It's Official: Glyphosate is Now Listed By California As Cancer Causing

Glyphosate, one of the most widely used herbicides in the world, will be added to California’s list of chemicals known to cause cancer under the state law, Proposition 65. The herbicide will be added on July 7 to the list of over 850 chemicals.

Back in March, the California Office of Environmental Health Hazard Assessment (OEHHA) posted a notice online that glyphosate would be added to the Prop 65 list, but stated that the effective date would be delayed due to a lawsuit filed by Monsanto. The company’s challenge to the listing was not successful.

In 2015, the International Agency for Research on Cancer (IARC), an arm of the World Health Organization (WHO), published research classifying glyphosate as a probable carcinogen. The American Cancer Society also classifies glyphosate as a probable carcinogen.

Glyphosate use has dramatically increased since the mid-1990s, according to a 2016 study. Since 1974, over 1.6 billion kilograms of glyphosate has been applied in the U.S., accounting for 19 percent of the estimated global use of glyphosate. Glyphosate use has increased nearly 15-fold globally since the introduction of genetically engineered glyphosate-tolerant crops in 1996. Two thirds of the glyphosate applied in the U.S. from 1974 to 2014 were sprayed in the last 10 years. In just 2014, farmers sprayed enough glyphosate to apply 1.0 kilograms per hectare (0.8 pound per acre) on every hectare of U.S. cropland and almost 0.56 kilograms per hectare (0.47 pounds per acre) on all cropland globally. Genetically-engineered crops account for about 56 percent of the global glyphosate use.

Glyphosate is in U.S. waterways. Researchers from the U.S. Geological Survey (USGS) looked at over 3,000 water and sediment samples and over 1,000 quality assurance samples collected from 2001 to 2010 from 38 states and the district of Columbia. What they found is that 39.4 percent of samples contained glyphosate and its metabolite AMPA (aminomethylphosphonic acid) in 55 percent of samples.
