HACCP Notes

Introduction to HACCP

The Initial Doubt

That split-second hesitation before eating something, wondering if it's safe, is a universal experience. HACCP (Hazard Analysis and Critical Control Points) is designed to eliminate that doubt through a robust food safety system.

What is HACCP?

HACCP is a proactive approach to food safety, focusing on preventing hazards rather than just reacting to problems. It's a systematic way of thinking about food safety that emphasizes building safety into the entire food supply chain, from farm to consumer.

Proactive vs. Reactive

HACCP is proactive. It aims to prevent issues before they occur, as opposed to reacting after something has gone wrong. It spans the entire food supply chain, from the farm all the way to the consumer.

Origin of HACCP

HACCP began in the 1960s through a collaboration between Pillsbury and NASA. NASA needed a fail-safe system to ensure astronauts' food was completely safe from biological, chemical, and physical hazards.
They adapted Failure Mode and Effect Analysis (FMEA), an engineering concept used for spacecraft systems, to food production. This involved identifying potential failures and their effects to ensure near total certainty of food safety for astronauts.

Shift in Thinking

HACCP represents a shift from accepting some risk to demanding almost zero risk in food safety. It introduced a preventative, almost guaranteed safety mindset.

Critical Control Points

Adoption and Goals

HACCP gained public recognition in the 1970s for its effectiveness in preventing foodborne diseases. The World Health Organization (WHO) recognized it as the most effective method available, and it has since become an international standard used by organizations like the FAO and Codex Alimentarius.

The core idea of HACCP is prevention, aiming to stop hazards from occurring in the first place. This is a shift from end-product testing, which is likened to "checking the parachute after you've jumped."

Traditional vs. HACCP

Traditional food safety measures included:

• Training for food handlers.

• Inspections of premises.

• Microbiological testing of finished batches.

However, these measures were often fragmented and reactive. HACCP provides a unified, proactive approach, designing the entire process to be safe, placing responsibility on the producer and meeting consumer expectations for safe, reliable food.

HACCP Mechanics

HACCP involves a thorough look at the entire food production flow, analyzing everything from farm to fork to identify potential hazards at each stage. Hazards include biological, chemical, and physical risks.

The first step is a detailed analysis, asking:

• What is the specific hazard?

• Where could it happen?

• How could it get into the food?

• When is it most likely to occur?

• Who is responsible for controlling it?

Critical Control Points (CCPs)

Critical Control Points (CCPs) are specific steps where control can be applied to prevent, eliminate, or reduce a hazard to a safe level. Not every step is a CCP, but only those crucial for safety.

Critical Limits

For each CCP, establish critical limits, which are clear, measurable boundaries that define safe versus unsafe conditions. An example is the minimum internal temperature chicken needs to reach to kill salmonella.

Need A System

Monitoring

Implement a system to regularly check each CCP. This involves taking measurements and making observations to ensure critical limits are not crossed. Monitoring frequency is key to catching problems quickly.

Corrective Actions

For every CCP, have a pre-planned corrective action ready to implement if monitoring shows a deviation. This action must get the process back under control and address any food produced while the process was out of control. This might include holding, reprocessing, or discarding the product.

Documentation

Maintain records of everything, including:

• Hazard analysis

• CCPs determination

• Critical limits

• Monitoring results

• Deviations

• Corrective actions taken

Verification

Regularly check the entire system through verification, audits, reviews, and testing to ensure the plan is working as intended and remains relevant.

Hazard Categories

• Biological Hazards: Bacteria (e.g., Salmonella, E. coli, Listeria), viruses, and parasites. Temperature control is vital, keeping hot foods hot and cold foods cold. The danger zone is roughly $4$ to $60$ degrees Celsius (about $40$ to $140$ Fahrenheit). Keep foods below $-18$ Celsius for freezing. Prevent cross-contamination and ensure proper sanitation.

• Chemical Hazards: Natural toxins, intentionally added chemicals (e.g., nitrates in cured meats, pesticides), and unintentionally added chemicals (e.g., cleaning products). Controls include using approved food-grade chemicals, sticking to safe additive levels, supplier guarantees, strict procedures for using cleaners, and correct storage and labeling.

• Physical Hazards: Foreign objects like metal fragments, glass, stones, plastic, wood splinters, and jewelry. Prevention includes using filters, sieves, metal detectors, X-ray machines, good equipment maintenance, and employee practices.

