Identify the regulated allergen categories and recognise where they can be hidden in ingredients, recipes and shared equipment.

Records your study progress, not an assessment result or certificate.

Key points

  • Recognise all fourteen categories and check compound ingredients rather than relying on a food name.
  • Check hidden cereal, milk and egg ingredients and the residues carried by surfaces or utensils.
  • Distinguish peanuts, specific tree nuts and sesame, and control their transfer through utensils and storage.
  • Check fish, crustaceans and molluscs as distinct categories, including sauces and shared preparation equipment.
  • Check soya, mustard, celery and lupin in prepared ingredients and report supplier or recipe changes.
  • Check preserved ingredients and the applicable sulphite information without guessing a threshold or diagnosing the customer.
  • Check every current component and report changes; familiar packaging and dietary descriptions are not complete allergen information.

Lesson guide

2.1 The fourteen allergen categories

The course names celery, cereals containing gluten, crustaceans, eggs, fish, lupin, milk, molluscs, mustard, peanuts, tree nuts, sesame, soya, and sulphur dioxide and sulphites above the applicable level. This regulated list supports food information; it does not mean nobody can react to another food. Listen to the customer's specific need and check the actual ingredients.

Allergens may be a small component of a larger ingredient. Bread can contain milk or egg; dressings and marinades may contain mustard; hummus may contain sesame through tahini; flour, breadcrumbs, batter and pastry can introduce gluten-containing cereals. Read the current label and recipe rather than assuming the food name tells the whole story. Include toppings, sauces, seasonings and the method of preparation in the check.

2.2 Gluten-containing cereals, milk and eggs

Wheat, rye, barley and oats are discussed as cereals to consider in gluten-related checks. Flour, couscous, semolina, breadcrumbs, batter, pasta and thickening ingredients can place these cereals in foods that are not obviously bread. Milk can appear as butter, cream, cheese, milk powder, whey or casein in sauces, mash, baked goods and prepared meals. Eggs can be in mayonnaise, cakes, glazes and pasta.

Check the preparation environment as well. Flour on a surface can affect nearby food; a cheese knife or mayonnaise spoon can carry milk or egg residue to another order. A dairy-free request therefore needs an ingredient check and the appropriate clean equipment and handling. Use the exact current product information, and ask when a component or a gluten-free suitability claim is uncertain.

2.3 Peanuts, tree nuts and sesame

Peanuts and tree nuts are separate allergen categories. The recording identifies tree nuts including almonds, hazelnuts, walnuts, cashews, pecans, Brazil nuts, pistachios and macadamias. Peanut butter, satay sauce, toppings and snacks are possible peanut sources. Tree nuts can appear in pesto, cakes and nut butters. Sesame can be in tahini, buns, breads, crackers and hummus, not only visible seeds.

A knife shared between a nut-containing cake and a plain cake, a spoon reused from peanut sauce or seeds falling into another ingredient can create cross-contact. Keep ingredients identified and stored according to the procedure, and use effective cleaning and suitable separate utensils where required. Do not treat “nuts” as a vague substitute for the exact customer request or the exact ingredient category shown in the records.

2.4 Fish, crustaceans and molluscs

Fish, crustaceans and molluscs are distinct categories; “seafood” is too broad to answer a specific allergen question. Fish can be an obvious fillet or an ingredient in fish sauce, anchovy-containing dressing, curry paste, stock or a prepared sauce. Crustaceans include prawns, shrimp, crab, lobster and crayfish. Molluscs include mussels, clams, oysters, scallops, squid, octopus, cockles, whelks and snails.

Shared fryer oil, a grill, tongs or a board can transfer relevant residues. An ingredient that seems unrelated to a fish dish may still contain a fish-based flavouring. Check the current specification and recipe for the actual product, then confirm how it is prepared. Do not assume that a customer who avoids one of these categories avoids all three, or that their specific request can be ignored because the menu uses a general word.

2.5 Soya, mustard, celery and lupin

Soya can appear in soya sauce, tofu, soya drinks, meat substitutes, flour, protein ingredients, chocolate and bread. Check the origin of a named ingredient such as lecithin rather than assuming its source. Mustard may be present in dressings, marinades, mayonnaise, spice mixtures or chutney, including powder and seed forms. Celery can be hidden in stock, soup, seasoning or stuffing. Lupin can occur in flour mixtures, bread, pastry, pasta and gluten-free products.

