For conventionally grown fruit, (grown with chemicals 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.
A conventionally grown banana would be: 4011
An organic banana would be: 94011
A genetically engineered (GE or GMO) banana would be: 84011
These tips are specially important now that over 80% of all processed foods in the US are genetically modified. Many countries in the European Union have been banning GM products and produce (including Austria, France, Germany, Greece, Hungary and Luxembourg). We say “Eat healthy, buy or grow organic”.
