Cheese maker Cabot Creamery has dropped the word ‘‘Vermont’’ from its label because of concerns over accuracy in advertising. A Cabot official told Vermont Public Radio that a discussion with the state attorney general’s office prompted the change. State rules say dairy products labeled ‘‘Vermont’’ have to be made in the state and get 75 percent of their milk in Vermont. Cabot’s butter is made in Massachusetts, with some cream from New York and New England. Assistant Attorney General Elliot Berg said Cabot could use Vermont on its label but would also have to list where the milk is from.
