Summary
Two individuals experienced severe allergic reactions (anaphylaxis) after eating food contaminated with storage mites. This is the first report linking ingested storage mites, like Tyrophagus putrescentiae, to systemic anaphylaxis in sensitive people.
Area of Science:
- Allergy and Immunology
- Food Safety
- Entomology
Background:
- Systemic anaphylaxis is a severe, life-threatening allergic reaction.
- Food allergies are common, but reactions to contaminants are less understood.
- Storage mites are common household pests, often found in stored food products.
Observation:
- Two patients presented with anaphylaxis shortly after consuming food.
- Testing revealed sensitivity to storage mites (Tyrophagus putrescentiae) but not common food allergens.
- The implicated food was confirmed to be contaminated with storage mites.
Findings:
- Ingestion of storage mites (Tyrophagus putrescentiae) can trigger systemic anaphylaxis.
- This study provides the first documented evidence of anaphylaxis caused by consuming storage mites.
- Specific IgE antibodies to storage mites were confirmed in the affected individuals.
Implications:
- Highlights the potential for foodborne allergens beyond conventional food sources.
- Suggests the need for increased awareness of storage mite contamination in food safety protocols.
- Informs diagnostic approaches for unexplained anaphylaxis cases, considering environmental allergens in food.
