Frozen meat is typically stored at minus 18 degrees Celsius, where bacteria do not multiply.
This means that, in principle, the meat remains safe for a long time, according to Microbiologia Italia.
However, the quality gradually changes. Fat can become rancid, and water in the meat forms ice crystals that affect its structure.
If the temperature fluctuates, the damage can become more significant.

Proper storage
How the meat is packaged is important. Airtight packaging reduces drying out and protects against freezer burn.
At the same time, the freshness of the meat before freezing plays a role in how well it keeps.
Research from ScienceDirect shows that both freezing and thawing affect taste and texture.
Signs of deterioration may include changes in color, an unpleasant odor, and liquid released after thawing.

Differences between types of meat
Not all meat keeps equally well. Guidelines from the USDA show that ground meat should be used within a few months, while whole cuts of beef can last up to a year under good conditions.
Poultry often has a longer shelf life, while fatty meats such as pork should be used sooner. Processed products have the shortest storage time.
Although meat can remain safe to eat after a long time in the freezer, it is the quality that ultimately determines how long it should actually be stored.
