plu number
These PLU numbers are the âProduct Look-Up Numbersâ. The leading number gives you useful information, if you know the codeâ¦ I remember the code on fruit and veggies using a simple rhymeâ¦ 8, I hate. Itâs GMO! 9 is fine. Organic. All others, like 3 or 4, are neither GMO or organic. They are conventionally grown.
