Food Allergies in Portugal:
Seafood, Sulphites, and EU Law in Practice

EU allergen law in Portugal

Portugal is an EU member state and follows the Food Information to Consumers (FIC) Regulation, which mandates that restaurants and food businesses provide information on 14 designated allergens when asked. These allergens must also be highlighted in bold on packaged food ingredient lists.

The 14 mandatory EU allergens are: cereals containing gluten (wheat, rye, barley, oats, spelt), crustaceans, eggs, fish, peanuts, soybeans, milk and dairy, tree nuts (almonds, hazelnuts, walnuts, cashews, pecans, Brazil nuts, pistachios, macadamia), celery, mustard, sesame, sulphur dioxide and sulphites (above 10mg/kg or 10mg/litre), lupin, and molluscs.

Restaurants are not required to print allergen information on menus, but must be able to provide it verbally or in a written document on request. Compliance quality varies significantly across restaurant types. High-end restaurants in Lisbon and Porto tend to have consistent processes; smaller tascas and family-run restaurants may have less structured systems, though staff are often willing to help if asked clearly.

Hidden allergens in Portuguese cuisine

Fish: the most embedded allergen in Portuguese cooking

Fish is the defining allergen risk in Portugal. Bacalhau (dried and salted cod) is Portugal's national ingredient, reportedly prepared in over 365 different ways. It appears in croquettes (pasteis de bacalhau), in rice dishes (arroz de bacalhau), in soups, in stews, in gratin preparations (bacalhau com natas), and as a staple at nearly every traditional restaurant. For travelers with fish allergy, Portugal requires constant vigilance.

Beyond bacalhau, grilled fish (peixe grelhado) is the standard everyday meal in coastal regions. Fish stocks are used as the base for many soups, rice dishes, and sauces. Caldeirada (fish stew) and caldo verde (which sometimes includes cod) are traditional dishes where fish presence may not be obvious from the name. Even at restaurants focused on meat, fish-based stocks may be used in kitchen preparations.

Shellfish: in rice, stocks, and coastal menus

Shellfish (marisco) forms a major category of Portuguese cuisine, particularly in coastal cities and the Algarve. Amêijoas (clams), gambas (prawns), camaroes (shrimp), percebes (barnacles), and lagosta (lobster) feature prominently. The hidden risk is in cataplana (a shellfish and pork stew often served with rice), arroz de marisco (shellfish rice), and in many restaurant stocks used as base preparations.

Cross-contamination risk at coastal seafood restaurants is high. Grills, preparation surfaces, and cooking oils are often shared between shellfish and non-shellfish dishes. For severe shellfish allergy, choosing inland restaurants with limited seafood focus is the safer strategy.

Sulphites: in virtually all Portuguese wine

Portugal has a significant and growing wine industry, and sulphites (sulfur dioxide, SO2) are used as a preservative in almost all commercial wine production. EU law requires wines containing sulphites above 10mg/litre to declare them on the label, which means the vast majority of Portuguese wine bottles carry this declaration. This includes Vinho Verde, Alentejo reds, port wine, and most table wines.

For travelers with sulphite sensitivity or allergy, this extends beyond wine to some dried fruits, preserved fish products (including some bacalhau preparations), and certain vinegar-based condiments common in Portuguese cooking. The EU sulphite threshold is low enough that most commercial wines will trigger it.

Wheat and eggs: in pastries and iconic dishes

Wheat (trigo) is the base of Portugal's rich pastry culture. Pastel de nata (Portuguese custard tart), the country's most famous food export, contains wheat pastry, eggs, dairy cream, and milk in a single item. It is not safe for wheat, egg, or dairy allergy. Pao de Deus (sweet bread rolls), bolos (cakes), and most Portuguese pastry shop offerings contain wheat as a primary ingredient.

Eggs (ovos) are deeply embedded in Portuguese baking. Conventual sweets (doces conventuais): a category of traditional sweets originating from Portuguese convents : are almost universally made with large quantities of egg yolks and sugar. Ovos moles (soft eggs), bolo de mel (molasses cake), and toucinho do ceu (almond and egg cake) are examples. Portuguese dessert culture is one of the most egg-intensive in Europe.

Peanuts: in snacks and pastry fillings

Peanuts (amendoins) are more present in Portuguese snack culture than travelers often expect. Roasted and salted peanuts are a common bar snack. Peanut-based sweets and nougat appear in confectionery shops. Some regional pastry fillings use peanut alongside almond. The risk is lower than in some cuisines but still worth flagging, particularly at pastelarias (pastry shops) and snack counters where multiple nut types are handled together.

