Is it safe to eat frozen ground beef that is 3 years old?

It is not recommended to consume frozen ground beef that is 3 years old. Even though freezing can effectively halt microorganisms' growth, the quality and safety of food diminish over time. Long-term frozen storage can lead to deterioration, freezer burn, flavor deterioration, nutrient loss, and potential exposure to bacteria or contamination during handling and storage. The recommended maximum freezing period for ground beef is between 4 and 12 months when stored at a constant temperature of 0°F (-18°C). For optimal quality and safety, it is advised to follow recommended storage guidelines and not consume 3-year-old frozen ground beef.
