  • Monsanto's Roundup Herbicide Linked to Leukemia (Multiple Myeloma, Myeloma), Hodgkins and Non-Hodgins Lymphoma, and Parkinson's Disease

    Roundup is the world's most popular herbicide. An herbicide is a type of weed killer and pesticide that has been sold since the 1970s.

    Research has found that Roundup is tied to some life-threatening health risks. Environmental and plant scientists and consumer groups are concerned that glyphosate, the main ingredient in the weed killer, Roundup, may cause serious health issues, such as cancers and Parkinson's disease. Roundup herbicide is made by the Monsanto Company and is used on crops, such as corn and soybeans. These crops are often modified to survive Roundup's deadly effects. According to the Environmental Protection Agency (EPA), United States farmers used about 185 million pounds of glyphosate in 2007, double the amount used six years prior.

    Roundup herbicide exposure may happen to crop workers, applicators who spray Roundup, workers exposed to benches and other woods at large home improvement stores, people who work in smaller nurseries, and people who work at farm stands.

    If you or someone you know has been exposed to Monsanto's Roundup and developed leukemia, lymphoma, or Parkinson's disease, the attorneys at Parker Waichman would like to hear from you.

    Monsanto's FIFRA Stance Can't Nix Roundup Cancer Suit

    In a lawsuit brought against Monsanto—Hardeman v. Monsanto Company et al., case number 3:16-cv-00525, in the U.S. District Court for the Northern District of California—a California federal judge refused to throw out a lawsuit against the weed killer manufacturer on April 8, 2016. The man claims that his cancer is the result of long-time use of the carcinogenic weed killer, Roundup, which is manufactured by Monsanto. The judge rejected arguments that the plaintiff'allegations are preempted by the Federal Insecticide Fungicide and Rodenticide Act (FIFRA), according to Law360.

    Monsanto argued for dismissal of the lawsuit that it claims attempted to hold Monsanto accountable for the man's 2015 diagnosis of non-Hodgkin's lymphoma. The argument failed when presented to U.S. District Judge Vince Chhabria who found that the plaintiff's state's (California) failure-to-warn claims are valid and based on FIFRA, meaning they are not preempted by the Act, as Monsanto claimed, wrote Law360.

    Judge Chhabria did acknowledge that California law "can sometimes" allow a manufacturer to escape liability when a warning would be uncalled for; however, the man's claims arise out of FIFRA's stricter provision that mandates "adequate" warning with no regard to reasonableness, according to Law360. "In this light, it's hard to see how" the plaintiff's "failure-to-warn claims could ‘be construed more broadly than' FIFRA," the judge said on April 8, 2016. "Indeed," the man's "complaint explicitly bases his California-law failure-to-warn claims on Monsanto's alleged violation of FIFRA." Monsanto's argument that the man's failure-to-warn claims are also preempted since the Environmental Protection Agency (EPA) approved Roundup's product labels, Judge Chhabria said that approval does not prohibit private litigation on FIFRA. "The mere fact that the EPA has approved a product label does not prevent a jury from finding that that same label violates FIFRA," he said.

    The judge also rejected Monsanto's claim that the plaintiff cannot continue with his strict liability allegations since his claims that Roundup and its active ingredient, glyphosate, a known carcinogen, are "inherently and unavoidably dangerous." Hardeman alleges Roundup did not contain the warning it should have, according to the order and brought his lawsuit against Monsanto in early February 2016. The lawsuit alleges that Monsanto led to his non-Hodgkin's lymphoma, a cancer that affects the immune system and white blood cells. He alleges that he regularly used Monsanto's Roundup since the 1980s to control poison oak and weeds on his property. He also alleges that Monsanto did not contain the appropriate warnings concerning the dangers the weed killer presented to human health and was generally "unfit and unsuitable to be marketed and sold in commerce," his complaint indicates.

    The plaintiff also claims Monsanto has been aware of Roundup's carcinogenic properties since shortly after its development in 1974 and cited the World Health Organization's (WHO) International Agency for Research on Cancer's (IARC) 2015 study designating glyphosate as an herbicide "probably carcinogenic to humans." Due to IARC's findings, the California EPA followed with an announcement in September 2015 that it would officially list glyphosate as a known carcinogen under California's Safe Drinking Water and Toxic Enforcement Act of 1986.

