A Case of Anaphylaxis Caused by Ingestion of Food Containing Cricket (Gryllus bimaculatus) Powder

A man aged in his 30s consulted our emergency room complaining of abdominal pain, nausea, diarrhea, pruritus, and erythema multiforme after ingestion of cricket (Gryllus bimaculatus) powder. An anaphylaxis diagnosis was made based on his clinical course and symptoms. Adrenalin was not administered, as his condition was stable, but antihistaminic agents were administered intravenously. His general condition over the following hours was uneventful, and he was discharged from our hospital the next day. Recently, entomophagy (eating insects, including crickets) has become a popular way to be compatible with sustainable development goals. However, as crickets have the same allergen as house dust mites and crustaceans, caution is required when people with this allergy consume foods that contain crickets.
