Recognition of anaphylaxis following ingestion of mixed flour contaminated by mites

Abstract

We recently encountered 3 cases in which systemic anaphylaxis developed after eating mixed flour contaminated by mites. Since 1993, systemic allergic reactions following ingestion of foods made using mite-contaminated wheat flour have been reported; therefore, we developed a questionnaire regarding mixed flour contaminated by mites. Responses were received from the caregivers of 54 children treated in the allergy division of our department. 38.9% of caregivers had knowledge about allergic reactions following ingestion of mixed flour contaminated by mites, and 64.9% of caregivers did not always store mixed flour in the refrigerator. At-risk populations of allergic patients should be informed about prophylactic measures.
