A: We reached out to Bob Goldberg in the Department of Molecular, Cell and Developmental Biology at UCLA. Included below is his response to this question: “There is no genetically engineered wheat grown anywhere in the world. Wheat was the first crop to be domesticated, ~10,000 years ago, by our ancestors. Gluten is a protein that is naturally found in wheat seeds and is used by the wheat plant when it germinates as a source of carbon and nitrogen for the growing seedling.  Dwarf wheat...

A: First of all, no organisms have ever been modified to produce Roundup (glyphosate). Several crops have been modified with a minimally altered version of one of their existing enzymes (EPSPS) which makes them tolerant to that herbicide, but they don't make it. Second, regulatory agencies around the world don't base their decisions on “anecdotal evidence,” no matter how much is available. They stick to solid science. The consensus among regulators is quite clear that glyphosate has no real... Continue Reading

A: Plants are not "doused" in Roundup or, more precisely, its active ingredient glyphosate.  Relatively small amounts of glyphosate are applied as weeds emerge.  These die and do not compete against emerging glyphosate-resistant crops.  Glyphosate is amazingly non-toxic to humans or any other animals.  Acute effects are seen only at relatively high doses. The LD50 (the dose that kills half of the rats that consume the dose) is about 5,000 mg/kg of body weight.  In other... Continue Reading

A: It is first important to know that pesticides go through a natural degradation process as soon as they are applied. This varies widely, based on which pesticide, but is substantial in all cases.  It is, of course, important to wash fresh fruits and vegetables to remove pesticides, as well as microorganisms, dirt and other sources of contamination.  However, EPA requires data on toxicity and pesticide residues to ensure that concentrations higher than what would normally be in or on...

A: EEPA and FDA require exhaustive data to support the proven safety of any pesticide not only to humans, but also to the environment.  This includes data on wildlife and other non-target organisms.  The active ingredient in Roundup, glyphosate, has been repeatedly demonstrated to be extraordinarily safe to humans and other animals.  It has a mechanism of action that targets an enzyme system that is not present in humans and animals.  With regard to the new use of Roundup in...
