Stickers on fruit mark

Stickers on fruit mark the country and the producer, but few know what the numbers on the stickers mean. If there are 4 digits and the first is 4, it means that the fruit has been sprayed with pesticides. If there are 5 digits and the first is 9, the fruit has been grown organically. If there are 5 digits and the first is 8, the fruit has been genetically modified.
