What Is a Critical Control Point (CCP)? Definition, Examples, and How to Identify One

A critical control point (CCP) is a step in a food production process where a control measure can be applied that is essential to prevent, eliminate, or reduce a food safety hazard to an acceptable level. That is the definition used by both the FDA's HACCP Principles and Application Guidelines and the Codex Alimentarius General Principles of Food Hygiene (CXC 1-1969), which contains the internationally recognized HACCP annex. Not every processing step is a CCP. Identifying critical control points correctly is the second of the seven HACCP principles, and it's one of the most commonly misapplied parts of a HACCP plan.

What Makes a Step a Critical Control Point?

A step qualifies as a CCP only when two things are both true: a hazard that matters is reasonably likely to occur at or before that step, and no later step in the process will reliably eliminate or reduce that hazard to an acceptable level. If a later step - like a cook step, or a customer-side control - would catch the same hazard, the earlier step is usually a control point (CP) or a prerequisite program, not a CCP.

Most HACCP training programs apply a version of the CCP decision-tree logic built into the Codex HACCP annex: is there a control measure at this step; is the step specifically designed to eliminate or reduce the hazard to an acceptable level; could contamination occur or increase beyond an acceptable level at or after this step; and will a subsequent step eliminate the hazard or reduce it to an acceptable level. A 'yes/no' path through these questions, applied consistently for each hazard at each process step, is what most HACCP plans document as the CCP determination.

CCP vs. Control Point vs. Prerequisite Program

A control point (CP) is any step where a hazard could be controlled, but where losing control wouldn't lead to an unacceptable food safety risk on its own - a metal detector on a line that also has a downstream detector, for example, or a labeling check backed up by a second verification. A prerequisite program (like sanitation, pest control, or supplier approval under a documented food safety program) creates the conditions that let a HACCP plan work, but it isn't usually where the plan places its CCPs. Confusing a CP with a CCP is one of the most common reasons auditors flag a HACCP plan - either too many CCPs (which makes the plan unmanageable) or too few (which leaves a real hazard unmanaged).

Common Critical Control Point Examples in Food Manufacturing

The exact CCPs in a plan depend on the product, process, and hazard analysis, but the following categories show up repeatedly:

• Cooking or pasteurization - where time and temperature are the only reliable way to achieve a required lethality for pathogens like Salmonella or Listeria monocytogenes.
• Cooling - when cooling rate is the sole control preventing spore-forming organisms like Clostridium botulinum or Clostridium perfringens from germinating and growing.
• Metal detection or X-ray inspection - when it's the last point in the process capable of catching a physical hazard before the product ships.
• pH or water activity adjustment - in shelf-stable or acidified products, where formulation is the control that prevents pathogen growth.
• Formulation of preservatives or curing agents - where a specific concentration is what prevents toxin formation.

Some programs also treat a final allergen or label verification step as a CCP, though many QA programs instead manage it as an operational prerequisite program with its own verification - this varies by facility and should be documented as part of the hazard analysis rather than assumed.

Critical Limits, Monitoring, and Corrective Actions at a CCP

Once a CCP is identified, HACCP Principles 3 through 5 require a measurable critical limit (a specific temperature, time, pH, or concentration), a monitoring procedure that checks the actual limit during production, and a corrective action plan for what happens when a limit is exceeded. The FDA's HACCP guidelines outline all seven principles together, since CCP identification only works as part of the full system - a CCP without a validated critical limit and a monitoring record isn't a functioning control, just a label on a step.

How CCPs Fit Into a Complete HACCP Plan

CCP identification is one part of a seven-principle system that starts with hazard analysis and ends with verification and recordkeeping.

FAQ

What is the difference between a CCP and a CP?

A CCP (critical control point) is a step where losing control creates an unacceptable food safety risk with no later step to catch it. A CP (control point) is a step where a hazard is managed, but a failure there wouldn't, on its own, result in an unsafe product because another step or program backs it up.

How many CCPs should a HACCP plan have?

There's no fixed number - it depends entirely on the product and process. A well-built plan typically has a small number of true CCPs (often 1-5 per process), not a long list. A plan with too many CCPs is often a sign that control points and prerequisite programs were mislabeled as CCPs.

Who decides what counts as a CCP?

The HACCP team responsible for the plan makes that determination, based on the hazard analysis and a documented decision process. Auditors from SQF, BRCGS, or FSSC 22000 will expect to see the reasoning recorded, not just the final list.

What happens if a critical limit is exceeded at a CCP?

The HACCP plan's corrective action procedure takes over: affected product is identified and held, the cause is investigated, the process is brought back under control, and the event is documented. Product produced while the limit was out of control generally cannot be released without an evaluation of its safety.

Is metal detection always a CCP?

Not necessarily. It's a CCP when it's the last opportunity to catch a physical hazard before the product reaches the consumer. If there's a later inspection or detection step that would also catch the same hazard, metal detection may instead be documented as a control point.

A HACCP plan is only as strong as its CCP determinations. See how IONI's HACCP Builder identifies CCPs, sets critical limits, and keeps monitoring records tied to your actual process.
