How long does it take on average for a new GMO variety to be approved by the USDA, FDA and EPA? What are the general steps that are part of this process? Thank you.

According to an opinion piece by Washington farmer Mark Wagoner written earlier this year, it can take the U.S. more than three years to grant approval of a new biotech product. 

  • USDA conducts a mandatory review of GM plants to assess whether or not they will impact the environment and will be safe to grow.
  • EPA conducts a mandatory review of GM plants that are insect or herbicide resistant to assess whether or not they will impact the environment. The EPA also regulates the use of all crop protection products that control weeds and provide protection against insects and disease that are used on crops grown in the U.S.
  • FDA conducts a review to assess if GM plants are safe to eat. All GM crops on the market have gone through this process.


That’s just agency review and approval process in the United States though. As a company, we start thinking about regulatory requirements early in our product development process. We conduct more than 75 regulatory science studies over a five-to-seven year period in order to answer questions like: What is the sequence of the genetic insertion? Does the trait do what we expected? And if so, at what level? Does a plant with this trait work the way we want and grow like normal? 


Researchers also carefully evaluate product safety, verifying that the new GMO product: 

  • Doesn’t introduce any toxins or allergens; 
  • Is nutritionally the same as its non-GE counterpart; and
  • Has no effect on non-target organisms like beneficial insects, birds and other wildlife 


It’s important to note that any new product concept not meeting these standards are discarded and are not pursued for commercialization.


All of these studies are conducted following international guidelines for good laboratory practices and scientific methods, and then the results are peer-reviewed by the multiple authorities in the more than 70 countries where GMOs are grown or imported.

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...

The first use of recombinant DNA technology, was created by Cohen and Boyer in 1972 with E.coli in 1972 and this article explains this advancement in biotechnology in greater detail. Here is an excerpt: “Their experiments dramatically demonstrated the potential impact of DNA recombinant engineering on medicine and pharmacology, industry and agriculture.”   Recombinant insulin was the first commercial product derived from genetic engineering techniques created in 1976 by the...

A gene with a desirable trait can be moved from one organism to another organism as a means to change it. The traditional way is through selective breeding, which is slow, time consuming, inefficient, and transfers more than one gene, so other unexpected and unwanted traits can cause problems. But genes also can be moved in a laboratory, resulting in what has been called a genetically modified (“transgenic”) organism (GMO). GM technology moves only one gene, eliminating other,... Read More
