How Mercury-Tainted Tuna Damages Fetal Brains

By Sandra Steingraber

Last spring, I received a tantalizing invitation from the editor of Childbirth Forum: write a story on mercury in fish and the resulting risks to pregnant women. This was a topic dear to my heart. During the four years I researched fetal toxicology at Cornell [RETURN TO ARTICLE]

    Suggestion: Switch your Diet according to the findings of Natural Hygiene.
    Processed foods are sickening, in many cases
    you see the consequences before death.

    Mary Beth Doyle was my sister—I miss her dearly, but am warmed to see her influence here.  I hope to carry on her work now. 

      Mary Beth loved the world as much as anyone I have known, and she was all too aware of the damage we have done to ourselves and our children.

      Mary Beth was passionate, but never strident.  It’s a world worth fighting for—

    As stated by the author, coal-burning power plants dump 50 tons of mercury into the atmosphere every year.  There is some good news on this front, though.  See http://www.solucorpltd.com/ for a description of existing technology that can remove up to 95% of the mercury during coal combustion.  Coal usage will no doubt increase as the availability of oil declines.  Therefore, we must do all we can to encourage cleaner coal technologies in parallel with the development of renewable energy technologies.

    I can’t believe more people aren’t outraged about this issue.  So many people eat Tuna, Salmon, and other mercury-laden fish with some regularity.  And then we have Bush loosening the New Source Review regulations so that coal power plants don’t have to update their equipment with cleaner technology.  Don’t Republicans eat fish too?

    United States Posted by Phil on Dec 29, 2004 at 4:03 AM

    By not regulating the business is serves the purposes of Corporatism and laissez fare “free market” economics.  It also serves the goal of dumbing down the populace, first by destroying education, then turning the media into a corporate circus serving nothing but distraction, now brain damage and retardation.  All these make it easier to control the sheeple. 

    People should be outraged, but you really do not see much made of this in the mainstream media.  Also, remember, Republicans in control could care less about anyone, sociopaths.  Those in power will take care of themselves.  Screw the rest.  That’s the message I see with the current political leaderships actions.

    I read about a study done in the Saychelles Islands that came up with results contradicting all the rest—-the women ate lots of mercury-tainted fish, and their babies were fine. Turns out the study was funded by an electric lobby group and tuna canning group. In other words, like Proctor & Gamble’s people here, certain people made a conscious decision that protecting their company’s profits was worth an unknown number of brain-damaged babies. I expect these people go to church every Sunday and voted for Bush because of their strict and firm Moral Values.

    I work for P&G in Europe, but I am writing you as a reader. I do no think there is any link between the making of soap and your publication issue. The chlor-alkali process is a foundation of the plastic industry. Caustic soda is just a byproduct, that is usefully employed in the making of detergents.

    More simply what may have happened is that P&G External relations is very careful in getting the company involved in sensitive debates, especially when no company official position is required (and probably we do not have internal experts).

    I wish an HAPPY 2005 and I hope you will be able to publish your paper somehow.

    Great story - maybe the reason for not publishing lies with the fact that many people reading it may “connect the dots” - if the amount of mercury ingested in tuna sandwiches can result in potential damage to the fetal brain - as brain cell migration begins in the 4th month of pregnancy, continuing after birth until at lest age 2, what about the damage that can be caused by all the mercury in the infancy/childhood vaccinations - injected into a tiny bloodstream and capable of crossing the blood-brain barrier? (which is not fully developed in an infant or a two-year old!)

    I agree with J. Taylor. YOur next in-depth article should be on mercury in vaccinations (in the form of thimerosol). Our poor children are made toxic if we choose the typical vaccination schedule.

    After reading the previous emails about P&G evidently pulling the plug on the wonderful mercury story and that allegedly P&G does not use mercury, it fails to explain why P&G officials would lobby the Governor of Maine against that state’s mercury regulations. P&G must use mercury in some product or they would not have any concerns about Maine’s mercury regs, if it had no impact on their corporate bottom line. It sounds like the P&G link is the CAUSTIC SODA used to make soap and that the P&G person either does not know what they are talking about or is misleading the forum on P&G.

