Monsanto Roundup Cancer Cases Centralized in Multi District Litigation

Environmental Torts
Monsanto Roundup Lawsuits

More than 30 lawsuits have been filed around the country against Monsanto Co. The lawsuits allege that the company’s weed killer, Roundup, causes cancer.

What is Roundup?

Roundup is a popular grass and weed killer that is manufactured by Monsanto Co. It is one of the most popular herbicides in the market and has been distributed internationally since the 1970s. The manufacturers indicate that the herbicide contains glyphosphate (41%) and other ingredients that aren’t specifically named on the label. However, it is well known that the herbicide contains POEA. This is a chemical that is soap-like in nature. It is added to the formulation to help glyphosphate penetrate plants.

Roundup is commonly used along with genetically-engineered cotton, soy and corn seeds. These genetically engineered seeds are designed to withstand the effects of the herbicide. This allows farmers to spray their crops with the herbicide without killing them.

Glyphosphate in food

Roundup is the herbicide of choice for farmers across the US and is sprayed on 80% of the crop farms in the country. It also is frequently used on backyard gardens. Many of the crops make it to the table and many more are used to feed farm animals that also make it to the table.

Glyphosphate is a chemical often used in herbicides. The World Health Organization has issued warnings on its use and classified it as a cancer-causing agent to humans. Studies have found residues of the chemical in honey, oats, organic eggs, wheat and other foods.

Roundup and Non-Hodgkin’s Lymphoma

The WHO issued a warning on the use of Roundup and other herbicides containing glyphosphate in March 2015, citing that the chemical was carcinogenic. Although there is limited evidence of this in humans, glyphosphate was shown to cause cancer in lab rats.

Roundup is primarily associated with the development of Non-Hodgkin’s Lymphoma. This is a cancer that begins in the immune systems. It has the potential of spreading to other parts of the body. Several studies have shown high rates of this type of cancer amongst farm-workers exposed to large volumes of Roundup in Canada, the US and Sweden.

Roundup also has been linked to the development of various other types of cancer including Large Diffuse B-cell, cutaneous T-cell and small lymphocytic lymphoma.


In mid-October of 2016, 37 lawsuits against Monsanto that had been filed in courts throughout the US were centralized into a Multi District Litigation proceeding that will be heard in the Northern District of California.
