Glyphosate - Where is it Restricted or Banned in the United States?

Despite the IARC report’s 2015 conclusion that glyphosate is a probable human carcinogen, the U.S. Environmental Protection Agency (EPA) maintains that glyphosate is not likely to be carcinogenic to humans. As such, glyphosate is not banned by the U.S. government; Roundup and other glyphosate-based herbicides are readily available for purchase throughout the country.

However, not everyone agrees with the EPA’s conclusion on glyphosate. A number of cities, counties and even one U.S. state have issued bans, restrictions or warnings on glyphosate as a result of the ongoing health concerns.

 Is Glyphosate Banned in California?

California has not issued a statewide ban on glyphosate. However, on July 7, 2017, California became the first state in the nation to issue a warning on glyphosate by adding the chemical to the state’s Proposition 65 list of chemicals and substances known to cause cancer.

California’s decision to warn consumers about glyphosate was pursuant to the requirements of the Safe Drinking Water and Toxic Enforcement Act, better known as California Proposition 65, a ballot initiative approved by voters in 1986 to address toxic chemical exposure concerns. Prop 65 requires California to publish a list of chemicals known to cause cancer, birth defects or other reproductive harm.
