Which grade would an egg fall under with pronounced calcium deposits?

An egg with pronounced calcium deposits falls under Grade B. Grade B eggs are characterized by having noticeable defects that affect their quality, but are still considered safe for consumption. Calcium deposits are one such defect that can occur on the shell surface, often giving it a rough texture. These deposits do not impact the edible quality of the egg, making it viable for sale although not at the highest quality standard.

Grade AA eggs would not display these kinds of defects; they are expected to have clean, unblemished shells. Grade A eggs also should have minimal blemishes or irregularities. The category "Loss or reject" is reserved for eggs that are not fit for consumption, typically due to severe defects or spoiling, which doesn't apply to eggs with only pronounced calcium deposits. Therefore, those eggs are classified as Grade B due to the presence of shell irregularities.
