Food allergies and intolerances, the main allergens and the law on allergen information, and the special dietary needs the industry must cater for, including medical, lifestyle and religious diets.

What this dot point is asking

You need to explain the difference between a food allergy and a food intolerance, name the main allergens and the law on allergen information, describe how to prevent reactions, and outline the special dietary needs the industry must cater for, including medical, lifestyle and religious diets. CCEA examiners reward precise definitions, accurate examples and the ability to apply safe practice to a food business. This matters because getting allergens wrong can be life-threatening, and catering well for special diets is both a legal duty and good business.

Allergy and intolerance

Customers react to foods in different ways, and the difference matters.

The main allergens and the law

By law, food businesses must give customers information about the main allergens in the food they serve. There are 14 named allergens that must be declared, which include:

• Cereals containing gluten (such as wheat, barley, rye and oats).
• Crustaceans (such as prawns and crab) and molluscs (such as mussels).
• Fish, eggs and milk.
• Peanuts and tree nuts (such as almonds and walnuts).
• Soya, sesame, celery, mustard, lupin and sulphur dioxide (sulphites).

A food business must be able to tell a customer which of these allergens are in a dish, on the menu or by asking staff. Pre-packed foods must list allergens on the label.

Preventing allergic reactions

Giving information is not enough on its own; a kitchen must also prevent the allergen reaching the customer:

• Accurate information - know exactly what is in every dish, including sauces and garnishes.
• Train staff - so they take allergy questions seriously and answer correctly.
• Prevent cross-contamination - use separate equipment, utensils and preparation areas for allergen-free dishes, and clean thoroughly, because even a trace can cause a reaction.
• Take requests seriously - never guess; if unsure, say so.

Special dietary needs

Beyond allergies, the industry must cater for many special diets, which fall into three groups:

• Medical diets - needed for health, such as gluten-free for coeliac disease, low-sugar for diabetes, low-salt or low-fat for heart health, and allergen-free diets.
• Lifestyle diets - chosen by the customer, such as vegetarian (no meat or fish) and vegan (no animal products at all).
• Religious and cultural diets - such as halal (permitted for Muslims), kosher (permitted for Jews), and avoiding certain meats for other faiths.

A good business offers a range of options so all these customers can eat well, which also attracts more custom.

Worked example: catering for a customer with an allergy

A common exam task asks how to serve a customer with a specific need safely.

Why this matters

Allergens are a matter of life and death, and the law requires every food business to manage them. Catering well for special diets also brings in more customers and builds a good reputation. This topic links closely to food safety, menu planning and customer service. In the exam, the most valuable skills are to define allergy and intolerance correctly, name allergens, and explain how a business gives information and prevents cross-contamination for a described customer.
