What do those little stickers with numbers on your fruit mean? Well, I found out. Those numbers indicate whether the fruit is conventionally or organically grown or genetically engineered! A friend of mine passed on this link to me, so I'm passing it on to you.
"[T]he sticker labels on fruit: The numbers tell you how the fruit was grown. Conventionally grown fruit has four digits; organically grown fruit has five and starts with a nine; genetically engineered has five numbers and starts with an eight."
