Misconceptions About PLU Codes
It is true that some five-digit PLU codes beginning with “8” are designated for genetically engineered (GE) or genetically modified (GM) produce. However, this designation doesn’t automatically mean a fruit or vegetable is GE/GM and it is not a common practice to use this code for GM produce. It simply means the producer has reserved those numbers in case they choose to use them for GE varieties later. Genetically modified produce is relatively rare in grocery stores.
Farmers commonly grow crops like corn, soybeans, canola, and sugar beets using genetic engineering, but they do not currently modify many popular fruits and vegetables—such as bananas, apples, and oranges. This common misconception about PLU codes leads to unnecessary consumer anxiety. The system is more of a reservation than an indicator. In summary, PLU codes are not a reliable way for consumers to determine if a fruit or vegetable has been genetically modified.
