(NBC News) The Food and Drug Administration says it is taking a new look at a brown food coloring in sodas and other foods after Consumer Reports said it found higher than expected levels of a potentially cancer-causing agent in some soft drinks.
The group said its tests of soft drinks using caramel coloring show some contain higher-than-necessary levels of a compound called 4-methylimidazole or 4-MEI.
The FDA says there's no evidence the compound is unsafe as used, but a spokeswoman said the agency would look closer after the Consumer Reports complaints.
