Glyphosate (Round-Up) is not safe.

Asked May 3, 2019, 6:58 PM EDT

The herbicide Glyphosate in RoundUp is poisonous to the environment, and to humans as well. Why are you recommending it? My daughter used it on our lawn for years and it killed off most of the bees, butterflies, and many other species of insects. Please stop recommending this toxic chemical.

Dear Sir / Madam:
You will find that extension sources may still recommend glyphosate because most world health and pesticide regulatory agencies agree that glyphosate is not likely to be a public health risk. Glyphosate is a registered pesticide in the United States and is legal to use. The US EPA has the authority to register pesticides in the U.S.. On April 30, 2019 the EPA reaffirmed that there are no risks to public health from this active ingredient when used in accordance with the pesticide label. The 2017 ecological risk assessment did identify some ecological risks, so EPA is proposing some appropriate management measures. You can read more about the EPA's recent decision at

Many people are concerned because glyphosate was identified as a probable carcinogen by the International Agency for research on cancer (IARC) a few years back. Just to provide some perspective, IARC has also identified alcoholic beverages and red meat as carcinogens.

The EPA's job is different from IARC's. EPA assesses risk, which must take in account the exposure level in addition to the hazard. EPA does not consider glyphosate a risk to public health because it it is not likely to be a human cancer agent at real world exposure levels. It helps to think of a medicine like common over the counter pain relievers. Take one, good. Take the whole bottle, bad. Similarly, drink a glass of wine occasionally. - Not likely a problem. Drink heavily, and increase your risk of many human illnesses . Hope the analogy helps you better understand the nature of risk, because the same principle applies to glyphosate and pesticides.

Please, don't insult my intelligence. The current EPA has been taken over by an anti-science administration, whose entire agenda is to destroy its effectiveness. Therefore I cannot trust any response that I get from those who act as if it's still cares about the environment. Donald Trump has changed the name Environmental "Protection" Agency into a joke. Roundup is poisonous and should not be used for anything, and you are helping a now-fraudulent organization deceive the American people. Congratulations. By the way; you have glyphosate in your body, as we all do now.
