## Overview

Paraquat is a restricted-use herbicide. Litigation alleges that occupational exposure increases the risk of Parkinson’s disease, particularly among agricultural workers, applicators, and those living near heavy spraying.

### Exposure pathways and biology

Plaintiffs’ experts have pointed to studies linking paraquat to dopaminergic neuron damage; defendants contest dose, route of exposure, and alternative etiologies such as genetics and aging.

Cases often turn on spray records, applicator licenses, proximity to treated fields, and consistency of symptom onset with exposure windows.

### MDL in Southern Illinois

Federal cases are centralized in the Southern District of Illinois with coordinated discovery into regulatory history, epidemiology, and corporate documents.

Bellwether trials have produced mixed outcomes; remaining cases may settle individually, proceed to trial, or dismiss depending on fact development.
