How long does cheese last in the fridge?

Cheese lasts from a few days to several months in the fridge, depending on type; soft cheeses (brie, fresh mozzarella) last about a week, semi-hard (Swiss, Colby) 2-3 weeks, and hard cheeses (cheddar, Parmesan) 3-4 weeks after opening, though unopened hard cheeses can last months.

How do you know if cheese has gone bad?
