Is there a difference in how to store something that was frozen that has been cooked versus how to store something that was fresh and has been cooked? There are many questions on here about how long you can store cooked food, and I have been using StillTasty for more specific answers following some of the comments.

However I notice that StillTasty has information listed for many foods for "Fresh, Cooked", "Fresh, Raw" and "Commercially Frozen".  Is there a difference in storage of  "Fresh, Cooked" food and food that was frozen and thawed before cooking?  Or is this just an oddity of their descriptions?

Edit: Assuming the thawing and cooking has been done thoroughly to "safe temperatures".
If I'm understanding your question correctly, there is no difference in storage time. Regardless of whether the food was fresh or frozen &amp; thawed, once cooked, storage time is the same.
