How can you use HACCP principles to identify food safety hazards?

HACCP is an operational framework that focuses on ensuring food safety by thoroughly examining and managing potential biological, chemical, physical and allergen hazards throughout the entire food production process. This includes the stages of raw material sourcing, procurement, handling, manufacturing, distribution, and consumption of the final product.

in addition, depending on the type of industry the food hazards can vary in the HACCP plan. nutritional hazard could also be part of the HACCP plan.

In Simple words Hazard Analysis: Identify biological, chemical, and physical hazards. CCPs: Cooking, cooling, and packaging ensure microbial control. Critical Limits: Set min cooking temp; establish max packaging time. Monitoring CCPs: Use temp probes; inspect packaging integrity. Corrective Actions: Adjust time/temperature; halt production for defects. Verification: Regularly review records, conduct testing, inspect equipment. Record-Keeping: Maintain logs of cooking temps, packaging checks, and corrective actions. Personnel Training: Provide concise training on procedures, critical limits, hygiene, and recognizing/responding to deviations.

Hazard Analysis Critical Control Points (HACCP) is a globally recognized, systematic and science-based approach to food safety that addresses biological, chemical and physical hazards throughout the food chain from primary production (raw material) to (finished product) final consumption. A food safety program, however, does not just stop with HACCP. To be effective, prerequisite programs such as pest control, traceability & recall, hygiene and sanitation must be developed and implemented.

HACCP is certainly a science based approach to finding food safety hazards and then controlling them in any food industry manufacturing unit. One hazard which many people and companies don’t pay that much attention is Nutritional hazard. This means overdosing of a certain nutrient (due to a manufacturing fault or else) may cause an allergic reaction/ medical condition to a consumer. An effective HACCP plan combined with HAZOP (at the design stage) may be a very effective method for controlling these hazards in first place.

Indeed, the initial step in implementing Hazard Analysis and Critical Control Points (HACCP) principles is to conduct a thorough hazard analysis. This involves systematically evaluating each stage of the food production process to identify potential biological, chemical, or physical hazards that could compromise food safety. The goal is to comprehensively understand and document the risks associated with the entire production process, setting the foundation for the subsequent establishment of critical control points (CCPs) and the development of effective control measures to ensure the safety of the final food product.

Start with creating the cross functional food safety team. This team then will do the Hazard Analysis of the entire process from receiving to despatch. Various available tools can be used to carry out the Hazard Analysis.

Fail to plan is planning to fail. The pre-requisites for HACCP provide all necessary information to conduct a hazard analysis. This includes specifications (raw material & final product), intended use, target population, facility, possible cross-flows, raw material risk assessment, identification of utilities (e.g. water, steam, food grade gasses, compressed air), equipment used, processes (process flow diagramme), outputs (waste), rework and returns, as well as the environment. Only then can the experienced food safety team perform the hazard identification. It is important to remember that the severity of a hazard will remain the same, whilst the likelihood may differ. An open mind without pre-conceived ideas is needed.

To conduct a hazard analysis, identify potential hazards in each step of food production. Assess biological, chemical, and physical risks. Determine control measures, establish critical control points, monitor, and document the process for ongoing safety assurance.

Hazard analysis is the first step of any food safety plan. This step allows you to identify potential hazards in every step of your production process and analyze each one for its potential risk and occurrence. The process of analyzing hazards involves an organized set of steps that break down the entire food production process.

A critical control point (CCP) is a critical point, critical step or procedure at which control can be applied and a food safety hazard can be mitigated, prevented, eliminated or reduced to acceptable levels. For Evaporated Tin Milk production the following are examples some of its CCP's 1.) Seaming 2.) Sterilisation 3.) Pasteurization 4.) Fermentation 5.) Filtration etc. For Coffee and Cocoa production (CCP's) 1.) Roasting 2.) Fermentation 3.) Metal detector system etc.

Critical Control Point or CCP as it is known is the last point of any control measure post which if the critical point is breached the product is affected sometimes to a limit of rejection. You can use risk probability number to determine a CCP.

Pinpoint critical control points by scrutinizing production stages for potential hazards, focusing on interventions that significantly mitigate risks. Evaluate factors like frequency, severity, and efficacy to determine strategic control measures ensuring food safety.

In the process of CCP determination, one must identify and describe hazards, detail control measures, and highlight specific processing steps where these measures are enforced.

Following hazard analysis, the second step in applying Hazard Analysis and Critical Control Points (HACCP) principles is to identify critical control points (CCPs). CCPs are specific stages in the food production process where control measures can be applied to prevent, eliminate, or reduce hazards to acceptable levels. These points are pivotal for ensuring food safety. By pinpointing CCPs, the focus shifts towards establishing critical limits, monitoring procedures, and implementing corrective actions, forming a structured framework that systematically manages and safeguards against potential risks identified during the hazard analysis.

