EPA again OKs use of toxic herbicide linked to Parkinson’s disease

Agency's draft report backs paraquat's safety but lawsuit's plaintiffs say EPA ignored evidence of Parkinson's risk

The US Environmental Protection Agency is doubling down on its controversial finding that a toxic herbicide is safe for use across millions of acres of American cropland, despite what public health advocates characterize as virtual scientific proof" the product causes Parkinson's disease.

The agency in 2021 reapproved paraquat-based herbicides for use, but a coalition of agricultural and public health groups sued, charging that the EPA had ignored broad scientific consensus linking the substance to Parkinson's.
