Fruits and Vegetables: How Can I Tell My Produce is GMO?


Ever wonder if the fruits and vegetables you purchase at your local deli or market are GMO? If you’ve ever asked yourself this, you’ll find this tip helpful: finding out if the produce you buy is GMO is easier that it might seem at first glance.

Each type of fruit and vegetable has its own signs of quality that you need to consider before buying; however, nowadays it’s increasingly tougher to tell which produce is organic and which has been genetically modified in some way. However, this simple trick will help you determine if what you’re buying is 100% organic: the PLU sticker.

PLU (or Price Look Up) codes are the 4-5-digit numbers on produce stickers that have been used by supermarkets since the 1990’s. They represent a globally standardized system implemented by the International Federation for Produce Standards (IFPS).

The PLU number indicates produce items based on a number of factors such as commodity, variety, growing methodology (e.g. organic), and size. Numbers are assigned by the IFPS after rigorous quality control at a national and international scale.

The system is based on 4-digit codes that are within the 3000 and 4000 series. The numbers are assigned randomly, that is, each digit does not imply anything specifically, just an overall identification number. As an example, a small Fuji apple has the code of 4129, a large Fuji apple has the code 4132.

Remember this: If the 4-digit number is preceded by a 9, it indicates that it was grown organically. Any 5-digit number that starts with a 9 identifies the produce as organic.