These ingredients may not have a strong taste or an obvious appearance. A stock or seasoning change can alter the allergens in a whole dish. Check current supplier labels and recipes before use and report differences so the matrix and customer information can be updated. A gluten-free or vegan description does not remove the need to check other allergens.

2.6 Sulphur dioxide and sulphites

Sulphur dioxide and sulphites can be used as preservatives in foods and drinks. The recording gives examples such as dried fruit, wine, cider, beer, bottled citrus juice, pickles, vinegar, sauces, some potato products, prawns, sausages and processed foods. Their presence depends on the actual product and the applicable declaration level, so the examples are prompts to check, not a claim that every version contains them.

Use the current label, specification, matrix and recipe, including preserved components used within a dish. The source discusses breathing reactions, particularly for some people with asthma; staff should not diagnose or decide that a stated sensitivity is unimportant. Follow the customer's request and the workplace procedure. This recording does not supply a numeric threshold, so do not invent one from memory when answering a customer.

2.7 Hidden allergens and changing recipes

A finished dish can contain several allergens through its components. Curry sauce may include milk, mustard, celery, nuts or soya; soup may contain flour, milk, celery or fish stock. A bun, dressing and garnish can introduce different allergens into one sandwich. Desserts, chocolate, gravy, spice mixtures, breadcrumbs and flavourings deserve the same detailed check as the main ingredient.

A familiar packet is not a guarantee that the recipe is unchanged. A new mayonnaise, bread or sauce can differ from the previous version, and similar packaging can make that difference easy to miss. Read each current label, compare it with the recipe and approved information, and report changes before using the product for a sensitive order. “Vegan” and “gluten-free” are not shorthand for free from every other allergen.

In practice

The gluten-free bake

Source teaching example rewritten as a formative scenario; not a real reported incident

A flour blend is described as gluten-free and its current label includes lupin.

Can it be called suitable for every allergy request?

Check the customer's specific need and the full current ingredients and preparation controls. Do not turn the gluten-free description into an all-allergen guarantee.

Lupin can occur in gluten-free products; dietary descriptions do not replace checks for other allergens.

The changed mayonnaise

Source teaching example rewritten as a formative scenario; not a real reported incident

A new delivery looks like the usual mayonnaise, but its ingredient details differ.

Should the old matrix remain the basis for answers?

Check the current label and recipe, stop unsupported answers and report the change so approved records can be updated before use.

Egg, mustard or soya information can change between products even when packaging looks familiar.

Reflect on your learning

What should you do when a supplier changes a familiar product?

Select one answer.

Are peanuts and tree nuts the same allergen category?

Select one answer.

For your own learning — not the certification assessment.

FAQs

Are the fourteen regulated allergens the only foods anyone can react to?

No. They are the regulated categories introduced here, not a complete list of every individual allergy. Listen to the specific request and use current product information.

Can a plain-looking sauce contain an allergen?

Yes. Stocks, flavourings, spice mixtures, mayonnaise and other components may contain allergens. Check the complete recipe and current labels rather than appearance.

What sulphite threshold does this recording teach?

It says declaration applies above the relevant level but gives no number. Use current official guidance and the actual product information; do not attribute an invented numeric rule to the video.

Can the three seafood categories be treated as one answer?

No. Fish, crustaceans and molluscs are separate categories in the recording. Check the exact ingredient and the customer’s specific request.

