LOS ANGELES—Starbucks Corp and other roasters and retailers must serve up a cancer warning with coffee sold in California, a Los Angeles judge has ruled.
Superior Court Judge Elihu Berle in a ruling published on May 7 said that Starbucks and other coffee sellers did not show that the risk from consuming acrylamide, a possible cancer-causing byproduct created during coffee roasting, was offset by benefits from drinking coffee.
