How and Why are Eggs Graded?
Why Are Eggs Graded?
All eggs are inspected before they are labeled and sold in stores. If an egg producer pays the USDA for the additional quality and sanitation inspection, then they will receive a grade. They can then display this shield, as shown below, but with the appropriate grade filled into the blank space. This shield can be displayed on their carton.
What are the Possible Grades for Eggs?
AA is the highest grade possible for an egg. These eggs contain firm whites and round yolks.
Grade A eggs are nearly as good as grade AA. The grading scanner can detect the slight differences between these eggs and the grade AA eggs. But, these differences are so minor that humans may not notice any difference from the grade AA eggs.
These eggs are inferior, as their grade suggests. The whites are thinner, the yolks are flatter and the shells are discolored.
Grade B eggs are most commonly used to make liquid egg products and won’t normally be found at the grocery in their original egg form.
Which grade is the best choice?
That depends. For everyday use, and the most likely choice contained on the grocery display, the best choice is grade A. If the egg is the center attraction on the plate, especially for a fine dining experience, then the best choice would be the grade AA egg. These eggs will carry a higher price tag, but not necessarily a greater value.
