Dr. Carrasco of Argentina isn’t alone, not worldwide. As Negin P. Martin, PH.D noted in June in Environmental Health News, studies in other countries show direct effects on humans:

For example, French scientists, Drs. Seralini and Benacour, have published a number of scientific papers about the harmful effects of Roundup and its ingredients on human embryonic and placental cells. A Swedish scientific team lead by Dr. Akerman published an epidemiological study disclosing that exposure to glyphosate is a risk factor for developing Non-Hodgkin lymphoma. Dr. Busbee – an American scientist – demonstrated alterations in estrogen-regulated genes after exposure to dilute concentrations of glyphosate.

Nora Benachour and Gilles-Eric Sralini report in Chem. Res. Toxicol., 2009, 22 (1), pp 97–105 about Glyphosate Formulations Induce Apoptosis and Necrosis in Human Umbilical, Embryonic, and Placental Cells:

We have evaluated the toxicity of four glyphosate (G)-based herbicides in Roundup (R) formulations, from 10⁵ times dilutions, on three different human cell types. This dilution level is far below agricultural recommendations and corresponds to low levels of residues in food or feed. The formulations have been compared to G alone and with its main metabolite AMPA or with one known adjuvant of R formulations, POEA. HUVEC primary neonate umbilical cord vein cells have been tested with 293 embryonic kidney and JEG3 placental cell lines. All R formulations cause total cell death within 24 h, through an inhibition of the mitochondrial succinate dehydrogenase activity, and necrosis, by release of cytosolic adenylate kinase measuring membrane damage.

And it gets even better:

The deleterious effects are not proportional to G concentrations but rather depend on the nature of the adjuvants. AMPA and POEA separately and synergistically damage cell membranes like R but at different concentrations. Their mixtures are generally even more harmful with G. In conclusion, the R adjuvants like POEA change human cell permeability and amplify toxicity induced already by G, through apoptosis and necrosis. The real threshold of G toxicity must take into account the presence of adjuvants but also G metabolism and time-amplified effects or bioaccumulation.

Glysophate makes other chemicals even more toxic, and remember Glysophate doesn’t break down rapidly and tends to accumulate in organisms. Organisms such as you and your children.
