While unpacking groceries, you pull out the bag of apples and decide to eat one then and there. You take it over to the sink, wash it off and — with some effort — peel off the little sticker. Pausing to look more closely at the sticker you wonder, “What do those numbers mean?”
As much as we may dislike them, the stickers or labels attached to fruit do more than speed up the scanning process at the checkout stand. The PLU code, or price lookup number printed on the sticker, tells you how the fruit was grown.
As reported by Maria Gallagher, in the June 26, 2002 issue of the Philadelphia Inquirer, by reading the PLU code, you can tell if the fruit was genetically modified, organically grown or produced with chemical fertilizers, fungicides, or herbicides.
