There are several methods and even characteristics you can observe in an egg to know if it is fresh.

For example, on the outside, its shell should be as clean as possible, as it is the egg's protection, and if it is not given the necessary care, it can be a means of contamination.

But currently, technology does wonders, and thanks to it, there is a simpler and more modern way to know the freshness of an egg, where you only need to check a code. 

It is the San Juan Egg Freshness Meter, which you can check online or through its app, in which you just need to follow 3 simple steps: 

1. Open the Freshness Meter
2. Enter the code printed on the egg
3. Check the production date, the farm it comes from, and the preferred consumption date.
