To the Editor:Food-induced anaphylaxis is occurring more frequently in response to composite foods where the culprit may be a contaminant.1 A few published case reports describe anaphylactic reactions in patients after consuming foods contaminated with mold. One patient died after consuming mold-contaminated pancake mix.2 Another experienced a non-life threatening anaphylactic reaction to mold-contaminated bee-pollen.3 A case of true anaphylaxis occurred after a patient consumed dry cured meat products that require mold in their preparation.4 Quorn, a meat substitute made with mycoprotein, caused a lethal anaphylactic reaction in a pediatric patient with a previously known mold allergy.5Multiple reports on the internet and news outlets have described parents finding mold in preservative-free juice drinks, but no reports have described allergic reactions.
