Which of the following foods can be stored in water and/or ice?

When storing food to maintain its freshness and safety, certain items can be kept in water and/or ice to effectively control their temperature and prevent spoilage. In the case of milk, it is important to keep it cold, and immersing it in water or ice helps to maintain a consistent low temperature, which is crucial for preventing bacterial growth. Refrigerated milk is best stored at or below 40°F (4°C), and using water or ice is an effective way to achieve this when refrigeration isn't immediately available or when transporting.

While vegetables, cheese, and seafood may also have specific storage guidelines, they do not have the same necessity for being submerged in water or ice as milk does. Vegetables can typically be stored dry in a cool place, while cheese has its own recommended refrigeration methods and may not require direct contact with water. Seafood can be stored in ice to keep it fresh, but it often is kept in the refrigerator rather than submerged in water. Therefore, the safest and most effective storage method for milk is indeed utilizing water and/or ice to ensure it remains within safe temperature parameters.
