Pepsi and The Coca Cola Company (NYSE:KO) were both alerted back in 2012 that a certain chemical in the caramel coloring used in their sodas had a possible link to cancer. The chemical, called 4-methylimidazole, or 4-MI is found in the coloring and very high levels of it have shown to be linked to cancer in animals. Following the warning, both companies said in March 2012 that the necessary changes would be made in order to avoid a cancer warning on the soda’s packaging. But now, according to the Center for Environmental Health, Pepsi isn’t keeping its promise to remove the chemical.
This spring, Coke and Pepsi products were tested by the CEH to determine whether they had done their part in ensuring the safety of their consumers. Samples of both the sodas were purchased from California and 10 other states, and while the Golden State’s samples would have allowed Pepsi to come out unscathed, the rest of the samples didn’t fare as well.
Coke is in the clear and consumers should have no fear as nine out of 10 of its soda samples had little or none of the chemical. Pepsi, on the other hand, didn’t post the same results. All of its samples, except those from California, showed evidence of 4-MI.
