That's interesting. I don't understand all I know about the fractional
crystallization processes in our local salt ponds (where Artemia are
collected), but the refined salt product normally is way too *low* in
iodides, so potassium or sodium iodide has to be added to the final product
for safe human consumption (i.e., normal thyroid function). The Artemia may
sequester or concentrate iodides, but I'm not aware of that from talking to
local biologists. Certainly from my own experience, the local BS do not seem
to provide enough iodine to prevent fish thyroid.
Is the allergic reaction to elemental iodine used as a dye, or to the
iodides? The difference is as huge as chlorine vs chlorides. [The former
kills my Nothos and the latter keeps them from getting "velvet." ;-)]

Harry, all my evidence is purely anecdotal, so is worth every penny, but the
incidence of allergic reactions appears to be much higher to bloodworms (in
any form) than to brine shrimp among the Betta breeders. They tend to use
live, frozen and freeze-dried versions of both, as available, hence
