Of course the manufacturer isn't going to implicate themselves in any ill health issues that may be caused by using their product.
Especially if said company is from the USA.
For instance, look at the trauma 245D has caused.. I can remember the rep coming to the farm trying to sell the stuff, he said it was so safe you could drink it. Dear old Granfather calmly said, "go on then" funny enough, the bloke declined. He was never welcomed on the farm again...
And then for years the manufacturing company denied any health risk a or illness linked to the evil stuff. We now know the truth.
So can we actually trust what these companies tell us?
No.

However, after talking to my old friend the gun stock builder I discovered he had a close friend (another stock builder) who died from cancer which was directly linked to some of the ingredients in said product.
Interesting as he had only ever worked with timber, had no contact with any of the chemicals involved except with said product.

If that doesn't make folk wonder then I guess nothing will.

BTW, I agree with your observations re idiots and roundup etc..... Ya can't fix stupid but ya can medicate it
