Eggs sold at a location other than a grower's residence or farm must be washed, graded, sized, properly labeled and kept refrigerated at or below 45° F. Grading information can be found in the USDA's Egg Grading Manual.
Only new or unused cartons can be used to package egg. Cartons cannot bear another producer's or distributor's information. The producer must obtain an egg license issued by SCDA. Unlabeled, ungraded or unsized eggs or eggs off refrigeration are considered adulterated and will be removed from public sale. Selling eggs in those categories or selling without an SCDA Egg License are considered misdemeanors and both carry fines.
