QIs round up toxic to humans

Is round up toxic to humans

AExpert Answer

As a mom, I am concerned about the safety of products as well. As a toxicologist who focuses on pesticide safety, I can tell you that glyphosate herbicides are backed by one of the most extensive worldwide human health, safety and environmental databases ever compiled for a pesticide product. In fact, evaluations spanning four decades, the overwhelming conclusion of regulatory agencies and independent experts worldwide has been that glyphosate, the active ingredient in Roundup® branded agricultural herbicides, and glyphosate-based products can be used safely when used according to label instructions.


This conclusion follows 40-years of evaluating a large number of different toxicology studies. These toxicology studies are required by regulatory agencies, like the United States Environmental Protection Agency (US EPA), for the evaluating the safety of pesticides.


All pesticides are evaluated for acute, sub-chronic and chronic effects. Acute toxicological testing evaluates whether a single high-dose exposure to a substance will produce acute effects. (An acute effect could be anything from a skin rash to death.) Sub-chronic effects are related to several days or weeks of continuous exposure to a substance. Chronic effects occur after a long period (approaching a lifetime) of continuous exposure. Longer-term studies evaluate whether continual exposure to a substance has the potential to cause adverse effects, such as cancer, neurotoxicity, birth defects or reproductive problems.


The U.S. EPA places pesticides in one of four categories for acute toxicity. Category I is considered the most toxic, and category IV the least toxic. Glyphosate is categorized as having low acute toxicity following oral, dermal and inhalation exposure, since all studies are in Toxicity Categories III or IV.


Regulatory agencies, like the U.S. EPA, whose job it is to approve and regulate pesticides, have reviewed and re-reviewed over the past 40 years all the sub-chronic and chronic toxicity studies and have consistently concluded based on a weight-of-evidence analysis of all the data that glyphosate is not carcinogenic and shows no evidence of genotoxicity, neurotoxicity, immune-toxicity, disrupting the endocrine system, reproductive or developmental toxicity and it does not produce malformations. 


It is the evaluation of all these toxicology studies spanning four decades that have been the basis for the overwhelming conclusion of regulatory agencies and independent experts worldwide that glyphosate and glyphosate-based products like Roundup branded herbicides can be used safely when used according to label instructions.

The term “GMO” typically refers to crops or animals that, through genetic engineering, have had a gene (or a few genes) from a different species inserted into their genome. So yes, by design, to improve a crop or animal with genetic engineering, the genome of the new, GE variety has been changed by the addition of new genes(s).     Your question also asks about whether inserting the new gene(s) will “…activate genes…” Some traits in...

No! However, poor nutrition coupled with highly processed foods and a lack of education regarding healthy eating is bad for our kids. As a mother and farmer, I believe the best way to keep my family safe and healthy is to make sure they eat a balanced diet and make good food choices daily. Fresh, healthy ingredients and minimally processed foods that are low in sugar, salt, calories and cholesterol provide kids with the best opportunity for a healthy diet. Agricultural biotechnology...
