To know if an apple is organic, check the PLU (Price Look Up) sticker on the fruit. This simple trick is used by cashiers and consumers to identify the produce type and how it was grown.
Understanding PLU Stickers
The PLU sticker is a small label found on most individual pieces of produce sold in supermarkets. It contains a four or five-digit code that identifies the commodity, variety, and how it was grown.
As the reference notes, checking the PLU sticker is a straightforward way to get information about your produce.
Decoding the PLU Code
The key to identifying an organic apple lies in the first digit of the PLU code.
- Conventional Produce: A four-digit code starting with a 3 or 4 indicates conventionally grown produce. Most apples you encounter will have a code like 4015 (for a large Gala apple).
- Organic Produce: A five-digit code starting with a 9 indicates organically grown produce. An organic apple, like an organic Gala, would typically have a PLU code such as 94015.
- Genetically Modified (GMO) Produce: A five-digit code starting with an 8 indicates genetically modified produce. While this code exists (e.g., 84015 for a potentially GMO apple), it's rarely seen on apples in most regions as there are currently no commercially available GMO apples in the market that require this specific labeling according to the voluntary PLU system.
Quick Guide to PLU Codes
| First Digit | Code Length | Growing Method | Example (Apple) |
|---|---|---|---|
| 4 | 4 digits | Conventional | 4015 |
| 3 | 4 digits | Conventional | (Less common) |
| 9 | 5 digits | Organic | 94015 |
| 8 | 5 digits | Genetically Modified | 84015 (Rare) |
Note: This system is voluntary but widely adopted by retailers.
Beyond the Sticker
While the PLU sticker is the primary method for quick identification, here are a few other points to consider:
- Store Labeling: Organic produce is usually displayed in a separate section or clearly marked with "Organic" signage or tags on the shelves.
- Certification Seals: Look for official organic certification seals (like USDA Organic in the United States) on the packaging if the apples are pre-bagged or in containers.
- Appearance: Appearance is not a reliable indicator of whether an apple is organic. Both conventional and organic apples can have blemishes, varying sizes, or perfect appearances depending on variety, weather, and handling.
In summary, checking for a five-digit PLU code starting with the number 9 is the most direct way to determine if an apple is labeled as organic according to industry standards.
