Ever wonder about your granny (smith's)?

Just read this little tidbit about the mysterious numbers that you always see on fruit stickers:

"[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."

Note to self: avoid 5-digit fruits starting with the number 8. And here I thought (being Chinese) that the number "8" was good luck...
