Hazard Analysis Control Point: Definition

What Is a Hazard Analysis Control Point?

A hazard analysis control point is a specific location, activity, or procedure in a production process where a hazard can be managed, minimized, or eliminated as part of a structured food safety plan. The concept originates from the HACCP (Hazard Analysis and Critical Control Points) methodology, which was developed by NASA and the Pillsbury Company in the 1960s and later formalized by the Codex Alimentarius Commission.

Control points differ from Critical Control Points in their risk significance. At a control point, existing controls reduce the hazard to an acceptable level, but failure at that step would not immediately result in an unsafe product reaching consumers. At a Critical Control Point, failure without correction would directly produce an unacceptable food safety risk.

Understanding the distinction matters because HACCP documentation, monitoring intensity, and corrective action requirements are far more rigorous for CCPs than for standard control points. Misclassifying a step can either overburden operations with unnecessary monitoring or leave genuine hazards under-controlled.

Control Point vs. Critical Control Point

The HACCP decision tree is the standard tool for determining whether a step is a control point or a Critical Control Point. The classification depends on four questions related to the hazard, the control measure in place, and whether a subsequent step can eliminate the risk.

How Control Points Are Identified in a HACCP System

Identifying control points begins with the hazard analysis, which is the first of the seven HACCP principles. The HACCP team constructs a flow diagram of every step in the production process, from raw material receipt through storage and distribution.

For each step, the team asks three core questions:

• Is a hazard present at this step? (biological, chemical, or physical)
• What is the likelihood and severity of the hazard if not controlled?
• Does a control measure exist at this step?

Steps where a hazard is present and a control measure exists are provisionally classified as control points. The HACCP decision tree then determines whether each CP rises to the level of a CCP. If a step can be controlled through a prerequisite program and a subsequent step provides an additional safety barrier, it remains a CP. If no subsequent step can eliminate the hazard and failure would result in an unsafe product, the step becomes a CCP.

The output is a table listing every process step, the hazard type, the control measure, and the classification (CP or CCP). This table becomes the foundation of the written HACCP plan.

Types of Hazards Addressed in Hazard Analysis

The hazard analysis phase of HACCP evaluates three primary hazard categories. Each requires different control measures and monitoring approaches.

Biological Hazards

Biological hazards include pathogenic bacteria (Salmonella, Listeria monocytogenes, E. coli O157:H7, Campylobacter), viruses (norovirus, hepatitis A), and parasites (Cryptosporidium, Toxoplasma). These are the most common cause of foodborne illness outbreaks. Control measures include thermal processing, pH control, water activity reduction, and employee hygiene. Steps managing biological hazards often qualify as CCPs when they are the only barrier against a life-threatening pathogen.

Chemical Hazards

Chemical hazards include pesticide and veterinary drug residues, food allergens, cleaning and sanitizing chemical residues, environmental contaminants (heavy metals, PCBs), and naturally occurring toxins (mycotoxins, marine biotoxins). Allergen control programs, supplier specification verification, and equipment flushing procedures are typical control measures. Many allergen management steps are classified as control points managed through prerequisite programs rather than as CCPs, though this depends on the facility's specific risk assessment.

Physical Hazards

Physical hazards include foreign material that could cause injury: glass fragments, metal shavings, bone, plastic pieces, stones, and personal items. Metal detectors and X-ray systems used to detect and reject contaminated product are typically designated as CCPs because they are the final barrier before the product ships. Upstream equipment maintenance checks and glass and brittle plastic control programs are control points that reduce the introduction of foreign material earlier in the process.

Role of Control Points in a HACCP Plan

A HACCP plan is structured around the seven HACCP principles. Control points inform Principle 1 (conduct a hazard analysis) and Principle 2 (identify CCPs). They also shape the prerequisite programs that support the entire system.

Well-designed prerequisite programs address the majority of hazards through control points, keeping the number of CCPs manageable. Industry guidance recommends that facilities limit CCPs to genuine food safety essentials. Facilities with too many CCPs often struggle with monitoring burden and documentation overload, which increases the risk of non-compliance.

