Fruit and vegetables labelled with a five-digit product code starting with “8” have not been genetically modified, contrary to what has been claimed in posts shared hundreds of times on Facebook since December. While it is true that the prefix “8” was initially intended to label transgenic produce, the International Federation of Produce Standards (IFPS) – which is responsible for establishing Price Look Up (PLU) codes for fruit and vegetables – has never used it in this way. Product codes beginning with 8 will be used to designate new products in the near future. Under Greek law, products containing genetically modified organisms – or “GMOs” – must be clearly labelled as such at the point of sale.
