Seafood seems a rather easy allergy to manage, but as always when dealing with food allergies, it’s always more complicated. When it comes to Seafood, Shellfish gets the most publicity, yet Seafood Allergy can be caused by just about any fish. Seafood Allergy can affect more adults than children, and can be a lifelong allergy. That’s why it’s important to learn what types of Seafood can trigger a reaction. Now, according to ASCIA, it’s not just Shellfish that causes reactions. Scaly fish can be added to the list of Seafood that’s a no-go for allergy sufferers. Some people can be allergic to scaly fish, while being able to eat Prawns, or vise-versa.