[0:00] Welcome to lesson 2.1, overview of the
[0:02] 14 regulated allergens.
[0:05] In the UK, food businesses must provide
[0:07] information when any of the 14 regulated
[0:10] allergens are used as ingredients in
[0:12] food or drink. The 14 allergens are
[0:15] celery, cereals containing gluten,
[0:17] crustaceans, eggs, fish, lupin, milk,
[0:21] mollusks, mustard, peanuts, tree nuts,
[0:24] sesame, soya, and sulfur dioxide or
[0:27] sulfites above certain levels.
[0:30] These allergens must be taken seriously
[0:32] because they can cause allergic
[0:33] reactions, intolerances, or other
[0:36] serious health effects in some
[0:37] customers. At level two, you do not only
[0:40] need to remember the list. You also need
[0:43] to understand where these allergens may
[0:45] appear in real food work. For example,
[0:49] milk may be found in butter, cream,
[0:51] cheese, sauces, desserts, and some bread
[0:54] products.
[0:55] Mustard may be in dressings, marinades,
[0:57] and mayonnaise.
[0:59] Sesame may be on burger buns, in hummus,
[1:02] tahini, sauces, or seed mixes.
[1:05] Gluten may be in flour, breadcrumbs,
[1:08] batter, pastry, pasta, and thickened
[1:11] sauces. Allergens can also be hidden
[1:13] inside boughtin ingredients, ready-made
[1:16] sauces, spice mixes, stock powders,
[1:18] desserts, marinades, and processed
[1:21] foods. This is why staff must always
[1:24] check accurate information before
[1:25] answering customers. A food may not look
[1:28] like it contains an allergen, but the
[1:30] recipe, supplier label, or preparation
[1:33] method may show otherwise.
[1:35] The key message is simple. Know the 14
[1:37] regulated allergens. Understand where
[1:39] they may be found and never rely on
[1:41] appearance, memory, or guesswork.
[1:45] Welcome to lesson 2.2, cereals
[1:47] containing gluten, milk, and eggs. In
[1:50] this lesson, we will look at three major
[1:52] allergen groups that appear in many
[1:54] everyday foods. Cereals containing
[1:56] gluten, milk, and eggs. Cereals
[1:59] containing gluten include wheat, rye,
[2:02] barley, and oats. Gluten may be found in
[2:05] flour, bread, pasta, pastry, cakes,
[2:09] biscuits, breadcrumbs, batter, pizza
[2:11] bases, sauces, soups, and some processed
[2:14] foods. Wheat can also appear in
[2:17] ingredients such as couscous, semolina,
[2:19] and some thickeners.
[2:21] Milk is another common allergen. It may
[2:24] be found in butter, cheese, cream,
[2:27] yogurt, milk powder, whey, casein,
[2:30] custard, chocolate, desserts, sauces,
[2:33] mashed potato, baked goods, and some
[2:35] ready-made meals. Eggs may be found in
[2:38] cakes, mayonnaise, dressings, pasta,
[2:41] pastry, battered foods, desserts,
[2:44] glazing, sauces, and some processed
[2:46] products. These allergens can be
[2:49] obvious, but they can also be hidden.
[2:52] For example, a sauce may contain milk
[2:54] powder, a burger bun may contain egg, or
[2:56] a soup may be thickened with wheat
[2:58] flour. Cross contact is also a risk. A
[3:02] gluten-free order may become unsafe if
[3:04] prepared on a flower-covered surface. A
[3:07] dairfree sandwich may become unsafe if
[3:09] made with a knife used for cheese. An
[3:12] egg-free order may be affected by shared
[3:14] mayonnaise utensils.
[3:16] As a level two food handler, you must
[3:19] check labels, recipes, and allergen
[3:21] information before answering customers.
[3:24] You must also follow cleaning,
[3:26] separation, and communication
[3:27] procedures.
[3:29] The key messages: gluten, milk, and eggs
[3:31] are common in food businesses, so never
[3:33] assume they are absent.
[3:36] Always check. Welcome to lesson 2.3.
[3:40] Peanuts, tree nuts, and sesame. Peanuts,
[3:43] tree nuts, and sesame are important
[3:45] allergens because they can cause serious
[3:47] reactions in some customers and they are
[3:49] often found in foods where staff may not
[3:52] expect them. Peanuts are not the same as
[3:54] tree nuts. Peanuts are legumes, but they
[3:58] are still one of the 14 regulated
[3:59] allergens.
[4:01] They may be found in peanut butter, saté
[4:03] sauce, desserts, sauces, snacks, oils,
[4:07] toppings, confectionary, and some world
[4:09] food dishes. Tree nuts include almonds,
[4:12] hazelnuts, walnuts, cashews, pecans,
[4:16] Brazil nuts, pistachios, and macadamia
[4:19] nuts. These may be found in cakes,
