Zika Virus or Glyphosate Exposure Causing Microcephaly
Is It Zika Virus or Glyphosate Exposure ?
by Jeffrey Dach MD
Agricultural Chemical Exposure with Glyphosate Causes Microcephaly by Upregulating Retinoic (Vitamin A) Signalling
The news media has been reporting the Zika virus as the cause of microcephaly. However, another very likely consideration is exposure to Monsanto’s Round-Up Herbicide, glyphosate, which disrupts retinoic signalling. Microcephaly describes the small head size in babies born to South American Agricultural workers.

Dr Alejandra Paganelli reported in 2010 that “Glyphosate-based herbicides produce teratogenic effects on vertebrates by impairing retinoic acid signaling.” (8) Left image: baby born with microcephaly. News media blames the Zika Virus courtesy of BBC News.
Dr Paganelli concludes: “(congenital malformations) “produced by Glyphosate Based Herbicides are mainly a consequence of the increase of endogenous retinoid activity. ” (8)
Dr Sylvia Lopez
In 2012, Dr Silvia L. Lopez reviewed the effects of agricultural chemicals, glyphosate based herbicides, in human and animal models.(9) She says: “It is very well known that acute or chronic increase of retinoic acid (RA) levels leads to teratogenic effects during human pregnancy and in experimental models. The characteristic features displayed by Retinoic Acid embryopathy in humans include brain abnormalities such as microcephaly, microphtalmia, and impairment of hindbrain development; abnormal external and middle ears (microtia or anotia), mandibular and midfacial underdevelopment, and cleft palate.” (9) Note: Retinoic Acid is Vitamin A Derivative.

Dr Benitez-Leite reported 52 cases of malformations in babies born of women exposed to agricultural chemicals. The congenital malformations observed include anencephaly, microcephaly, facial defects, myelomeningocele, cleft palate, ear malformations, polydactily, syndactily all consistent with the well-known and expected syndrome caused by upregulation of the RA pathway.(10) Left image Monsanto’s Roundup herbicide contains glyphosate.
The Zika Virus is a distraction from the real cause of the problem, the widely used agricultural herbicide, glyphosate. The cause of microcephaly in babies born to South American Agricultural workers is glyphosate exposure which upregulates Retinoic Acid (Vitamin A) and is known to cause microcephaly in animal and human models.

12) Comment by Mark WIlliam Houston on The Scientist
“I find it unusual that the Zika Virus, which comes from Uganda has never caused a single case of microcephaly in a child born in Central Africa. Now it may be argued that the Brazilian Zika Virus is a mutated strain, but, the Zika Virus was first discovered in 1947, in the Zika Forest, Uganda, and as such already has hundreds of different strains. Remember, the Zika Virus has been part of the Zika Forest ecosystem for possibly thousands of years, yet still, there is not a single recorded case of a hominid microcephaly and or a case involving any other mammal the virus has infected.”
