You are being extremely naive I'm afraid. People with allergies have to disregard labels every day. Almost everything edible in the UK had these labels. I just looked at the back of the chocolate wrapper I just ate and it "may contain nuts, eggs and peanuts." None of those things are ingredients and the warning is just there to prevent a law suit. My friend who has a severe allergy to eggs and nuts would eat it - otherwise he'd have a very bland diet indeed.
