Do things really go out of date really quickly once opened?

Short answer to your question, no they don't.

Sorry, but I have to disagree.

You may buy pre-packaged cooked meat that has a "use by" date that is 10 days from now, but which says on the packet "once opened, use within 2 days".

Now I would say the 2 days is probably overly cautious, but there is no doubt that the product will start to go off more quickly once opened, if it has been hermetically sealed in a sterile environment. Once you open the product up to oxygen and bacteria, deterioration accelerates rapidly.

It's possible the op has a freezer, but not a fridge?
