For over 70 years now, health agencies in over 90 countries around the world have been assessing and regulating 2,4-D, and they have consistently approved it for commercial use. Through regular evaluations — typically every 15 years — 2,4-D continues to meet modern safety standards. All agencies — including the WHO agency responsible for pesticides — are of one voice: 2,4-D may be used safely according to label directions.
The United States Environmental Protection Agency, with 15,000 experts on staff is responsible for ensuring the health and safety of both people and the environment. It is the primary regulator of pesticides and herbicides in the US.
The Pest Management Regulatory Agency is the division of Health Canada tasked with regulating pesticides and herbicides. It ensures that manufacturers and applicators adhere to strict safety standards to keep Canadians safe.
The World Health Organization is the “directing and coordinating authority on international health within the United Nations’ system.” One of its responsibilities is examining the health effects of pesticides from an international standpoint.

Other World AgenciesCountries all over the world have agencies ensuring the health and safety of the general public.
“The Agency [EPA] determined, based on several reviews of epidemiological studies, in addition to the animal studies, that the existing data did not support a conclusion that links human cancer to 2,4-D exposure.”
United States Environmental Protection Agency
"Overall, the responses observed indicated that 2,4-D is not genotoxic."
World Health Organization
"Health Canada also consulted an independent Science Advisory Panel comprised of government and university experts/researchers in toxicology, epidemiology and biology. The Panel agreed with Health Canada’s assessment that 2,4-D can be used safely when used according to label directions, with some uses requiring additional protective measures."
