Bryan Delaney, Ph.D.

Research Fellow, DuPont Pioneer

I am a toxicologist specializing in the safety assessment of foods and food ingredients with more than 20 years of experience in the field. That’s fitting, considering I have a lifelong love of food! I am a Diplomat of the American Board of Toxicology and a Fellow in the Academy of Toxicological Sciences. My work at DuPont Pioneer is rewarding because as a company, we’re using biotechnology as a tool to improve the most fundamental of human needs – food. I believe we’re making a difference because we’re addressing long term issues like how to feed a growing population on a decreasing amount of land to grow crops.

A: For your first question, the longest duration of animal studies that we (DuPont Pioneer) conduct is 90 days. The duration of the 90 day study is not unique to foods from GM crops as the duration is the same as with many other types of products. The 90-day duration was prescribed by international scientific authorities at the Organization for Economic Co-operation and Development (OECD). In addition to the 90-day studies the registrants of new biotech products conduct, a team of...

A: The longest duration of animal studies that we (DuPont Pioneer) conduct is 90 days, but it’s important to know that the feeding studies are just one part of the comprehensive testing we undertake for each new trait. The proteins that are expressed in these crops are tested extensively with laboratory studies and computer comparisons to make certain that they are not similar to proteins that are known to be allergenic or otherwise toxic. We also conduct an extensive amount of composition...

A: We conduct 90-day rat feeding studies on new biotech traits, which is consistent with the duration of safety studies conducted for many types of products. It’s important to note that this type of study is one component of the comprehensive testing that we conduct. The biotech process, from initial concept to commercialization, can take up to 13 years; more than 50 studies on food, feed and environmental safety are conducted in the regulatory-science phase of the process alone.  ...

A: Thank you for your question. I understand your concerns about safety, and as a toxicologist (who loves food!), I can assure you that safety is a high priority for me, too. The body of scientific evidence overwhelmingly points to the safety of biotech crops for people and the planet. Major scientific organizations and regulatory agencies around the world have reviewed the research on GM crops and reached consensus on their safety. More than 1,000 studies on biotechnology are available at... Continue Reading

A: The research you reference was addressed by the Royal Society, which is a fellowship of the world's most eminent scientists and is the oldest scientific academy in continuous existence.  The Royal Society convened a panel of scientific experts to review the research and found “no convincing evidence of adverse effects from GM potatoes,” due in part to a number of flaws in study design, execution and analysis. You can find the highlights and full repor,t conducted in... Continue Reading
