The packaging of yogurt is generally divided into bags and boxes, and the storage temperature of yogurt should be maintained between 2 and 6 degrees. The shelf life of bags is relatively short, usually about one week, while that of boxes is about 18 days to 2 1 day.
If you find that the bagged yogurt leaks, you must not drink it. If the yogurt meets the air, it is easy to expire, and drinking it may cause diarrhea.
