A HACCP plan is a written food safety program that systematically identifies biological, chemical, and physical hazards at each step of food production — then establishes controls to prevent them. The seven principles of HACCP were developed in the late 1950s by Pillsbury Company and NASA engineers, adopted by the FDA and USDA in the 1990s, and are now a legal requirement for most food manufacturers operating in the United States.
HACCP stands for Hazard Analysis and Critical Control Points. This guide walks through all seven principles, what each one requires, and how food manufacturers across different verticals apply them in practice.
The 7 principles of HACCP
Principle 1: Conduct a hazard analysis
Identify every biological, chemical, and physical hazard that could occur at each step of your production process — from incoming raw materials through finished product distribution. For each hazard, assess the likelihood of occurrence and the severity of the potential harm. Only hazards with meaningful risk proceed to the next step.
Common food hazards by type:
- Biological: Salmonella, E. coli, Listeria monocytogenes, Norovirus
- Chemical: Allergens, cleaning chemical residues, pesticide residues, mycotoxins
- Physical: Metal fragments, bone chips, glass, hard plastic pieces
Principle 2: Identify critical control points (CCPs)
A Critical Control Point (CCP) is a step in your process where a control measure can be applied and is essential to prevent or eliminate a food safety hazard, or reduce it to an acceptable level. Not every process step is a CCP — only those where control is essential and no later step will catch the hazard.
Examples of CCPs in food manufacturing:
- Cooking or pasteurization step — eliminates biological hazards
- Metal detection — removes physical hazards before packaging
- Refrigerated storage and receiving — controls bacterial growth
- Allergen separation point in production scheduling
Principle 3: Establish critical limits
For each CCP, define the measurable threshold that separates safe from unsafe. Critical limits must be based on scientific evidence — regulatory guidance, scientific literature, or validated studies. They are not targets or best-practice goals; they are the line below which a product is potentially unsafe.
Principle 4: Establish monitoring procedures
Define how each critical limit will be measured, who is responsible, and how frequently. Monitoring must be frequent enough to detect a loss of control in time to take corrective action before unsafe product reaches the next step. Temperature logs, pH measurements, and metal detector checks are common monitoring methods.
Principle 5: Establish corrective actions
Document exactly what happens when a critical limit is not met. Corrective actions have two components: (1) bring the process back under control, and (2) determine the disposition of any product that may have been affected while the CCP was out of control. Product disposition requires lot-level traceability — which lots were produced during the deviation window and where they went.
Principle 6: Establish verification procedures
Verification confirms that the HACCP system is working as designed. This includes reviewing monitoring records, conducting periodic microbial testing, calibrating monitoring equipment, and performing scheduled HACCP plan reviews. Verification is performed by someone other than the person doing the monitoring.
Principle 7: Establish recordkeeping and documentation
HACCP requires documented evidence that the system is operating. Required records include: the hazard analysis, the HACCP plan itself, CCP monitoring records, corrective action records, verification records, and calibration records. These records must be available for regulatory inspection and are central to traceability during a recall or audit.
Critical limits by food vertical
| Vertical | Common CCP | Critical limit |
|---|---|---|
| Meat processing | Cook step (whole muscle) | Internal temperature 145°F (63°C) for 15 seconds |
| Seafood | Cold chain at receiving | Product temperature 40°F (4°C) or below at receipt |
| Dairy | Pasteurization (HTST) | 161°F (72°C) for 15 seconds minimum |
| Beverage (acidified) | pH control | Finished product pH 4.6 or below |
| Produce (fresh-cut) | Antimicrobial wash | Free chlorine 50–200 ppm with pH 6.0–7.0 |
| Baked goods | Metal detection | No metal fragments above 2.0mm ferrous |
HACCP vs. related food safety programs
| Program | What it covers | Relationship to HACCP |
|---|---|---|
| HACCP | Hazard-specific controls at critical points in your process | The core system |
| GMP (Good Manufacturing Practices) | Facility sanitation, personnel hygiene, equipment maintenance | Prerequisite to HACCP — must be in place first |
| FSMA (Food Safety Modernization Act) | FDA framework for preventive controls, traceability, and supplier verification | FSMA requires a food safety plan that incorporates HACCP principles |
| SQF / BRC / GFSI schemes | Retailer-driven food safety certification | Build on HACCP; require documented HACCP plan as foundation |
How ERP software supports HACCP compliance
A HACCP plan is a written document, but compliance is an operational reality. The records required by Principle 7 — lot traceability, corrective action documentation, and audit trails — are only practical to maintain at scale with an integrated system.
inecta Food ERP, built on Microsoft Dynamics 365 Business Central, supports HACCP compliance through:
- Lot traceability (forward and backward) — trace any lot from raw material supplier through production to the finished product and customer shipment; essential for corrective actions when a CCP deviation occurs
- Allergen management at item and recipe level — tracks allergen codes (milk, eggs, nuts, gluten, shellfish, and others) linked to each inventory item, preventing undeclared allergen cross-contact
- FSMA compliance recordkeeping — captures FDA-required Critical Tracking Events and harvest type classifications for high-risk food commodities under FSMA Rule 204
- Production recordkeeping — documents consumption and output for each production order, creating the audit trail required for HACCP Principle 7
For food manufacturers, seafood processors, and meat processors, the connection between the HACCP plan and the ERP system is what makes the plan auditable — not just compliant on paper.
Frequently asked questions
What does HACCP stand for?
HACCP stands for Hazard Analysis and Critical Control Points. It is a systematic preventive approach to food safety that identifies physical, chemical, and biological hazards in production processes and establishes measurements to reduce the risks of those hazards to a safe level.
What are the 7 principles of HACCP?
The seven principles are: (1) Conduct a hazard analysis, (2) Identify critical control points, (3) Establish critical limits for each CCP, (4) Establish monitoring procedures, (5) Establish corrective actions, (6) Establish verification procedures, and (7) Establish recordkeeping and documentation.
Is HACCP required by law?
Yes, for most food manufacturers in the United States. The FDA requires HACCP for seafood (21 CFR Part 123), juice (21 CFR Part 120), and preventive controls under FSMA for all other food facilities. The USDA FSIS requires HACCP for meat and poultry processors (9 CFR Part 417). Dairy is regulated by state agencies, most of which require HACCP-aligned programs.
What is the difference between HACCP and FSMA?
HACCP is a food safety methodology — a set of seven principles for identifying and controlling hazards. FSMA (the Food Safety Modernization Act) is federal legislation passed in 2011 that requires food facilities to have written food safety plans incorporating HACCP principles, along with additional requirements for supplier verification, traceability, and preventive controls. FSMA expanded and modernized HACCP requirements rather than replacing them.
What is a critical control point (CCP)?
A Critical Control Point is a step in a food production process where a control measure can be applied to prevent, eliminate, or reduce a food safety hazard to an acceptable level, and where loss of control would result in unacceptable food safety risk. Common CCPs include cooking steps, pasteurization, metal detection, cold chain temperature control, and pH measurement in acidified products.
How often should a HACCP plan be reviewed?
HACCP plans must be reviewed whenever any change occurs that could affect the hazard analysis or alter a CCP, critical limit, monitoring procedure, corrective action, or verification procedure. At minimum, most regulatory frameworks and third-party audit schemes require an annual reassessment even if no changes have been made.
