What PLU Stickers Mean
Those stickers reveal if your fruit is Conventional, Organic or Genetically Modified:
Conventional produce gets a four-digit number. This means the produce was sprayed with chemical fertilizers, weedkillers, herbicides or fungicides.
Organic produce gets a five-digit number that starts with 9. These numbers ensure that the produce was not treated with chemicals.
Genetically modified produce have a five-digit code that starts with the No. 8. This is produce that where man has intervened by manipulating the genes to produce a larger or brighter colored food. This produce may have been chemically treated.
