fruits
The secret is the price look-up (PLU) codes. They're an international numbering standard that identifies each type of produce, so that computerized cash registers can ring up the cost of fruits and vegetables automatically. They're also a powerhouse of information for savvy shoppers. The code indicates whether the item is a conventional, organic or genetically modified (GM) crop.
The codes are based on four-digit numbers for conventional produce, to which an extra digit is added to indicate organic or GM status. If the number is five digits beginning with a 9, then the item is organic. If the item is five digits beginning in 8, then it is a genetically modified crop.
For example, the PLU code for bananas is 4011. If the PLU sticker on the banana bunch reads 94011, then they are organic bananas. If the PLU sticker reads 84011, then the bananas are a genetically modified variety.