    United States Posted by Neil Carman on Jan 11, 2005 at 5:15 PM

    Just to clarify for Neil Carman:

    The old technology for the chlor-alkali process did indeed use Mercury based electrodes. Today all modern processes have converted to the much cleaner Membrane technology, so hopefully there is no risk of mercury contamination coming from this new processes. Also note that heavy metals, not only can have adverse biological effect, but also create all kind of issues in detergents making and quality…nobody wants them around really…:-)

    My two youngest children were born in 1996/98.  At that time I was receiving WIC (Women, Infant, Children)coupons.  Our family, therefore, ate a great deal of tuna while I was pregnant and breastfeeding.  My youngest child is autistic.  I don’t receive WIC anymore so I do not know if they are still giving these coupons for tuna to pregnant and breastfeeding women.

    United States Posted by Sue Phipps on Jan 13, 2005 at 6:52 AM

    As the mother of an autistic son, I never ate tuna or any other fish during pregnancy.  However, I want to reiterate that there are other dangerous sources of mercury and other toxins out there worth mentioning.  Fillings and Vaccines.  When we used a chelator to test my son’s levels, metals came poring out and later tests showed he had low levels of glutathione, the protein that binds with mercury to remove it.  Please don’t leave those important pieces of the puzzle out.

    United States Posted by Marcy Kelly on Jan 13, 2005 at 12:08 PM

    My second daughter was born in 1994.  When I was pregnant with her I craved tuna sandwiches.  I must have ate them at least twice a week or more.  I wish I knew then what I know now.
    She is moderately to severely autistic as well as
    other problems.  I had no idea there was any risk or danger from mercury at the time.  If I had known I think there is a chance she may not be autistic.  I am wondering how much mercury was in my body at the time?

    United States Posted by Kathryn Hudson on Jan 13, 2005 at 3:18 PM

    As a therapist for families and children with autism and related disorders, I have seen the result of the mercury debacle.  Please, continue to go above and beyond to teach potential parents about the risks of mercury and other environmental toxins that are all around us.  The EPIDEMIC will not slow unless our society becomes more informed.  And if your child is already affected, please use a strategy that helps rebuild your child’s missing pieces in a respectful and loving way; Floortime (www.floortime.org)  Thank you.

    A report published by the organization Safeminds in 2004 illuminates why P&G would not want to support publication of this article.  It includes data provided by the EPA on mercury in household cleaners:
    http://www.safeminds.org/pressroom/press_releases/08Sep2004_A_Brief_Analysis.html

    Laboratory analyses were conducted on several common cleaners and show that mercury exposure can also occur through unsuspecting sources.[69]

    These findings, which have not been widely acknowledged within this discussion, need to be further evaluated. 


    The take away message for hospital personnel from the EPA:  For most mercury containing products in the hospital, the preferred best management practice is to replace the item with a mercury-free product.

    [69] The laboratory analyses were conducted by the Massachusetts Water Resources Authority (MWRA) and Medical, Academic and Scientific Organizations,Inc. (MASCO) thorug a public-private partnership called the MWRA/MASCO Mercury Work Group.  These tests were on limited, many common cleaning products have not been tested.  Reducing Mercury Use in Health Care Page 10, http://www.epa.gov/glnpo/bnsdocs/merchealth/mercury.pdf

    Mothers were “injected” with mercury via RhoGam or the Flu Vaccine while they were pregnant. These injections conatined 25-35 mcg of mercury.

    For a 132 lb woman the EPA limit for “ingesting” mercury would be 6 mcg, These women were injected with 35 mcg!! And there is a HUGE diffrence between Ingesting mercury and Injecting it!

    United States Posted by DA on Jan 14, 2005 at 10:31 AM

    Myth:The mercury received in a vaccine is no greater than in a can of
    tuna. Eating a can of tuna has certainly never caused autism.

    This myth has received a lot of publicity because it offers an analogy
    anyone can understand and makes the mercury-autism
    connection appear trivial.

    The analogy can be improved by comparing a 200-pound male adult consuming
    tuna with the infant who receives a single
    vaccine on their first day of birth (since day-old infants don’t eat tuna). 

    On the first day of birth an infant receives the Hep B vaccine with about
    25 micrograms of ethlymercury - this does approximate the 30 micrograms of
    methlymercury in an average can of tuna. Since the average infant weighs
    about 7 pounds, the weight equivalent
    number of cans of tuna for an adult would be 28 cans.

    If you take those 28 cans of tuna and distill it down to mercury content,
    you would have 840 micrograms of mercury. Keep in
    mind that the stomach successfully absorbs and excretes about 90%  of any
    mercury ingested through food, leaving only about 10% of the mercury for
    the bloodstream. Since the mercury in vaccines is injected directly into
    the bloodstream where 100% of it can be absorbed by the organs, you’d need
    an additional 252 cans of tuna to get the equivalent amount of mercury
    into the bloodstream for a
    total of 280 cans of tuna and 8,400 micrograms of methlymercury.

