An easy way to double-check whether a piece of produce is truly organic is by consulting the Price Look-up (PLU) code number on the label. The PLU code on an organic product should start with the number 9 and be five digits long; non-organic items have PLUs that are just four digits long.
Yep, and to add to that: 4 digits = "conventional" produce 5 digits, starts with 9 = Organic 5 digits, starts with 8 = Genetically Engineered
hmm idk about this. my friend runs an organic foods store. and sometimes this is not always right. where'd u get this infos?
