Federal officials say they will conduct yet another study into a food compound that in high doses could be considered a carcinogen.
The Food and Drug Administration says it will look into the use of caramel coloring found in numerous sodas and foods after a Consumer Reports study found it in 12 different brands of soda.
The coloring is a byproduct formed by various chemical compounds.
Previous studies conducted by the FDA show nothing wrong with the coloring, but California lists it as a carcinogen in large amounts.
Soda manufacturers have dialed back the use of the coloring in light of this fact.
Consumer Reports suggests the FDA set a maximum level for the substance in foods, along with listing it on the label if it is included.
The magazine also suggests barring distributors from using the word "natural" if the coloring is used.
