Let me start by noting that I know food allergies are (quite literally, sometimes) a deadly serious issue, and that therefore there's a lot to be said for the practice of labeling packaged foods with information about their contents and how and where they're processed.
That said, I was bemused to read the label on a container of cashews the other day--and, mind you, this was a container of nothing but cashews, as in "Ingredients: Cashews," full stop--and discover that there was an allergy information panel alerting potential consumers of these cashews that the package, in fact, CONTAINED CASHEWS.
I'm sure there's either benevolence or litigation behind that warning, but it sort of highlights the idiocy of how we do things here in the good ol' US of A sometimes. Have we sunk so low (again) that our product labels not only have to warn us not to dry our hair whilst in a full bathtub or a running shower and to be aware that the beverage we're about to enjoy is extremely hot but also that our packages of 100% cashews contain cashews? One might've hoped we'd have gotten beyond that point by now.
