What is HACCP? An Introductory Guide
Hazard Analysis Critical Control Points (HACCP) is an internationally recognised management system that focuses on preventing and reducing food safety risks. By analysing and controlling biological, chemical, and physical hazards throughout the entire food production process, from procurement and handling of raw materials to the distribution and consumption of finished goods, HACCP ensures a high level of food safety management.
This systematic approach helps businesses identify potential hazards in their food production process and establish critical control points to prevent, eliminate, or reduce these hazards to acceptable levels. HACCP's primary goal is to protect consumers from unsafe food items and assure customers, the public, and regulatory agencies that the food safety program is well managed. Through continuous monitoring, verification, and effective implementation of HACCP plans, food businesses can successfully navigate the complexities of food safety while maintaining the highest industry standards.
Understanding HACCP
Hazard Analysis Critical Control Point (HACCP) is a systematic approach to identifying, evaluating, and controlling food safety hazards. It is an internationally recognised method focused on ensuring safe food production and consumption by managing the food industry's risks associated with biological, chemical, and physical hazards.
HACCP Principles
There are seven principles at the core of the HACCP system:
Conduct a hazard analysis: Identify potential food safety hazards that could occur during the production process.
Determine critical control points (CCPs): Identify points during the process where hazards can be prevented, eliminated, or reduced.
Establish critical limits: Set minimum and maximum boundaries for CCPs to ensure control of these points.
Monitor CCPs: Implement procedures to monitor critical control points and ensure they remain within the established limits.
Take corrective actions: Establish protocols for handling deviations from critical limits, including fixing the issue and preventing its recurrence.
Verification procedures: Regularly assess the HACCP system to ensure its effectiveness in controlling hazards.
Record-keeping and documentation: Maintain records of the HACCP plan, including hazard analysis, CCPs, monitoring records, and corrective actions source. Various vendors offer Food Safety software solutions that enable effective, accurate, and easy record-keeping for operators.
HACCP and Food Safety
The primary objective of HACCP is to prevent and reduce food safety hazards during raw material production, procurement and handling, manufacturing, distribution, and consumption. This method addresses food safety risks, ensuring customers, the public, and regulatory agencies are confident in a well-managed food safety program.
By implementing HACCP, food manufacturers can limit the potential for foodborne illnesses and reduce financial risks associated with product recalls. In turn, this helps maintain a company's reputation and fosters consumer trust in the safety of their products. Ultimately, HACCP is a crucial component of an effective food safety system, providing a comprehensive framework for managing food safety risks and ensuring that consumers enjoy safe and healthy food products.
Hazard Analysis and Identification
Types of Hazards
There are three main types of food safety hazards involved in the Hazard Analysis Critical Control Point (HACCP) system: biological, chemical, and physical hazards.
Biological hazards are caused by microorganisms such as bacteria, viruses, and parasites that can contaminate food and cause foodborne illnesses. Examples include Salmonella, E. coli, and Campylobacter.
Chemical hazards are substances that may be naturally present in food or introduced during food production, handling, or storage. Examples include pesticides, cleaning agents, and food additives.
Physical hazards are foreign objects that can potentially contaminate food products, causing injury or illness if ingested. Examples include glass shards, metal fragments, and plastic pieces.
Risk Assessment
The process of hazard analysis and identification involves assessing the probability and severity of each hazard in a food production environment. This involves identifying possible sources of hazards and evaluating the potential impact on food safety and quality. The main components of risk assessment in an HACCP system are hazard identification, likelihood of occurrence, and severity of consequences.
Hazard identification involves detecting possible sources of hazards in the food production process. This includes examining ingredients, storage conditions, packaging, critical process points, and relevant human factors that may affect food safety or quality.
Likelihood of occurrence is an estimate of the chance that a specific hazard will occur during a given stage in the food production process. Assessing the probability of a hazard occurrence helps to determine the appropriate control measures to implement.
Severity of consequences refers to the potential impact of a hazard on consumer health and safety. This includes understanding the potential outcome of consuming contaminated food products, such as the severity of illness or injury, as well as short-term and long-term effects.
