2. Find out the content of food ingredients

To prevent seafood allergies, there's nothing wrong with asking for ingredients from the menu that will be ordered when eating at a restaurant. Also make sure whether the cooking utensils used to cook seafood are different from other dishes.

3. Avoid places where seafood is sold or processed
