ive had some go bad within days and some that has lasted for several weeks and been fine.
I just threw out a block of Daiya Havarti. :( I thought it would make it past the 7 days, but it did not. I didn't want to freeze the block, but I should have cut it into smaller pieces and done so.
you had a block of Havarti that lasted more than a few days without being devoured?! amazing.
