Eggland's Best Eggs are subjected to the most rigorous testing in the marketplace. Each year, Eggland's Best conducts nearly 75,000 laboratory tests to ensure that lower levels of cholesterol and saturated fat and higher levels of Vitamin E, Iodine, and Omega-3 are consistently met. Our scientists also check Eggland's Best yolks for their consistently rich, yellow color, and they check the overall quality of Eggland's Best shells to ensure that consumers are getting eggs with the finest, strongest shells possible. Three independent laboratories confirm nutritional results, which repeatedly show that Eggland's Best eggs exceed specifications. Licensed producers of Eggland's Best eggs have resident graders from the U.S. Department of Agriculture inspecting the quality of our eggs.
