Here we go again: Dr. Oz and glyphosate

We just watched the latest episode of Dr. Oz, and sadly, we weren’t surprised by what we saw.  Just like he did back in April, Dr. Oz used the IARC classification of glyphosate in Category 2A to raise confusion and concern with his viewers.

As a company, we’re eager for folks to know more about how our products help farmers produce food in a more environmentally sustainable way.  We want folks to know that we take safety extremely seriously, and glyphosate has undergone rigorous safety evaluations by regulatory agencies around the world.  Unfortunately, experience has shown us that with its current approach, the Dr. Oz program isn’t the right place for these kinds of detailed and science-based discussions.

In fact, the Dr. Oz program didn’t even reach out to us prior to filming this segment.  When we heard Dr. Oz was having another discussion about glyphosate, we reached out to offer background information and our perspective so that viewers could decide for themselves.  We’d like to share our point of view here as well.

Dr. Oz attempted to argue that the use of pesticides like glyphosate on herbicide-tolerant crops is a reason foods derived from GM crops should carry special labels.  We strongly disagree with this argument as well.  The use of chemical crop protection products is not limited to GM crops.  However, regardless of whether crop protection products will be used on GM or conventional crops, the products undergo detailed regulatory reviews for safety.

Glyphosate-based herbicides have a 40-year history of safe use.  This is backed up by more than 800 studies on glyphosate safety, many conducted by independent researchers.  Regulatory agencies and scientific organizations, like the U.S. EPA, Health Canada and others, have reviewed all the key studies considered by IARC – and more – and arrived at the conclusion that glyphosate can be used safely when label instructions are followed.  Numerous long-term studies of glyphosate have concluded that glyphosate does not pose a cancer risk in humans.

In contrast, IARC took a very different approach and selectively included and interpreted data to classify glyphosate in Category 2A.  The IARC classification conflicts with the overwhelming consensus of regulatory agencies around the world and the findings of thee other WHO programs that have reviewed glyphosate safety.

We welcome your questions about glyphosate, GM crops or any topic related to our business.  Feel free to share what’s on your mind at discover.monsanto.com.  You can also learn more about glyphosate at Monsanto.com/glyphosate or GMOAnswers.com.

  1. While my degree is in neither agriculture nor medicine, I have to fully agree with you that Dr. Oz is frustrating beyond belief in his unwillingness to actually listen to real experts on almost any topic on which he speaks. I’m a dentist, and he even makes MY life more difficult.

    A few years ago, before I really got involved with the skeptical movement, I’d started falling for the fearmongering of Dr. Oz and others, but fortunately, enough red flags got my attention. Eventually, I realized that you guys at Monsanto are just fine, you don’t have any horns or tails, and that conventional/GMO farming is just fine. Even wrote an article about my personal journey: http://www.smilesbypayet.com/2015/04/why-i-dont-buy-organic-food/

    Hopefully you like it. 🙂
