Proper milk storage is essential to maintain its freshness and safety. Milk should be kept in a refrigerator at a temperature of 32°F to 40°F (0°C to 4°C). It is best stored in its original container to protect it from light, which can degrade its quality. Always check the expiration date and consume milk before it spoils. When storing milk, avoid placing it in the refrigerator door, as this area experiences temperature fluctuations. Instead, place it on a middle shelf where the temperature is more stable. If milk is left out at room temperature for more than two hours, it should be discarded to prevent bacterial growth.
