Does all cheese need to be refrigerated?

Soft cheeses such as cream cheese, cottage cheese, shredded cheeses, and goat cheese must be refrigerated for safety. As a general rule, hard cheeses such as cheddar, processed cheeses (American), and both block and grated Parmesan do not require refrigeration for safety, but they will last longer if kept refrigerated.

REFRIGERATOR. Approximate storage times are: (1) Hard cheeses (block): 6 months, unopened packages; 3 to 4 weeks after opening. Shredded hard cheeses: 1 month after opening. (2) Soft cheeses: 1 week; cream cheese, 2 weeks.

FREEZER. Ricotta, cottage, and cream cheeses do not freeze well. Other cheeses may be frozen for 6 months.
