What interior defect would cause an egg to be considered inedible?

Here are some interior defects that would cause an egg to be considered inedible:

* Blood Spot: A small, dark red spot inside the egg, which is a bit of blood vessel that broke during egg formation. While safe to eat, it can be off-putting.

* Meat Spot: A larger, fleshy mass inside the egg, which is a developing embryo. This indicates the egg was fertilized, and it's best to avoid eating it.

* Green Ring: A green ring around the yolk, which is caused by hydrogen sulfide reacting with iron in the egg. It's safe to eat but may have an unpleasant smell and taste.

* Off Odor: Any strong, unusual smell coming from the egg indicates spoilage. This can be caused by bacteria growing inside the egg.

* Mold: Visible mold on the yolk or white is a clear sign of spoilage and should be avoided.

* Broken Yolk: A broken yolk, especially if it's watery or runny, can indicate spoilage.

* Foreign Matter: Any visible debris or foreign matter inside the egg should be avoided.

Note: It's important to remember that these are just some common indicators. If you're unsure about an egg's edibility, it's best to err on the side of caution and discard it.
