Eggs by the way hens are fed and exploited
There are other numbers that tell us about the animal's offspring:
" 0" which means organic production
"1 " for production in open farms
"2" for industrial buildings closed
"3 " for hens in cages
The following numbers identify the country, city,... where the egg has occurred so you can maintain proper traceability.
Fresh eggs and refrigerated eggs
Consumers can find fresh eggs, which are those without preservation system, that is to say, kept at room temperature. They have been cleaned and only respond to the A category regarding to their quality.
Instead, we can also find some that are kept refrigerated or in lower temperatures near freezing, which meet quality B.
Obviously, the lower the temperature remains the egg, the higher the storage period.
The eggs that match the category C are those which are defective and are used to make the egg or egg products. They are not found directly in the supermarket, just packaged as egg.
Eggs that have their organoleptic properties (taste, texture, smell, color, etc.) damaged or deteriorated can not be consumed.
