Ground beef can be safely stored in the freezer indefinitely if kept at 0°F (-18°C) or below, according to the U.S. Department of Agriculture (USDA). However, for best quality and flavor, it is recommended to use frozen ground beef within 3 to 4 months. Beyond this period, the meat may suffer from freezer burn and a decline in taste and texture, although it generally remains safe to eat if properly stored and cooked thoroughly

. To maximize quality when freezing ground beef:

• Wrap it tightly in freezer-safe packaging to prevent freezer burn.
• Label the package with the freezing date.
• Keep the freezer temperature consistently at or below 0°F.

If ground beef has been frozen longer than 4 months, it may still be safe to consume but might have diminished flavor and texture. Freezer burn does not make the meat unsafe but can affect its palatability

. In summary:

• Safety: Indefinite if continuously frozen at 0°F or below.
• Quality: Best within 3 to 4 months.
• Storage tips: Use airtight packaging and maintain consistent freezer temperature.

This guidance helps ensure both the safety and optimal quality of frozen ground beef.
