If you do not want to freeze your cheese stick, but also really dislike the idea of potentially leaving it outside the refrigerator for hours (or days), there are some ways that can help you feel safer eating cheese sticks. If your cheese sticks are mostly made from softer cheeses, which most are, you are better off keeping them in your fridge at a cooler temperature.

If packaged mild Cheese sticks are still in their air-sealed packaging and at temperatures not too hot, they can be left out of the fridge for about a few days and still be safe to eat. If left out for too long, in heat, or outside of their plastic wrapper, they will rapidly get dried out, slimy, moldy, and are not more fresh or safe to eat.

If you store string cheese refrigerated, away from countertops, it can become too cold on the inside, which is for safety reasons (it could lead to freezer burn).
If it is a shelf-stable string cheese or sticks, it should be okay — sniff and inspect visually first — and keep it covered, too — otherwise bugs or insects may be on it. If you happen to break your cheese wrapper, take off the wrapper and store your cheese in a sealed container or bag. In the event the cheese is not used right away, store in a container or bag that you can seal tight. If you stored your cheese correctly, and it does not show any signs of spoilage, inspect your cheese and consider using it, since it may still be fine a week or two.
Cheese should be stored in an environment with little air contact, which will help to prevent spoilage caused by moisture or being exposed for too long in one period. Whatever type of cheese you have, store it in a refrigerators vegetable crisper, where temperatures are cool and stable.
