Here's what you need to know about the PLU codes:
1. If the PLU contains only four numbers, this indicates that the produce was grown conventionally, or traditionally, with the use of pesticides. For instance, all bananas are generally marked 4011.
2. If the PLU code contains five numbers and starts with '8', this will indicate that the item is a genetically modified fruit or vegetable, meaning that they have been tampered with in an unnatural way. So in the case of a genetically modified banana, it would be marked, 84011.
3. If there are five numbers in the PLU code, and the number starts with '9', this indicates that the product was grown organically and was not genetically modified. So, an organic banana would be marked: 94011.
What's more? While the adhesive used to attach the stickers is considered to be food-grade, the stickers themselves are not safe to consume.
So, if you are looking to consume fruits and vegetables which are free from pesticides or GMO, buying organic produce is your safest and best bet. Nevertheless, as these items can at times be expensive, a great way to keep costs down is by knowing which fruits and vegetables are generally fine to eat (even if pesticides were used) and which aren't. These are referred to as the Clean Fifteen and the Dirty Dozen. So, which fruits and vegetables fall under these categories? Check out the chart below:
