Glyphosate does not bioaccumulate so it won't magnify through the food chain.Studies in animals show that there is minimal retention of glyphosate in tissues, and that those quantities are not harmful. If glyphosate exposure occurs in humans, the body is quite capable of rapidly eliminating it.
As I said before, you eat, drink and breathe much more dangerous chemcials than those found in glyphosate every day. Yet we live longer and healthier lives today than ever before. Fear of glyphosate is intentional. There is nothing in the chemistry of this product that should cause a rational person to fear it.
