How to Read PLU Codes
PLU codes can be either four or five digits long. Four-digit codes typically show that someone grew the produce conventionally, which means it might have received treatment with synthetic fertilizers or pesticides. The IFPS website contains the code list so individuals can look up and search PLU codes. These codes are often in the 3000 or 4000 series. On the other hand, five-digit codes starting with the number “9” signify that the produce is organic. Farmers grow organic produce without synthetic fertilizers or pesticides, using only naturally occurring materials like manure for fertilization and plant-based pesticides to control pests.
For example, a PLU code of 4011 on a banana indicates that someone grew the banana conventionally. However, if the code is 94011, it indicates that the banana is organic. Farmers growing organic produce avoid synthetic chemicals but may still use organic pesticides derived from natural sources. For example, they might apply plant-based pesticides like neem oil or garlic concentrate to organic produce.
