The EPA recently said it will no longer approve product labels that claim glyphosate is carcinogenic to humans

See A Scientific Roundup: The EPA intervenes against California’s rogue cancer regulation. Excerpts:

"In an extraordinary intervention, the EPA recently said it will no longer approve product labels that claim glyphosate is carcinogenic to humans. Glyphosate is the active ingredient in Roundup, the popular weed killer. The herbicide has been on the U.S. market since 1974, and the scientific consensus is that it isn’t carcinogenic in humans.

The letter is a rebuke to California, which in 2015 said it would add glyphosate to its official list of carcinogens under the state’s 1986 Safe Drinking Water and Toxic Enforcement Act, known as Proposition 65. California cited the World Health Organization’s International Agency for Research on Cancer’s finding that glyphosate “probably” causes cancer. "

"EPA’s letter is an attempt to restore science to the glyphosate debate and counter California’s rogue regulation. The letter cites EPA’s extensive review of the scientific literature on glyphosate, as well as the concurring judgments of regulators in Canada, Australia, the European Union, Germany, New Zealand and Japan."
