Most people don’t pay much attention to the little stickers on fruits and vegetables,
Called a PLU sticker — short for product lookup — they feature a four- or five-digit number that lets cashiers know what the product is and how much it costs.
Sure it’s easy to tell an apple from a grape, but it’s not always easy to discern between the golden delicious and Spartan varieties of apple, which differ in price.
Whether you’re buying an apple in the UK or the USA the PLU codes will be the same as the codes are used worldwide.
By checking the number, you’ll find out if the product is genetically modified, organic or priced with chemical fertilisers, fungicides or herbicides.
