Like snacking on dark chocolate? Then we hope you're not doing it to avoid milk, because the US Food and Drug Administration tested 94 dark-chocolate bars and found milk in 61% of them, Quartz reports—including not just products with descriptions like "may contain milk" or "may contain traces of milk," but ones that claim to be vegan, dairy-free, or lactose-free.
What if the label doesn't mention milk at all? Yep, the agency found milk in 33% of those cases. Of 88 bars that didn't list milk as an ingredient, 51 included milk.