[4:22] biscuits, pastries, desserts, pesto, nut
[4:25] butters, cereals, toppings, salads,
[4:29] chocolates, and sauces.
[4:31] Sesame may be found in sesame seeds,
[4:33] tahini, hummus, burger buns, bread,
[4:36] crackers, sauces, dressings, and some
[4:39] spice mixes.
[4:40] These allergens can also spread through
[4:42] cross contact.
[4:44] For example, a knife used to cut a
[4:46] nutcake could transfer nut traces to
[4:48] another dessert. Sesame seeds from
[4:51] burger buns may fall into preparation
[4:53] areas. A spoon used in peanut sauce
[4:56] could contaminate another source. For
[4:59] customers with serious allergies, even a
[5:01] small amount can be dangerous. As a
[5:04] level two food handler, you must keep
[5:06] allergen ingredients labeled, stored
[5:08] safely, and separated where possible.
[5:11] Use clean utensils and follow the
[5:13] business procedure when preparing
[5:14] allergen orders. The key message is
[5:17] peanuts, tree nuts, and sesame can
[5:20] appear in obvious and hidden places.
[5:23] Always check ingredients carefully and
[5:25] control cross contact.
[5:27] Welcome to lesson 2.4. Fish,
[5:29] crustaceians, and molllesks.
[5:32] Fish, crustaceians, and molllesks are
[5:34] three separate allergen categories, and
[5:36] food handlers must understand the
[5:38] difference. Fish includes foods such as
[5:41] cod, salmon, tuna, hadock, anchovies,
[5:44] and fishbased ingredients.
[5:47] Fish may be found in fish sauces,
[5:49] worstersha sauce, Caesar dressing,
[5:51] stock, curry pastes, pates, seafood
[5:54] dishes, and some flavorings.
[5:56] Crustaceans include prawns, crab,
[5:59] lobster, crayfish, and shrimp.
[6:02] These are common in seafood dishes,
[6:04] curries, noodles, soups, sauces, buffet
[6:07] foods, and mixed starters.
[6:10] Mollisks include muscles, clams,
[6:12] oysters, scolops, squid, octopus,
[6:15] cockals, welks, and snails.
[6:18] These may appear in seafood dishes,
[6:20] pyella, pasta, stews, sauces, and some
[6:23] specialist dishes. A customer may be
[6:26] allergic to one type of seafood and not
[6:28] another. So staff should not group
[6:30] everything together casually. Always
[6:32] check the exact ingredient and allergen
[6:34] information. Cross contact can also
[6:37] happen easily. For example, using the
[6:40] same fryer for breaded fish and chips
[6:42] may affect customers with fish or gluten
[6:44] concerns.
[6:46] Using the same grill, tongs or chopping
[6:48] board for prawns and other food can
[6:50] transfer crustation allergen. Fish and
[6:53] seafood ingredients can also be hidden
[6:55] in sauces and pastes, especially in some
[6:57] Asian style, Mediterranean, or prepared
[6:59] foods. As a level two food handler, you
[7:03] must check labels, recipes, supplier
[7:05] information, and preparation methods
[7:07] before answering. You must also
[7:10] communicate clearly with the kitchen.
[7:12] The key messages, fish, crustaceians,
[7:15] and molllesks are separate allergens.
[7:18] Check carefully, avoid assumptions, and
[7:20] control cross contact.
[7:23] Welcome to lesson 2.5. Soya, mustard,
[7:26] celery, and lupin. Soya, mustard,
[7:30] celery, and lupin are allergens that can
[7:32] be easy to miss because they are often
[7:33] used as ingredients inside other
[7:35] products.
[7:37] Soya may be found in soy sauce, tofu,
[7:40] soya milk, meat substitutes, sauces,
[7:43] marinades, desserts, chocolate, bread
[7:45] products, and some processed foods. It
[7:48] may also appear as soy flour, soya
[7:51] protein, textured vegetable protein, or
[7:53] lessin.
[7:54] Mustard may be found in mustard sauce,
[7:57] dressings, marinades, mayonnaise, spice
[8:00] mixes, chutneys, pickles, sauces, and
[8:03] ready-made meals. It may be listed as
[8:06] mustard powder, mustard seed or mustard
[8:08] oil. Celery may be found in soups,
[8:11] stocks, sauces, salads, seasoning mixes,
[8:15] stuffing, ready meals, buons and
[8:17] vegetable bases.
[8:19] It may appear as celery stalk, celery
[8:21] seed, celery salt or celery.
[8:25] Lupin is less common but still
[8:26] important. It may be found in some
[8:29] breads, pastries, pasta, gluten-free
[8:32] products, flowers, and baked goods. For
[8:35] example, a soup may not visibly contain
[8:38] celery, but the stock powder may contain
[8:40] celery salt. A sauce may not taste
