An edible decapod (5 pairs of legs). Shrimp can be canned, breaded, frozen, sold in the shell or dried.
It is found in shallow and deep waters everywhere. The larger of the species, mostly in the Pacific, are called prawns. See also Crustaceans / Shellfish.
Shrimp is traditionally considered to be a highly allergenic food.
Pen a 1, the major allergen, a tropomyosin. (Reese 1999 ref.4259 0)
At least 80% of shrimp-allergic subjects react to tropomyosin. (Ayuso 2002 ref.5338 0)
Two main allergens have been isolated: Allergen I in raw shrimp and Allergen II, which is heat-stable, found in both raw and cooked shrimp. (Hoffman 1981 ref.808 43) (Yunginger 1990 ref.34 629) The heat-stable protein is a 34-kDa protein containing 300 amino acid residues. Allergen II (Antigen II or Sa II) is now referred to as Pen i 1.
18 antigens were found in extracts of shrimp, 5 cross react with crayfish, 3 with lobster and 1 with crab extract. Precipitin 3 may be a specific allergen, since it is present only in shrimp. (Lehrer 1985 ref.1199 3)
Shrimp of the Parapenaeus fissurus genus contain a 30 kd allergen. (Lin 1993 ref.1573 8)
A 38 kDa heat-stable protein has been isolated, and is a potent inhibitor of RAST to both cooked and raw shrimp. A second, weaker allergen of 21 kDa has been isolated from raw shrimp. (Hoffman 1981 ref.6194 5)
IGE AND IMMUNE:
Allergic reactions, including urticaria after contact with shrimp, respiratory symptoms, angioedema, nausea, vomiting, diarrhoea, and local anaphylaxis. Anaphylaxis. (Hoffman 1981 ref.6194 5) (Kemp 1995 ref.2958 5) (Yunginger 1990 ref.34 242).
In 48 patients, the most frequent causes of symptoms were shrimp (33 cases) and squid (24 cases); the most frequently found symptoms were Urticaria/angioedema (39 patients), asthma (18 patients) and rhinitis (14 patients). (Castillo 1994 ref.1572 3)
Food-dependent exercise-induced anaphylaxis. (Tokunaga 1995 ref.713 89) (Maulitz 1979 ref.496 32) A study reports on 7 cases of food-dependant exercise induced-anaphylaxis. The responsible foods were wheat (2 cases), corn, barley, shrimp, apple, paprika and mustard. (Mathelier-Fusade 2002 ref. 7125 2)
Interstitial cystitis. (Yamada 1984 ref.2620 0)
Allergy to airborne, heat-labile shrimp allergens. (Asero 2002 ref.5089 0)
Gamma radiation reduces the allergenicity of the heat-stable major allergen in brown shrimp. (Byun 2000 ref.5400 2)
Administration of aspirin before ingestion of food allergens (wheat or shrimp) induced urticaria in one patient and urticaria and hypotension in another, while aspirin alone or food alone elicited no response. The third patient developed urticaria only when he took all three items, i.e. aspirin, food and additional exercise, whereas provocation with any one or two of these did not induce any symptoms. These findings suggest that aspirin upregulates type I allergic responses to food in patients with food-dependent exercise-induced anaphylaxis (FDEIA), and further shows that aspirin synergizes with exercise to provoke symptoms of FDEIA. (Harada 2001 ref.5639 0)
In 148 Malaysian adults with symptoms of nasal congestion and rhinorrhea and 113 control subjects without rhinitis symptoms, skin prick test evaluation of 11 foods common to the Malaysian diet. 48% of the patients with rhinitis had positive SPT results to foods, compared with 4.4% of control subjects. The most commonly implicated foods were shrimp (48%) and rice (30%), which are common in the Malaysian diet. (Gendeh 2000 ref.7561 1)
In evaluating 163 asthmatic children with food allergy for food-induced asthma, using DBPCFC the most frequent offending foods were, sometimes in association, peanut (30.6%), egg (23.1%), cow's milk (9.3%), mustard (6.9%), codfish (6%), shrimp (4.5%), kiwi fruit (3.6%), hazelnut (2.7%), cashew nut (2.1%), almond (1.5%), garlic (1.2%). (Rance 2002 ref.7671 1)
Occupational asthma. (Lemiere 1996 ref.828 9)
Shrimp-allergic patients often have respiratory allergy; also an occupational allergen for seafood processors. (Daul 1990 ref.585 20)
Occupational protein contact dermatitis. (Scharer 2002 ref.5820 4)
Asthma and rhinoconjunctivitis due to occupational allergy. (Desjardins 1995 ref.721 32)
