Under what condition can packaged food be stored in ice?

Packaged food can be stored in ice when the container is not subject to the entry of water. This condition is important because allowing water to come into contact with the food can lead to contamination and spoilage. Water can introduce pathogens and harmful bacteria that thrive in moist environments, posing a risk to food safety.

By ensuring that the container remains sealed and protected from water entry, you maintain the integrity of the food, preventing it from becoming wet or contaminated while still keeping it cool. This method of storage is particularly effective for items that need to be kept chilled without direct exposure to water, such as certain types of packaged meats, dairy products, or prepared foods.

For the other options: when the container is opened or placed in direct contact with raw meat, there is a significant risk of cross-contamination. Being completely submerged in ice can also lead to water pooling inside packages, which is not ideal unless specifically designed for that purpose. Thus, the choice that ensures food safety and hygiene while utilizing the cooling properties of ice is the correct one.