[8:43] strongly of mustard, but mustard powder
[8:45] may be part of the seasoning blend.
[8:47] These allergens show why guessing is
[8:49] dangerous.
[8:51] Staff should not rely on taste,
[8:53] appearance, or memory. ingredients,
[8:56] labels, recipes, and allergen records
[8:58] must be checked. As a level two food
[9:01] handler, report any supplier or
[9:03] ingredient changes because allergen
[9:05] information may need updating. The key
[9:08] message is soya, mustard, celery, and
[9:10] looping can be hidden in prepared
[9:12] ingredients. So, always check before
[9:14] giving allergen information.
[9:16] Welcome to lesson 2.6. Sulfur dioxide
[9:19] and sulfites.
[9:21] Sulfur dioxide and sulfites are
[9:23] regulated allergens when they are
[9:25] present above certain levels. They are
[9:27] often used as preservatives in food and
[9:29] drink. Sulfites may be found in dried
[9:32] fruit, wine, cider, beer, bottled lemon
[9:35] or lime juice, pickled foods, some
[9:38] sauces, vinegar products, prepared
[9:40] potatoes, prawns, sausages, and some
[9:43] processed foods. This allergen can be
[9:46] easy for staff to overlook because
[9:48] sulfites may not always be visible in
[9:50] the finished dish. They may be inside a
[9:52] preserved ingredient, drink, source, or
[9:55] prepared product. For example, a salad
[9:58] may include dried apricots or raisins
[10:00] that contain sulfites.
[10:03] A sauce may include wine or bottled
[10:05] lemon juice. A prepared potato product
[10:08] may contain sulfites to prevent
[10:10] browning.
[10:11] Some people are sensitive to sulfites
[10:13] and reactions can include breathing
[10:15] difficulties, especially for people with
[10:17] asthma. This is why sulfite information
[10:20] must be checked properly when customers
[10:22] ask. As with all allergens, staff should
[10:25] not guess. Check the label, supplier
[10:28] information, allergen matrix, or recipe.
[10:32] If a dish uses bottled, dried, pickled,
[10:34] or preserved ingredients, pay extra
[10:36] attention because sulfites may be
[10:38] present. Cross contact may also happen
[10:41] if shared utensils or containers are
[10:43] used carelessly. Although the main risk
[10:45] is usually the ingredient itself, the
[10:48] key message is sulfites are often hidden
[10:50] in preserved foods and drinks. They may
[10:53] not be obvious, so always check
[10:55] ingredients and supplier information
[10:57] before answering customers.
[10:59] Welcome to lesson 2.7. Hidden allergens
[11:02] in common ingredients.
[11:04] Hidden allergens are allergens that may
[11:06] not be obvious from the name,
[11:08] appearance, or taste of a food. This is
[11:10] one of the biggest risks in allergen
[11:12] safety because staff may assume a food
[11:14] is safe when it actually contains an
[11:16] allergen inside an ingredient, source,
[11:18] seasoning, or bought in product. For
[11:21] example, a curry sauce may contain milk,
[11:24] mustard, celery, nuts, or soy. A soup
[11:27] may contain wheat flour, milk, celery,
[11:30] or fish stock. A burger bun may contain
[11:33] sesame, milk or egg. A dressing may
[11:37] contain mustard, egg, fish, or sulfites.
[11:40] A dessert may contain nuts, milk, egg,
[11:43] gluten, or soya. Allergens may also be
[11:46] hidden in stock cubes, spice mixes,
[11:49] marinades, gravy powders, breadcrumbs,
[11:52] battered foods, chocolate, flavorings,
[11:55] vegan products, gluten-free products,
[11:57] and ready-made sauces.
[11:59] This is why staff must check product
[12:01] labels and supplier information,
[12:03] especially when ingredients change. A
[12:06] new supplier may use a different recipe.
[12:09] A product may look the same but contain
[12:11] different allergens.
[12:13] For example, a cafe may change to a
[12:15] cheaper mayonnaise.
[12:17] The old one may have been egg-free, but
[12:19] the new one contains egg. If staff do
[12:22] not update the allergen information,
[12:24] customers may be given the wrong advice.
[12:27] As a level two food handler, never rely
[12:29] only on memory. Check current
[12:31] information, follow the allergen
[12:33] procedure, and report changes
[12:35] immediately. The key message is simple.
[12:38] Allergens are not always obvious. Hidden
[12:41] allergens are controlled by accurate
[12:43] information, clear labels, updated
[12:45] records, and careful communication.
