Just got this in email. Is it true? from http://plantea.com apparently.
By reading the little stickers on fresh produce, you can tell if the fruit was genetically modified, organically grown or produced with chemical fertilizers, fungicides, or herbicides. Here's how: For conventionally grown fruit (grown with chemical inputs), the PLU code on the sticker consists of four numbers. Organically grown fruit has a five-numeral PLU prefaced by the number 9. Genetically engineered (GM) fruit has a five-numeral PLU prefaced by the number 8. For example, a conventionally grown banana would be: 4011, an organic banana would be: 94011, a genetically engineered (GE or GMO) banana would be: 84011
The adhesive used to attach the stickers is considered food-grade, but the sticker itself is not.
