Paraquat use in Pennsylvania concentrated in counties with significant row crop, fruit, and vegetable production. Claim risk is correspondingly highest in those counties — though paraquat-exposed claimants live in every PA county.
South Central Pennsylvania row crop belt
York, Adams, Lancaster, Cumberland, Chester, Berks, and Lebanon counties form the south central Pennsylvania row crop belt. Corn, soybean, alfalfa, and tobacco operations historically used paraquat as a pre-plant burndown herbicide. Both farm owners and hired farmworkers have documented exposure.
Northwest Pennsylvania
Erie, Crawford, and Mercer counties have historic dairy and grain operations where paraquat was applied for weed control on pasture renovation and row crops.
Lancaster County specifically
Lancaster County is one of the most agriculturally intensive counties east of the Mississippi. Paraquat use was widespread in tobacco operations, vegetable production, and field corn. Lancaster County paraquat Parkinson's claims are some of the most common in the Philadelphia mass tort program.
Southwest Pennsylvania
Westmoreland, Washington, and Greene counties have a mix of crop and pasture agriculture. Paraquat exposure in these counties typically traces to farm operations and right-of-way maintenance.
Northeast Pennsylvania
Bradford, Susquehanna, Wyoming, and Lackawanna counties have smaller-scale agriculture, but paraquat exposure is documented through both farm work and rail right-of-way vegetation management.
Bottom line for residents of any PA county
If you worked in or near agriculture anywhere in Pennsylvania and were diagnosed with Parkinson's disease, your case deserves a free review. Geography is one factor; documented exposure is the controlling one.
