Decoding Produce Stickers- What do those numbers really mean?

Have you ever wondered what the numbers on the stickers on fruit and vegetables mean? These numbers are the PLUs or price lookup codes that are used by the cashiers to ring up those items. They are not random numbers; they actually have meaning. What do they stand for?
 
            A five digit number that begin with 9 means that the item is organic.
 
            A four digit number that begins with a 3 or 4 means the produce is probably conventionally grown.
 
             For example, lemons grown in the US labeled 4033 are conventionally grown, have good nutrients, but also            come with a host of chemicals.  Lemons coded 94033 are organically grown, and do not have the chemicals               that the conventionally grown ones have.
 
            A five digit code that begins with the number 8 means the item is genetically modified (GMO) and have                     genes from other organisms. These sticker codes are not as common because PLUs are not mandated by                 any governing body, or companies may label these as conventional. Also, genetically modified corn,                           soybeans, canola, cotton, papaya, and squash are now widely sold in the US.
 
Once you understand the codes, you can look at that little label (PLU) and know whether the produce you are about to purchase was treated with pesticides, genetically modified, both, or neither.
 
Food quality is imperative and in prevention of disease.
