> 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.
