Well - what we're doing is eating - 'cause that's where the cyanide originates ... from our own saliva. The point I am trying to make is that it is NOT the presence of a chemical per se which makes it a poison, but rather it's the quantity of it which is ingested.
There are lots of chemicals which enter the food chain quite naturally, including heavy metals such as lead and mercury, but as long as these remain in miniscule amounts, then they pose no significant risk to health - so I think we need to keep a more balanced, non-alarmist view regarding potential poisons in food.
The article referenced states that no acceptable level has been determined for the presence of glyphosate in food (including honey) within the US. I think that is the principle deficiency which needs to be rectified, rather than lobbying for a blanket ban on glyphosate. It has it's uses.
