What are the best conditions under which cream can be preserved? Is it the same for milk?

Milk and cream should always be stored at a temperature between 1°C and 4°C (33.8°F-39.2°F). Cream has a slightly longer shelf life than milk. Once the container is open, cream can be kept for 10 to 15 days while milk can be kept for 7 to 10 days.
