A: This is an important question and has been discussed several times on GMO Answers. You might be interested in these graphics briefly outlining the history of crop modification.   According to Dr. Bruce Chassy, professor emeritus of food safety and nutritional sciences at the University of Illinois at Champaign-Urbana, “GM crops have been planted on more than 2 billion hectares by more than 17 million farmers over 17 years in about 30 countries, with no adverse ecological impacts...

A: The simple answer is: The criticism of Séralini’s use of rats is not about the fact that they were Sprague Dawley (SD) rats. It is that the number of SD rats he used was not appropriate to draw the conclusions he did. SD rats are acceptable to use in carcinogenicity tests as long as the experiment is designed to account for the fact that SD rats are known to have a high rate of certain spontaneous diseases (e.g., mammary tumors) (Brix et al., 2005). The more technical explanation is:...

A: Typically, scientists who focus on reproductive and developmental safety look at two different sources of information: animal studies and epidemiologic investigations. In regard to animal data, glyphosate is relatively unique in having multiple independent companies perform reproductive and developmental toxicology studies in rodents and rabbits. These studies show no reproducible reproductive or developmental effects. Most recently, in 2012, a group of toxicologists conducted a detailed... Continue Reading

A: Roundup Ready sugar beets H7-1 was developed by first making a piece of DNA, called an expression cassette, that contains the cp4 epsps gene for tolerance to the herbicide glyphosate, which is the active ingredient in Roundup agricultural herbicides. Using genetic-engineering techniques, that expression cassette is spliced into a plasmid and transformed into Agrobacterium. The Agrobacterium is then added to a petri dish containing sugar beet cells growing in tissue culture. The Agrobacterium... Continue Reading

A: The recent General Mills announcement sparked a lively conversation on GMO Answers. In fact, several experts responded to the announcement that Cheerios will no longer include GM ingredients. To answer your first question about removing GM ingredients, please see an excerpt from a response from Cathleen Enright, executive director of the Council for Biotechnology Information: “We believe food companies have the right to select the ingredients that are best for their markets, just as...
