Is my produce Organic, Traditional, or GMO? - How to tell the difference by the PLU

Have you ever gone to produce section of the grocery store and wondered whether the apple that you have your eye on is GMO (Genetically Modified Organism)? Since, by law, food producers are not obligated to state whether their produce has been raised "traditionally," raised with chemicals and pesticides, organically (though most producers will gladly tell you that their produce is organic), or a GMO product, it is up to us, the conscientious citizens, to wisely choose our produce.
That's what I am here today to tell you how to do. Next time you go to the produce section of your friendly neighborhood grocery store, you should notice a sticker on the produce that contains several numbers. Those numbers are known as the produces PLU (Price Look Up) and it can tell you a lot about how the produce was raised. Most PLU's are 4 digits (for example the PLU of the Cripps Pink Apples is 4130), and this means that the produce was raised "traditionally," i.e. with pesticides. Some produce has a five digit PLU.
Produce that has a 5-digit PLU can mean two different things, depending on the first digit. We'll stick with the example of the pink apple, its PLU being 4130, but if it had a PLU of 94130 (the same 4-digit PLU, but with a 9 in front of it) it would mean that it was an organic pink apple. If the apple had a PLU of 84130 (the same 4-digit PLU, but with a 8 in front of it) it would mean that it was a GMO'd pink apple.
Let's do a quick recap.

• 4-digit PLU (i.e. 4130) = Pesticide raised (traditional) produce
  
  
• 5-digit PLU starting with a 9 (i.e. 94130) = Organic produce
  
  
• 5-digit PLU starting with a 8 (i.e. 84130) = GMO produce
