An amusing thought but I mean the potato salad deli stuff. Anything prepared on site (in a store or restaurant) doesn't need to disclose ingredients. There's no special exception for bread.
Personally, I prefer my bread to not have plastic labels on it. Besides on the bread itself, where would you even put such a label? The sleve-bags for bread are used for more than just one specific bread, so can't put them there either...
