While one study has linked the chemical to cancer in mice and rats, the American Beverage Association, which represents the broader beverage industry, said there was no evidence to suggest humans were at risk, the BBC reported.
Coca-Cola representative Diana Garza-Ciarlante told the AP her company did not feel that Coke, in its original formula, posed a public health risk.
