Mutton can be eaten within 1 month after freezing.

Frozen meat is in an ideal state, that is, fresh and pollution-free meat is quickly frozen below MINUS 25℃ and stored at MINUS 65438 08℃, and the shelf life of pork, beef and mutton can reach 2 years. Although the theoretical shelf life of frozen meat is long, the meat bought from the supermarket is easily contaminated by bacteria in the sales process, and it is difficult to ensure the freshness of raw materials.

Therefore, mutton bought from the supermarket should be eaten within 1 month after freezing, and it is best to eat and buy it now. The shorter the storage period, the higher the nutritional value of meat, the better the flavor and taste, and the higher the edible safety.
