You know those annoying little stickers on your fruits and veggies? Well, it turns out they actually have a purpose other than being annoying and slowing you down when you are about to chop. I came across a tiny tid bit in Cooking light magazine that explains...
Each produce item in the grocery store receives a four to five digit price look-up code (AKA "PLU"), as determined by the International Federation for Produce Standards. If the item is organic, it will have a five digit number beginning with 9. Conventionally grown produce will have a four digit number, usually beginning with a 4.
And, I also came across this site which is pretty cool.
'Cause knowledge is power! Yeah!
