What can you tell from those numbers on fruit and vegetable stickers?

The price look-up (PLU) code system used by most produce distributors has the side benefit of allowing consumers to identify conventional and organic produce at the grocery store. Even though the defeat of Proposition 37 means that genetically engineered information will not be added to labels at this time, PLU codes do have the potential to identify genetically engineered produce. This video shows you how to read PLU codes to unlock the information that is already right at your fingertips.

How to Use Price Look-Up Codes on Produce

    Using Price Look-up Codes (PLUs), the Nutshell:

  • PLU codes are four digit numbers that identify different types of produce. For example, #4011 is the code for a standard yellow banana.
  • The number 9 prefix added to a PLU signifies that an item is organic. For example, #94011 is the code for an organic yellow banana.
  • A number 8 prefix added to a PLU signifies that an item is genetically engineered (GE). For example, #84011 is the code for a genetically engineered yellow banana.
  • PLU codes and their organic prefixes are in wide use but GE codes are rare at best.
Food Labeling: How to Identify Conventional, Organic and GMO Produce 11 August,2017Mike Kahn

  • I’m still not sure why genetically modified producers don’t want their products identified. If your product is that great wouldn’t you want it showcased?

    • Mike Kahn

      That’s an interesting question. I think the general perception, at least as it was raised by Prop 37, has been that labeling GMOs would calls attention to them as a warning as opposed to a benefit but I could see how others would say otherwise. I wonder if Prop 37 would have been looked at differently if the labeling requirement put the information into the ingredients list instead of calling it out separately on the front of packaging. Thoughts?

  • I look at some of these fruits and just wonder. I’ve already made up my mind on some, but it sure would be nice to know for sure what is causing them to look so sickly. I never thought I’d have to worry about the stuff that comes out of the ground, but after years on a farm it’s easy to see something is seriously not right.

    I’ve never seen a PLU with an 8 prefix in the grocery store. Has anyone investigated that conventional may also be GMO? Or are the bagged unmarked produce the actual GMO?

    What about foods labeled with just four digits starting with the number 4 or the number 3. I heard that 4 digit PLU’s starting with a number 4 means the produce is organic, but just not USDA Certified Organic, and that four digit PLU’s starting with a number 3 were non-organic. Anyone else heard this?

    There is no such thing as an 8xxxx code, never has been.

  • according to the 2015 press release of the ISPS………..

    “Though the ‘8’ prefix (83000 – 84999) was once reserved for GMO produce items, the prefix was never used at retail. Stripping the prefix of this particular designation will yield one thousand additional PLU numbers to be used in future years. This will not in any way impact the current use of the ‘9’ prefix (93000-94999) which will continue to be used to indicate organic produce items.

    “It is important that we make the industry aware of this re-assignment of the ‘8’ prefix well in advance,” said Ed Treacy, chairman of the IFPS Board. “There is more demand for conventional produce PLU numbers and we’ve exhausted every attempt to secure additional number ranges to use. To date, we have never seen the 8 prefix used at retail. This is not a statement on the social or scientific acceptance of GMO items; it is simply that methods other than PLUs are being used to communicate regulatory and other information to consumers.”

    The IFPS does not anticipate issuing PLUs in the newly released 83000-84999 series for some time but it is important for industry to understand the change that will occur in the future.