Cross-contamination between peanuts and tree nuts (particularly almonds and walnuts, both widely used in Portuguese regional desserts) is a real concern at pastry counters. Travelers with severe peanut allergy should flag both peanut and cross-contact risk explicitly.

Gluten and tree nuts in regional sweets

Almond (amêndoa) is a cornerstone of southern Portuguese and Algarve pastry. Marzipan-style sweets shaped as fruit (frutas de amêndoa), almond cakes (bolo de amêndoa), and various regional confections use almond flour heavily. For travelers with tree nut allergy, Algarve pastry shops are particularly high-risk environments.

Walnut (noz) appears in bolo de mel (Madeiran molasses cake) and several regional bread and cake recipes. Hazelnut features in chocolate confections and some pastry fillings. As with most European pastry environments, the risk of cross-contamination between different nut types at the same counter is significant.

Key Portuguese phrases for allergy communication

• Tenho alergia alimentar grave a [allergen]: I have a serious food allergy to [allergen]
• Sou alérgico/a a peixe: I am allergic to fish
• Sou alérgico/a a marisco: I am allergic to shellfish
• Sou alérgico/a a amendoins: I am allergic to peanuts
• Sou alérgico/a a gluten (trigo, centeio, cevada): I am allergic to gluten (wheat, rye, barley)

High-risk Portuguese dishes by allergen

Where allergy communication works best in Portugal

Modern restaurants in Lisbon and Porto: Both cities have a growing food scene with international-standard allergy awareness. Newer restaurants, particularly those with English-speaking staff, are more likely to have structured allergen processes. Call ahead for severe allergies at any restaurant.

Traditional tascas (family-run restaurants): These are Portugal's equivalent of neighborhood bistros. Staff are usually willing to help but allergen processes are informal. A written Portuguese-language card is particularly valuable here because it removes the language barrier and lets staff check directly with the kitchen.

Pastelarias (pastry shops): High cross-contamination risk for wheat, eggs, dairy, and tree nuts. Most items are made with multiple allergens. For severe single-allergen sensitivity, even individually safe-seeming items may be at risk from shared trays and utensils.

Supermarkets (Continente, Pingo Doce, Lidl): EU FIC labeling applies. All 14 mandatory allergens are highlighted in bold on packaged food labels. Portuguese supermarkets are a reliable and safe option for self-catering travelers.

Inland Portugal vs. coastal areas: Inland regions (Alentejo, Beiras) have somewhat lower seafood saturation than Lisbon, Porto, and the Algarve. Meat-focused dishes like porco alentejano (pork with clams, which still carries shellfish risk) and lamb are more common inland, reducing incidental fish exposure, though shellfish still appears in traditional recipes.

Frequently asked questions

Is Portugal safe for travelers with food allergies?

Portugal follows EU mandatory allergen law. Restaurants are legally required to disclose 14 allergens on request. The main practical challenge is that fish and shellfish are so embedded in Portuguese cuisine that cross-contamination risk is high at coastal restaurants and traditional tascas. A written Portuguese-language card and kitchen-level confirmation are essential for fish, shellfish, or severe allergies.

What are the biggest allergen risks in Portuguese food?

Fish (especially bacalhau, salt cod) is the highest-risk allergen. Shellfish is everywhere on coastal menus and in stocks. Sulphites are in virtually all Portuguese wine. Wheat and eggs are structural in pastries including pastel de nata. Peanuts appear in snacks and sweets more than most travelers expect.

Does pastel de nata contain allergens?

Yes. Pastel de nata contains wheat (pastry), eggs (custard), and dairy (cream and milk). It is not safe for wheat, egg, or dairy allergy. Cross-contamination risk at pastry counters is also high because multiple allergen-containing products are made in the same space.

How do you say food allergy in Portuguese?

Tenho alergia alimentar grave a [allergen]: I have a serious food allergy to [allergen]. For fish: Sou alérgico/a a peixe. For shellfish: Sou alérgico/a a marisco. For severity: Esta alergia pode ser fatal. A written card in Portuguese is more reliable than verbal communication in a busy restaurant.

Is bacalhau safe for fish allergy?

No. Bacalhau is dried salt cod and must be avoided by anyone with a fish allergy. It appears in croquettes, rice dishes, soups, stews, and gratins. The risk is compounded because bacalhau is so central to Portuguese cooking that even restaurants without seafood on the menu may use cod-based preparations in the kitchen.
