I'm allergic shellfish fish and iodine 100% does that mean I can't have sea salt?

Everything has seasalt in it now and my food sources are getting scarce because I'm too afraid to try it. I carry an epipen because I'm severly allergic to all fish as it is and I haven't been to a resturaunt in over ten years! It's really hard to shop for groceries having to read all the labels as it is now. I know seasalt is better for you but I think people are forgetting about the allergic people out there.. Have any input?
