What is the proper storage temperature for milk?

You should always store the milk at 40 degrees Fahrenheit or below in the fridge. Bacterial growth takes place at a faster pace between the temperature of 40 degrees Fahrenheit and 140 degrees Fahrenheit, therefore it is always advised to store milk at a lower temperature to preserve its freshness and quality for a long time.

It is better to store the milk on a shelf of the refrigerator rather than the door as there is a lot of temperature fluctuation at the door of the fridge and that can harm the quality and freshness of milk.

Milk should be stored at the lowest shelf of the refrigerator as it is the coldest part of the refrigerator and has its temperature between 38 °F to 40 °F.

Opened milk lasts for 4-7 days in the fridge if stored in an air-tight bottle or air-tight container at or below 40 degrees Fahrenheit. 

It is worth mentioning that milk can pick up odors therefore it should be stored in an air-tight container or bottle in the fridge. 

Moreover, it should be stored away from strong-smelling food items like garlic, onion, etc. 

Unopened milk has a longer shelf life and an unopened carton of reduced-fat and skimmed milk lasts for 7 days while the whole milk lasts for 5-7 days when stored properly in the fridge at or below 40 degrees Fahrenheit.

Moreover, storing milk in the freezer further increases its shelf life as the cold temperature of the freezer halts the growth of the bacteria in the milk, thereby preserves its flavor and quality for a long time. Milk lasts for about 6 months in the freezer when stored properly in an air-tight container or plastic freezer bag.
