History

History of mushroom ingestion is helpful. Raw and cooked mushrooms as well as the cooking water are capable of producing toxicity through ALDH inhibition. Symptoms begin within minutes of ethanol ingestion. Patients may relate symptoms to ethanol, not mushrooms. Ascertaining if other species of wild mushrooms were ingested concomitantly and the approximate elapsed time since ingestion is important.

  • Sense of face and hand swelling

  • Nausea/vomiting
  • Metallic taste
  • Headache
