Allergen Management: The Complete Guide for South African Food Businesses

A single undeclared allergen can trigger a recall, a lawsuit, or a consumer’s death. Allergen management is one of the highest-risk areas in any food business — and one of the most controllable when it is done properly.

What is allergen management?

Allergen management is the system a food business uses to keep allergens under control — from knowing which allergens are present, to preventing them from ending up in products where they are not declared, to labelling them clearly so consumers can make safe choices. It runs across the whole operation: purchasing, receiving, storage, production, cleaning, packaging and labelling.

Unlike many food hazards, allergens are not “removed” by cooking — a protein that a consumer reacts to remains a risk even in tiny amounts. That is why allergen management focuses on control and communication rather than elimination.

Why allergen management matters

The stakes are unusually high. A reaction to an undeclared allergen can range from discomfort to anaphylaxis and death. For the business, the consequences include product recalls, regulatory action, retailer de-listing, reputational damage and legal liability. There are three overlapping reasons to get it right:

Which allergens must be declared in South Africa?

South Africa’s Regulations Relating to the Labelling and Advertising of Foodstuffs (R146 of 2010) require the clear declaration of specified allergens. The commonly declared allergens include:

• Cereals containing gluten (such as wheat, rye, barley and oats) and their products
• Crustaceans and products of crustaceans
• Eggs and egg products
• Fish and fish products
• Peanuts, soybeans and their products
• Milk and dairy products (including lactose)
• Tree nuts and nut products
• Sulphites (sulphur dioxide) at or above the specified level

Building an allergen management programme

1. Identify every allergen on site. List the allergens in your raw materials, ingredients, rework and processing aids — not just the finished product.
2. Assess the risk. Map where each allergen is stored, handled and could cross-contact other products.
3. Control storage and flow. Segregate allergens, use dedicated or clearly identified equipment, and schedule production to minimise changeovers.
4. Clean and verify. Use validated cleaning between allergen and non-allergen production, and verify it works.
5. Label accurately. Declare allergens correctly and control label and packaging changes.
6. Control suppliers. Get allergen information from suppliers and manage changes to their recipes.
7. Train your people. Everyone who touches food must understand allergens and their role in controlling them.
8. Review it. Re-check the programme whenever recipes, suppliers or the site change.

Controlling allergen cross-contact

Cross-contact is when an allergen unintentionally transfers into a product that should not contain it — through shared equipment, utensils, hands, airborne dust (such as flour), rework or shared storage. Controls that work include physical or time segregation of allergen production, dedicated or colour-coded utensils and containers, controlling rework so it only goes back into products containing the same allergens, and careful scheduling so allergen-containing products run last before a full clean.

Cleaning and validation

Cleaning is the main defence against cross-contact on shared equipment. The key idea is that allergen cleaning must be validated — proven to remove the allergen to a safe level — and then routinely verified, for example by visual checks and allergen-specific swab or test-kit results. Cleaning procedures should be documented, and the equipment released for the next product only once the cleaning has been confirmed.

Allergen labelling done right

Correct labelling is how you communicate risk to the consumer. In practice that means declaring the required allergens clearly, using names consumers recognise, keeping the ingredient list and any allergen statement accurate and up to date, and tightly controlling label artwork so the wrong label never ends up on a product. Because labelling errors are a leading cause of allergen recalls, label and packaging control should be treated as a critical control. ASC’s labelling and regulatory advisory reviews labels against the current regulations before they go to print.

“May contain” and precautionary labelling

Precautionary statements such as “may contain traces of…” are meant to warn of an unavoidable, genuine cross-contact risk that cannot be fully removed — not to be used as a blanket disclaimer to avoid doing the control work. Overusing “may contain” reduces choice for allergic consumers and can erode trust. The right approach is to control the risk first, and use a precautionary statement only where a real, assessed risk remains.

Common allergen management mistakes

• Relying on “may contain” instead of controlling the actual risk
• Missing an allergen that enters through a minor ingredient or processing aid
• Not updating labels when a supplier changes a recipe
• Unvalidated cleaning between allergen and non-allergen runs
• Rework containing allergens going back into the wrong product
• Staff who have never been trained to recognise allergen risks
• No control over label artwork and packaging changes
