If You See This Egg Color Change, Throw It Out
While eggs are endlessly versatile and one of the easiest ingredients to prepare, they can pose a health risk if cooked when past their prime. Raw eggs can be contaminated with harmful bacteria, most commonly salmonella, but you can save yourself from getting sick by examining your eggs closely, including checking the color.
When an egg is cracked, a good one will have a semi-thick, clear white and a vivid orange or yellow yolk, but a bad egg may have a pink, slightly green, or iridescent egg white. If you see any of these shades, you should throw the egg out, since a color change can signify the presence of bacteria that can make you sick.
There are also ways to tell if your egg is bad before cracking it, like a float test, which involves sliding your eggs into a bowl of cold water; older eggs will float. Another option is holding the egg up to your ear and shaking it; if you don't hear anything, the egg is fine, but if you hear liquid sloshing around, the yolk has most likely gone bad.
