If you thought those little stickers on produce were merely there to speed the checkout process for the bored cashier at your local grocery store, you’ll be shocked to know that those annoyingly adhesive (more on that in a minute) stickers actually contain a wealth of information about the produce you’re about to purchase.
Known in the industry as a PLU code, or price lookup number, the digits were developed by the Produce Electronic Identification Board, an offshoot of the Produce Marketing Association. Since introducing the PLU codes in supermarkets in 1990, this produce industry trade-group has tagged more than 1,200 produce items with their labels. In fact, this coding system, which was first introduced in the good ol’ US of A is currently used in Austria, New Zealand and several countries in Europe and applies not only to produce, but also to nuts, dried fruit, herbs and flavorings. Not bad, ey?
