How long does ground beef last after being frozen and thawed? Ground beef that has been defrosted in the fridge can be kept for an additional 1 to 2 days in the refrigerator before cooking; ground beef that was thawed in the microwave or in cold water should be cooked immediately.
Fresh ground beef goes through a number of color changes during its shelf life. These color changes are normal, and the ground beef remains perfectly wholesome and safe to eat within 1-2 days of purchase.f ground beef is refrigerated promptly after cooking, it can be safely refrigerated for about 3 or 4 days. If frozen, it should keep its quality for about 4 months. When reheating fully cooked patties or casseroles containing ground beef, be sure the internal temperature reaches 165 F or it is hot and steaming.
