Mustard allergy. Two anaphylactic reactions to ingestion of mustard sauce
1Allergy and Clinical Immunology Department, Valle de Hebron Children's Hospital, Universidad Autónoma, Barcelona, Spain.
Abstract:
Two cases of anaphylactic reactions set off by the ingestion of a small amount of mustard sauce are described. Mediation by specific IgE to mustard was determined by skin prick tests and radioimmunoassay, which suggested a type I hypersensitivity mechanism. Despite the antigenic potency of mustard, a spice that is consumed frequently, very few cases of hypersensitivity from ingestion have been described.
