Mustard Seed

No. Both mustard seed powder and whole mustard seeds present a low risk when safely prepared for a child’s age and developmental ability, though, in theory, an individual could choke on any food. To reduce the risk, prepare and serve mustard seed in an age-appropriate way. As always, make sure you create a safe eating environment and stay within an arm’s reach of baby during meals.

No, mustard seed is not considered a common allergen worldwide (nor in the United States). However, mustard seed is designated as an allergen of regional importance in Canada, Europe (including the UK), the Gulf States, and a number of Asian countries including Bangladesh, Kazakhstan, and Russia. In fact, mustard is considered the 4th most common food allergen in France, where it is a common ingredient in cooking. Note that certain spice blends that feature mustard seed may also contain other common food allergens, so make sure to read labels thoroughly. Mustard allergy has been reported to result in a variety of allergic reactions, ranging from rashes to respiratory and severe life-threatening reactions (anaphylaxis).

Mustard seed is a part of the cruciferous vegetable family and individuals who are allergic or sensitive to other members of the cruciferous family, such as kale and broccoli, could theoretically be sensitive to mustard seed as well. Individuals with Oral Allergy Syndrome (also known as pollen food allergy syndrome), and in particular, those with sensitivities to mugwort pollen, may also be sensitive to mustard seed. Oral Allergy Syndrome typically results in short-lived itching, tingling, or burning in the mouth and is unlikely to result in a dangerous reaction. 

Spices can also cause reactions similar to allergic symptoms. For example, inhaling a puff of mustard powder can irritate the nasal passageways and trigger sneezing and coughing, but this response may not necessarily be an allergic reaction.

Food that contains mustard may cause a harmless rash around the mouth while baby eats or may cause or worsen diaper rash. Applying a thin layer of barrier ointment (such as pure petroleum jelly or a plant-based oil/wax balm) to baby’s face and bottom before mealtime can help prevent contact rashes.

Yes. Mustard seed is generally recognized as safe in amounts typically used in cooking. Mustard seed essential oil should be avoided for babies, as limited research is available on its safety for infants and young children. 

Yes. Mustard seed offers small amounts of various vitamins, minerals, and fiber. It also contains plant compounds like glucosinolates, which may have anti-inflammatory, antimicrobial, antioxidant, and anticancer properties.

While a high chair can help create a safe eating environment, there are alternative ways for baby to eat safely, such as holding the child on your lap or sitting together on the floor. For more information, see our article on high chairs.

None! Put solid food directly on baby’s tray, plate, or bowl, then let baby explore with their hands. If you like, keep a baby spoon or fork nearby to help familiarize the child with utensils, but the skills to use them are not expected until early toddlerhood.
