FDA proposes ban on Orange B, a food dye not used for decades

Federal regulators are proposing to remove another from the U.S. food supply — Orange B, a synthetic color that hasn't been used in the U.S. for decades.

The U.S. said Wednesday that it would seek to repeal the regulation allowing use of the dye approved in 1966 to color sausage casings and frankfurters. No batches of the dye have been certified, or asked to be used, since 1978, FDA officials said.
