If you have ever noticed the numbers on the bottom of a milk package, you should know that they are not put there by accident or randomly, and there’s a meaning behind them that not many people know about. The numbers that are found on the package of milk vary from 1-5 (1 to 6 in some countries). There are even 2 secrets behind these numbers. The first secret that scared many people is that the number stands for the number of milk’s usage date, more precisely, how many times it has expired and the milk was reprocessed by the manufacturers.
The worst part is that this reprocessing of milk is regulated by law. The expired milk is reprocessed at a temperature of 190 degrees C and is then brought back in the markets and grocery stores. As you can realize on your own, the manufacturers are allowed to reprocess the milk up to 5 times, but they must print the exact number of how many times it is reprocessed.
Thus, at the bottom of the milk package you can find printed numbers, 1,2,3,4,5 and 6, but you can also notice that one of these numbers is missing. The missing number actually shows how many times the milk was reprocessed. For instance, you see the numbers 12346, and you can notice that number 5 is missing. This means that the milk is reprocessed exactly 5 times. On the other hand, on some packages you will see just one number, which means that this number represents exactly the same thing.
Very often manufacturers tend to combine these number on the boxes, so a number that is missing from a package can be found on another package. Some people believe that these numbers stand for the number of times the cartoon is recucled.
Nevertheless, in many countries the reprocessing of milk is legal, and this is a fact that confirms the abovementioned.
