Of all the genetic engineers who have renounced the technology—Arpad Pusztai, Belinda Martineau, Thierry Vrain, John Fagan and Michael Antoniou, among others—Caius Rommens’ story may be the most compelling.
Rommens was director of research at Simplot Plant Sciences from 2000 to 2013 where he led development of the company’s genetically engineered Innate potato. But over time, Rommens started to have serious doubts about his work and worried about potential health risks from eating the GMO potatoes, which are now sold in 4,000 supermarkets in the U.S.
Rommens’ concerns about the GMO potato led him to write a book, Pandora’s Potatoes, which was recently published. The book is a case study on how a scientist’s initial enthusiasm about genetic engineering turns to doubt and fear as he realizes the hazards the technology can create.
