Mustard Allergy

People with mustard seed protein allergies should be careful when consuming the seeds and sprouted seeds from plants in the Brassicaceae family. This includes broccoli, cauliflower, cabbage, Brussel sprouts, turnip and rapeseed.

Food containing mustard or canola meal or protein as an ingredient should not be consumed by people with mustard allergy. Canola oil can be made using both rapeseed (Brassica Napus and Brassica Rapa) and mustard seed (Brassica Juncea), but is highly refined and does not contain any appreciable amounts of protein, so it does not pose a risk for people with mustard allergy.
