Here is what we recommend. Do the blood test for allergies. PHADIATOP/ ALATOP are the most renowned at the present point of time and easily available in big labs like Ranbaxy (SRL) and Lals Lab across India.
Then food avoidance is done as per tests is indicated. If tests are not possible or not helpful, the list of common foods to avoid include Milk, Egg, Peanut, Wheat, Soya, Shrimp and fish.
In India it is estimated that shrimp & fish allergy is likely less common.
