How to Document Roundup Exposure for Your Case

If you are considering a lawsuit after being diagnosed with Non-Hodgkin’s Lymphoma (NHL) following Roundup use, one of the most critical parts of your claim is proving your exposure to the product. Strong documentation helps establish the link between Roundup and your illness (causation) and can impact the value of your case.

Starting this process now, while memories are fresh, is one of the most powerful steps you can take. At Walch Law, we help our clients build this evidence, but here is a guide on how you can start documenting your Roundup exposure today.

Build a Detailed Exposure Timeline

Your memory is the foundation of your case. Create a written timeline that covers every period of your Roundup use, both at home and at work. Be as detailed as possible.

Dates: When did you start and stop using Roundup? Note any gaps.
Frequency: How often did you spray? (e.g., weekly, monthly, seasonally)
Duration: How long did each application take? (e.g., 30 minutes, 2 hours)
Locations: List every property where you used it (your home, a second property, specific job sites).
Application Method: What kind of sprayer did you use (handheld pump, backpack sprayer)? Did you mix concentrates or use pre-mixed versions?
Conditions: Did you notice getting spray on your skin due to wind? What kind of personal protective equipment (PPE), like gloves or a mask, did you use, if any?

Gather Proof You Purchased and Used Roundup

Physical proof is essential. Search through old files, digital records, and your garage for any evidence that you bought and used Roundup.

Receipts and Invoices: Check for old paper receipts or digital invoices from retailers like Home Depot, Lowe’s, Amazon, or local hardware stores.
Bank or Credit Card Statements: Search your statements for purchases from stores where you likely bought Roundup.
Product Photos: Take pictures of any old Roundup containers or labels you still have, even if they are empty. The storage area where you kept the product can also be photographed.
Employer Records: For occupational use, gather work orders, landscaping contracts, pay stubs, or safety training logs (MSDS/SDS).
Witnesses: Coworkers or neighbors who saw you using the product can provide valuable statements.
Personal Records: Look through old calendars, texts, emails, or even social media posts that might mention yard work or spraying weeds.

Document Key Medical and Personal Information

Connecting your Roundup exposure to your NHL diagnosis is key. Organize your health information and document the impact on your life.

Diagnosis Date: Note the exact date you were diagnosed and the specific subtype of your cancer (e.g., NHL, CLL).
Medical Records: Keep copies of all pathology reports, imaging scans, and treatment timelines. We will retrieve the full certified records, but having your copies is a great start.
Symptom Journal: Write down how your illness and treatments have affected your daily life, work, and family. This helps document your pain and suffering.

How to Preserve Your Evidence

Organize your documents in a binder or a dedicated cloud folder. Date everything you can and make backups. Do not throw away old Roundup containers. Importantly, avoid making public statements about your case on social media, as the defense can use these posts against you.

What to Send Your Lawyer First

You don’t need to have everything perfectly organized to have a consultation. A great starting point is to send your attorney:

A one- or two-page summary of your exposure timeline.
Your top 10-15 pieces of evidence (like key receipts or photos).
Information on your health insurance.

From there, our legal team will handle the formal process of retrieving medical records and building the comprehensive evidence file needed for your case. Or send nothing at all and just give us a call. The best California Roundup law firm will know how to get what they need.
