I’ve recently heard that Price Look Up codes starting with the number 8 identify genetically modified food. Is this true? I used to work as a cashier and know that PLU’s that begin with the number 9 are used for organic produce, but I’ve never seen any codes that begin with the number 8. I find it hard to believe after all of the resistance to labeling GMO’s. Any truth to this?

Just about anything including maize or soya is GM. There’s no way a single figure on any code would be identifying GM produce.
