Yes. Before there may have been sesame, it was a lottery. Now there definitely is or is not sesame, which is what's important to people with allergies.

Though it's weird that the FDA don't just allow a 'may contain traces' warning, many countries do.

The reason is that such information is useless. If someone has a sesame allergy, they can not eat the food that "may contain traces" anyway. So actually having a definitive boolean _hasSesame is far more useful information, and will lead to less accounts of confusion.

Just as an example, my son's friend is allergic. Can I, as a parent of a friend, give to this child food with the "may contain traces" label? Will every parent of a friend make the same decision? With the new labeling, the answer is much clearer.

Manufacturers going on a sesame flour adding spree to foods that were previously perfectly safe for those kids is going to cause a lot more pain than people irresponsible enough to treat "May contain" as worth risking for kids they don't know well enough to make that call on.

> It’s not that they’ve added sesame where there was none before, it’s that they’re having to declare that sesame might be there

They added it where there was none before. People with allergies to sesame were eating bread at Olive Garden and Chick-Fil-A just fine before this legislation and now they can't.

The FDA always allowed that. But by naming it a major allergen the "Contain" statement becomes mandatory, and the "May Contain" statement doesn't satisfy that.
