The Venezuelan government has banned Coke Zero from the country and ordered Coca-Cola to remove the no-calorie soft drink from store shelves right away, claiming the beverage contains harmful ingredients.

Health Minister Jesus Mantilla said that the ban was aimed at “preserving the health of Venezuelans,” but he did not specify what ingredients were purportedly harmful.

Neither Coca-Cola nor representatives of its bottler in Venezuela responded to requests for comment on Wednesday.
