The 14 EU allergens: what must be declared on labels — and what doesn't have to be

EU food law does something genuinely useful for allergic consumers that many shoppers don't know is law: Regulation (EU) No 1169/2011 (the “FIC” regulation) defines 14 substances that must be declared and visually emphasised — bold, capitals, or underline — inside the ingredient list of every prepacked food, every time they or their derivatives are used.

The 14, with their hiding places

AllergenEasy to miss as
Cereals containing gluten (wheat, rye, barley, oats, spelt, kamut)malt extract, couscous, semolina, seitan
Crustaceansshrimp paste in Asian sauces
Eggslysozyme (in some cheeses), albumin, some wine finings
FishWorcestershire sauce (anchovy), some wine/beer finings, surimi
Peanutsgroundnut oil, satay, some 'vegetable' protein
Soybeanslecithin (E322 from soy), tofu, edamame, miso
Milkcasein, whey, lactose carriers in crisps and processed meat
Tree nuts (almond, hazelnut, walnut, cashew, pecan, brazil, pistachio, macadamia)marzipan, praline, pesto, nut oils
Celeryceleriac, spice mixes, stock cubes
Mustardcurry, mayonnaise, salad dressings, pickles
Sesame seedstahini, hummus, gomashio, some burger buns
Sulphur dioxide & sulphites (>10 mg/kg)dried fruit, wine, vinegar, processed potatoes
Lupinlupin flour in gluten-free and high-protein baking
Molluscsoyster sauce, squid ink, scallop powder in seasonings
The emphasis requirement applies to derivativestoo — a label can't hide milk behind “casein” in plain type. If a product has no ingredient list at all (some alcoholic drinks), allergens must still be declared with a “contains” statement.

Where the protection stops

Allergens hiding in additives

Some E-numbers are themselves allergen-derived or allergen-relevant: soy lecithin (E322) keeps its soy emphasis duty, egg lysozyme (E1105) appears in some cheeses and wines, and the sulphite preservative group (E220–E228) is the reason “contains sulphites” is printed on wine. The additive index notes the function of each; the per-product allergen call always belongs to the printed label.

How Forkin handles allergens

Set your allergens once in the app and every scanned product is checked against its enriched, per-market ingredient data — including the derived allergen tags on each product and, where available, per-country recipe variants of the same barcode. Menu scanning applies the same check to restaurant dishes, and the meal planner's starter plans swap out recipes that hit your registered allergens.

Hard limit, stated plainly: Forkin is an information tool, not a medical device. Databases can lag a reformulation, and cross-contamination is invisible to any database. Always read the label, and for severe allergies follow your clinician's guidance over any app, including ours.

A practical shopping checklist

Frequently asked questions

Is 'may contain traces of…' regulated in the EU?
Mostly no — precautionary 'may contain' statements are voluntary and unstandardised. The absence of a 'may contain' line does not mean the absence of cross-contamination risk, and its presence doesn't quantify the risk. Only the emphasised allergens in the ingredient list itself are legally mandated.
Are sulphites really an allergen?
Sulphites (E220–E228) trigger intolerance reactions rather than classic IgE allergy in most affected people, but EU law treats them as a mandatory declaration above 10 mg/kg or 10 mg/L — which is why 'contains sulphites' appears on wine, dried fruit and many condiments.
What's the difference between milk allergy and lactose intolerance on a label?
Milk allergy reacts to milk proteins (casein, whey) — tiny amounts matter, and 'milk' must be emphasised in the ingredient list. Lactose intolerance is about the sugar, and many high-lactose products are safe for milk-allergic people only if protein-free, which labels rarely clarify. Treat 'lactose-free' as irrelevant to a milk allergy.
Can I rely on an app instead of reading the label?
No. Forkin surfaces allergen data per product and flags your registered allergens, but recipes change, factories change, and database entries can lag a reformulation. For medically significant allergies, the printed label and your clinician's advice always win. Always read the label.
