The big boogieman is Roundup® – the classic name for the generic glyphosate. It is a widely used herbicide. Without such herbicides crop production would be severely curtailed. However, the EPA and others repeatedly have tested glyphosate and found it to be safe. Glyphosate deteriorates rapidly especially in soil and has a half life that is often less than three days.
Glyphosate has been around for more than 50 years. It is widely used to control weeds, to kill unwanted grasses in preparation for replanting, and it is used sometimes to kill crop plants faster so they dry quicker and can be harvested sooner. Only in this last application could glyphosate could even be detected in foods.
Glyphosate and 2-4-D are two products that are less regulated than many other more toxic products. Therefore, they are more widely used and widely available. In some states you do not need an applicators license to purchase and use either one.
While the chances of being killed by a cow is never zero, and perhaps the chances of being killed by Roundup® is never zero, it is far more dangerous using other more toxic chemicals.
The sad part is the internet is full of misinformation about the toxicity of glyphosate and large settlements have been made to people who claim they were harmed by Roundup®. But juries are not biochemists. And “experts” are bought and paid for by tort lawyers who are making millions suing Bayer who owns Roundup®.
And the hysterics practiced on the internet by pseudoscience is hard to overlook. Juries look sympathetically upon people with injury even when the source isn’t what is claimed nor can be verified even if it is. But both the National Institute of Health and the EPA agrees that Glyphosate is safe when used as directed and no farmer has an incentive to overuse expensive herbicides.
