About a half-dozen activists protested Tuesday near the world's largest cereal maker's Battle Creek headquarters to demand it stop using genetically modified crops. Margulis led activists into Kellogg headquarters in an unsuccessful effort to meet with chief executive Carlos Gutierrez. More protests against other companies could be in the works, Margulis said. The U.S. Food and Drug Administration has found no particular problems with genetically modified agricultural products. Kellogg spokeswoman Chris Ervine said the company has no plans to stop using genetically modified crops in its domestic products.
Supporters say genetic modifications help protect crops from insects and other problems.
Detractors say too little testing has been done to know if they are safe.
