Sesame Allergy: Where It Hides and How to Spot It
Published 26 October 2026 · 6 min read
Sesame is one of the 14 allergens that must always be declared in the EU. You will find it in tahini, hummus, falafel, baguettes, rolls, Asian sauces and sesame oil. It is easy to miss, because it is often used as a topping or as a small part of a sauce or spice mix. With a sesame allergy, it is therefore worth asking not only about the main ingredient but also about the topping, the dressing and the oil.
What a sesame allergy is
A sesame allergy is an immune reaction to proteins in sesame seeds. It can cause reactions from mild (skin, digestive) to severe, so it should not be underestimated. The difference between allergy, intolerance and coeliac disease is explained in Allergy, intolerance and coeliac disease. Sesame is number 11 on the list of 14 allergens (the order most Slovak menus use, though you should check the legend). You can find the other allergens in The 14 EU food allergens.
Sesame has been a labelled allergen in the EU for a long time, so this is not a new requirement. It made the news mainly in connection with the USA, where it became the ninth major allergen under the FASTER Act, in force since 2023. This changes nothing for the EU, as it is an American rule.
Where sesame hides
Obvious and semi-obvious sources
- Tahini (sesame paste) is the base of hummus, baba ghanoush, halva and many dressings.
- Hummus and other chickpea spreads, often also falafel bowls or dip platters.
- Baked goods: baguettes, rolls, burger buns, bagels, grissini, bread rolls and crackers with a topping.
- Sesame bars and halva and other sesame sweets.
- Sesame oil, especially in Asian cooking.
Asian cuisine
- Sesame oil is added to sauces, marinades, noodles and fried dishes.
- Sesame seeds are sprinkled on sushi, rolls, wok dishes and salads (such as wakame).
- Sauces: teriyaki and some dressings in the style of Asian restaurants may contain sesame. The same goes for gomasio (sesame salt) and furikake (a rice topping).
- Noodles and rolls: cold sesame noodles, rice rolls or dumplings with a sesame filling.
Mediterranean and Middle Eastern cuisine
- Hummus, tahini and falafel.
- Za'atar, dukkah and similar spice blends often contain sesame.
- Pitta, flatbreads and bread sprinkled with sesame.
- Sweets: halva is made from sesame, and baklava may have a sesame topping or filling.
Unexpected places
Sesame can turn up in many "ordinary" foods: spice mixes, crisps and crackers, bread, vegan burgers, spreads and muesli bars. In a restaurant, ask about the topping and whether the bread is prepared and stored together with other bread.
How sesame is labelled
On prepacked food, sesame must be highlighted in the ingredients list. For non-prepacked food in a restaurant, allergen information is most often provided as numbers on the menu (sesame is usually number 11) or verbally, as described in Allergen numbers on menus. If the number is not available or you have doubts, do not rely on it and ask directly.
Sesame oil is one of the more problematic items: in the EU it does not have the exemption that applies to fully refined soybean oil, so it is listed as an allergen. Whether you can tolerate it is for your doctor to decide.
Risky situations in a restaurant
| Situation | Why it is risky |
|---|---|
| Sushi and Asian buffets | sesame in toppings, sauces and oil; shared utensils |
| Falafel, hummus, shawarma | tahini is the base of several sauces |
| Fast food | sesame buns that may be stored with others |
| Bakery and breakfast | bagels and topped bread, crumbs spread to other bread |
| Dressings and dips | tahini or sesame oil as an ingredient |
| Desserts | halva, sesame brittle, toppings |
With baguettes and rolls, seeds can also end up on bread that does not contain sesame. So even a "plain" roll from the basket can be affected by cross-contamination.
What to ask
- Is there sesame or tahini in this dish, including in the sauce, dressing, topping or oil?
- What is in the dip or spread? Hummus and tahini are the base, but other dips may contain it too.
- What was the food fried or prepared in? Sesame oil is used in Asian kitchens for flavouring.
- Can the bread be on the same tray as sesame bread?
- Can the topping be left off? Removing the topping is not enough, though, if the food has already touched the seeds.

What ordering looks like
A good approach is simple. First say that you are allergic to sesame, and ask for the allergen list for the dish you are interested in. Then ask about the sauce, dressing, topping and oil, because these are the items most often missed with allergies. With bread and baguettes, ask whether they are prepared on a separate surface. If the staff cannot answer or are unsure, it is sensible to swap the dish for something simpler, such as grilled meat or vegetables without a sauce, and check the oil and the surface it was cooked on again.
Ingredients in vegan cooking
Vegan and vegetarian dishes use tahini, hummus and seeds very often, because they replace animal fats and proteins. If you are looking for a plant-based menu, expect sesame to appear there more often than elsewhere. See also Vegan restaurants and Vegetarian restaurants, but remember that the "vegan" label does not guarantee that a dish is sesame-free.
Sesame and other allergies
Some people with a sesame allergy also react to other seeds or nuts, but this is not a rule. If you have several allergies, see also the article on peanut and tree nut allergy. An allergist should tell you exactly what to avoid.

Frequently asked questions
Is sesame a mandatory labelled allergen in the EU?
Yes. Sesame and products made from it are one of the 14 allergens under Regulation (EU) No 1169/2011, so they are declared on prepacked food and for non-prepacked food too. The American FASTER Act, in force since 2023, applies only in the USA.
Is there always sesame in hummus?
Traditional hummus contains tahini, which is sesame paste. There are recipes without tahini, but in a restaurant always ask what exactly it contains.
Does sesame oil contain sesame?
Sesame oil is made from sesame seeds and is listed as an allergen in the EU. Whether you can tolerate it is for your doctor to decide.
Is it enough to remove the sesame topping?
Not always. Seeds can get into the sauce, onto the bread or onto the utensils. With an allergy, removing the topping is not enough, and you should ask about the preparation too.
Which cuisines are riskiest?
Asian, Middle Eastern and Mediterranean cuisines use sesame most often, but you will also find it in bread and fast food. Ask in every kitchen.
