How long is evaporated milk good for?

I have half a can (opened) of evaporated milk that’s been sitting in the fridge for a few weeks. I know it’s milk, and milk goes bad even in the fridge after a while, but I’ll probably use it in a fudge recipe, which will require boiling it. Should I throw it away and get a new can or will it still be ok to use?

Toss it. It’s good for maybe ten days, definitely not ‘weeks’.

These folks say no go:

Once you open the can to use the evaporated milk, you can store covered tightly in the refrigerator for no longer than a week.