(HACCP), involves defining specific criteria at critical control points (CCPs). These limits serve as boundaries to control hazards effectively. Critical limits should be based on scientific data, regulatory standards, or industry guidelines. Collaborate with relevant experts to set measurable and achievable limits. Clearly define the parameters that indicate control over potential hazards. The established critical limits must be precise, ensuring that monitoring can effectively detect any deviations and trigger corrective actions. Regular monitoring and verification processes are essential to maintaining the integrity of these critical limits and ensuring ongoing food safety.

Establish critical limits by defining specific criteria or values at critical control points. Base these limits on scientific data, regulations, or industry standards, ensuring they serve as clear benchmarks to effectively control and monitor potential hazards in the food production process.

Recordar que los límites críticos además de ser medirlos y alcanzables (verificandose en la frecuencia que se considere apropiada) debe ser un parámetro capaz de medirse en forma continua, es decir, nuestro proceso puede controlar esta variable en el 100% de los casos, por ejemplo la temperatura de pasteurizacion de un equipo térmico.

Critical limits can often be found in the documentation accompanying government regulations. For instance, in the FDA food code, it provides the water activity and pH levels that distinguish a shelf stable product from one that requires time and temperature control.

Establishing critical limits in food safety involves setting specific criteria to control identified hazards at critical control points. These limits define the acceptable boundaries for factors like temperature, time, pH, and other critical parameters. They serve as benchmarks to ensure that preventive measures effectively manage and mitigate potential risks during food production processes.

The purpose of this monitoring is to confirm that the critical limits are being continuously achieved and to detect any loss of control to enable effective corrective action to be taken. Procedures for monitoring should be established and all relevant staff should be trained in the appropriate methods as well as in the appropriate recording of results.

Monitor CCPs with a vigilant blend of technological tools and sensory checks. Employ real-time data analysis and sensory expertise to ensure precision, creating a dynamic system for constant oversight and immediate response to deviations.

The fourth step in applying Hazard Analysis and Critical Control Points (HACCP) principles is monitoring the critical control points (CCPs). Regularly observe and measure parameters at CCPs to ensure they stay within established critical limits. Implement a systematic and documented monitoring process to promptly identify any deviations, enabling timely corrective actions. Consistent monitoring is essential to maintaining control over potential hazards and upholding the safety of the food production process.

Measuring ,observations,analysing the critical limits at every stage of monitoring and carefully recording the results ,ensuring that the materials used for measurement are properly calibrated and checked at every point of measurements to be very sure of the measurement

As far as I know, HACCP is a systematic preventive approach to ensuring food safety. The principles of HACCP involve seven key steps: 1) Conducting a Hazard Analysis, 2) Identifying Critical Control Points (CCPs), 3) Establishing Critical Limits, 4) Monitoring CCPs, 5) Establishing Corrective Actions, 6) Verification, and 7) Documentation and Record Keeping. By systematically applying these HACCP principles, food industry professionals can identify and control potential hazards at every stage of the food production process.

In the fifth step of applying Hazard Analysis and Critical Control Points (HACCP) principles, the HACCP plan undergoes verification and validation processes. Verification ensures that the plan is effective and being implemented correctly. Validation involves confirming that the plan is scientifically sound and capable of controlling identified hazards. These processes may include reviewing records, conducting periodic reassessments, and seeking expert input. By regularly verifying and validating the HACCP plan, the organization ensures ongoing effectiveness and adherence to food safety standards. This step is integral to maintaining a robust and reliable food safety management system.

Currently, scientific data is abundant and available at anyone's fingertips as input in your validation method and justification. An esential part of HACCP plan validation is the ability to provide evidence that the critical limits for the CCP can be achieved successfully in your facility, for your specific product, and manufactured with your equipment. Triggers for re-validation need to be identified. Continual verification will provide the evidence that the specific hazard identified is controlled through the HACCP plan. Include validation and verification for your OPRP if your FSMS is based on ISO 22000.

HACCP requires team collaboration involving a multidisciplinary team in the HACCP development process, including individuals with expertise in food safety, production, quality control, and relevant technical areas. You should apply Continuous improvement. HACCP is an evolving system. Regularly review and update the plan based on changes in processes, equipment, regulations, or identified hazards.

Hazard analysis has to be dymanic and updated after every new lessons learnt from different inputs like, food safety incidents, audits, monitoring systems, changes in process or technology, new scientific data etc. Also, need to consider human factors like personnel behaviour and practicality when deciding the monitoring mechanism and verification activities.

L'étude HACCP doit être mise à jour régulièrement, notamment dans le cadre de développement produits. Plus l'équipe est sollicitée, plus elle gagne en efficacité et plus le process est solide ! La communication est clef, ainsi que la pluridisciplinarité.

One last thing I want to add as “food” for thought. How can we add critical thinking and critical assessment in everyday day production line. Safety/HACCP is one hand but sometimes fast decisions prevents any possible hazard !
