A milk marketing campaign by Associated Food Stores has riled several dairy farmers across the Beehive State and caught the eye of a state agency, forcing the Salt Lake City-based grocery cooperative to change its milk ads starting Sunday. At issue is what has been described by the state and irate dairy farmers as a ”misleading” milk ad run by 170 of Associated Food’s 400-plus independently owned and corporate-owned stores, including Macey’s, for the past two weeks.
