Roundup weed killer is a glyphosate-containing herbicide manufactured by Monsanto, which was acquired by Bayer in 2018.
Since the introduction of Monsanto’s “Roundup Ready” crops in the 1990s, the use of agricultural-grade Roundup has increased exponentially. In 2012 alone, over 283 million pounds of glyphosate was sprayed on crops across the U.S., including corn, soybeans, and sugar beets, among others.
Today, glyphosate is the most widely used weed killer in the U.S. In fact, roughly half of Monsanto’s yearly revenue comes from their Roundup line of products, but the profitable herbicide comes with a dangerous price.
What Chemical in Roundup Causes Cancer?
The active ingredient in Roundup, glyphosate, was first classified as “probably carcinogenic to humans” by the IARC.
Though the Environmental Protection Agency (EPA) has determined that glyphosate is safe to use, other government agencies are investigating this controversial chemical. For example, the National Toxicology Program (NTP) is currently performing studies to see if glyphosate can cause cancer.
Is Glyphosate a Carcinogen?
Despite contradictory research, the International Agency for Research on Cancer (IARC), the cancer research arm of the WHO, classified the chemical compound glyphosate (the active ingredient in Roundup) as “probably carcinogenic to humans” in a July 2015 report.
According to the U.S. Department of Agriculture, Roundup is the most commonly used herbicide in the country. Further, a 2016 Newsweek report stated that glyphosate was the most widely used chemical for agriculture in human history.
