What to know about prawn
Prawn is the British and Commonwealth name for what Americans call shrimp, and the trigger story is the same crustacean tale. Prawns are one of the major shellfish allergens, and they are routinely dipped in sulfites such as sodium metabisulfite at sea or in processing to stop the harmless black spotting called melanosis. That sulfite residue is a genuine trigger for sulfite-sensitive and asthmatic people. On top of that, prawn flesh accumulates moderate histamine as it sits, so how fresh and how cold it was kept matters as much as the packet label.
Watch for
- A top crustacean shellfish allergen, capable of a true IgE-mediated allergy that is separate from any sulfite or histamine reaction
- Frequently preserved with sulfites to prevent black spot, and that residue can set off wheezing, hives or flushing in sulfite-sensitive and asthmatic people
- Moderate histamine that climbs as prawns age, so older or poorly chilled prawns are riskier for anyone with histamine intolerance
- Moderate nickel, a minor consideration for people with systemic nickel allergy
