so the things i am about to say is a bit long and boring but its imformative and good for your health so share this to others and be alert.

So the game is that people end up buying fruits and vegetables, never ascertaining the Serial digit on fruits like apple, banana or orange. The small stickers or printed codes you see on their skin are called PLU, or Price Look-Up, codes. They can detect whether it's the right type of fruit, if it's organic, or if it's chemically grown. For example, a four digit code beginning with 3, or a four digit code beginning with 4 describe the chemical produce so refrain from buying them as much as you could. A five digit code beginning with 9 is for the organic fruits and grown by organic farming. Therefore you have to buy these also quickly because they are also 100% full of nutrients. Therefore, these codes make the checkout process in these grocery stores run smoothly and correctly in pricing. Though less known, such stickers play a very crucial role in fruit supply chain. But it is a pity that our government has no rule in having serial codes on all edible items.