In conclusion, hazard analysis and identification are crucial components of the HACCP system. By understanding the different types of food safety hazards and conducting a thorough risk assessment, food businesses can effectively control and minimise potential risks, ensuring safe and high-quality products for consumers.
Critical Control Points and Management
Identifying CCPs
Hazard Analysis Critical Control Points (HACCP) is a management system that focuses on ensuring food safety by addressing biological, chemical, and physical hazards. Critical Control Points (CCPs) are the main components of this system. Identifying CCPs involves determining the points, steps or procedures in a food process where control can be applied. As a result, food safety hazards can be prevented, eliminated or reduced to acceptable levels. Proper identification of CCPs is crucial for the effective implementation of the HACCP system.
Monitoring and Verification Procedures
Monitoring procedures play an essential role in the management of critical control points. These procedures involve regular observation and measurements at the CCPs, ensuring that they are under control and meet the established critical limits. A well-designed monitoring system helps to detect deviations from the critical limits and prompt timely corrective actions.
Verification procedures, on the other hand, ensure that the HACCP plan and its implementation are working effectively. This includes reviewing the monitoring records, conducting random checks of the CCPs, and evaluating the overall performance of the HACCP system. Verification procedures help to confirm that the management system is providing the desired level of food safety.
Critical Limits and Corrective Actions
Critical limits are the maximum or minimum values for a specific parameter, such as temperature or pH, that must be met to control a potential hazard. These limits are essential in the HACCP system as they provide measurable and observable criteria to ensure food safety.
Corrective actions are the steps taken when monitoring procedures detect deviations from the established critical limits. These actions should be predetermined and documented in the HACCP plan, including the responsible person for carrying out the necessary measures. Corrective actions may involve adjusting the process, discarding affected products or conducting additional verification procedures to ensure that the critical control points are back under control.
In summary, the HACCP system relies on the proper identification and management of critical control points, monitoring and verification procedures, and the establishment of critical limits and corrective actions. These components work together to ensure that potential food safety hazards are addressed effectively, resulting in a safer and more reliable food supply.
Implementing HACCP in Food Production
Flow Diagram and Preliminary Steps
Implementing HACCP in food production involves a series of preliminary steps that pave the way for creating an effective HACCP plan. The first step is to assemble a multidisciplinary HACCP team, comprising professionals with knowledge and expertise in different aspects of food production, processing, and safety.
Next, the HACCP team must develop a detailed flow diagram of the entire food production process, from the procurement of raw materials to the distribution of the finished product. This flow diagram serves as a visual representation of the process and helps in identifying potential food safety hazards at different stages. The team should also describe the intended use of the product, its target consumers, and any potential risks associated with its consumption.
Once the flow diagram is completed, the HACCP team conducts a thorough hazard analysis of each step in the process to determine the critical control points (CCPs) where control measures must be applied to prevent, eliminate, or reduce hazards to acceptable levels.
HACCP Plan and Documentation
A key component of implementing HACCP in food production is the development of a comprehensive HACCP plan. This plan outlines the identified hazards, the associated CCPs, and the control measures to be applied. Additionally, the plan should include:
Monitoring procedures for each CCP
Corrective actions to be taken when monitoring indicates a deviation from established critical limits
Verification procedures to confirm that the HACCP system is working effectively
Recordkeeping and documentation systems to demonstrate compliance with the HACCP plan
The documentation associated with the HACCP plan is crucial, as it serves as evidence that the necessary measures for maintaining food safety are being followed. It also provides a framework for periodic audits and evaluations of the food production process to ensure its continued effectiveness.
Training and Maintenance
Equally important to the implementation of HACCP in food production is ensuring that all personnel involved in food handling receive adequate HACCP training. This training equips employees with the knowledge and skills required to correctly implement and adhere to the HACCP plan, enabling them to identify potential food safety risks, execute control measures, and monitor the success of the plan.
Lastly, the HACCP system must be regularly maintained to ensure ongoing effectiveness. This involves routine inspections, process audits, and reviews of the HACCP plan and documentation to verify that the system remains compliant with applicable food safety regulations and guidelines. Moreover, any changes or modifications to the food production process should be swiftly incorporated into the HACCP plan to maintain its suitability and relevance.
