[31] As of 2018 six allergens have been identified to prawn alone; along with crab, it is the major culprit of seafood anaphylaxis. [13]

An allergen is an otherwise harmless substance that triggers an allergic reaction in sensitive individuals by stimulating an immune response.. In technical terms, an allergen is an antigen that is capable of stimulating a type-I hypersensitivity reaction in atopic individuals through immunoglobulin E (IgE) responses. [1]

[1] Type I is distinct from type II, type III and type IV hypersensitivities. The relevance of the Gell and Coombs ...
