Hard cheeses can be frozen for up to 3 months according to Consumer Reports. Other types of dairy, including cream, milk, butter and yogurt may also be frozen. All food items should be frozen on or before their expiration date, and some foods may need shaking or stirring once thawed.
Most meat roasts and poultry can be safely stored in the freezer for up to a year, but raw hamburger should not be frozen more than 4 months. Even bread and chips can be frozen for up to six months. All food stored in the freezer should be placed into airtight plastic containers or bags first.