Regulations, Certification and Compliances
Food Safety Legislations
The Hazard Analysis Critical Control Point (HACCP) system is a globally recognised approach to managing food safety risks. It is used by food establishments, including manufacturers, processors and distributors, to ensure the safety of their products. In the United States, the FDA and the USDA are responsible for enforcing food safety regulations, including HACCP requirements. The Food Safety Modernization Act (FSMA) further strengthens these regulations, focusing on proactive prevention of food safety issues.
HACCP Certification Agencies
To demonstrate compliance with HACCP principles and regulatory requirements, many food businesses seek HACCP certification. Certification agencies, such as NQA and the International HACCP Alliance, evaluate and certify food establishments based on their adherence to HACCP principles. These seven principles include conducting hazard analysis, identifying critical control points, establishing critical limits, implementing monitoring procedures, developing corrective actions, verifying that the system works effectively, and maintaining proper records.
Continual Improvement
HACCP is not a stagnant process; it requires continual improvement to ensure that food safety risks are effectively mitigated. This means regular reassessment of hazards, updating of procedures, and employee training to ensure that the food safety management system remains effective. The principle of verification in the HACCP system encompasses auditing and reviewing the system, as well as ensuring that it conforms to regulatory requirements and industry best practices.
Traceability
An essential aspect of HACCP is traceability, enabling food businesses to effectively trace and track their products throughout the entire supply chain. This ensures that any potential hazards or issues can be quickly identified and addressed, thus minimising the risk of foodborne illness or contamination. Traceability systems must be robust, ensuring that information is accurate and readily available. Compliance with traceability standards and requirements is crucial for maintaining food safety and the integrity of the HACCP system. Operations should consider software solutions build for food traceability to enable effective, accurate, and easily available data.

HACCP and Related Systems
HACCP (Hazard Analysis Critical Control Point) is a systematic approach to identify, evaluate, and control food safety hazards, including biological, chemical, and physical hazards in the food production process 1. This section will discuss the various systems and concepts related to HACCP, such as prerequisite programmes, ISO 22000, FSSC 22000, HARPC, and preventive controls.
Prerequisite Programmes
Prerequisite programmes are fundamental practices and conditions needed for food safety at every stage of the process, from raw material production to distribution and consumption 2. These programmes ensure that hygiene and other operational conditions are in place for effective HACCP implementation. Some examples of prerequisite programmes include:
Good Manufacturing Practices (GMPs)
Sanitation Standard Operating Procedures (SSOPs)
Pest control measures
ISO 22000 and FSSC 22000
ISO 22000 is an internationally recognised food safety management system standard that incorporates the principles of HACCP along with other requirements, such as prerequisite programmes, management commitment, and continuous improvement 3. This standard is applicable to organisations of any size and can be used by both food and non-food industries to ensure safe food production.
FSSC 22000 (Food Safety System Certification) is a scheme based on ISO 22000, complemented with additional requirements for specific industries 3. It is recognised by the Global Food Safety Initiative (GFSI) and is designed to provide a robust and harmonised food safety management system for the entire food supply chain.
HARPC and Preventive Controls
Hazard Analysis and Risk-based Preventive Controls (HARPC) is a food safety approach that expands on traditional HACCP concepts 2. HARPC requires organisations to conduct a comprehensive risk assessment, taking into account both food safety hazards and potential intentional adulteration events. The main difference between HARPC and HACCP lies in the mandatory preventive controls for identified risks.
Preventive controls are measures that address identified hazards and ensure the safety of the food produced 1 2. These controls may include process controls, food allergen controls, sanitation controls, supply chain controls, and a recall plan. Implementation of preventive controls in food production ensures that potential food safety hazards are properly managed and mitigated.
In conclusion, HACCP and its related systems provide a comprehensive framework for managing food safety throughout the food production process. By understanding and implementing these systems, organisations can ensure safe food products for consumers while adhering to international standards and regulations.
