Critical Limit

Absolute tolerance value which must be met for each control measure at a CCP. A value outside the Critical Limit indicates a deviation and potentially unsafe product. Usually a numerical value, this outlines the minimum acceptability of which the hazard can be controlled. Every CCP must have a critical limit. For example, the limit of detection for a metal detector, and therefore the critical limit, may be 2mm Ferrous, 2.5mm Non-ferrous and 4mm Stainless Steel to reflect the test pieces used to check the viability of the metal detector.
