HACCP key terms

HACCP · Get comfortable with the vocabulary.

HACCP

A systematic, science-based food safety management approach that identifies hazards, sets control points and limits, monitors them, and verifies that the system is working.

Related: Hazard analysis, Critical control point (CCP), Verification
Prerequisite program

Basic environmental and operational conditions, such as sanitation, pest control, and employee hygiene, that must be in place before a HACCP system can effectively control food safety hazards.

Related: Good Manufacturing Practices (GMP), Sanitation Standard Operating Procedures (SSOP), HACCP plan
Good Manufacturing Practices (GMP)

Regulations and practices covering facilities, equipment, personnel, and processes to ensure food is produced under sanitary conditions and is safe and suitable for its intended use.

Related: Prerequisite program, Sanitation Standard Operating Procedures (SSOP), Sanitation
Sanitation Standard Operating Procedures (SSOP)

Written procedures describing the specific cleaning and sanitizing tasks, frequencies, chemicals, and monitoring needed to maintain sanitary conditions in food production areas and on equipment.

Food safety hazard

Any biological, chemical, or physical agent in food that can cause illness or injury, or any condition that could lead to such contamination.

Related: Biological hazard, Chemical hazard, Physical hazard
Biological hazard

Living organisms or their toxins-such as bacteria, viruses, parasites, or molds-that can contaminate food and cause human illness when consumed.

Related: Pathogen, Food safety hazard, Control measure
Chemical hazard

Harmful chemical substances that may enter food, including cleaning agents, pesticides, toxins, drug residues, and allergens, and that can cause illness or injury at unsafe levels.

Related: Allergen, Food safety hazard, Control measure
Physical hazard

Foreign objects such as glass, metal, plastic, stones, or bone fragments that can cause injury or illness if present in food at unacceptable levels.

Related: Food safety hazard, Control measure, Monitoring
Allergen

A normally harmless protein that triggers an immune reaction in sensitive people; in food safety it must be controlled through labeling, segregation, and cleaning to prevent undeclared exposure.

Related: Chemical hazard, Cross-contamination, Sanitation Standard Operating Procedures (SSOP)
Cross-contamination

Transfer of harmful microorganisms or allergens from contaminated sources-such as raw food, equipment, hands, or surfaces-to ready-to-eat food or clean areas.

Related: Allergen, Ready-to-eat food, Sanitation Standard Operating Procedures (SSOP)
HACCP plan

A written document prepared for a specific food product or process that lists the hazards, critical control points, critical limits, monitoring, corrective actions, verification, and records required.

Related: HACCP team, Hazard analysis, Critical control point (CCP)
HACCP team

A multidisciplinary group with knowledge of the product, process, and food safety hazards that develops, implements, and maintains the HACCP plan.

Related: HACCP plan, Hazard analysis, Verification
Flow diagram

A step-by-step schematic of a food process showing all inputs, processing steps, storage, and outputs; it is verified on site and used to identify where hazards may occur.

Hazard analysis

The process of identifying potential biological, chemical, and physical hazards at each step, assessing their likelihood and severity, and determining which are significant enough to require control.

Related: Risk assessment, Significant hazard, Control measure
Risk assessment

A structured evaluation of the likelihood and severity of a food safety hazard, used to decide whether the hazard is significant and how much control is needed.

Related: Hazard analysis, Likelihood and severity, Significant hazard
Likelihood and severity

The two dimensions used to judge a hazard's risk: how probable contamination or illness is, and how serious the resulting harm would be.

Related: Risk assessment, Significant hazard
Significant hazard

A hazard that is reasonably likely to occur at an unacceptable level and to cause illness or injury unless a control measure is applied.

Related: Hazard analysis, Control measure, Critical control point (CCP)
Control measure

Any action, process, or technology-such as cooking, refrigeration, metal detection, or sanitation-that prevents, eliminates, or reduces a significant food safety hazard to an acceptable level.

Related: Critical control point (CCP), Critical limit, Significant hazard
Decision tree

A structured series of questions used to determine whether a control measure at a process step qualifies as a critical control point.

Related: Critical control point (CCP), Hazard analysis
Critical control point (CCP)

A specific point, step, or procedure in the food process where a control measure is essential and can be applied to prevent, eliminate, or reduce a significant hazard to an acceptable level.

Related: Critical limit, Control measure, Monitoring
Critical limit

A measurable maximum or minimum value that must be met at a CCP to ensure the control measure effectively prevents, eliminates, or reduces the identified hazard; exceeding it constitutes a deviation.

Related: Critical control point (CCP), Monitoring, Deviation
Operating limit

A tighter value than the critical limit that a processor uses to reduce risk and allow early action before the critical limit is exceeded.

Related: Critical limit, Deviation, Corrective action
Control point

A step where a hazard can be controlled, but loss of control does not necessarily create an unacceptable food safety risk, so it is not designated a CCP.

Related: Critical control point (CCP), Control measure
Monitoring

Planned, scheduled measurement or observation of a CCP and its critical limits to confirm the process remains under control and to detect deviations promptly.

Related: Critical limit, Deviation, Corrective action
Deviation

A failure to meet a critical limit at a CCP, indicating that the process may have produced unsafe food and requiring corrective action and product evaluation.

Related: Critical limit, Corrective action, Monitoring
Corrective action

The documented steps taken when monitoring detects a deviation, including correcting the process, determining product disposition, and preventing recurrence of the problem.

Related: Deviation, Product disposition, Monitoring
Product disposition

The decision about what to do with food produced during a deviation-such as holding, testing, reworking, diverting, or destroying it-based on a safety evaluation.

Related: Corrective action, Deviation, Hold
Hold

A status that keeps suspect product out of commerce until its safety is evaluated and a disposition decision is made.

Related: Product disposition, Corrective action
Verification

Ongoing activities, other than monitoring, that confirm the HACCP plan is working as intended, such as record reviews, calibration checks, audits, and product testing.

Related: Validation, Recordkeeping, Monitoring
Validation

Scientific and technical evidence gathered before and during operation to show that control measures and critical limits are capable of controlling the identified hazard.

Related: Verification, Critical limit, Control measure
Recordkeeping

The creation and retention of documents such as monitoring logs, corrective action reports, calibration records, and verification results that demonstrate the HACCP system is operating correctly.

Related: Verification, Monitoring, Corrective action
HACCP reassessment

A planned or triggered review of the entire HACCP plan to determine whether it remains valid after changes in product, process, equipment, or scientific information.

Related: Verification, Validation, HACCP plan
Calibration

Comparing a measuring instrument-such as a thermometer or pH meter-against a known standard and adjusting it to ensure monitoring readings are accurate.

Related: Monitoring, Verification, Critical limit
Pathogen

A microorganism, such as Salmonella, Listeria, or E. coli O157:H7, that can cause illness when present in food at sufficient levels.

Related: Biological hazard, Significant hazard
Ready-to-eat food

Food that is consumed without further cooking or processing to eliminate hazards, so it must be protected from contamination throughout production, storage, and handling.

Related: Cross-contamination, Allergen, Prerequisite program
Sanitation

The process of cleaning surfaces to remove soil and then treating them with heat or chemicals to reduce microorganisms to levels that do not compromise food safety.
