WASHINGTON — According to a study by consumer advocacy group Center for Science in the Public Interest, high levels of a chemical that causes tumors in animals were found in Coca-Cola Co. and PepsiCo. Inc. soda products, the San Francisco Chronicle reported.
The chemical 4-methylimidazole, which was found in Coca-Cola, Pepsi Cola, Diet Coke and Diet Pepsi, is part of caramel coloring used in the beverages and has been linked to cancer in rodents.
However, the U.S. Food and Drug Administration says there is no reason to believe there is any immediate risk from the substance.
According to FDA spokesman Douglas Karas, a consumer would have to drink more than a thousand cans of soda in a day to match the doses administered in studies that showed links to cancer in rodents.
