It is totally safe, that was the whole point of it.
It only affects plants.
It brakes down into 3 compounds that are also harmless ( one is water ).
There is no way for it to bio accumulate and there is no way for an animal to process it.
If you drink it , you can not adsorb nor digest it so it gets urinated back out.
However if you breathe it in , the particles can get stuck in your lungs, like rubber dust from tyres or pollen from flowers.
In your body your digestion system will recognise it as being foreign and may cause you to throw up.
There is no link between Glyco & non-hodgkinson's lymphoma apart from the fact that several people who came down with Lymphoma had been exposed to Glyco.
They all had been exposed to hundreds of other known castnogens as well.
So the one & one only study deduced that their might be a causal link.
This was not an actual medical study, just a paperwork correlation looking for things that people who had non-hodgkinsons lymphoma had all been exposed to.
They had all been exposed to air , tyre dust, chloro-flourocarbons and a pile of other things as well.
But just a hint is enough to raise doubts in the totally scientifically illeterate and remember Monsanto is the devil and the lawers will get somewhere between 10 % & 50 % of the payout.
In the mean time, the risk adverse government authorities will look at it & decide that they could be held liable ( for some thing that can not happen ) so will ban it because the insurance companies will see it as a reason to quadruple insurance premiums.
