Is abalone high in histamine liberators?

Watch for

A mollusc, not a crustacean. Someone who reacts badly to prawns has no reliable information about abalone from that fact, and someone who reacts to abalone cannot assume prawns are the same problem. Research on mollusc allergy has shown mollusc tropomyosin driving a primary IgE response with no prior crustacean sensitisation, so the two are separate questions for an allergist rather than one / The green digestive gland, sold as abalone liver, accumulates pyropheophorbide a from the seaweed the animal grazes, and it does so seasonally. Feeding studies found the liver becomes toxic only in spring, and the resulting illness is a photosensitivity dermatitis: a light-triggered rash and swelling on sun-exposed skin, documented in cats and in people in Japan. The muscular foot, which is the part almost everyone eats, is not the problem / Histamine grades moderate (C) and tyramine moderate (C), both stacked in the same direction. Neither is a property of the species so much as of the supply chain, and most abalone reaches a kitchen frozen, canned or dried rather than live, which are three very different amine stories / Histamine liberation is unrated for abalone in this data, so treat it as unknown rather than clear if you are working a strict low-histamine protocol / Excluded on an eosinophilic esophagitis elimination diet as shellfish, and not vegan or vegetarian
