The Relationship Between HACCP, GMP, and GHP

In food safety management, three systems are closely connected: HACCP (Hazard Analysis and Critical Control Points), GMP (Good Manufacturing Practices), and GHP (Good Hygiene Practices).

Many businesses treat them as separate systems. In practice, they are not separate at all. HACCP depends on GMP and GHP in order to work properly. If the basic conditions inside the facility are weak, then even a well-written HACCP plan will fail in real operation.

The easiest way to understand their relationship is this:

GHP + GMP = the foundation
HACCP = the specific food safety control system built on that foundation

Without strong prerequisite programs, HACCP becomes only a document file instead of a working food safety system.

EU Regulation (EC) No 852/2004 requires food business operators to put in place hygiene measures appropriate to their activities and to implement procedures based on HACCP principles. This shows clearly that hygiene and operational controls come first, and HACCP is applied on top of them :contentReference[oaicite:0]{index=0}.

What is GHP?

Good Hygiene Practices (GHP) are the basic hygiene rules and daily practices that help prevent contamination of food.

They focus mainly on hygienic conditions in the food environment. GHP is concerned with cleanliness, sanitation, employee hygiene, and preventing contamination from the surroundings.

Typical GHP elements include:

personal hygiene
hand washing
cleaning and disinfection
pest control
waste handling
water quality
prevention of cross-contamination
hygienic storage conditions
basic temperature control

So GHP answers one important question:

How do we maintain a hygienic environment for safe food handling?

FAO explains that Good Hygiene Practices are essential prerequisites for the successful application of HACCP. In other words, HACCP is not meant to replace hygiene basics; it depends on them :contentReference[oaicite:1]{index=1}.

What is GMP?

Good Manufacturing Practices (GMP) deal more with how the business operates, how production is organized, and whether the facility and equipment are suitable for safe and consistent food production.

GMP is broader than simple hygiene. It covers the practical and technical conditions that allow the business to produce food in a controlled and repeatable way.

Typical GMP elements include:

building design and layout
equipment suitability
preventive maintenance
calibration of measuring devices
workflow and process design
raw material control
stock rotation
supplier approval
staff training
traceability
documentation and record keeping

GMP answers another key question:

How do we run the facility correctly and consistently so food can be produced under controlled conditions?

In many businesses, GHP and GMP overlap. For example, cleaning may be considered part of hygiene, while equipment design and maintenance are usually seen as GMP. The important point is not the label. The important point is that these measures are in place before the HACCP team starts identifying critical control points.

What is HACCP?

HACCP is a preventive system that identifies food safety hazards, evaluates where they may occur, and sets up controls to prevent, eliminate, or reduce them to acceptable levels.

It deals with hazards such as:

biological hazards
chemical hazards
physical hazards
in many modern systems, allergen-related hazards

HACCP then determines:

which hazards are significant
where control is necessary
whether a step is a critical control point (CCP)
what the critical limits are
how monitoring will be done
what corrective action is required
how verification and documentation will be maintained

So HACCP answers this question:

What are the specific food safety hazards in this process, and how will we control them?

FAO describes HACCP as a systematic preventive tool, while also emphasizing that prerequisite programs such as GHP are already expected to be functioning before HACCP is developed :contentReference[oaicite:2]{index=2}.

How HACCP, GMP, and GHP Work Together

The relationship between them is practical, not theoretical.

GHP and GMP control the general environment and operating conditions. HACCP focuses on the hazards that need specific control at defined points in the process.

For example, in a food production facility:

hand washing stations, cleaning schedules, and pest prevention belong mainly to GHP
equipment maintenance, calibrated thermometers, process flow, and storage systems belong mainly to GMP
cooking temperature monitoring for a high-risk product may be part of HACCP if that step is identified as a CCP

This means HACCP does not manage every food safety issue inside the business. It manages the specific significant hazards that remain after the general control measures are already working.

That is why many guidance documents describe GMP and GHP as prerequisite programs to HACCP :contentReference[oaicite:3]{index=3} .

Why HACCP Cannot Work Without GMP and GHP

This is where many businesses make mistakes. They prepare HACCP studies, define CCPs, and complete monitoring sheets, but basic hygiene and manufacturing discipline are weak.

