Is Gulf Seafood Safe to Eat?
The FDA and NOAA say that Gulf seafood is fine. President Obama ate a fish taco yesterday made with Gulf fish.
So does that mean Gulf seafood is safe to eat?
I had hoped
- for the sake of the Gulf fishermen and the entire Gulf economy - that
the answer was yes. But after digging a bit, I'm not so sure.
For example, Local fishermen don't trust the safety of the fish:
"Fishermen "We do not think it is safe but the
here are calling it 'Voodoo seafood' because we are all cursed," said
Bill Thompson of Long Beach, Mississippi. Fishermen from Texas,
Louisiana, Alabama, Mississippi and Florida gathered in Biloxi last
week to discuss their fears.
state officials say it is. Who do you trust? The people that know these
waters or the government?" Thompson added.
"We do not think it is safe but the
Food and Drug Administration (FDA) reports that of all the samples of
seafood that have been tested since the oil spill, none have shown
evidence of contamination.
While some in the coastal seafood industry agree with these assessments, a majority seem to view the news with a sense of betrayal.
cleanup isn't even close to being done," said Karen Hopkins of Dean
Blanchard Seafood, which accounts for about 11 percent of the U.S.
shrimp supply, on the barrier island of Grand Isle.
thing I want to do is scare anyone away from the seafood down here,"
said Dawn Nunez, standing at the counter of the shrimp wholesale
business and deli she owns in the tiny fishing town of Hopedale. "But if I’m not eating it or feeding it to my children, I can’t advise anyone else to eat it either."
As AOL news notes:
contamination is known to cause cancer and brain damage. But how much
oil and gas does it take to make seafood dangerous?
low doses of even the strongest poison won't cause health problems, so
it is all a question of how much oil - if any - is making it into Gulf
seafood. But as the AOL News article notes, BP might be lobbying to
raise the amount of oil in seafood which is considered safe.
And its not just oil.
As Fox 8 in New Orleans reports:
at Tulane say it appears they've detected a Corexit sort of fingerprint
in the orange blobs found lodged in the bodies of tiny blue crab larvae
collected from marshes that stretch from Texas to Florida.
of New Orleans’ Martin O’Connell, Ph.D] said O'Connell said most
components of oil won't bio-accumulate, meaning oil likely won't reach
the food chain. As for Corexit, he said, "no one really knows." "If
you're a small fish and you eat 1,000 of these small crab larvae and
all of them have oil or Corexit droplets in them they could get into
the fish.. that little fish could be eaten and so on and so on," said
Sky News notes:
George Crozier] director of the Dauphin Island Sea Lab is worried about
the potential build up of some chemical compounds in the food chain.
is particularly concerned about polycyclic aromatic hydrocarbons… “If
we do see over the years fish accumulating PAH, it will almost
certainly be attributable to Deepwater Horizon… I can imagine 10 or 20
years from now there will be the same kind of health warnings about
say, grouper or snapper from the centre of the Gulf, that apply to tuna
from all over the world, for mercury.”
NOAA admitted in a Congressional hearing that seafood isn't being tested for dispersants, even though they may bioaccumulate.
It is well-known that the EPA buried the concerns of its own toxicologists about the application of Corexit. As the Guardian points out:
Obama administration is facing internal dissent from its scientists for
approving the use of huge quantities of chemical dispersants to tackle
the oil spill in the Gulf of Mexico, the Guardian has learned.
Ruch, the executive director of the whistleblower support group Public
Employees for Environmental Responsibility, said he had heard from five
[EPA] scientists and two other officials who had expressed concerns to
their superiors about the use of dispersants.
"There was one
toxicologist who was very concerned about the underwater application
particularly," he said. "The concern was the agency appeared to be
flying blind and not consulting its own specialists and even the
literature that was available."
Veterans of the Exxon Valdez
spill questioned the wisdom of trying to break up the oil in the deep
water at the same time as trying to skim it on the surface. Other EPA
experts raised alarm about the effect of dispersants on seafood.
said EPA experts were being excluded from decision-making on the spill.
"Other than a few people in the united command, there is no involvement
from the rest of the agency," he said. EPA scientists would not go
public for fear of retaliation, he added.
scientists also criticised the EPA for claiming that the combination of
oil and dispersants posed no greater danger to marine life on its own.
Wednesday, a toxicologist from Texas Tech University is scheduled to
tell a Senate hearing that the unprecedented use of dispersants
"created an eco-toxicological experiment".
"The bottom line is
that a lot of oil is still at sea dispersed in the water column," said
Ron Kendall. "It's a big ecological question as to how this will
ultimately unfold." Previous studies, including a 400-page study by the
National Academy of Sciences, have warned that the combination of oil
and dispersants is more toxic than oil on its own, because the
chemicals break down cell walls, making organisms more susceptible to
The EPA issued a report on Monday, based on a study of
how much of the mixture was needed to kill a species of shrimp and
small fish, just two of the 15,000 types of marine life in the Gulf.
The EPA test did not address medium- or long-term effects, or reports
last week that dispersants were discovered in the larvae of blue crab,
entering the food chain.
Hugh Kaufman, a senior EPA policy analyst, dismissed the tests as little more than a PR stunt.
But isn't this all old news, because the Corexit has already broken down in the environment? Maybe. But as the Press-Register noted on August 6th:
The stained, brown water seen washing up in pockets along Alabama beaches for the last two weeks appears to contain the dispersant widely used on oil from the Deepwater Horizon spill, according to a preliminary analysis.
Overton, a Louisiana State University chemist… [who] is analyzing oil
samples for the federal government… said… “indications [are] that there
was a dispersant signal in the sample.” … [T]he signal was similar to a Corexit sample.
Perry, a scientist at the Gulf Coast Research Lab in Ocean Springs
[said]… “It looks like they found [COrexit],” Perry said of work by
research colleagues at Tulane University [researching crab larvae]…
“For a droplet to be that small, it has to be dispersed oil… It’s
supposed to biodegrade rapidly. It’s supposed to disappear in days, not
weeks, but that may not be happening.”
addition, some claim that even the chemicals left behind when Corexit
breaks down are toxic, although I have seen no scientific evidence one
way or the other.
The bottom line is that some Gulf seafood is probably safe and other
Gulf seafood is probably not very safe, depending on where it swam in
relation to the oil plumes and a host of other factors. But since the
government is being close-lipped about the details of its test results
- and isn't even testing for dispersants - it is hard to know whether a
particular piece of seafood is safe or not.
