What are grade AA eggs? Grade A? Grade B?

Category: Cooking & Food

Answer:

Eggs are typically graded based upon their internal and external qualities. The grading of all eggs produced in the US is done under the guidance of either federal or state officials that supervise the process based upon strict USDA standards. The grading process involves examining the shell, yolk, and whites of each egg as it passes over a strong white light. This process is known as candling.

The USDA has an optional shell egg grading program that provides and enforces standards, grades, and weight classes. Once the eggs are graded they are put into either 1 of 3 categories: Grade AA, Grade A, and Grade B.

Grade AA Eggs – Eggs in this category must be clean, unbroken, with a normal shape. Air cells can’t measure more than 1/8”. The egg white must be clear and firm and the yolk should be free from any flaws or blemishes.

Grade A Eggs – Eggs in this category must also be clean, unbroken, with a normal shape. Air cells can be larger, up to 3/16”. The egg white must be clear and “reasonably” firm and the yolk should be free from any flaws or blemishes.

Grade B Eggs – Eggs in this category are a little different. They still have to be unbroken but may have abnormal shapes or be stained in some smaller areas. Egg whites are often watery and the yolks will often be dark, flattened, or enlarged. Grade B eggs are not sold to the general public and are often used to create liquid or dried egg products.

    I have to disagree about the sale of grade B eggs to the public. Safeway stores sell grade B eggs. They’re priced substantially less that grade A or AA
