Some egg pacers may follow state standards which meet or exceed USDA standards. Some states may have state seal programs which indicate that the eggs are produced within that state and are subject to continuing state quality checks. All eggs sold at the retail level must meet the standards for Grade B or better. Size and grade are two entirely different factors bearing no relationship to one another. Grade is determined by the interior and exterior quality of the egg at the time the egg is packed.
Size is determined by the average weight per dozen.
