Roundup Multiple Myeloma Lawsuit Filed Over Exposure to Weedkiller

According to allegations raised in a lawsuit filed against Monsanto, exposure to the weedkiller Roundup caused an Illinois man to develop multiple myeloma. 

The complaint (PDF) was filed by Glen McNelly in the U.S. District Court for the Eastern District of Missouri on May 15, indicating that Monsanto knew about risks associated with their glyphosate-based herbicide for years, yet failed to warn consumers and actively tried to deceive the public about the safety of exposure to Roundup.

McNelly indicates that he developed multiple myeloma as a direct result of exposure to the weedkiller both during the course of his employment, and while using on his own lawn and garden.

Exposure to RoundUp May Increase Risk of Non-Hodgkins Lymphoma and Other Cancers. Lawsuits Reviewed Nationwide.

At all times relevant to the lawsuit, McNelly maintains that he used the weedkiller in an intended and reasonably foreseeable manner, and was unaware of the link between Roundup and cancer.

“Based on early studies that glyphosate could cause cancer in laboratory animals, the EPA originally classified glyphosate as possibly carcinogenic to humans (Group C) in 1985,” McNelly’s complaint notes. “After pressure from Monsanto, including contrary studies it provided to the EPA, the EPA changed its classification to evidence of non-carcinogenicity in humans (Group E) in 1991. In so classifying glyphosate, however, the EPA made clear that the designation did not mean the chemical does not cause cancer.”

In March 2015, the World Health Organization’s International Agency for Research on Cancer (IARC) warned for the first time that glyphosate contained in Roundup is likely a cancer-causing agent.

The IARC Working Group provided a thorough review of the numerous studies and data relating to glyphosate exposure in humans, concluding that the cancers most associated with the weedkiller include non-Hodgkin lymphoma and other haematopoietic cancers, such as lymphocytic lymphoma/chronic lymphocytic leukemia, B-cell

lymphoma, and multiple myeloma, according to the complaint.

The case filed by McNelly joins a growing number of Roundup lawsuits filed throughout the United States, typically involving individuals diagnosed with non-Hodgkin’s lymphoma following regular and consistent exposure to Roundup as a farmer or agricultural worker. The plaintiffs allege that the manufacturer recklessly promoted Roundup and pushed greater and greater use of the chemical, without disclosing the potential health risks.

Given the similar questions of fact and law raised in complaints filed throughout the federal court system, McNelly’s lawsuit will be transferred to a federal MDL, or multidistrict litigation, which has been established before U.S. District Judge Vince Chhabria in the Northern District of California.

Judge Chhabri is presiding over coordinated pretrial proceedings, and is expected to address the issue of general causation later this year.

Following the MDL proceedings, including potential bellwether trials, if Monsanto fails to reach Roundup settlements or another resolution for the litigation, hundreds of cases may eventually be remanded back to U.S. District Courts nationwide for individual trial dates.

    My mother passedaway in 2017 from Multiple Myeloma. She was an avid gardener and I have no doubt that Round up was the cause.

We pondered what in the world may have caused this horrible cancer. It took me a while but I remember where she may have been extremely exposed to Roundup other than her own personal use in her yard and the exposure in my yard and her grandmother’s. I remembered when I was picking her up from her school in the misfile of a farm field seeing the airial spraying after the crops had been harvested. I was amazed at the fields of crops with no weeds. My Daughter, Anne, passed away on January 25 , 2018 within three 3 years of diagnosis. She was about to become one of the first MM patients to go into clinical trials at Emory using CAR-T cell therapy. Please contact me through email. Would she qualify for this lawsuit, she left behind a 4 year old daughter and it would like to pursue this on her behave. Leigh, Anne’s mother and Olivia’s grandmother

The more I read about roundup and glyphosate, the more disturbing all this is. Even more since glyphosate is now being found in everything - drinking water, meat, fish, and even organic vegetables. There's a good reason glyphosate is banned in Europe and other countries around the world.

Was diagnosed with stage 3 myeloma after his spine fractured because of the lesions all throughout his body. Thank God, he still lives, but undergoes chemo every other week and has for the last two years. Still can't get his M-spike under control but remain hopeful that we'll have a few more years left together. It's very tough to think it may been caused by Roundup; sure wish we could know for sure.

    Does anyone have or know of an attorney who is handling individuals with multiple myeloma in the Roundup lawsuits. If do you know the fee percentage.

    My father used Roundup around his property to try to kill Kudzu. He would use gallons of it every Spring/Summer. He was diagnosed May 2017 with Multiple Myeloma and is undergoing chemotherapy. He feels too sick and too old and tired to "deal with a lawsuit", but I'm not..... I feel that it is my responsibility to pursue this for him, or at least try. I have so many questions.

    I used Roundup for 20+ years in our yard in NY and then for more than 25 years in Orlando on our acre. I always was watchful to follow instructions and now in 2015 after a horridly painful back i was diagnosed with a cancerous tumor which was part of MM. I am presently under a chemo regimen which will continue for the rest of my life.

    I regularly use round up for 18+ years around our acre yard full of landscape. I was diagnosed with multiple myeloma in 2015 at the age of 44. I underwent two stem cell transplant's, a donor from my sister which has put me into remission. This makes me very angry.
