More than 9,000 square miles of U.S. federal Gulf waters are closed to commercial and recreational fishing today thanks to the BP oil spill. However, government offices today claimed that seafood from the Gulf is basically safe to consume, based on the results from their latest battery of tests.
You gonna eat that? Companies responsible for the environmental disaster spilled about 5 million gallons of oil, accidentally. They poured about 2 million gallons of oil dispersants into the Gulf waters on purpose, though. The dispersants were supposed to break up the wildlife-choking slicks into droplets that could be more easily digested by oil-eating bacteria. Or at least, they’d make the water look more like water and less like tar while the cameras were flying overhead.
At the time of the spill, the U.S. Geological Survey (USGS) sent scientists to the Gulf to help with the oil spill cleanup. Even that federal office knew nothing about the dispersants’ likely impact on sea life or humans. USGS director Maria McNutt admitted to her office’s ignorance at last week’s 2010 PopTech conference.
By May, the St. Petersburg Times reported, there were still no federal standards for how much dispersant could be present in seafood consumed by humans, a detail the paper confirmed with the National Oceanic and Atmospheric Administration (NOAA).
Here’s what the National Oceanic and Atmospheric Administration (NOAA) and U.S. Food and Drug Administration (FDA) claimed in their joint press statement today regarding the safety of seafood in the Gulf, though:
Building upon the extensive testing and protocols already in use by federal, state and local officials for the fishing waters of the Gulf, NOAA and FDA have developed and are using a chemical test to detect dispersants used in the Deepwater Horizon-BP oil spill in fish, oysters, crab and shrimp….
Experts trained in a rigorous sensory analysis process have been testing Gulf seafood for the presence of contaminants, and every seafood sample from reopened waters has passed sensory testing for contamination with oil and dispersant. Nonetheless, to ensure consumers have total confidence in the [emphasis added] safety of seafood being harvested from the Gulf, NOAA and FDA have added [a] second test for dispersant when considering reopening Gulf waters to fishing.
Using this new, second test, in the Gulf scientists have tested 1,735 tissue samples including more than half of those collected to reopen Gulf of Mexico federal waters. Only a few showed trace amounts of dispersants residue (13 of the 1,735) and they were well below the safety threshold of 100 parts per million for finfish and 500 parts per million for shrimp, crabs and oysters. As such, they do not pose a threat to human health.
The press statement follows an investigative report by English Al Jazeera about the dispersants’ impact on people and our environment that concluded:
The Gulf has suffered the largest accidental marine oil spill in history. Compounding the problem, BP has admitted to using at least 1.9 million gallons of widely banned toxic dispersants… Dispersed, weathered oil continues to flow ashore daily…
[Human] health impacts include headaches, vomiting, diarrhea, abdominal pains, chest pains, respiratory system damage, skin sensitization, hypertension, central nervous system depression, neurotoxic effects, genetic mutations, cardiac arrhythmia, and cardiovascular damage…
One researcher studying the impact of dispersants in the Gulf, told Al Jazeera about dolphins— and people— hemorrhaging from too much dispersant exposure. Gulf residents showed off pieces of their boats that had been eaten away by dispersant-contaminated waters over just a short time.
How could the new FDA-NOAA tests declare the seafood from the Gulf oil spill waters safe to eat in light of Al Jazeera’s (and so many others’) reports? According to the press statement, the labs tested for traces of dioctyl sodium sulfosuccinate, a.k.a. DOSS, a component of the dispersants used in the Gulf that’s approved by the FDA for use in various household products and over-the-counter medication at low levels.
It didn’t test for the other stuff that’s included in Corexit 9500, the primary dispersant used by BP, and still being sprayed over the Gulf these days, including 2-butoxyethanol, and a host of other things that for some reason, the company just won’t reveal to the public.

Is it possible that in the years since the Exxon Valdez, that Kevin Costner is the only one who has invested money into the technology of oil spill cleanup?”
