Which statement about critical limits is NOT accurate?

Which statement about critical limits is NOT accurate?

• A. It is the maximum or minimum value to which a parameter must be controlled
• B. It must be achievable
• C. It is often driven by practicality and experience
• D. It is a guess without data

Answer: (D)

Critical limits are the specific, measurable criteria that separate acceptable from unacceptable operation at a CCP. They define the maximum or minimum value to which a parameter must be controlled, such as a certain temperature, time, pH, or moisture level, to prevent or reduce a food safety hazard. These limits must be achievable with the actual process and equipment, meaning they can be monitored and enforced in real time or with validated methods. In practice, setting limits often involves practical considerations and the experience of those running the process, but they are ultimately grounded in data, validation, and risk assessment. They are not arbitrary guesses. If a limit is exceeded, corrective actions are triggered to bring the process back under control.
