Eggland's Best participates in the voluntary USDA program of Grading for quality and egg size, and Eggland's Best production facilities conform to USDA requirements for construction, equipment, and hygienic operation. The USDA Grademark shows that the eggs were graded for quality and checked for weight (size) under the supervision of a trained USDA grader.
Determining the age of an egg is simple with Eggland's Best Eggs. The day of the year that the eggs are processed and placed into the carton must be shown on each carton with the USDA Grademark shield. This is called the "Pack Date.” The number is a 3-digit code that represents the consecutive day of the year. For example, January 1 is shown as "001" and December 31 as "365."
