Can't drink it. The shelf life of milk powder is different, most of it is 18 months to 24 months, which refers to the shelf life marked on the milk powder can, and the shelf life of the opened milk powder is one month, one month can not be eaten and can not give the baby to eat, expired milk powder is bad for health. Milk powder is disinfected, sterilized and repackaged, beyond the shelf life or open not eaten, bacteria will exceed the physical and chemical indicators and health indicators, there will be diarrhea and other uncomfortable symptoms, severe cases will appear vomiting and other poisoning symptoms. So make sure you eat it within the expiration date.
In fact, I personally think that the expiration of food is in a sense to see whether the appetite has deteriorated, such as cake, bread and other finished products expired but not deteriorated is edible, but the deterioration of milk powder such as high protein food is not judged by the naked eye, personally feel that for their own safety or not to drink, after all, we do not know whether there is high protein products in the milk we drink?
Of course not! Especially the baby, the milk powder has not been drunk for a month, do not give the baby to drink.
