Beverage manufacturing giant Pepsi might be in a very big trouble. On July 3, 2013, one environmental group claimed that the caramel coloring which is used in Pepsi has a concerning level of carcinogen. The extremely-high level was found even after the company assured that it will change its formula.

In March 2013, California passed a law which mandated that companies which manufacture beverages must add a cancer warning label to the drinks which contain carcinogen. After the passing of the law, companies like Pepsi and Coca-Cola assured that they would adjust their formulas nationally. When the law was passed, necessary changes were made for drinks which were sold in California.

The chemical is known as 4-Mel and can be formed during the cooking process, due to which it might be found in trace amounts in many foods. The Center for Environmental Health tested some samples, after which they found that Coke products no longer test positive for the chemical. However, Pepsi products which are sold outside California did not pass the test.

On the other hand, the company said that the FDA and other regulatory agencies around the world did not find the caramel of Pepsi as unsafe.
