Shellfish allergies are highly cross reactive, but its prevalence is much higher than that of fish allergy. Shellfish allergy is the leading cause of food allergy in U.S adults. [31] As of 2018 six allergens have been identified to prawn alone; along with crab, it is the major culprit of seafood anaphylaxis. [13]
Allergic reactions to latex range from Type I hypersensitivity, the most serious form of reaction, to Type IV hypersensitivity. [4] Rate of onset is directly proportional to the degree of allergy: Type I responses will begin showing symptoms within minutes of exposure to latex, while Type IV responses may take hours or days to appear.

Food allergy is principally diagnosed by careful history and examination. When reactions occur immediately after certain food ingestion then diagnosis is straight forward and can be documented by using carefully performed tests such as the skin prick test and the radioallergosorbent test RAST to detect specific IgE antibodies to specific food proteins and aero-allergens.
Hevein is the main IgE-binding epitope of the major latex allergen prohevein [4] as are hevein-like protein domains in fruit class I chitinases. [5] Therefore it is a possible cause for allergen cross-reactivity between latex and banana or other fruits like chestnuts or avocadoes. [6]
