Mustard seeds are the small round seeds of mustard plants and are used as flavoring agents in a variety of foods.
Although mustard seed allergy is a fairly uncommon food allergy, it has been associated to conditions such as atopic dermatitis, and has cross-reactivity with mugwort pollen and the Brassica family of plants (cabbage, cauliflower, broccoli, Brussels sprouts, rapeseed, etc.). In addition, mustard seed allergy has been linked with sensitization to tree nuts, legumes, and the Rosaceae family of plants (apples, pears, apricots, plums, cherries, peaches, raspberries and strawberries), which can cause side effects in patients as severe as exercise-induced anaphylaxis.
Since rapeseed and mustard seed are used in the production of canola oil, it is suggested that those allergic to mustard seed should avoid canola oil as well.
