Ist leider nicht mehr aktuell, auch wenn die "Quelle" den Blogeintrag erst vor ein paar Tagen geschrieben hat:
"In the future, the IFPS will begin assigning IFPS PLU codes utilizing the 83000 and 84000series; however, unlike the ‘9’, the leading digit ‘8’ will have no significance."
...
"As the adoption of PLU codes has gained traction, the IFPS has committed to transitioningthe previously unused ‘8’ prefix to accommodate an increase in varieties of fresh produceitems as they enter the market.
Though the ‘8’ prefix (83000-84999) was once reserved for GMO produce items, the prefixwas never used at retail. Stripping the prefix of this particular designation will yieldone thousand additional PLU codes to be used in future years. The 83000 series will bereserved for conventionally grown items where the 84000 series will designate thecorresponding organic item."

Also nicht vor dem Präfix 8 fürchten, da bedeutungslos.
