About Mustard Allergies

Mustard allergies are the fourth most prevalent allergy in children behind egg, peanut, and milk allergies. Allergies to mustard seeds can be severe, and can cause Anaphylaxis, the life-threatening allergic reaction that can affect multiple systems in the body, including the cardiovascular system, the respiratory tract, the skin and the gastrointestinal tract.

The processed foods which can contain the mustard seed ingredients are pickled gherkins, and small white onions. Various spicy sauces, vinaigrettes, mayonnaises often contain mustard condiment. Specific items that are especially problematic are hotdogs, lunch meat, pickles, barbeque sauce, and seasoning mixes (shake and bakes, etc).

Mustard is also used as an ingredient in many ready-cooked dishes, fritters, crackers, appetizers, various flours marketed for pizzas, fritters & dehydrated products for soups. Mustard is even present in baby food. It is a contaminant of hot-dogs (even without mustard), simply because of the salesmen’s handling them. The risk of contamination cannot be excluded for fast food restaurants.

The major allergens in mustard seeds are heat resistant so cooking does not make it any safer. Those with multiple food allergies should be particularly careful before they start using any new ingredient including mustard seeds. France has the highest incidence of mustard seed allergy. The European Union and recently Canada has recognized sesame and mustard seeds as major allergens. In the US, statistics is not available for mustard seed allergies because it is relatively rare but not unheard of. Hence, there has been a push towards including sesame seeds and mustard seeds in the list of top food allergens.

Testimonial from Jonna E. Licata

Gerbs Sunflower Meal. We own a small bakery and have used this in one of our breads that normally calls for almond flour. It has a pleasant sunflower seed taste and is GF and nut-free! I used it cup for cup as an almond meal substitute. Highly recommend!
