How to tell if a fruit or vegetable is organic or conventionally grown - PLU Codes

Have you ever wondered why there are stickers on your produce and what they really mean?
Price Look-Up codes, or PLU codes, are identification numbers put on produce and other products to make check-out at stores faster and more accurate. You’ll be surprised to know that those stickers can also tell you whether or not a product is organic or conventionally grown.

The first step is to count the number of digits on the sticker.

  • A conventionally grown product (grown with chemical assistance) will have a 4 digit PLU code. (Example: conventionally grown Red Delicious apple: 4015)

  • An organic product will have a 5 digit code starting with the number 9. (Example: organic Red Delicious apple: 94015)

I recently saw PLU numbers at a local Whole Foods beginning with #2 and #3 - I don't recall if they were four or five digits. I didn't have time to ask anyone at the store what PLU's beginning with 2 or 3 meant.

Do you know?

"A four digit code beginning with a 3 represents produce that was irradiated, or exposed to radiation to kill microorganisms."
