Halloween candy could be in for a California makeover. Asserting that the Food and Drug Administration has not moved quickly enough on dangerous food additives, state lawmakers last month passed the California Food Safety Act, which bans four ingredients found in popular snacks and packaged foods — including candy corn and other Halloween treats. Consumer health advocates hope the ban, signed into law by Democratic Gov. Gavin Newsom and set to take effect in 2027, will lead confectioners and food producers to modify their recipes for products sold both in California and elsewhere around the country.
