SANS 10330 Hazard Analysis: Product Description Guide (Stage 2)

Effective hazard analysis begins long before you map out your process flow or identify critical control points. It starts with truly understanding your product.

Effective hazard analysis begins long before you map out your process flow or identify critical control points. It starts with truly understanding your product.

SANS 10330 Stage 2 requires you to create a comprehensive product description, which serves as the foundation for identifying every biological, chemical, and physical hazard that could compromise food safety. This stage is where many HACCP coordinators either build a solid foundation for their entire food safety system or create gaps that auditors will inevitably find.

Think of the product description as your food product's complete identity card. Just as a medical chart contains everything a doctor needs to diagnose and treat a patient, your product description must contain everything your HACCP team needs to identify hazards and design appropriate controls.

Understanding Stage 2: Why Product Description Matters for Hazard Analysis

Before diving into the technical details, let's establish why SANS 10330 places such emphasis on product description as a distinct preliminary step. The standard recognizes that you cannot conduct meaningful hazard analysis without first documenting what you are actually making. Each characteristic of your product introduces, eliminates, or modifies potential hazards.

Consider two seemingly similar products: fresh mayonnaise and shelf-stable mayonnaise. Both contain eggs, oil, and acid, but their hazard profiles are dramatically different because of processing, pH levels, water activity, and storage conditions. Without detailed product descriptions, your hazard analysis would miss critical distinctions, potentially leading to inadequate controls and ultimately to foodborne illness outbreaks or product recalls.

Stage 2 product description feeds directly into Stage 3 (intended use identification) and Stage 5 (hazard analysis). The information you document here becomes the reference point for every subsequent HACCP decision. If your product description is incomplete or inaccurate, every downstream activity will be compromised.

The Seven Essential Elements of Product Description

SANS 10330 requires seven specific elements in your product description. Each element serves a distinct purpose in hazard identification.

1. Composition: Cataloging Every Ingredient and Additive

The composition section requires a complete list of all raw materials, ingredients, additives, and potential allergens used in the product. This is not simply copying your recipe; it is creating a comprehensive inventory that identifies hazard sources.

Why this matters for hazard analysis: Every ingredient brings its own hazard profile. Raw materials can introduce biological hazards such as Salmonella in eggs, Listeria in dairy, or pathogenic E. coli in raw meat. Ingredients can carry chemical hazards including pesticide residues on produce, antibiotic residues in animal products, or heavy metals in certain spices.

Practical approach: List every ingredient by its common name and specify its function in the product. For allergens, be explicit and comprehensive. If you use egg-containing ingredients like mayonnaise in your product, state both the ingredient and the allergen it contains. Document any processing aids even if they do not remain in the final product.

2. Physical and Chemical Properties: The Science Behind Safety

This section requires documenting scientific properties that affect food safety, particularly pH (acidity) and water activity. These properties are not academic details; they are fundamental controls that determine whether harmful microorganisms can survive and multiply in your product.

Why this matters: pH and water activity are intrinsic factors that control microbial growth. Products with pH below 4.6 and water activity below 0.85 are generally considered low-risk for pathogenic bacterial growth. Products with pH above 4.6 and water activity above 0.85 provide ideal conditions for bacterial pathogens like Clostridium botulinum, Listeria monocytogenes, and Salmonella species.

Practical approach: Measure and document actual pH and water activity values for your products. Do not estimate or assume these values based on recipes. Document the testing method and equipment used, as auditors will ask for this information.

3. Safety Treatments: Documenting Your Kill Steps

Safety treatments are the methods you use to kill or inhibit microorganisms. These include cooking, pasteurization, freezing, salting, smoking, and fermentation. This element documents the processing steps specifically designed to eliminate or control hazards.

Why this matters: Safety treatments are often your primary controls for biological hazards. A cooking step that achieves specific time-temperature combinations can eliminate vegetative pathogens. Understanding which treatments your product receives tells you which hazards are controlled during processing versus which require other controls.

Practical approach: For each safety treatment, specify the parameters that make it effective. For cooking, document target internal temperatures and holding times. For freezing, document freezing rates and storage temperatures. Include scientific justification demonstrating that your treatment parameters are adequate to control the identified hazards.

