However, choosing eggs should be a more informed process, because behind every carton lies a world of quality, farming methods, food safety, regulations, and environmental sustainability.<br>Understanding how to read the codes printed on the shell, where the eggs come from, and what differentiates the various types is essential for making responsible and informed purchases.<\/p>\n\n\n\n<p>We\u2019ve decided to break down all the main aspects: what the numbers on eggs mean, which controls are carried out, how to distinguish farming methods, what information is mandatory, and how to recognize a truly high-quality product.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The Code Printed on the Shell: the Egg\u2019s \u201cIdentity Card\u201d<\/strong><\/h2>\n\n\n\n<p>Every commercialized egg must have a code printed on its shell. This code tells you exactly where it comes from and how the hen was raised.<\/p>\n\n\n\n<p>The code follows a mandatory structure established by <strong><a href=\"https:\/\/agriculture.ec.europa.eu\/farming\/animal-products\/eggs_en\" target=\"_blank\" rel=\"noopener\">European Union regulations<\/a><\/strong>, and consists of several parts.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1) The Initial Number: Type of Farming Method<\/strong><\/h3>\n\n\n\n<p>It can be:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>0 = organic<\/strong><\/li>\n\n\n\n<li><strong>1 = free-range<\/strong><\/li>\n\n\n\n<li><strong>2 = barn-raised<\/strong><\/li>\n\n\n\n<li><strong>3 = caged<\/strong><\/li>\n<\/ul>\n\n\n\n<p>Let\u2019s look at them in detail.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>0 \u2013 Organic Eggs<\/strong><\/h3>\n\n\n\n<p>Hens live outdoors, eat organic feed, and have greater freedom of movement.
