I have a mustard allergy—is this oil safe for me?

This oil is produced from mustard seeds and consists of 100% mustard oil with no other ingredients. Even though it is an oil rather than whole seeds, it can still contain trace proteins and compounds from mustard that provoke allergic reactions in sensitive individuals. Mustard is one of the fourteen major allergens recognized in EU food law, and reactions can range from mild oral itching to serious systemic responses.

If you know you react to mustard—whether from condiments, seeds, or mustard greens—do not use this product. Cross-reactivity is also possible if you are allergic to other plants in the Brassicaceae family, such as rapeseed or certain vegetables, so check with your doctor if you are uncertain. There is no safe workaround: heating or diluting the oil does not remove allergens. Choose a different culinary oil without mustard content, such as sunflower, olive, or linseed oil, depending on the flavor profile you want.
