Cooked ground beef typically lasts for 3 to 4 days in the refrigerator when stored properly in an airtight container and kept at or below 40°F (4°C). Consuming it within this time frame is recommended to avoid the risk of foodborne illness. Beyond 4 days, the risk of bacterial growth and spoilage significantly increases, making it unsafe to eat. Proper cooking to an internal temperature of 160°F (71°C) and prompt refrigeration are important for maximizing shelf life.

Key Points on Cooked Ground Beef Storage:

• Store in airtight containers or tightly wrapped.
• Refrigerate promptly within 2 hours after cooking.
• Keep fridge temperature at 40°F (4°C) or lower.
• Use within 3 to 4 days for safety and quality.
• Signs of spoilage include sour smell, dull color, and slimy texture.

These guidelines are supported by the USDA and multiple food safety sources.
