What is the purpose of the Grade A and “USDA” logo on the front panel of the carton?
The classification of an egg is determined by the interior and exterior quality of the egg, according to standards established by USDA. There are many eggs packaged that carry a “Grade A” or “Grade AA” statement, but the USDA shield is additional confirmation to consumers of strict quality standards. Although not required, and certainly more expensive, in-house USDA inspectors provide an independent audit of shell egg quality as part of the full-time quality assurance program.