4. Packaging Systems: Your Product's Protective Barrier

Document how the product is packaged, including primary packaging materials, secondary packaging, and any modified atmosphere or vacuum packaging systems. Packaging is a critical food safety control, not merely about presentation.

Why this matters: Packaging prevents recontamination after processing, controls oxygen availability, and protects against physical hazards during distribution. Vacuum packaging and modified atmosphere packaging create anaerobic conditions that prevent aerobic spoilage organisms but can allow anaerobic pathogens like Clostridium botulinum to thrive if other controls are not adequate.

5. Storage Conditions: Maintaining Safety from Production to Consumption

Specify storage temperature requirements and any other conditions necessary to maintain product safety. This applies to storage at your facility, during distribution, at retail, and at the consumer level.

Why this matters: Storage temperature is a critical control for time-temperature sensitive products. Refrigeration slows but does not stop microbial growth — psychrotrophic pathogens like Listeria monocytogenes can grow at refrigeration temperatures. Be specific: instead of "keep refrigerated," specify "store at 0–4°C."

6. Shelf Life: Time as a Food Safety Factor

Document the duration the product remains safe to consume under specified storage and usage conditions. Shelf life determination must account for both quality degradation and safety concerns.

Why this matters: Even refrigerated products have finite shelf lives because psychrotrophic pathogens slowly multiply over time. Base shelf life on scientific evidence — conduct challenge studies that specifically test for pathogen growth under realistic storage conditions, including temperature abuse scenarios.

7. Distribution Methods: Controlling Hazards Beyond Your Facility

Describe how the product is transported to customers, including transportation method, temperature control requirements, and any special handling instructions. Distribution extends your HACCP system beyond your facility walls.

Why this matters: Temperature abuse during distribution is one of the most common causes of foodborne illness outbreaks. If your product requires temperature-controlled transport but you have no verification system, you cannot be certain your safety controls remain effective.

Connecting Product Description to Hazard Categories

Biological Hazards: Microorganisms and Parasites

For South African food manufacturers, particularly relevant biological hazards include Salmonella species in poultry and eggs, Listeria monocytogenes in ready-to-eat refrigerated products, Staphylococcus aureus in manually handled products, Clostridium botulinum in low-acid canned products or vacuum-packed foods, and pathogenic E. coli in ground meat and fresh produce. Your product description tells you which of these hazards apply to your specific products.

Chemical Hazards: From Ingredients to Packaging

In South Africa, particularly relevant chemical hazards include pesticide residues on fresh produce, mycotoxins (especially aflatoxins) in groundnuts and maize products, heavy metals in fish and certain spices, veterinary drug residues in meat and dairy, histamine in fish products, and allergens across all product categories.

Physical Hazards: Foreign Objects That Cause Harm

Common physical hazards in South African food production include metal fragments from processing equipment, glass from broken lights or containers, stones and soil from agricultural products, bone fragments in deboned products, and plastic pieces from packaging materials.

Common Mistakes in Product Description and How to Avoid Them

• Using vague or generic descriptions. Describing a product as "cooked meat product" or "bakery item" provides no specific information for hazard analysis. Specify the product name, all ingredients with percentages, and target parameters.
• Omitting allergen declarations. Allergens are chemical hazards that must be explicitly identified. South African regulations require declaration of cereals containing gluten, crustaceans, eggs, fish, peanuts, soybeans, milk, tree nuts, celery, mustard, sesame seeds, sulphites, lupin, and molluscs.
• Failing to document pH and water activity. Measure these values using calibrated instruments and document the results. Do not rely on estimates.
• Inadequate treatment descriptions. Simply stating "product is cooked" is insufficient. Specify time-temperature parameters that make the step effective.
• Ignoring distribution temperature requirements. "Keep refrigerated" is too vague. Document the maximum temperature your product can tolerate and for how long.

Moving Forward: From Product Description to Hazard Analysis

Stage 2 product description creates the information foundation for your entire HACCP system. When you move to Stage 5 hazard analysis, you will return to these product descriptions repeatedly. The time you invest in creating thorough, accurate product descriptions will pay dividends throughout your HACCP development and implementation.

Remember that product descriptions are living documents. When you reformulate products, change suppliers, modify processing parameters, or update packaging, you must revise your product descriptions and reassess hazards. Establish a procedure for reviewing and updating product descriptions at least annually and whenever changes occur.
