This is exactly why I don't eat gulf seafood any more. When I was in college, I scored a job working some oil rigs in the gulf for a summer. It paid really well, but most of the experienced rig workers told me blowouts and spills were common place and often covered up. In fact the only real difference with Deppwater Horizon was that the damn thing sunk and people died, so it got publicity. Basically they told me the gulf sea floor is likely a wasteland at this point.

And given how liberally the corexit was used in DH, I just don't eat gulf seafood, or seafood that may come from the gulf anymore, which sucks because I LOVE fish, and fishing. But now im mostly catch and release.
