The Codex Alimentarius Commission defines validation within a HACCP system as Oobtaining evidence that the elements of the HACCP plan are effective. In the Codex Alimentarius document, Hazard Analysis and Critical Control Point (HACCP) System and Guidelines for its Application (Annex to CAC/RCP1 - 1969, Rev. 3, 1997) there are two further mentions of validation:
Under the heading, Establish critical limits for each Critical Control Point, where it states: Critical limits must be specified and validated if possible for each Critical Control Point.
Under the heading, Establish verification procedures it states: Where possible, validation activities should include actions to confirm the efficiency of all elements of the HACCP plan.
