What is HACCP? Definition, principles and implementation at a glance

Employees on the assembly line check compliance with HACCP

HACCP is mandatory for all food businesses – from small craft businesses and restaurants to industrial production facilities. The basis is... EU Regulation (EC) No 852/2004, which requires a functioning hygiene management system and a risk-based control system. The HACCP system identifies potential hazards in food, assesses them, and establishes effective control measures.

Our content is provided by certified HACCP specialists, auditors and hygiene officers Created. This ensures you receive technically accurate, practice-oriented information of the highest quality.

Table of contents

Definition & meaning of HACCP

HACCP stands for Hazard Analysis and Critical Control Points.
It is a systematic procedure for identifying, assessing and controlling potential hazards.
throughout the entire food production and processing process.

Objectives of the HACCP system

  • Recognize dangers early 
  • Controlling identified dangers
  • Minimize risks for consumers
  • Ensuring a safe end product
  • Standardize and document processes
  • Meet regulatory requirements

What exactly does HACCP encompass?

  • Hazard analysis (biological, chemical, physical, radiological)
  • Evaluation of the risks
  • Establishment of CCPs (Critical Control Points) and other control measures
  • Definition of Limit values
  • Setting of Surveillance and Control measures, as well as corrective actions
  • Verification & Validation
  • documentation

HACCP vs. PRPs (Operational Prerequisites)

A common misconception: HACCP does not replace basic operational hygiene.
PRPs (Prerequisite Programs) include basic hygiene measures such as:

Employee washes hands to comply with HACCP.
PRPs are a prerequisite for HACCP to function at all.
The symbol of a paragraph is held up to the sun.

Legal basis

A HACCP system is not a voluntary measure – it is mandatory. legally required.

Relevant legal provisions

EU Regulation (EC) No 852/2004

The central legal framework for all food businesses. The regulation requires, among other things:

  • Self-monitoring systems
  • Measures according to HACCP principles
  • Documentation & Evidence
  • Staff training

Guideline C 355/2022 – Implementation of HACCP

The EU guideline (C 355/2022) specifies how HACCP should be implemented in practice.
It contains examples of CCPs, oPRPs and PRPs, typical errors and industry-specific advice.

What documents does the authority require?

  • HACCP concept
  • Hazard analysis
  • CCP evidence and records
  • Temperature controls
  • Cleaning and disinfection schedules
  • Pest monitoring
  • Training certificates
  • Verification and validation evidence

The 7 HACCP principles

  1. Conduct a hazard analysis
    In this first step, all biological, chemical, physical and radiological hazards that may occur along the entire process – from goods receipt through production to shipping – are identified.
    Hazard analysis is the heart of the system: it determines which risks must be controlled.
    and where checkpoints make sense.
  2. CCPs and other control measures (oPRPs) determine
    A CCP (Critical Control Point) is a critical control point where a failure
    would directly lead to a health hazard. Typical CCPs include, for example, heating processes,
    Refrigerated storage or metal detection. The selection is based on a structured evaluation matrix.
    or decision trees.
  3. Setting limit values
    For each CCP and each other control measure, clear, measurable limits must be defined – e.g.
    a minimum core temperature, a maximum storage temperature, or permissible residual values.
    Limit values must be scientifically sound and often originate from legal requirements.,
    Standards or validation studies.
  4. Set up a monitoring system
    This section defines how compliance with the limit values is monitored – for example, by
    Temperature measurements, visual inspections, or automatic sensors.
    The intervals, responsibilities, and recording method are also important.
    A CCP or control measure without effective monitoring is not a functioning CCP / not a functioning measure.
  5. Define corrective actions
    What happens if a limit value is exceeded?
    Corrective measures ensure that products with potential risks are withdrawn from the market.
    and at the same time the process error is corrected.
    Examples: reheating, sorting, blocking an entire production batch,
    Checking the device or adjusting the process.
  6. Perform verification
    Verification ensures that the HACCP system is effective and functions as intended.
    This is done through internal audits, trend analyses, laboratory tests, or the review of
    Monitoring data. Also the validation – that is, proof that processes are actually safe –
    is part of this principle.
  7. Create documentation
    An HACCP system is only legally compliant and auditable if all steps are traceable.
    This must be documented. This includes process descriptions, hazard analyses, CCP protocols,
    Verification reports and training certificates. This documentation serves as proof for authorities.
    and facilitates the ongoing improvement of the system.

PRPs – the indispensable foundation


PRPs (Prerequisite Programs) They form the hygienic foundation of the entire food safety system.
They address general conditions and measures that are necessary to create a safe environment for food production.

Examples of PRPs

Difference to CCPs:
PRPs generally prevent hygiene risks in the operation, while CCPs control critical points in the process where errors can directly lead to health hazards.

Step-by-step instructions

  1. HACCP team appointed
  2. Describe the products and define their intended use
  3. Create a process flowchart
  4. Conduct a hazard analysis for each step
  5. CCPs and other control measures determine
  6. Define limit values and tolerances
  7. Define monitoring measures
  8. Define corrective actions for deviations
  9. Perform verification and, if necessary, validation.
  10. Create documentation and train employees

It is essential that you regularly check and update your system. Set intervals that suit your company and your industry.

Typical mistakes

  • Incomplete or missing PRPs
  • Incomplete or missing oPRPs
  • Too many or incorrectly defined CCPs
  • No clear definition of limit values
  • Inadequate monitoring and documentation
  • No or infrequent verification
  • Employees are not receiving sufficient training.

Practical examples of CCPs

  • Core temperature during heating
  • Pasteurization with a defined temperature-time combination
  • Metal detector in final inspection

Who is HACCP relevant for?

HACCP affects almost all businesses that produce, process, transport or distribute food.
This includes both traditional food producers and catering establishments such as Restaurants,
Caterers and food trucks. Catering establishments are also obligated, for example Canteens,
School and daycare catering or company catering facilities. Also Bakeries and Confectioneries,
Food retailers and large chain stores must demonstrate a functioning HACCP system.


Furthermore, the obligation applies to logistics companies, which with Refrigerated or frozen transport work,
for Packaging and Packaging manufacturer as well as for producers of dietary supplements.
In the health and social care sector – for example in Clinics, nursing homes or rehabilitation centers – is HACCP as well
relevant for start-ups that are new to the food industry.
In short: Wherever food comes into contact with people, HACCP is a central component of the
legally required hygiene management.

Frequently asked questions about training for food companies

CCP (Critical Control Point):
A CCP is a point, step, or procedure at which control is essential to prevent a foodborne illness or other adverse event. to prevent, eliminate or reduce to an acceptable level significant health risk. If control at a CCP fails, there is a high risk to food safety.

OPRP (Operational Prerequisite Program / Operational PRP):
An OPRP is a key risk control measure, which was deemed necessary as part of the hazard analysis, but is not classified as a CCP. This measure is operationally monitored to ensure that conditions are met to prevent or control contamination (e.g. sieves, metal detectors, water monitoring).

There is no rigid template that would be identical for all businesses.
The legal requirements arise primarily from EU Regulation (EC) No. 852/2004 and from guidelines such as C 355/2022 and the Codex Alimentarius.
Each company must develop an individual, risk-based system.

A review and update must be carried out at least once a year.
Additionally, whenever processes, products, premises or legal requirements change.

The costs depend on company size, product portfolio and existing hygiene management.
They range roughly from a few thousand euros for small businesses to significantly higher amounts in complex production environments.
