Vegetarian?

Here's some food for thought. Notice that foods, previously made without peanuts, still had traces of peanuts in them (from being manufactured with foods made with other nuts). Now that allergies are a big thing; we're aware of this -- next thing will probably making vegetarians aware of exactly what traces of animal could be in their food.

Or, is this overly paranoid? Some just put the extra labels to not be blamed if ever an alergic reaction were to occur.
