I just cracked an egg to make breakfast and saw this red spot in the yolk. It really grossed me out and now I’m wondering if I should toss the whole carton or just scoop it out and cook it anyway. Wha

of blood or tissue can become incorporated into the egg, presenting as a red or brownish spot within the yolk.

Blood spots are more likely to appear in brown eggs than in white ones, simply due to differences in how they are processed. The USDA estimates that less than 1% of eggs will have visible blood spots. Modern egg production facilities employ candling—a process where eggs are passed over a bright light source—to detect and remove eggs with such spots, but some can still make it to market.
