Mustard allergy is a reaction to proteins found in mustard seeds and mustard-based products. It is one of the 14 declared allergens in the UK. Mustard can cause reactions ranging from skin irritation to anaphylaxis. A mustard allergy card helps you stay safe in restaurants and food settings where mustard is widely used.

Where Mustard Hides in Food

Mustard appears in salad dressings, marinades, barbecue sauces, pickles, and many curry powders. It is used as an emulsifier in processed foods and can be found in mayonnaise, sausages, and ready meals. Mustard seeds and mustard oil are staples in Indian cooking. Even small amounts in a spice blend can trigger a reaction.

How a Mustard Allergy Card Protects You

Mustard allergy is less well-known than nut or dairy allergies, so some food handlers may not think to check for it. A card that explicitly lists mustard as your allergen ensures it is not overlooked. It is especially valuable in restaurants that use house-made sauces and dressings where mustard is a key but unlisted ingredient.

When to Use Your Mustard Allergy Card

Carry your card at restaurants, particularly Indian, French, and American-style diners where mustard is a common ingredient. Barbecue joints, delis, and sandwich shops also rely heavily on mustard-based condiments. When travelling, a translated card helps navigate cuisines where mustard may be used without being highlighted.
