Eating out with a sesame allergy in the UK

Published 29 October 2026

Eating out with a sesame allergy in the UK means naming sesame and getting an answer about that dish. Sesame is one of the 14 allergens a food business must tell you about when it is an ingredient. Annex II lists “sesame seeds and products thereof”. GOV.UK includes sesame in that list of 14. The Food Standards Agency’s consumer advice, for England, Northern Ireland and Wales, says businesses must tell you if they use any of the 14 as ingredients. The technical guidance, for England, Wales and Northern Ireland, says sesame covers seeds, ground sesame powder and sesame oil, and that tahini must refer to sesame, for example “tahini (sesame)”. One or two sesame seeds is its example of a tiny amount that can affect someone sensitive to that food. This page does not replace your allergy action plan or the NHS.

Where sesame turns up

The Food Standards Agency’s allergen entry for sesame says these seeds can often be found in bread, sprinkled on hamburger buns for example, in breadsticks, houmous, sesame oil and tahini, and are sometimes toasted and used in salads. Anaphylaxis UK’s sesame factsheet, published as Allergy UK incorporating Anaphylaxis UK, says hummus is usually made with tahini, so ask about that dip. It calls tahini a paste used in Middle Eastern cooking, and names halvah, sesame snaps and bars, gomashio and furikake. Foods it says are sometimes made with sesame include veggie burgers, crackers, biscuits, burger buns, bagels, some breads, stir-fry oils and vegetables, salad dishes and baklava (spelt backlava on the factsheet). South Asian, Middle Eastern, Mediterranean and Caribbean cooking are on that “sometimes” list.

Seeds can be black, white, brown or red. Other names include benne, gingelly and gingelly oil, sim sim, til and Sesamum indicum. Say sesame as well. The factsheet says avoid sesame oil as well as the seeds, because the oil is usually unrefined and contains the proteins that trigger reactions. Your specialist decides if an oil is a problem for you. The kitchen says which oil is in the pan. The best-practice note, for England, Northern Ireland and Wales, shows a barbecue chicken burger whose bap lists wheat, eggs and sesame. See the sesame allergy guide and the 14 allergens UK restaurants must declare.

What to ask the staff

The consumer advice says check the menu or call ahead. Be clear, and give examples: sesame seeds, tahini, houmous or hummus, sesame oil, a seeded bun. Ask if they offer a suitable meal or can make one, how food is handled, whether equipment or ingredients could cross-contaminate, and whether the recipe changed. They must give allergen information. They do not have to cook a different meal. If you doubt they understand, do not eat there. On arrival, say it again, and mention glazes, garnishes, sauces and cooking oils. The NHS says tell restaurant and café staff, and know the ingredients before you eat. The longer script is how to tell a restaurant about your food allergy.

In Scotland, Food Standards Scotland sets out that same conversation. A takeaway needs allergen information when you order and when it arrives. Anaphylaxis UK says restaurants, cafes, hotels, takeaways and other catering businesses must tell you about major allergens, including sesame. Ask staff to check with the chef.

• Is there sesame seed, tahini, houmous, hummus or sesame oil in the dish, sauce, garnish or bread?
• Are there seeds on the bun, or inside the dough?
• Which oil is in the pan, and what else was cooked in it?
• What else used this fryer, board or counter?
• What changed today, and what did the kitchen say?

The factsheet says some people with a sesame allergy also react to other seeds, peanuts or tree nuts, and that you may still be able to eat those. Ask your GP or specialist before you change what you avoid. The peanut, tree nut and gluten guides are separate questions.

Cross-contact, fryers and surfaces

The precautionary allergen labelling guidance, for England, Northern Ireland and Wales, describes cross-contact as traces getting into food by accident: food touching or dripping, shared boards and utensils, and a shared fryer. One example is sesame rolls kept apart from plain rolls. The factsheet says take extra care with loose bread at a deli or in-store bakery. Seeds can be in the dough, move from other loaves, and cling to surfaces. Heating does not destroy the part of sesame that causes allergies, and kitchen temperatures do not remove that risk.

“May contain” labels

A “may contain” line means an allergen may be present because of cross-contamination. The consumer advice says there is no specific legal requirement to print it. The guidance says a business should use one only when a risk assessment finds a risk that cannot be removed, and that “may contain allergens” could be misleading. Ask which allergen is meant. The factsheet says if a product says “may contain sesame”, it is best to avoid that food. Your specialist decides how that applies to you. If there is no line, still ask. See “may contain” labels.

Natasha’s Law and food packed before you choose it

Prepacked for direct sale food is packed before you choose it, by the same business. The Food Standards Agency calls these rules Natasha’s Law. The technical guidance says they took effect in all four UK nations on 1 October 2021. The pack needs the food’s name and a full ingredients list, with allergens emphasised. The label should not replace a conversation. Natasha’s Law and PPDS labelling is the longer account.

GOV.UK separates a restaurant meal, a takeaway, and PPDS food such as a boxed sandwich or a burger wrapped before you buy it. Read the list for sesame. A plate cooked to order still needs allergen information, written or spoken, with a signpost if it is spoken. A takeaway must tell you before you buy and again at delivery. Ask for the container to be labelled. Ordering a takeaway with a food allergy covers that timing.

A search starts the question

A search for sesame allergy restaurants chooses where to ask. It does not clear a kitchen. You can search for restaurants for a food allergy and search on the SafePlate homepage. Searching SafePlate is free. Record sesame on its own. London, Bristol and Manchester say who covers food businesses locally. The allergy-friendly restaurant guides collect those pages.

The usable allergy chef card, in 38 languages, is part of SafePlate Plus. The allergy chef card page is a preview. On the free site you see that preview only. It is not filled in with your foods, and you cannot hand it over or print it as your card.

If a reaction starts

If you think you might have a sesame allergy, Anaphylaxis UK says speak to your GP. The NHS says see a GP if you think you or your child may have a food allergy, and not to cut foods out without speaking to a GP. A specialist gives you an allergy action plan. Follow that plan. The factsheet says carry two in-date adrenaline devices if they were prescribed.

In a reaction, follow that plan and the NHS. The food allergy page says call 999 if the lips, mouth, throat or tongue suddenly swell, if breathing is very fast or a struggle, if the throat feels tight or swallowing is hard, if the skin, tongue or lips turn blue, grey or pale (on black or brown skin, check the palms or soles), if someone becomes confused, drowsy or dizzy, if someone faints and cannot be woken, or if a child is limp, floppy or not responding as usual. Do not drive to A&E. If they have an adrenaline auto-injector, such as an EpiPen, or a nasal spray (EURneffy), use it immediately, then call 999 even if they seem better.

The anaphylaxis page says say anaphylaxis, lie down, and use a second auto-injector if there is no improvement after 5 minutes. Do not stand or walk. You can raise the legs, or sit up slowly if breathing is hard. If they are pregnant, lie on the left side. Food Standards Scotland points people in Scotland to NHS Inform. If this and the NHS differ, follow the NHS and the plan. The meal steps are in what to do in an allergic reaction.

Set up your foods before you search. This is not medical advice. Confirm the meal with the kitchen. In the UK, if you think someone is having anaphylaxis, call 999.
