This is about sesame. Last year or so, the FDA changed the rules about sesame as an allergen. Some bakeries then decided to just slap "may contain traces of sesame" on everything so they didn't have to pay the cost of actually ensuring there's no cross-contamination.
This has significantly harmed consumers who are actually allergic to sesame. Now there's effectively no way to know if a baked product will actually contain sesame, so you either get to eat nothing or take the chance.
It was a clear and flagrant abuse of the "may contain traces" mechanism. The bakeries caused harm for consumers as a way to avoid the coats of doing business safely.