Control points managed through prerequisites include:

• Sanitation and cleaning programs (equipment and facility)
• Pest control
• Personnel hygiene and training
• Allergen segregation and changeover procedures
• Supplier approval and incoming material verification
• Temperature control during storage and distribution (where not a CCP)
• Calibration of non-critical measurement instruments

For teams tracking compliance with FSMA, BRCGS, SQF, or ISO 22000, documentation of all control points and prerequisite programs is a mandatory audit requirement. Gaps in this documentation are among the most common findings in third-party food safety audits.

Monitoring and Documentation at Control Points

While CCPs require continuous or frequent recorded monitoring with defined critical limits, control points are typically monitored through Good Manufacturing Practices and periodic verification activities. The monitoring approach for each control point is proportional to the severity and likelihood of the hazard it controls.

Typical monitoring activities for control points include:

• Pre-operational sanitation inspections before production starts
• Allergen swab testing after changeovers between allergen-containing and allergen-free products
• Supplier certificate of analysis review for incoming raw materials
• Employee hygiene observations during production runs
• Equipment condition checks as part of a scheduled maintenance checklist

Documentation best practices for control points include naming the responsible person, specifying the monitoring method and frequency, defining acceptable and unacceptable outcomes, and recording the corrective action taken when a deviation occurs. Teams using a CMMS can assign recurring inspection tasks to specific process steps, attach documentation directly to equipment records, and generate audit-ready reports without manual compilation.

Standard operating procedures are the primary vehicle for documenting control point requirements. Each Standard Operating Procedure (SOP) should specify the hazard being controlled, the control measure, the expected outcome, and the corrective action if the outcome is not achieved.

Examples Across Food, Pharmaceutical, and Manufacturing Industries

The hazard analysis control point concept is most developed in food safety, but the same logic applies in pharmaceutical manufacturing and general industrial settings where product quality or worker safety depends on controlling hazards at specific process steps.

Food and Beverage

In a ready-to-eat meat processing facility, control points include:

• Receiving dock temperature check for chilled raw materials (biological hazard control)
• Allergen declaration verification on supplier packaging (chemical hazard control)
• Employee glove and handwashing compliance check before handling exposed product (biological hazard control)
• Clean-in-place (CIP) verification after processing runs (biological hazard control)

The CCP in the same facility would be the listericidal cooking step, where a critical limit of internal product temperature is monitored continuously and recorded at defined intervals.

Pharmaceutical Manufacturing

Pharmaceutical manufacturing uses a hazard analysis approach aligned with ICH Q9 (Quality Risk Management) and GMP guidelines. Control points in a tablet manufacturing line include:

• Raw material identity verification against certificate of analysis
• Granulation blend uniformity testing
• Environmental monitoring of classified cleanroom areas

Critical control points include sterilization validation steps and endotoxin testing before aseptic fill, where failure would render the batch unsafe for patient use.

General Manufacturing

In industrial food-contact component manufacturing, hazard analysis identifies control points such as:

• Lubricant application steps where food-grade lubricants must be used (chemical hazard control)
• Surface finish inspection for components that contact consumables (physical hazard control)
• Scheduled equipment inspection to prevent metal shavings from contaminating production areas

Equipment maintenance quality directly affects hazard control. Worn seals, degraded conveyor components, and inadequately lubricated machinery are recurring sources of physical and chemical contamination at control points that are otherwise well-designed on paper. Linking maintenance schedules to HACCP control points in a CMMS ensures the physical condition of equipment supports the safety plan at all times.

Hazard Analysis Control Points and Regulatory Frameworks

Several major regulatory and certification frameworks reference hazard analysis control points directly or through equivalent concepts.

Frequently Asked Questions

The Bottom Line

HACCP is the food safety framework that transformed how the industry thinks about contamination risk. By requiring a systematic analysis of where hazards can occur and establishing control measures at those specific points, it replaces inspection-based quality assurance with prevention-based process control — a shift that applies equally to biological, chemical, and physical hazards.

For maintenance teams in food processing facilities, HACCP has direct operational implications. Equipment that comes into contact with food product must be maintained to a standard that prevents contamination: food-grade lubricants, allergen segregation, and surface integrity are maintenance concerns, not just food safety concerns. Maintenance work orders that specify food-safety-compliant materials and procedures, and CMMS records that document compliance, are part of the audit trail that HACCP certification requires.
