Why is the hamburger I buy at the
grocery store sometimes gray or brown in the middle?
When hamburger meat is ground at the grocery store, the blood in the meat is
oxygenated and turns red. Over time the oxygen is lost and the meat loses it's
"bloom". That happens quicker in the middle of the package, but it is still
safe.
Fresh ground meat should be used within one
or two days.