    Monsanto followed with a lawsuit against the California EPA, arguing in January 2016 Monsanto's right to due process was violated by the proposal.

    Meanwhile, Monsanto faces an array of other lawsuits over the allegedly cancer-causing nature of Monsanto's Roundup, predominantly in California. In at least two cases, Monsanto alleged a lawsuit was preempted by FIFRA; in another case, Monsanto made similar claims. The various plaintiffs are diagnosed with multiple myeloma and non-Hodgkin's lymphoma.

    WHO Report on Glyphosate Cancer Link

    The World Health Organization's (WHO) cancer group, the International Agency for Research on Cancer (IARC), announced in 2015 that glyphosate, one of the ingredients in Roundup, is "classified as probably carcinogenic to humans," according to The New York Times. The agency made the classification based on studies of glyphosate exposure in the United States, Canada, and Sweden since 2001. WHO noted that evidence exists that glyphosate may be cancer-causing to people with non-Hodgkin's lymphoma.

    Glyphosate has been found in food, water, and air following spraying, according to the report. The IARC also noted that the EPA has approved increased tolerance levels for glyphosate in 2013.

    Roundup's main active weed killer ingredient may lead to a variety of significant and deadly diseases, including:

    • Leukemia: Multiple myeloma, myeloma
    • Lymphoma: Non-Hodgkin's, Hodgkin's
    • Parkinson's disease.

    Monsanto Sues California EPA

    Monsanto filed a lawsuit against the State of California's EPA in January 2016. The lawsuit was filed in an effort to prevent the EPA from following the WHO's recommended cancer classification of glysophate, the main ingredient in Roundup. Monsanto claims that the agency "blindly" followed WHO's panel's designation. Monsanto also alleges that California's Office of Environmental Health Hazard Assessment stopped its right to due process when attempting to list glyphosate as known to California state to cause cancer under Proposition 65. The case is Monsanto Company v. Office of Environmental Health Hazard Assessment et al., case number 16-CECG-00183, in the Superior Court of the State of California for the County of Fresno.

    Among other things, Proposition 65, which was passed in 1986, is meant to help ensure pollutants that cause cancer, birth defects, or reproductive harm are kept out of drinking water. The law also states that businesses must post a warning when their operations or products will expose people to chemicals on the state's list.

    Monsanto challenged the legal mechanism associated with California's listing, indicating that the move was "virtually automatic" following IARC's finding that glyphosate is probably carcinogenic. Monsanto also alleged that the portion of California's Labor Code citing IARC's findings is a basis for Proposition 65 listings and is in violation of the California and United States Constitutions.

    Meanwhile, a farmer in Hawaii and a former California field worker cited the IARC's findings in lawsuits alleging Roundup caused their cancers; Monsanto has moved to dismiss these cases.

    Glyphosate's Impact

    In its March 2015 report, the IARC wrote that, "Glyphosate currently has the highest global production volume of all herbicides. The largest use worldwide is in agriculture. The agricultural use of glyphosate has increased sharply since the development of crops that have been genetically modified to make them resistant to glyphosate."

    According to the National Pesticide Information Center (NPIC) in 2015, the herbicide glyphosate is applied to the leaves of plants and is meant to kill broadleaf plants and grasses. Glyphosate is used in agriculture; forestry; lawns; gardens; weeds in industrial areas; and, in some cases, aquatic plants. Glyphosate is also known as a non-selective herbicide. This means it will kill most plants and prevents plants from making certain proteins needed for the plant and microorganism growth. The NPIC is a cooperative agreement between Oregon State University and the EPA.

    How Exposure to Glyphosate Occurs

    The NPIC notes that people may be exposed to glyphosate when using glyphosate-containing products. Roundup is one such product.

    Glyphosate may get on the skin, in the eyes, on the hands, in the mouth, and in the lungs. Exposure may occur by touching the product and then touching other parts of your skin, such as your eyes. Exposure may also occur by breathing in the product when spraying. You may also be exposed by swallowing a product such as Roundup if eating or smoking after spraying without first washing your hands.