• Allergens: Specific proteins in foods (e.g., eggs, milk, peanuts, gluten, soy, seafood, tree nuts) that cause immune reactions. Control involves knowing raw material content, testing ingredients, managing production (e.g., separate lines, thorough cleaning), controlling staff movements, and accurate labeling.

• Food Fraud: Deliberate altering of food for financial gain, like diluting olive oil, substituting fish species, adding fillers to spices, or mislabeling origins. Prevention involves assessing supply chain vulnerabilities, vetting suppliers, and testing product authenticity.

Origins and Vectors of Contamination

Know how hazards get into food, whether through raw materials, poor handling, dirty equipment, or bad storage. Understanding the pathway helps control the hazard effectively.

Documented HACCP System

Legal Requirements

HACCP is often legally required. For example, in South Africa, the Foodstuffs, Cosmetics and Disinfectants Act and Regulation R908 mandate HACCP for certain food businesses.

International Standards

A major international standard is ISO 22000, a global food safety management system standard that requires a documented HACCP system. ISO 22000 integrates HACCP with GMP, communication, and continuous improvement, and it works alongside ISO 9001 for quality management.

Key Definitions

• Food Safety: Assurance that food won't cause harm.

• GMP (Good Manufacturing Practice): Basic hygiene and operational conditions needed.

• HACCP Certification: Formal recognition that your system meets standards.

• CCP (Critical Control Point): Essential step for control.

• Critical Limit: Specific measurable value at a CCP that separates safe from unsafe.

• Deviation: Failure to meet a critical limit.

• Corrective Action: What you do about a deviation.

• HACCP Plan: The entire documented system.

• Hazard: Biological, chemical, or physical agent.

• Hazard Analysis: Identifying and evaluating hazards.

• Monitor: Planned checks at a CCP.

• Validity: Proving your controls work.

• Verification: Confirming the system works correctly over time.

Seven Core Principles of HACCP

1. Conduct a hazard analysis.

2. Determine the CCPs.

3. Establish critical limits.

4. Establish monitoring procedures.

5. Establish corrective actions.

6. Establish verification procedures.

7. Establish documentation and record-keeping.

Putting Haccp

Practical Considerations

Key is a systematic approach that looks at everything from receiving ingredients to shipping the final product, considering potential consumer misuse, and seeing how steps connect.

The analysis covers ingredients, packaging, the product itself, and the production environment. Foundational elements like good hygiene and sanitation are essential prerequisites. Management commitment is critical, and the HACCP plan is unique to each operation and needs review when changes occur.

12 Steps for Applying HACCP

1. Assemble the HACCP team.

2. Describe the product in detail.

3. Identify who will use it.

4. Draw a flow diagram of the entire process.

5. Verify the flow diagram on-site.

6. List all hazards and analyze them.

7. Determine CCPs.

8. Set critical limits for each CCP.

9. Set up a monitoring system for each CCP.

10. Define corrective actions for deviations.

11. Establish how you'll verify the whole system works.

12. Set up documentation and record keeping.

Prerequisite Programs

HACCP needs prerequisite programs like:

• SOPs for sanitation

• GMP (Good Manufacturing Practice)

• GHP (Good Hygiene Practice)

• GSP (Good Storage Practice)

• GPP, GTP, GAP

These are fundamental good practices needed for handling food safely. HACCP focuses on critical points for specific hazards, assuming the basic hygiene foundation is solid.

Advantages of HACCP

Benefits include:

• Proactive hazard prevention.

• Cost savings (less waste, fewer recalls).

• Focused responses to issues.

• Staff involvement in safety.

• Consistently safer food.

• Legal compliance.

Starting Documentation

Document company details, food safety policy, product range, responsibilities, organizational chart, system review procedures, and control types. Cover specifics like checking incoming ingredients, controlling cleaning chemicals, facility design, sanitation, process controls, storage, final product specifications, recall plans, and employee training.

Conclusion

HACCP is a proactive, science-based system essential for food safety, originating from space travel needs and now a global standard. It involves systematically identifying and controlling hazards using seven core principles and relies on a solid foundation of good hygiene practices. Understanding HACCP provides insight into the rigorous effort behind ensuring food safety.
