We have all peeled off those oval stickers on fruits and vegetables before eating them, but have you ever wondered what they really mean? The stickers are not only there to help the cashier scan the price.
The PLU code, or the price lookup number on the sticker also stands for the way the fruits or vegetable was produced. In other words, this code tells you if the product is genetically modified, organic or produced with chemical fertilizers, fungicides or herbicides.
1. If there are only four numbers in the PLU, then the product was grown conventionally, i.e. pesticides were used during the cultivation process. The last four letters of the code represent the type of fruit or vegetable you are buying. For example, conventionally produced bananas always have the code 4011 on their label.
2. If there are five numbers, and the first is “8″, then the product has been genetically modified. The label on a genetically modified banana (GE-genetically engineered of GMO) would contain the numbers 84011.
3. If the PLU code contains five numbers, and the first is “9″, the product is organic. Organic bananas are labeled with 94011.
