September 20/Los Angeles/Los Angeles Times -- In what is bound to stoke the debate over the labeling of genetically modified foods, scientists in France have published a controversial study reporting that rats fed corn that was engineered to withstand spraying with the herbicide Roundup developed health problems, including tumors and trouble with their livers and kidneys.
The study, which appeared in the journal Food and Chemical Toxicology, was embraced by opponents of genetically altered foods, including backers of Proposition 37, which if approved by California voters in November would require most foods with genetically modified ingredients to bear a label.
