Food Allergies in Switzerland:
Fondue, Rösti, and Which Card to Carry

Switzerland's allergen rules: what to expect

Switzerland is not a European Union member state, but its food law, specifically the Food Information Ordinance (Verordnung betreffend die Information über Lebensmittel, LIV), enforced by the Federal Food Safety and Veterinary Office (FSVO/BLV), closely mirrors the EU's own allergen framework. The same 14 major allergens have to be declared, and on packaged food they must be visually emphasized in the ingredient list, in bold, underlined, or capitalized, so they stand out from the rest of the ingredients rather than sitting buried in a long list.

For unpackaged food, restaurants, bakeries, and butcher counters, the requirement is real but noticeably looser than the written-information expectation many EU countries have built up. Swiss law has required allergen information for non-prepacked food since 2017, but a staff member who knows the information is legally allowed to give it verbally rather than produce anything in writing. A peer-reviewed 2021 survey of Swiss food businesses found that 86% provide only oral allergen information, just 14% offer anything written upfront or on request, and nearly 40% don't even post a notice telling customers how to ask in the first place. A written allergy card doesn't just help the conversation here, it fills a real gap in what the venue is otherwise obligated to hand you.

Hidden allergens in Swiss cuisine

Dairy: nearly unavoidable in a fondue, raclette, or rösti

Traditional Swiss cooking is built around cheese. Fondue is melted cheese (usually a Gruyère and Vacherin blend) with white wine and a splash of kirsch. Raclette is cheese scraped directly onto the plate, alongside potatoes, pickled onions, and charcuterie. Rösti, the potato dish that shows up alongside almost everything, is traditionally just potato and butter or lard, but restaurant and diner versions frequently stir in cheese or bacon fat. Zürcher Geschnetzeltes, sliced veal and mushrooms in a cream sauce, adds dairy from a completely different direction. Ask about the cheese, the butter, and the sauce separately, since a dish can look dairy-free on the menu description and still involve all three.

Gluten in fondue's bread, rösti additions, and Älplermagronen

The bread cubes served alongside fondue for dipping are the actual gluten source in that dish, not the cheese itself, and some fondue recipes also use a small amount of flour or cornstarch to thicken the mixture, which is worth asking about specifically rather than assuming. Älplermagronen, Alpine macaroni and cheese layered with potato and cream and traditionally served with apple sauce, is wheat pasta by definition and not adaptable. Rösti itself can be naturally gluten-free since it's just grated potato, but ask about a shared fryer or pan and whether any flour binder has been added.

Tree nuts in Swiss chocolate and Basler Läckerli

Switzerland's chocolate industry uses hazelnuts and almonds heavily: praline fillings, gianduja-style spreads, and nougat centers all routinely use ground nuts, and Toblerone's distinctive nougat is made with honey and almonds specifically. Basler Läckerli, a spiced honey biscuit with candied citrus peel that's a common gift-shop item, traditionally includes almonds or hazelnuts in the dough itself. Birchermüesli, the oat, fruit, and dairy breakfast that can look like the safe option on a menu, typically combines oats (gluten), dairy (yogurt or cream), and nuts in the same bowl, so it's worth checking the exact recipe rather than assuming from the name.

Key German, French, and Italian phrases for allergy communication

Which language actually matters depends on where you're eating: German across Zurich, Bern, Basel, and most of the country; French in Geneva, Lausanne, and the rest of Suisse Romande; Italian in Ticino, around Lugano and Bellinzona. A card is useful, but ask the staff member who will confirm your order to read it back to you.

• Ich habe eine Lebensmittelallergie gegen [allergen] / J'ai une allergie alimentaire à [allergen] / Ho un'allergia alimentare a [allergen] (I have a food allergy to [allergen])
• Ich bin allergisch gegen [allergen] / Je suis allergique à [allergen] / Sono allergico/a a [allergen] (I am allergic to [allergen])
• Enthält dieses Gericht [allergen]? / Ce plat contient-il [allergen] ? / Questo piatto contiene [allergen]? (Does this dish contain [allergen]?)
• Ist das Brot glutenfrei? / Le pain est-il sans gluten ? / Il pane è senza glutine? (Is the bread gluten-free?)
• Diese Allergie kann lebensbedrohlich sein / Cette allergie peut être mortelle / Questa allergia può essere pericolosa per la vita (This allergy can be life-threatening)
• Ich brauche einen Arzt, rufen Sie 144 / J'ai besoin d'un médecin, appelez le 144 / Ho bisogno di un medico, chiamate il 144 (I need a doctor, call 144)

Swiss dishes that need closer checking

Choosing where to eat, and which supermarket to trust

Migros and Coop both operate nationwide with dedicated free-from ranges: aha! at Migros, produced at Switzerland's largest gluten-free production facility and certified by the Swiss Allergy Centre, and Free From at Coop, running since 2006 with color-coded allergen labeling. Both meet Switzerland's own legal gluten-free threshold. Given how much of the restaurant system leans on verbal allergen information rather than a written chart, a supermarket meal is often the more verifiable option for a first day, a cautious meal, or a stretch outside the largest cities.

When eating out, ask specifically for the staff member who's informed about allergens, this is the actual legal mechanism Swiss restaurants use, rather than assuming the first person who takes your order has the information memorized.

German, French, or Italian: which card actually matters

Switzerland has three main-use official languages: German, spoken by roughly 62% of the population and dominant in Zurich, Bern, Basel, and most of the country; French, spoken by about 23%, across Geneva, Lausanne, and the rest of Suisse Romande; and Italian, spoken by about 8%, in Ticino around Lugano and Bellinzona. AllergyPass's Switzerland card defaults to German and English, matching where the largest share of the population and the largest cities sit. A dedicated French card covers Geneva, Lausanne, and the rest of Suisse Romande directly.

There isn't currently a dedicated Italian-Switzerland card. Travelers heading to Ticino can still select Italian as their own reading language under the builder's "My language" picker, which pairs it alongside the destination language on the same card, though the side the kitchen actually reads will still show German or French rather than Italian.