    So, receiving the Hep B vaccine on the first day of birth is the
    equivalent of a 200-pound adult male consuming 280 cans of
    tuna in a single day. One final adjustment: the adult male in the analogy
    needs to have no capacity to excrete mercury. As Boyd Haley, Ph.D.  notes,
    “it is very well known that infants do not produce significant levels of
    bile or have adult renal capacity for several months after birth. Bilary
    transport is the major biochemical route by which mercury is removed from
    the body, and infants cannot do this very well.”

    So, a 200-pound male who consumes 280 cans of tuna in a single day and has
    their ability to excrete mercury severely diminished is the same as a
    day-old infant receiving the Hep B vaccine. That’s a fair analogy.

    Did you notice that P&G Products (Joy, Ivory) appear at the very bottom of the above list list with measured Mercury levels of about 1/100 of a billionth? Let me also point out that the way of reporting the levels for some of the values (<...) it typical of a measurement that is below detection limit…

    For sure P&G is such a large corporation that one can always point a finger to this or that mistake, but really this does not seem to be a very good case.

    United States Posted by Sergio Barbarino on Jan 15, 2005 at 6:39 AM

    To correct Sergio correcting Neil:  Most US chlorine is made with mercury-free processes, however, there are still 9 chlor-alkali plants in the US that use mercury-cell technology.  In addition, there are 53 plants with mercury-cell technology in Europe, about 13 in South America and many in Asia. 

    The products co-produced are chlorine and caustic soda which are used in a wide variety of products including bleach, paper, plastics, and detergents.

    United States Posted by Dawn on Jan 20, 2005 at 8:25 AM

    In response to Rhonda:  Do you have any sources for for the 25 micrograms of ethylmercury in Hep B vaccines?  I was under the impression that thimerosal, the mercury containing compound had been significantly reduced in vaccines given to children over the past few years. http://answers.google.com/answers/threadview?id=113001

    Though I suppose according the nvic (and ‘DA’ above) we should all still rightly be on the lookout just in case. http://www.nvic.org/Issues/mercury.htm

    Dave, congrats on the first joke on this comment board.  There is one method that I know of to rid the body of mercury, though usually not until a child is older because of the impact on the kidneys.  It is called chelation, and is part of the DAN protocol (Defeat Autism Now).  I have seen the treatment in various stages, and I think that it works to rid the body of mercury and other heavy metals.  Chelation is still not fully proven as effective because there is no solid research yet, so research it yourself if you are interested.

    what does anyone know or think about the use of chlorella for detoxing, especially for infants?

    United States Posted by Tanya on Mar 18, 2005 at 5:31 AM

    I have an autistic son who is 5. I believe that mercury poisoning is responsible. I am rh- and got a rhoGam shot at 28 weeks and another one immediatly after my son was born. I breastfed my son for 4 1/2 months-which means the shot of rhoGam I got after delivery was in my breastmilk. That along with all the vaccines I took my son to get (being a good mom) which I now regret more than anything…
    What now?
    Aside from the thousands of dollars a month in therapies-what can I do?
    Chelation?
    File suit for being injured by rhoGam?
    By Thimerosal?
    We are desperate for help for our son and for financial help to pay for his care.
    It is such a tragedy that so many children and families lives have been destroyed by mercury poisoning-the responsible agencies don’t care- we are just left to try to pick up all the pieces.

    Have you read Amy Lansky’s book on treating her autisitc son with homeopathy?  it is getting quite a display—at least in holisitc circles.
    The title is Impossible Cure:  The Promise of Homeopathy.  You can read comments on this book and purchase it at

    www.minimum.com/b.asp?a=impossible-cure-lansky - 13k - Apr 9, 2005

    In case you may not know, Homeopathy is a very potent source of healing which is non-invasive and quite cost efficient in the long run. It is holistic and has a distinct core philosophy and a set of protocols that are followed.  If you would like more information on using homeopathy you can write me at tamarque@earthlink.net and I would be happy to give you more information.

    My heart felt sorrow for your pain and frustration on this terrible situation.

