Roundup

Monsanto/Bayer Roundup (glyphosate) — non-Hodgkin lymphoma

Active MDLIn re: Roundup Products Liability Litigation, MDL No. 2741 (N.D. Cal., Hon. Vince Chhabria). Parallel state-court litigation in California, Missouri, and elsewhere.

Roundup, the world's most widely used herbicide, contains glyphosate — an active ingredient the International Agency for Research on Cancer (IARC) classified in 2015 as 'probably carcinogenic to humans.' Landscapers, farmers, agricultural workers, and home users diagnosed with non-Hodgkin lymphoma have brought tens of thousands of cases against Monsanto and its parent, Bayer.

Background

What this litigation is about.

Roundup was introduced by Monsanto in 1974. In 2015, IARC classified glyphosate as Group 2A — 'probably carcinogenic to humans,' with strongest evidence for non-Hodgkin lymphoma.

The first bellwether trial, Johnson v. Monsanto (California state court, 2018), resulted in a $289M plaintiff verdict (later reduced). Hardeman v. Monsanto (N.D. Cal., 2019) and Pilliod v. Monsanto (California state court, 2019) followed with additional large plaintiff verdicts.

In 2020, Bayer (which acquired Monsanto in 2018) announced an approximately $10 billion global settlement framework covering the majority of pending U.S. Roundup claims and setting up a program for future claims. Additional individual cases have proceeded to trial with mixed outcomes, and litigation continues.

Reported injuries

Complications documented in this litigation.

Non-Hodgkin lymphoma (NHL)

Chronic lymphocytic leukemia (CLL)

A form of NHL recognized in the litigation.

Mantle cell lymphoma

Another NHL subtype tied to glyphosate exposure.

Multiple myeloma

Some claims involve multiple myeloma, though evidence is more contested.

  • You have been diagnosed with non-Hodgkin lymphoma or a related lymphatic cancer.

  • You have pathology and treatment records confirming the diagnosis.

  • You can approximate the years, frequency, and setting of your exposure.
