Cancer-Causing Benzene Found in DrinksMay 19, 2006 | AP A government analysis of more than 100 soft drinks and other beverages turned up five with levels of cancer-causing benzene that exceed federal drinking-water standards, the Food and Drug Administration said Friday.
The companies that make the drinks have been alerted and either have reformulated their products or plan to do so, the FDA said. Government health officials maintain there is no safety concern, an opinion not shared by at least one environmental group.
The five drinks listed by the government were Safeway Select Diet Orange, Crush Pineapple, AquaCal Strawberry Flavored Water Beverage, Crystal Light Sunrise Classic Orange and Giant Light Cranberry Juice Cocktail. The high levels of benzene were found in specific production lots of the drinks, the FDA said.
Benzene, a chemical linked to leukemia, can form in soft drinks containing two ingredients: Vitamin C, also called ascorbic acid, and either of the two preservatives: sodium benzoate and potassium benzoate.
The presence of those ingredients doesn't mean benzene is present. Scientists say factors such as heat or light exposure can trigger a reaction that forms benzene in the beverages.
Federal rules limit benzene levels in drinking water to 5 parts per billion. A limited FDA analysis of store-bought drinks found benzene levels as high as 79 parts per billion in one lot of Safeway Select Diet Orange.
A Safeway Inc. spokeswoman did not immediately return a message left seeking comment.
Dr. Laura Tarantino, director of the FDA's Office of Food Additive Safety, said drinking sodas high in benzene does not pose a health risk.
"This is likely an occasional exposure, it's not a chronic exposure. Obviously, no benzene is something someone wants to have, but the amount of benzene you are getting in a soda is very, very small compared to what you're being exposed to every day from environmental sources," Tarantino said.
However, a spokesman for Environmental Working Group which has accused the FDA of suppressing information about benzene in soft drinks saw the results as a problem.
"FDA's test results confirm that there is a serious problem with benzene in soda and juices," said Richard Wiles, senior vice president at Environmental Working Group.
