Allergen Labelling for South African Food Businesses: the Basics
A customer asks "does this contain nuts?" — and the answer your team gives can be the difference between a normal meal and an ambulance. Food allergies are common, potentially life-threatening, and entirely manageable in a commercial kitchen if you treat them as a system rather than a memory test.
This guide covers the major allergens, how allergen cross-contact happens, and the simplest honest way for a small food business to handle allergen questions safely.
The allergens that matter
Food-labelling rules recognise a set of major allergens that account for the vast majority of serious reactions. The internationally recognised list covers:
- Cereals containing gluten (wheat, rye, barley, oats)
- Crustaceans (prawns, crab, lobster)
- Eggs
- Fish
- Peanuts
- Soybeans
- Milk (including lactose)
- Tree nuts (almonds, cashews, walnuts, pistachios and others)
- Celery
- Mustard
- Sesame
- Sulphur dioxide and sulphites (above a threshold level — common in dried fruit, wine and some processed ingredients)
- Lupin
- Molluscs (mussels, oysters, squid)
You don't need to memorise the chemistry — you need to know which of these are in each dish you serve. That means knowing your ingredients, which in turn means reading the labels of everything that comes in the door.
Cross-contact: the hidden route
A dish can contain an allergen without it being an ingredient — through cross-contact. A trace of peanut from a shared fryer, a knife that cut a cheese sandwich and then the "dairy-free" order, a board that had sesame bread on it. For an allergic customer, a trace can be enough.
This is why allergen control is physical, not just a list. The tools that prevent cross-contamination of germs — separate boards, separate utensils, cleaning between tasks — are the same tools that prevent allergen cross-contact. Our colour-coded chopping board guide covers the dedicated (allergen-free) board approach.
The honest answer beats the confident guess
The most dangerous words in a kitchen are "I think it's fine." If a team member isn't sure whether a dish contains an allergen, the only safe answer is to check — against a written recipe/spec sheet — or to say so plainly. Never guess. A customer with a real allergy would rather hear "let me confirm with the kitchen" than get a confident wrong answer.
The simplest safe setup for a small kitchen
- Know your dishes. For each menu item, list which of the major allergens it contains, based on the actual ingredients you use (including sauces, stocks and garnishes — common hiding places).
- Keep it written and current. A single allergen matrix — dishes down one side, allergens across the top, a mark where they meet — updated whenever a recipe or supplier changes.
- Train the answer. Every front-of-house and kitchen person should know to check the matrix, not guess, and to tell the customer honestly if something can't be guaranteed.
- Control cross-contact for allergen orders. Clean board, clean knife, clean hands/gloves, fresh oil if frying — treat an allergen-free order as a separate prep task.
- Be honest about "may contain". If your kitchen handles nuts everywhere, you can't promise nut-free. Say so. Customers with severe allergies rely on that honesty to stay safe.
How this fits your wider obligations
Allergen information sits inside your general food-safety duties under Regulation R638 (safe food, accurate description, no misleading the customer). The practical effect is simple: you must be able to tell a customer, honestly, what's in their food. The matrix and the training above are how a small business does that reliably. Our R638 guide covers the regulation itself.
Frequently asked questions
Do I legally have to give allergen information in South Africa?
You must not mislead customers about what they're eating, and you must serve safe food — both flow from R638 and general food law. In practice that means being able to answer allergen questions accurately. A written allergen matrix is the recognised way to do it and the first thing a diligent operator shows an inspector or a concerned customer.
Is "may contain nuts" enough to protect me?
A "may contain" note is honest where cross-contact is genuinely possible, but it's not a substitute for knowing your ingredients or for controlling cross-contact on allergen-free orders. Overusing "may contain everything" on every dish tells allergic customers you don't actually manage allergens — and it drives them away.
What's the most common mistake?
Guessing. The recipe says "mayonnaise" and the team forgets that mayonnaise contains egg; the stock cube contains gluten; the garnish contains sesame. Read every ingredient label, and update the matrix when any supplier or product changes.
Do I need a separate purple/allergen board?
If you offer allergen-free prep, a dedicated board and knife (cleaned first, used only for that task) is the simplest physical control against cross-contact. It's not a legal requirement, but it's the easiest way to make "we take allergens seriously" physically true.
