The US Food and Drug Administration is planning to review data on whether 4-MeI, a carcinogenic chemical, is produced during the time of manufacturing of caramel-colored soda.

A California measure was used to test brands like Pepsi, Coca-Cola, and Malta Goya, out of which, Malta Goya reported ten times more carcinogen than the accepted amount, reaching up to 300 micrograms, Verge reported.
Meanwhile, FDA continues to maintain that there is no reason to believe the compound is unsafe. However, it did say that it will look into the matter.
In 2007, the National Toxicology Program, a branch of the US Department of Health and Human Services had said that the 4-MeI substance that caused cancer in mice could be "possibly carcinogenic" to humans.
