In follow up to previous articles, we note that a consumer group last week released a report that alleged that caramel colored sodas (Coke,Diet-Coke, Pepsi and Diet Pepsi) contain levels of 4-methylimidazole (4-MEI) that reached a level of 7 in a million cancer risk. The Center for Science in the Public Interest, claims that the carcinogen forms when ammonia or ammonia and sulfites are used to manufacture the caramel coloring that gives those sodas brown colors. In conjunction with their report the group requested that the Food and Drug Administration revoke its authorization for caramel colorings that contain 4-MEI, and in the interim to change the name of the additive to ammonia-sulfite process caramel coloring or chemically modified caramel coloring for labeling purposes.
Although according to industry experts the amount of soda that would trigger these effects is excessive, Coca Cola and Pepsi recently announced that they were changing their formulas, because of California's Prop 65 law that would require labeling if, as alleged, these products exceed the 1 in 100,000 risk that triggers labeling requirements.
As we noted earlier a sixty day notice has already been served on certain grocers with respect to similar products. The sixty day notice is the first step in the Prop 65 private enforcement process.
