What Is Food Allergen Training and Why Is It Critical for Food Workers?

Food allergen training teaches food handlers and front-of-house staff how to identify the 14 regulated allergens, prevent cross-contamination, and give customers allergen information that is accurate every time. UK food law requires every food business to tell customers if any of the 14 allergens are used as ingredients in the food it sells, and to train food handlers in food safety matters relevant to their work. Allergen training is how staff meet both duties in practice. Getting it wrong is not a paperwork problem. Restaurant owners have been jailed for manslaughter after customers died from undeclared allergens. This guide explains what the law actually requires, the 14 allergens, the separate rules for prepacked, prepacked for direct sale and loose food, how cross-contamination happens, and how the learndirect CPD-accredited allergen course fits in.

If you also need general food hygiene training, read our companion guide, Food Hygiene Certificate Level 2. This article focuses on allergens.

Why allergen training matters

The Food Standards Agency's Patterns and Prevalence of Adult Food Allergy (PAFA) report, published in May 2024, estimates that around 6% of UK adults, roughly 2.4 million people, have a clinically confirmed food allergy. For people with severe allergies, a tiny amount of the wrong ingredient can cause anaphylaxis, a life-threatening reaction that needs emergency treatment.

Customers with allergies have no way of checking a dish themselves. They rely entirely on the person who takes the order, the person who cooks it, and the information the business gives them. That is why allergen knowledge has to sit with every member of staff who handles food or talks to customers about it, not just the chef or the manager.

What the law actually requires

The duty to give allergen information

Allergen information is governed by assimilated Regulation (EU) No 1169/2011 on the provision of food information to consumers (often called FIC). In England it is enforced through the Food Information Regulations 2014, which came into force on 14 July 2014, and equivalent regulations apply in Scotland, Wales and Northern Ireland. Food businesses must declare the presence of any of the 14 allergens listed in Annex II when they are used as an ingredient or processing aid and are still present in the finished food. The information must be accurate.

The duty to train

No regulation names a specific allergen course. The training duty comes from food hygiene law. Annex II, Chapter XII of assimilated Regulation (EC) No 852/2004 requires food business operators to ensure that food handlers are supervised and instructed or trained in food hygiene matters commensurate with their work activity. Allergen control is part of food safety. In practice, that means anyone who prepares food, takes orders or answers customers' questions must be trained well enough to get allergen information right.

Natasha's Law

Since 1 October 2021, under the Food Information (Amendment) (England) Regulations 2019, widely known as Natasha's Law, food that is prepacked for direct sale (PPDS) must carry the name of the food and a full ingredients list with the 14 allergens emphasised. PPDS food is packed on the same premises where it is sold, before the customer orders it. Examples include sandwiches made and wrapped in the shop that morning, or salads packed at a deli counter.

The 14 regulated allergens

The FSA's allergen labelling technical guidance lists the 14 allergens that must be declared:

1. Celery, including celeriac, and products made from it.
2. Cereals containing gluten: wheat (including spelt and Khorasan wheat), rye, barley and oats. The specific cereal must be named.
3. Crustaceans, such as prawns, crabs, lobster and crayfish.
4. Eggs.
5. Fish.
6. Lupin, a legume sometimes used in flour.
7. Milk, including lactose.
8. Molluscs, such as mussels, oysters, scallops, snails and squid.
9. Mustard.
10. Peanuts.
11. Sesame.
12. Soybeans.
13. Sulphur dioxide and sulphites, where present at more than 10 mg/kg or 10 mg/litre (as total sulphur dioxide) in the food as consumed.
14. Tree nuts: almonds, hazelnuts, walnuts, cashews, pecans, Brazil nuts, pistachios and macadamia nuts. The specific nut must be named.

The regulations include a small number of exceptions, such as fully refined soybean oil and wheat-based glucose syrups. Customers may also be allergic to foods outside the 14, such as kiwi or other fruits. You are not legally required to declare those, but staff should never guess when asked.

Three types of food, three sets of rules

• Prepacked food. Food packed before it reaches the business that sells it, such as a branded chocolate bar or a jar of sauce. Allergens must be emphasised in the ingredients list, for example in bold.
• Prepacked for direct sale (PPDS). Food packed on the premises before the customer orders it. Since Natasha's Law, it needs a full label with the name of the food and an ingredients list with allergens emphasised.
• Non-prepacked (loose) food. Meals in restaurants and cafés, takeaway food, and loose items at a counter. Allergen information must be available for every dish. The FSA's best practice guidance published in March 2025 says businesses should make allergen information easily available in writing and make sure staff can support it with a conversation.

The FSA guidance also says written information should cover all 14 allergens, name the specific nut or cereal, be kept accurate and regularly reviewed, and be easy to find. If it is not on the main menu, the menu or a sign should tell customers where to get it. Staff need to know where it is and how to use it. That is a training point in itself.

