Milk can stay good in the fridge in an uncovered container for a short period, usually up to 24 hours. However, it's important to note that leaving milk uncovered in the fridge can lead to a few issues:
Absorption of Odors: Milk can absorb odors from other foods in the refrigerator, which can affect its taste and quality.
Contamination: Leaving milk uncovered increases the risk of contamination from airborne particles, bacteria, and other microorganisms present in the refrigerator.
Loss of Freshness: Uncovered milk can lose its freshness more quickly due to exposure to air, which can cause it to take on a "fridge taste" or become stale.
To maintain the best quality and extend the shelf life of milk, it's recommended to keep it in a tightly sealed container or its original packaging. This helps to preserve its freshness, prevent contamination, and minimize any absorption of unwanted flavors or odors from the fridge.
