.2).