If the building is poorly maintained, staff are not trained, pests are active, drains are dirty, cross-contamination is common, or cleaning is inconsistent, HACCP will not save the system.

In practice, if prerequisite programs are weak, the HACCP team usually ends up doing one of two wrong things:

they try to make HACCP cover too many general hygiene problems
they ignore real hazards because they assume the basics are under control when they are not

A common mistake is to identify too many CCPs because the business has not properly controlled the prerequisites. That makes the system heavy, confusing, and difficult to maintain. In most well-organized food operations, strong GHP and GMP reduce the number of true CCPs.

What most people don’t realize is that a simpler HACCP plan is often a sign of a stronger food safety system. When prerequisites are robust, HACCP can focus only on the steps that are truly critical.

Prerequisite Programs: The Bridge Between Them

The term prerequisite programs is important because it explains the real link between HACCP, GMP, and GHP.

Prerequisite programs are the basic conditions and activities necessary to maintain a hygienic environment throughout the food chain. Depending on the organization or standard, these may include:

GHP
GMP
sanitation procedures
supplier approval
maintenance
training
allergen management
traceability
pest management

FAO and other food safety guidance texts make it clear that these programs support HACCP and are not separate from the food safety system as a whole :contentReference[oaicite:5]{index=5} .

In other words:

GHP and GMP create the basic safe operating environment
prerequisite programs formalize these controls
HACCP analyzes the remaining significant hazards in the process

A Simple Example

Imagine a small food business producing cooked ready-to-eat meals.

The business has cleaning schedules, hand hygiene rules, protective clothing, pest control, waste management, approved suppliers, chilled storage, maintenance records, and staff training. These are mainly GHP and GMP controls.

Now the HACCP team examines the production flow. They may identify the cooking step as critical because it is the stage where dangerous microorganisms must be destroyed. They may also identify rapid cooling as essential to prevent bacterial growth.

So:

clean uniforms are not usually a CCP
hand washing is not usually a CCP
building maintenance is not usually a CCP
but cooking time/temperature may be a CCP

This example shows the difference clearly. General control measures belong to the prerequisite level. Specific hazard control belongs to HACCP.

In Regulatory and Practical Terms

Under modern food law and food safety systems, businesses are expected to implement hygiene and good practice first, then apply HACCP principles according to the nature and size of the operation :contentReference[oaicite:7]{index=7}.

In practice, inspectors and auditors do not only look at the HACCP chart. They also assess whether the prerequisite systems actually work: cleanliness, maintenance, staff behavior, pest evidence, storage practices, process discipline, and record integrity. EFET inspection guidance also reflects the need for systematic control and proper documentation in food business inspections :contentReference[oaicite:8]{index=8}.

In practice, a technician visiting a food business often finds that the HACCP file looks acceptable on paper, but the real weaknesses are elsewhere: damaged door sweeps, poor segregation of raw and ready-to-eat foods, missing cleaning verification, or no trend analysis for pest activity. These are not small details. They are signs that GMP and GHP are not supporting HACCP properly.

Final Thoughts

The relationship between HACCP, GMP, and GHP is not complicated once it is seen correctly.

GHP protects hygiene conditions.
GMP protects manufacturing discipline and operational consistency.
HACCP controls the specific significant hazards in the process.

They are not competing systems. They are layers of the same food safety structure.

If GHP and GMP are weak, HACCP will also be weak. If GHP and GMP are strong, HACCP becomes clearer, more focused, and much more effective.

That is the real relationship: HACCP depends on GMP and GHP, while GMP and GHP gain direction and food safety focus through HACCP.

Disclaimer

This article is for informational purposes only. Food safety (HACCP) and pest control requirements vary by country, authority, and type of food business. For legal compliance and audit readiness, always consult a qualified HACCP professional and a licensed pest control operator in your area.
All pest control measures must use approved products and be applied strictly according to the product label, as required by law in most jurisdictions (including the EU, UK, and USA). Improper use of pesticides, lack of documentation, or absence of a structured pest monitoring program may lead to non-compliance, fines, or business closure.
A compliant system must include documented procedures, monitoring records, corrective actions, and verification. Pest control is not optional—it is a core prerequisite program under HACCP and must be properly implemented, recorded, and reviewed.
