Nut Allergy Warning on a bag of Almonds?!

While I was enjoying my bag of "Wonderful Almonds" I also read the back of the package. I wasn't very surprised when I noticed they printed the ingredients on the package, even though the only ingredient is almonds. But I was a little shocked when I read under the ingredients that there is a allergy warning. "Contains Almonds"

Really? You don't say? A bag of almonds contains almonds? And if I have a almond nut allergy I should avoid this product? Well it's a good thing they printed that on their package as they probably avoided dozens of potential law suits, heh. 

Is it that we are really that stupid as a society, or is it the company that just thinks we are so dim witted?
