Subway
Subway is a sandwich chain whose U.S. website publishes an allergen information page covering new and test products alongside its standard allergen information. The page lists allergen content for items such as cookies, chicken tenders, and macaroni and cheese, and asks guests to notify the sandwich artist about a food allergy or sensitivity before ordering. It also states that breads and other items prepared in the restaurant may come in contact with items containing egg, fish, dairy, peanut, sesame, shellfish, soy, tree nuts, wheat, and sulfites.

Good to know before you book
- Subway states that breads and other items prepared in its restaurants may come in contact with items containing egg, fish, dairy, peanut, sesame, shellfish, soy, tree nuts, wheat, and/or sulfites. — Subway allergen information page (subway.com), 2026-10-28
- Recovered retry chain (dataset-notes gap #2). Source is an allergen statement and new-products page rather than a full item-by-item matrix, so format is web-page with itemByItem false. No separate gluten charting on the page, so gluten is not included in allergensAddressed. — Subway allergen information page (subway.com), 2026-10-28
Questions diners ask about Subway
Does Subway publish an allergen menu or matrix?
Yes — Subway publishes allergen material in web-page form, linked from this page and last checked on 2026-10-28. It addresses 9 of the 10 allergens we track.
Which allergens does Subway's published material not cover?
It does not address: Gluten. Not addressed means the chain's document is silent on that allergen — not that the allergen is absent from the food.
If Subway publishes a protocol, does every location follow it the same way?
A chain document is a ceiling, not a location guarantee. Locations vary in staff, equipment and practice, so a location listing on this site carries its own tier and its own last-checked date, and the questions on the visit-prep card are the ones to ask at the location you are visiting.
What does Subway itself say about cross-contact?
Subway states that breads and other items prepared in its restaurants may come in contact with items containing egg, fish, dairy, peanut, sesame, shellfish, soy, tree nuts, wheat, and/or sulfites.

Questions to ask at your location
- Is the fryer shared with breaded or battered items, and what else is cooked in that oil?
- Is there a separate prep area, boards and utensils for allergy orders?
- How are staff trained on food allergies, and how often is that training refreshed?
- Which parts of the kitchen, if any, are kept free of my allergen?
- Does this location follow the chain's published allergen procedure, and who here is trained on it?
ConfidentDiner collects allergen and preparation information from restaurants’ published materials, from restaurants themselves, and from diners. Information is dated and sourced, but menus, ingredients, suppliers, staff, and kitchen practices change without notice, and cross-contact can occur in any non-dedicated kitchen. Nothing on this site is medical advice or a guarantee that any restaurant or dish is safe for any individual. Always tell the restaurant about your allergy, confirm current practices directly before ordering, and make your own decision with your medical professional’s guidance.
