To protect our health, the U.S. Environmental Protection Agency (EPA) sets maximum legal residue levels for every pesticide, for dozens of crops. But a new study in the respected journal Toxicology has shown that, at low levels that are currently legal on our food, Roundup could cause DNA damage, endocrine disruption and cell death. The study, conducted by French researchers, shows glyphosate-based herbicides are toxic to human reproductive cells.
The potential real-life risks from this are infertility, low sperm count, and prostate or testicular cancer. But, “Symptoms could be so subtle, they would be easy to overlook,” says Theo Colborn, president of The Endocrine Disruption Exchange. “Timing is of critical importance. If a pregnant woman were to be exposed early in gestation, it looks like these herbicides could have an effect during the sexual differentiation stage. They really lock in on testosterone.” The bottom line is more research is needed before we can fully understand the effects of glyphosate exposure.
