> chemicals added to food are banned until proven safe

Is that the case here? Paraquat wasn’t banned for any reason, it just hasn’t been approved yet?

That doesn’t comport with how the word “banned” is usually used.

yes, the companies producing it tried getting it approved, and it was for a bit

and then the approval was overturned as the evidence was crap

so, back to the original state: banned until proven safe

> then the approval was overturned as the evidence was crap

Source? I’m curious for this context.

I think they might refer to the EU approving of paraquat, which was appealed by Sweden and other countries and it was a legal process churning on until 2007 when the presumed link with Parkinson's and other factors led to the decision to ban it.

Do you have a link to this decision? I'm having trouble finding it on my own.

that means it could not be sold as fertiliser since that term is presumably regulated.
