How long does it take for unrefrigerated lamb chops to spoil?

Raw lamb chops can spoil quickly if not refrigerated. According to the USDA, raw lamb chops should be refrigerated at 40°F or below and used within 3 to 5 days. If you purchase lamb chops that are already ground, they should be used within 1 or 2 days. Once lamb chops have been cooked, they can be stored in the refrigerator for 3 to 4 days or in the freezer for up to 6 months.
