Strong paraquat cases are built on records. The earlier you start gathering them, the better. Here is a working list of the occupational records that matter and where to find them.
Pesticide applicator license records
State agriculture departments maintain pesticide applicator license records, including issuance, renewals, continuing-education completions, and the categories you were certified to apply. Some states maintain records back to the 1970s.
EPA records
EPA maintains some records under the Worker Protection Standard, including pesticide-handler training and re-entry interval documentation, for employers covered under WPS.
Employer payroll and personnel records
Payroll records, time sheets, supervisor evaluations, and personnel files document who you worked for, when, and in what role. Tax records and Social Security earnings records can corroborate when payroll is unavailable.
OSHA and state workplace records
OSHA records, state worker-comp filings, and any incident reports related to chemical exposure all contribute. Even unrelated workplace records can corroborate that you worked in agriculture during the relevant period.
Equipment and purchase records
Receipts for paraquat products. Equipment maintenance records. Sprayer rental records. Co-op purchase records. These document brand and quantity over time.
What to do if records are unavailable
Many older records have been destroyed or were never maintained. Witness statements from supervisors and co-workers, photographs, and your own consistent testimony can substitute. Industrial hygienists can reconstruct exposure from circumstantial evidence.
