A: I am a physician who has worked on the safety of glyphosate since joining Monsanto 17 years ago. Without a full medical history, it would be inappropriate for me to offer any personal medical opinion or recommendation for treatment. I will come back to your specific question but first I want to address your concern about health consequences of glyphosate.   Glyphosate-based herbicides are backed by one of the most extensive worldwide safety and environmental databases ever complied for...

A: To provide a short answer: There is no evidence of allergic reactions to glyphosate or other components of glyphosate-based formulations from oral exposure (e.g. glyphosate residues on food).  You might have been asking this question because you were interested in food allergies, but since that was not specified I’m going to give a more comprehensive answer.    We do see allergic skin reactions (e.g. contact dermatitis, a poison-ivy-like reaction) following the use of...

A: You mention several topics that have been answered on this website, so I can expand on the topics and link to other resources for additional information.    Glyphosate has a 40 year history of safe use and the safety profile continues to grow as it undergoes continuous (and required) re-registration and approvals in countries across the globe.  In fact, health authorities (e.g. WHO), Scientific experts and communities (e.g. American Association for the Advancement of Science...

A: No.   Assessments by regulatory agencies around the world, recently reiterated by Canada and the European Union, have concluded that glyphosate presents no risk of cancer. An association between reported glyphosate exposure and non-Hodgkin lymphoma (NHL) was suggested in some small retrospective studies, which ask individuals or their surviving family members to recall use of chemicals historically. Other, similar studies have failed to demonstrate an association. More... Continue Reading

A: I have been fascinated by this issue since my days in undergraduate statistical genetics. I assume you want to know about what occurs ‘in the wild’ and the most well-known example is viruses moving DNA to their host cells. But you are probably interested in non-viral transfer.   There are specialized situations in which genetic exchange can, and have, occurred among higher organisms (plants); primarily related to close symbiotic relationships. Genomic studies have found a... Continue Reading
