Q. Is it safe to consume crops that were treated with paraquat?

A. Yes. There is very little exposure to paraquat for the consumer of treated crops as the vast majority of paraquat uses do not result in detectable residues in foodstuffs. After reviewing the available information, the US EPA concluded: “there is a reasonable certainty that no harm will result in infants and children or to the general population from aggregate exposure to paraquat dichloride residues. Further, based on the available data, the Agency does not believe that the effects produced by Paraquat would be cumulative with those of other structurally related compounds.” (US EPA, 1997).
