Unopened unrefrigerated kraft shredded cheese
The cheese will not be safe to eat if it has been at room temperature for two weeks. On the package, it should say "KEEP REFRIGERATED". Hy-Vee states the food should be refrigerated here. The  note is there for a reason, the cheese will spoil if at room temperature for too long.

Kraft includes the note because they know it is likely if someone doesn't keep the shredded cheese refrigerated, the person could get sick and sue them for not disclosing it needs to be refrigerated.

It's certainly possible you won't get sick if you eat it. But two weeks is a long time and I recommend not eating it.
