I'm not really pro-bureaucrat, but perhaps the standard for food should be slightly different. Just maybe, (novel) food (additives/preservatives/ingredients) should first be proven safe, rather than waiting until they're proven unsafe to prohibit them. It's not as if this was a substance humans regularly ingested for centuries and people are only now wigging out... look at the wikipedia entry for this. The only halogen that's not part of this thing is apparently bromine, the IUPAC name for the chemical's about as long as my comment here.