    My son was poisoned by the vaccinations he received at 1 year.  He was diagnosed with autism when he was 2 years old.  My son has had ABA therapy since he was 2 1/2 and has been on the gf/cf diet since he was almost 3.(He is now 5)  These interventions have helped tremendously but he is still mostly non-verbal but he tries very hard.  We are getting ready to start chelation and are considering DMSA.  Anyone have any comments on this chelation method?

    Bayer made Rhogam that contained 35 mcg of mercury, Bayer in 2003

    Petitioned OEHHA to take thimerosal/mercury off the list of
    reproductive toxins,

    Here is OEHHA reply to Bayer.

    OEHHA (Office of Environmental Health Hazard Assesment) reports;

    “The scientific evidence that PMA and Thimerosal cause reproductive
    toxcitity is CLEAR and VOLUMINOUS.

    The evidence for its reproductive toxcitity includes severe mental
    retardation or malformations in human offspring who were poisoned
    when thier mothers were exposed to ethylmercury or thimerosal while
    pregnant.”

    Thimerosal causes DNA Methylation

    http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=14745455&dopt=Abstract

     


    NIH-funded study that was
    published

    online today in the journal of the National Institute of Environmental
    Health Sciences

    Burbacher
    and his colleagues

    show that more inorganic mercury accumulates in the brain after
    thimerosal exposure

    through injection than after exposure to methylmercury in food. The
    accumulation of

    mercury in the brain after injection with thimerosal occurred even
    though ethylmercury is

    cleared from the blood faster than methylmercury.

    Page 17:

    “There was a much HIGHER proportion of inorganic mercury in
    the brain of thimerosal than methylmercury infants (up to 71% vs
    10%)”

    Regarding Chelation - I have seen success with both modes of Chelation.  You might also want to consider trying Floortime therapy at this point since your child is trying so hard and is not yet verbal.  It addresses most of the primary symptoms of autism as it treats the sensory, emotional, and social areas of development that are the foundation for language.  Please learn more at www.floortime.org.

    People around here are catching on. I put them on to Bernies site. I had 9 mercury fillings in 1980. My blood sugar was very unstable, I was sick. I went to a dentist who was willing to remove them and had them all replaced with acrylic. My blood sugar started to level off. But my digestive tract is damaged a lot, such that after 20 years I still have GI problems.
      I lived 1/4 mile from a pond in Maine full with effluent from the paper mill. That’s where people at married student houseing got their water, It also had copper pipes,rust& algea and pulp in the drinking water.Ya never knew what you were going to get.  Ive had chronic colitis ever since then-20 years. I figure it’s taken 25 years to get the mercury out. I was given 12 vials of eye drops when I had eye surgery at El Dorado clinic back in 1982 . All of it loaded with thimerosal. I has eye spasms and so I stopped useing their kindly provided samples . My internist had a letter from the AMA posted on his board back in ‘93 that stated that it was ” medically irresposible” to recomment that mercury amalgam fillings be removed . Today there is informed consent legislation in 6 states -before they can load you up with mercury .
    One must ask why haven’t the writers of this article talked about mercury in your mouth? How much more direct can exposure be? Get ‘em out even if you have to sell your car to pay for it and do it when you aren’t going to be preganant for a few years . type > bernie + mercury into google.
    Fish? That’s the tip of the iceberg!
    Goal : evidence based medicine
    Task: reduce paper
    Task remove the fillings
    No vaccines for underweight babies till they add the weight
    military recruits get 15 shots!Travel shots same deal. Request them not to have thimerasol!
    Finally stop patronising republican owned businesses and dump your republican friends and your republican church and the idiots they have elected .They are friends to no humans .

    I was just reading the article “Deadly Immunity” published by Salon & Rolling Stone.  It is very informative and I hope it gets a lot of attention.
    My son, who is now 5 years old, was damaged by his 1 year vaccinations.  It gives me great pleasure to see articles that expose the truth!

    United States Posted by Brenda Price on Jun 17, 2005 at 6:07 AM

    thanks for the link to the Rolling Stones article.
    although the basic information on mercury toxicity is not new, the article is remarkable for the expose on the level of complicity and manipulation by the government and the pharma industry.  i also found the presentation by a lawyer to provide a level of credibility that is unusual. and third, i was impressed with the coherence of his presentation, especially linking the introduction and increasing rates of autism in other countries; ie, china and india.  i have been keeping an eye open for just this information.  i am confident that it is only a matter of time before we see thimerosol in vaccines banned completely.  after mercury, the next step will be to look at the impact of vaccines themselves and the bogus nature of the theory behind them. what a sinister country we live in!
