Also, questions of exposure are not addressed here. This person was drenched in it couple of times by accident. If I use rat poison for my job vs have it rubbed or consumed in different doses, results can be quite different. Monsanto claims it's safe in any form and quantity but I don't think that's ever been verified. Level of exposure matters a great deal. There is a reason so many cleaning products have warnings on them about keeping them away from the body (though not for cancer)
