Same thing: Fish and shellfish have a tendency to concentrate iodine in their flesh. If you are allergic to iodine, often you will have a cross reactivity when you consume fish or shellfish. My wife, in fact, has this problem, and while she can eat fish from southern waters, she reacts poorly when she eats halibut caught in alaska. Particularly from the largest/oldest fish.

This is myth.: Shellfish allergy is one of the more common food allergies, mainly in adults, but the idea that iodine should also be avoided is a myth. Iodine does not cause allergy. Although shellfish does contain iodine, a teaspoon of iodized table salt contains over 10x as much iodine as 3 oz of shrimp. Fish and shellfish allergy is the result of allergy to proteins in the meat.
