The explanation involves a natural protein in meat called myoglobin.
When myoglobin is exposed to oxygen, it helps give beef the bright red color shoppers commonly associate with freshness.
However, oxygen doesn’t always reach the center of tightly packed ground beef. As a result, the meat inside may appear darker, brownish, or grayish rather than bright red.

Does that mean the beef is safe to eat?
Not necessarily. Color alone cannot tell you whether meat is safe.