    Roundup Cancer Studies

    New studies link Monsanto's Roundup to cancer and Parkinson's disease. A 2011 report published in the journal Parkinsonism Related Disorders discussed a 44-year-old woman diagnosed with Parkinson's disease symptoms after three years of glyphosate exposure when she worked in a chemical factory.

    In 2014, Rodale Wellness wrote about a large increase in non-Hodgkin's lymphoma cases in the prior 30 years. A review, published in 2014 in the International Journal of Environmental Research and Public Health, looked at 44 scientific papers to understand how 80 active ingredients in 21 different chemical classes affected farm workers' risk of non-Hodgkin's lymphoma. The IARC found that exposure to glyphosate doubled a person's risk of developing non-Hodgkin's lymphoma. A 2014 Norwegian study found very high levels of Roundup in U.S. genetically engineered soy crops.

    Glyphosate is so heavily used that it is being found in the rain. The growth is blamed on the increase in genetically engineered seeds, which are needed to survive heavy spraying that may lead to glyphosate toxicity from the weed killer, Roundup. Weeds are becoming resistant to glyphosate due to its overuse and farmers are using more and more of the weed killer to compensate for this resistance.

    "Data has been emerging that point to various health and environmental consequences resulting from glyphosate and Roundup use. These include an increased risk of non-Hodgkin's lymphoma," among others, said Warren Porter, PhD, professor of environmental toxicology and former chair of zoology at the University of Wisconsin–Madison.

    Roundup is sprayed on millions of acres of crops. Scientists remain worried about Roundup's health effects because glyphosate residue may increase the dangers of other chemicals and toxins found on crops. These substances may interfere with bodily functions, potentially leading to conditions such as various cancers—Leukemias and Lymphomas—and Parkinson's disease. According to a study published in the journal Entropy in April 2013, the authors said that, "[Glyphosate's] negative impact on the body is insidious and manifests slowly over time as inflammation damages cellular systems throughout the body." The researchers also said further review is critical and that their study "hit upon something very important that needs to be taken seriously and further investigated." Their study is one of many pieces of evidence to be submitted to the EPA, which is conducting a standard registration review of the chemical, glyphosate, to determine if it should be restricted.

    Other studies have found similar links to Hodgkin's lymphoma and various leukemias, as well.

    Due to Roundup's Cancer Link, France Banned the Weed Killer

    In 2015, France banned Monsanto's Roundup weed killer after the United Nations (UN) classified Roundup's main ingredient, glyphosate, as a probable carcinogen. According to The Independent, French Ecology, Minister Segolene Royal, said, "France must be on the offensive with regards to the banning of pesticides…. I have asked garden centers to stop putting Monsanto's Roundup on sale"

    Andreas Kortenkamp, professor of human toxicology at Brunel University, London, told The Independent in March 2015 that, "Professional gardeners would use industrial strength glyphosate to totally wipe their garden of all plants. Amateur gardeners can also buy it as Roundup in a formulation which is not as strong." Regarding glyphosate toxicity, she adds that, "Anyone who sprays it could get a whiff of it. People should be very careful with this stuff and consider whether they need it. Home gardeners should hand weed to be on the safe side."

    Argentina Town Demands Action Over High Cancer Rates Associated with Weed Killers, Glyphosate

    In May 2015, residents of a town in Argentina demanded action on high cancer death rates seen there. Nearly half of the deaths in recent years were caused by cancer; the national average is 18 percent.

    Residents say the cancers were caused by heavy weed killer use on rice and soybean plots. "There's something going on here," said a local resident involved in the community group, "Todos por Todos," formed after the sudden death of a friend from a brain tumor. Many believe the high cancer rate has to do with weed killer chemicals that are widely used there.

    Entre Ríos, the area involved, recently increased production of rice and soybeans, which are grown with the use of various pesticides and herbicides that maybe harmful to humans. Chemicals are sprayed on fields by special tractors and crop-dusting planes and may drift to nearby areas. Workers are exposed to the chemicals when tending and harvesting crops.

    Reports note that there are limits on how close to neighborhoods farmers may spray, but that these limits are often ignored. Also, there are claims that discarded pesticide canisters have contaminated ground water in some neighborhoods.
