![]() ![]() ![]() Sesame and mustard are both priority food allergens on Health Canada's list they must be identified on product labels. Seeds are now recognized as a significant food allergen with potential for anaphylaxis. Of atopic dermatitis in infancy are risk factors for development of peanut allergy in children. * Correspondence: of Pediatrics, Pediatric Allergy Clinic, Humber River Regional Hospital, c / o 404-586 Eglinton Avenue East, Toronto, ON Canada M4P 1P2 Fulllist of author information is available at the end of the article Both household presence of peanut and development While early ingestion of allergenic foods may promote the development of tolerance, one prominent hypothesis suggests that household exposure to allergenic proteins via an impaired skin barrier may contribute to the development of IgE sensitization to those food proteins. However, the factors involved have not yet been established. Given that studies report relatively rapid increase in worldwide prevalence of food allergy in the last decade, research has aimed to identify modifiable environmental factors that might contribute to this increase. Keywords: Sunflower seed, Allergy, Risk factors We suggest that homes which are intentionally peanut-safe may provide an environment whereby infants with impaired skin barrier are at increased risk of allergy to alternative "butter" products being used, via cutaneous exposure to these products preceding oral introduction to the child. Conclusions: A case of sunflower allergy in the context of household consumption of sunflower butter has not yet been reported. Epicutaneous skin testing elicited a >10 mm wheal size within 3-4 minutes in response to a slurry of whole poppy seeds and 8 mm to fresh pumpkin seed, which had never been consumed. Subsequent to the episodes above, the child ate a bread roll with visible poppy seeds and developed itchy throat, dyspnea, and urticaria. In lieu of peanut butter, sunflower butter was purchased and eaten frequently by family members, but not by the child reported herein. After the PNA diagnosis was made, the family home became peanut-free. This child has an older sibling with confirmed peanut allergy (PNA). Skin prick testing demonstrated a large positive (10 mm wheal) wheal-and-flare response to a slurry of fresh sunflower seed within 3-4 minutes associated with severe pruritus. A similar episode occurred to a commercial snack made with sunflower seed butter. Subsequently he vomited, and his symptoms gradually resolved. Sunflower seed butter is a peanut-free alternative to peanut butter, and sunflower seed allergy is an uncommon but reported entity.Ĭase presentation: A 3 year old boy presented with oral discomfort that developed almost immediately after he ate sunflower seeds for the first time. Household presence of peanut is a risk factor for the development of peanut allergy in children.
