What is a critical limit in a HACCP plan?

• A. A maximum or minimum value to which a hazard must be controlled at a CCP.
• B. A recommended cooking time.
• C. A target cost per batch.
• D. A supplier certification requirement.

Answer: (A)

In HACCP, a critical limit is the maximum or minimum value to which a hazard must be controlled at a CCP to ensure safety. This value is a specific, measurable threshold that, when reached or exceeded, indicates the process is under control and the hazard is being prevented or reduced to an acceptable level. For example, cooking poultry to 165°F (74°C) for a minimum amount of time is a typical critical limit because staying at or above that temperature for the required time reliably reduces harmful pathogens. The critical limit is chosen based on food science data and is tied directly to the hazard analysis and chosen control measures.

This differs from a recommended cooking time, which is a guideline rather than a strict, measurable threshold used to judge whether a batch is safe. It also isn’t a target cost per batch, which relates to budgeting rather than safety. And it isn’t a supplier certification requirement, which belongs to prerequisite programs and supplier verification, not to the control of a specific hazard at a critical point in the process.
