On Wednesday, Los Angeles Superior Court Judge Eliha Berk ruled that coffee sellers, including industry leader Starbucks Corp., must have the warning label.. In 2010, The Council for Education and Research on Topics sued Starbucks and 90 other coffee retailers for failing to apply cancer warnings on their products.. The main culprit is acrylamide, a known carcinogen created during the bean-roasting process.
But according to CNBC, coffee companies say removing the chemical would ruin the flavor. Starbucks claimed the levels of the chemical are not harmful and are outweighed by the benefits. Coffee companies have until Apr. 10 to file any objections.
