Allergen labels tell a clear story if you know how to read them, and in the EU, the rules behind those labels are among the strongest consumer protections in the global food system.
What the regulation actually requires
Regulation (EU) No 1169/2011 requires mandatory labelling for all foods of ingredients such as gluten-containing cereals, which have a scientifically proven allergenic or intolerance effect. This regulation is the foundation of everything you see on a food packet in Europe.
There are 14 allergens that must be clearly indicated if they are used as ingredients in food products sold in the EU. Allergens must be emphasised within the list of ingredients, for example, by using a different font, style, or background colour, to ensure they are easily identifiable by consumers. So when you scan a label, look first at the ingredient list, not the front of the pack.
If a cereal containing gluten is used as a deliberate ingredient, it must be listed in the ingredients list, no matter how much is used. When labelling foods, manufacturers must name the specific grain, for example wheat, rye, barley, oats, spelt, or khorasan wheat. This level of precision makes the EU system genuinely useful.
The threshold numbers you need to know
Two numbers drive safe gluten-free eating in Europe. The EU defines “gluten-free” through Commission Implementing Regulation (EU) No 828/2014, which sets strict thresholds: products labelled “gluten-free” must contain less than 20 parts per million (ppm) of gluten.
The optional term “very low gluten” may be used for products made from specially processed gluten-containing grains and must contain less than 100 ppm. In practice, most people with coeliac disease should stick to products that meet the 20 ppm standard. If a product says “gluten-free” on the label, you can generally trust that it meets this safety level across the EU.
These rules also apply to non-prepacked foods served in restaurants, cafés, or deli counters, where allergen information must be available in written form upon request.This information can be communicated verbally, but there must be clear indications on how consumers can obtain this information, and it must be available in written form upon request.
How to read allergen labels in practice
Start with the ingredient list on the back or side panel. In Europe, allergens including gluten must be clearly listed and highlighted on packaging, usually in bold or uppercase letters. This applies in every EU member state, regardless of language. Labels will say “sans gluten” (French), “sin gluten” (Spanish), “senza glutine” (Italian), “glutenfrei” (German), or “glutenvrij” (Dutch).
Learning the key words for wheat, barley, rye, oats, and spelt in local languages helps you identify gluten in ingredient lists. A simple reference card on your phone is enough. You do not need to read the full label in every language: look for the bold or capitalised text.
Third-party certification adds another layer of confidence. The gluten-free symbol, the crossed grain symbol, is recognised throughout Europe and is awarded according to the standard of the Association of European Coeliac Societies (AOECS). One trademark licence gives producers and retailers the right to use the Crossed Grain Trademark on their gluten-free sales in over 30 European countries. When you see this symbol, the product has passed an independent audit.
Expert perspective on precautionary labelling
The precautionary allergen label is the most misunderstood element of EU food labelling for gluten-free consumers. Phrases such as “may contain wheat” are entirely voluntary under current EU law. There is no standardised phrasing and no defined risk threshold that legally requires their use. One manufacturer uses such a phrase to signal a real and probable cross-contamination risk, while another uses it purely as a legal precaution when actual contamination is demonstrably low. A third may operate on shared equipment with no precautionary statement at all. Until the European Commission harmonises this area, consumers must treat every such statement as a genuine warning, look for manufacturers who specify actual contamination controls such as dedicated production lines and batch testing, and never assume that the absence of a precautionary statement means the absence of risk.

The cross-contamination gap
Under EU law, precautionary allergen statements are entirely voluntary. There is no standardised phrasing, no defined risk threshold that triggers their use, and no legal requirement to include them at all. This is the biggest practical gap in the current system.
The use of Precautionary Allergen Labelling (PAL), or a cross-contamination phrase, falls under voluntary food information. The starting point for using a PAL on a label is to warn consumers with allergies or intolerances of a real risk of contamination. This is cross-contamination that may enter the product despite preventive measures and hygiene regulations.
The European Commission is aware of this gap, and work is ongoing toward harmonising precautionary allergen labelling across member states. Progress is moving at the global level too. Experts from the FAO and WHO concluded that a reference dose of 4 mg of gluten per eating occasion should be used to determine whether a precautionary allergen label is needed. The reference dose serves as a scientific cutoff for regulators: if accidental gluten in a single serving of a food could exceed 4 mg, then a precautionary label should be required. This is a useful development for the market.
Allergen labels and the broader EU food agenda
The gluten-free food market in Europe is large and growing. Over 5 million Europeans live with coeliac disease requiring strict gluten-free diets. Applying a ratio of 1 in 100, it can be assumed that more than 7 million people are affected by coeliac disease across Europe, with only approximately 25% of those actually receiving a diagnosis. Better allergen labels help close that gap between undiagnosed consumers and safe food choices.
Proposed amendments to the FIC Regulation are exploring the use of QR codes and digital label formats that would allow consumers to access detailed production information, batch testing data, and allergen management documentation directly from their phones at the point of purchase. This connects directly to Europe’s broader digital and green economy agenda, where transparency and traceability are becoming competitive advantages, not just compliance requirements.
Producers who invest in robust labelling and certification today build consumer trust that lasts.
Read allergen labels with a clear strategy
Allergen labels in the EU give you real information, and you can use that information well. Look first at the ingredient list. Confirm the “gluten-free” claim meets the 20 ppm threshold. Check for the Crossed Grain certification symbol as an extra layer of trust. Treat any cross-contamination statement as a serious warning. Ask restaurant staff for written allergen information. Reading allergen labels correctly is not complicated: it takes 3 focused steps and a basic knowledge of the regulation. Use this approach every time, and safe gluten-free eating across Europe becomes straightforward.
