Anecdotal evidence. Totally meaningless.
"It may be as this marine toxicologist (Dr. Susan Shaw) has testified: “This stuff is so toxic — combined, it’s not the oil alone, it’s not the dispersant — the dispersed oil that still contains this stuff, it’s very, very toxic and it goes right through skin.
Sorry, but at these low levels, the stuff would have to be more potent than botulinium toxin to have any effect at all. There is simply not enough dose available to have an effect.
It doesn't matter whether it "goes through the skin" or gets breathed in, or eaten. At these low concentrations, it's harmless to humans, and even adult fish. It "might" kill some marine larvae, but that is all. And half of it disappears every 10-20 days.

WKRG News in Mobile, Ala. recently ran an investigative report to see just how much oil and petroleum is in the water and sand. The lowest quantity of oil and petroleum found was 16 parts per million in water from Katrina Key, the highest being 221 parts per million in a sample taken from a pool of water in Orange Beach where a child was playing.
And something is seriously wrong when a water sample from Dauphin Island Marina exploded within seconds, breaking its glass container, probably the result of the presence of methane gas or a chemical oil dispersant in the water.