How cross-contamination happens

An allergen does not have to be an ingredient to harm someone. Cross-contamination (sometimes called cross-contact) happens when allergen proteins move from one food to another. Common routes include:

• shared chopping boards, knives, scoops, tongs and mixing bowls;
• shared fryer oil, for example cooking battered fish and chips in the same oil;
• flour and other powders drifting through the air in a busy kitchen;
• hands, aprons, tea towels and gloves;
• storage, where open containers sit next to each other or above other foods;
• substitutions, where a supplier changes a product or the kitchen runs out of an ingredient and uses an alternative without checking it;
• garnishes and toppings added at the pass.

Good practice includes separate equipment for allergen-free orders where possible, thorough cleaning with hot soapy water between tasks, washing hands with soap and water rather than relying on sanitiser gel, clear labelling of stored ingredients, and checking every delivery against the product specification.

"May contain" labels

Precautionary allergen labels such as "may contain nuts" are voluntary. The FSA technical guidance says they should only be used where there is an unavoidable risk of cross-contamination identified through a risk assessment, and must not mislead customers. They are not a substitute for good allergen management.

Taking an allergen order: what good looks like

1. Take it seriously. Treat every allergy or intolerance request as genuine.
2. Check, never guess. Use the written allergen information or the recipe record. If you are unsure, ask the person in charge.
3. Tell the kitchen clearly. Flag the order on the ticket and say it out loud if that is your process.
4. Prepare it separately. Clean equipment and surfaces, wash hands, and use fresh ingredients from closed containers.
5. Keep it separate. Serve the dish separately and make sure it reaches the right person.
6. Be honest about risk. If you cannot be confident a dish is safe, say so. Declining an order is better than causing a reaction.

If a customer has a reaction

Signs of a serious reaction can include swelling of the lips, tongue or throat, difficulty breathing or swallowing, wheezing, feeling faint, and collapse. Call 999 immediately and say it is anaphylaxis. If the person has an adrenaline auto-injector, help them use it. Follow the advice of the emergency operator and stay with them. A first aid course will cover this in more depth.

Enforcement and consequences

Local authority environmental health and trading standards officers enforce allergen rules. Under the Food Information Regulations 2014, officers can serve improvement notices, and failing to comply with one is a criminal offence. Officers can also prosecute under section 14 of the Food Safety Act 1990 for selling food that is not of the nature, substance or quality the purchaser demanded. Serving a dish containing an allergen the customer asked to avoid is a classic example. The old "GBP 20,000 fine" figure is out of date: since 12 March 2015, magistrates' courts in England and Wales have been able to impose unlimited fines for the most serious offences.

The most serious cases go further. In 2016, the owner of an Indian takeaway in North Yorkshire was jailed for six years for manslaughter after a customer with a peanut allergy, who had asked for no nuts, died from anaphylaxis. The court heard the owner had used a cheaper ingredient that contained peanuts.

Common questions

Is food allergen training a legal requirement?
The law does not name a specific allergen course. It requires food businesses to give accurate allergen information for the 14 regulated allergens, and requires food handlers to be supervised and instructed or trained in food hygiene matters relevant to their work. Allergen training is the practical way to meet both duties and to prove it.

What is the difference between a food allergy and a food intolerance?
A food allergy involves the immune system and can cause a severe, fast reaction, including anaphylaxis. An intolerance does not involve the immune system in the same way and usually causes digestive symptoms. Coeliac disease is an autoimmune condition triggered by gluten. Staff should treat every request with the same care, because they cannot tell from the outside how severe someone's condition is.

Can allergen information for loose food be given verbally?
Allergen information must be available for every dish. The FSA's best practice guidance, published in March 2025, says businesses should provide it in writing and make sure staff can support it with a conversation. If the information is not on the menu, customers should be told clearly where to find it.

Does washing remove allergens from equipment?
Thorough cleaning with hot soapy water removes allergen residues from most equipment and surfaces. Quick wipes and sanitiser sprays are not enough on their own. For customers with severe allergies, many businesses also use separate, clearly marked equipment.

What does Natasha's Law mean for my business?
If you sell food that is packed on your premises before the customer orders it, such as pre-wrapped sandwiches or salads, each item must carry the name of the food and a full ingredients list with the 14 allergens emphasised. It has applied since 1 October 2021.

How often should allergen training be refreshed?
The law does not set a fixed interval. Refresh it when menus, recipes, suppliers or procedures change, after any incident or near miss, and periodically to keep knowledge current. Many businesses refresh annually.

How much does the learndirect allergen course cost?
GBP 25 for a single learner, with volume pricing from 10 learners. The course takes around 60 minutes and the CPD-accredited certificate is available to download immediately.
