(Al Jazeera America)—The most widely used herbicide in the world, glyphosate, the active ingredient in the Monsanto product Roundup, was classified as “probably carcinogenic to humans,” in a report released Friday by cancer researchers affiliated with the World Health Organization.
The International Agency for Research on Cancer (IARC) announced its assessment of glyphosate after convening a meeting this month of 17 cancer experts from 11 countries. They looked at the available scientific evidence on five different pesticides, including glyphosate, to determine whether to classify them as carcinogens. Carcinogens are substances that can lead to cancer under certain levels of exposure.
Glyphosate caused DNA and chromosomal damage in mammals, and in human and animal cells studied in laboratories, the report said. Studies of workers who had been exposed to the chemical in the U.S. Canada, and Sweden found “increased risks for non-Hodgkin lymphoma that persisted after adjustment for other pesticides,” the report said.
