Pyriproxyfen Suspected of Causing Microcephaly in Brazil

“Malformations detected in thousands of children from pregnant women living in areas where the Brazilian state added pyriproxyfen to drinking water is not a coincidence…” — Médicos de Pueblos Fumigados

A report published by Médicos de Pueblos Fumigados (Physicians in the Crop-Sprayed Villages) of Argentina on February 3, 2016 discounts the theory that the growth in the number of cases of babies born with microcephaly in Brazil during the past year are due to the Zika virus transmitted by mosquitoes.1

The authors of the report, which include Medardo Avila Vazquez, MD (a pediatrician specializing in environmental health2) and a team of researchers, propose that a chemical known as pyriproxyfen may be at the root of the microcephaly. Pyriproxyfen (C20H19NO3), which is produced by Sumitomo Chemical Co., Ltd. of Tokyo, Japan and recommended by the World Health Organization (WHO), is a pyridine-based pesticide designed to eradicate mosquitoes that may carry diseases. It specifically inhibits the growth of mosquito larvae. Sumitomo Chemical is a strategic partner of Monsanto Company of St. Louis, MO.1

According to the report:

A dramatic increase of congenital malformations, especially microcephaly in newborns, was detected and quickly linked to the Zika virus by the Brazilian Ministry of Health. However, they fail to recognise that in the area where most sick persons live, a chemical larvicide producing malformations in mosquitoes has been applied for 18 months, and that this poison (pyriproxyfen) is applied by the State on drinking water used by the affected population.1

The authors emphasize that they do not believe it is mere coincidence that the areas (the northeastern region of Pernambuco state) where the Brazilian government added pyriproxyfen to the drinking water supply in 20143 are the same areas in which the vast number of microcephaly cases have been detected.

Malformations detected in thousands of children from pregnant women living in areas where the Brazilian state added pyriproxyfen to drinking water is not a coincidence, even though the Ministry of Health places a direct blame on Zika virus for this damage, while trying to ignore its responsibility and ruling out the hypothesis of direct and cumulative chemical damage caused by years of endocrine and immunological disruption of the affected population.1

The report cites a Brazilian association of doctors and health researchers called the Asociación Brasileña de Salud Colectiva (Brazilian Association for Collective Health), or ABRASCO,3 which believes that the widespread use of chemicals in Brazil is “contaminating the environment as well as people,” and that the fumigation strategy is a “commercial manoeuvre” by the international chemical industry “deeply integrated into Latin American ministries of health as well as WHO and [the Pan American Health Organization].”1

A recent report by ABRASCO confirms that in 2014 the Brazilian government did, in fact, introduce pyriproxyfen in the “drinking water of the population in households and public roads.”4 5

Pyriproxyfen was introduced as an insecticide in the United States in the mid-1990s to protect cotton crops against whiteflies. It was first registered in Arizona in 1996.6

  1. It figures, and lines right up with other existing theories that all uses of chemicals have unintended consequences. That’s why we use a Berkey water filter, because farm run off is a serious concern for many residents who’s municipalities serve up surface water, rather than well water, via municipal supply lines. Does your water come from well or surface in your county, to your home and/or work? You should know these things, and filter with gravity and ultra micro filters accordingly. Another story illustrating lack of clean drinking water is to blame. Sounds more realistic than blaming mosquitoes.

    1. The consequences are not ‘unintended’. “Mistakes” is the cover word constantly used to disarm the public.
      If these bureaucrats and ‘experts’ are such freaking experts, how can they make so many ‘mistakes’?

  2. Amazing what happens when someone does a little digging and ends up debunking a theory being manipulated into an world epidemic emergency demanding a vaccine for a little known viral infection that expresses itself as mostly mild flu-like symptoms and with no symptoms on over 80% infected. Big Pharma is readying an emergency vaccine in an effort to make another few $Billions from the resulting panic. Microcephaly is certainly a concern, but lets find the real cause for it and address it without endangering any others with an non-needed additional vaccine.

    1. Yep. I commented on that in the other weekly nvic article. With attention focused on Brazil for the Olympics, we’re learning how awfully polluted the land and living areas are. All anyone needs to do, to ‘discover’ problems there, is lift the blindfold, and actually look.

  3. Unfortunately (or maybe not so unfortunately at all) the most logical explanation will not be researched and followed-up on: This so-called “new epedemic” started in Brasil in May 2015. In October 2014 the Brasilian Health Department started vaccinating pregnant women with the Tdap vaccine Boostrix from GlaxoSmithKline (GSK), a British vaccine producer. Anybody who is not only sucking up the pro vaccine propaganda and just delves into the matter a little more thoroughly knows how dangerous vaccines really are especially to pregannt women and the fetus, but the money for industry, science, doctors and other interested parties is mindblowing and too tempting. Don’t expect anybody – especially not the WHO or Bill Gates Foundation – to follow up on this trail, it is so much more “enriching” to put the blame on a virus and develop a new vaccine.

  4. Questions: when pyriproxyfen was introduced to the US, was it added to the water supply? Was there an increase in birth defects in the US when it was introduced? And does anyone know if microcephaly or other unusual birth defects have been found in the young of other species in the affected region of Brazil?

      1. Fernando,

        unfortunately I do not speak Spanish. Do you know if this articale could be had in English or maybe you could just give me a short translation, the main points what it says. I know that studies are manipulated in order to “prove” that under no circumstances vaccination could be the culprit.

        Also I read an article that a couple of months before this illness came to their attention a genetically altered moscito was let loose in Brasil. I am sure I could find the article but maybe somebody mentioned it already, I just don’t have time to read all the comments again. So if you want more information I will look for the article.

        Those two points (vaccination and/or genetically altered moscitoes) make a lot more sense to me than some virus that exists for centuries and never were a problem.

  5. It makes more sense that some sort of chemical or pesticide would be the culprit of the high incidence of microcephaly in Brazil compared to a mosquito bite. It’s not surprisingly that the Japanese maker of the chemical is aligned with Monsanto, the top dog of causing mayhem on our beautiful planet. The level of greed is so out of control with companies like Monsanto and the Big Pharmas that humanity is being bombarded at every turn with some kind of event that pushes the masses in a corner of fear which leads to higher profits as the masses move on that fear and adopt the recommendations of those who are on the payroll of those greedy companies.


    It’s a classic case of (Problem ~ Reaction ~ Solution) they create the Problem, wait for the public Reaction, then offer the Solution. Pyroproxyfen is manufactured by Sumitomo Chemical, long-term strategic partners of Monsanto (enough said). These are CRIMES AGAINST HUMANITY and these Scumbag Chemical Companies need to be held accountable for their actions.
