Is spaghetti with clams in the sauce still good if left out of rerigerator for 12 hours after cooking?

It's not recommended to leave spaghetti with clams in sauce out of the refrigerator for 12 hours after cooking. Here's why:

* Bacteria Growth: Leaving cooked food at room temperature for extended periods allows bacteria to multiply rapidly, potentially making you sick. This is especially true for seafood like clams, which are particularly susceptible to bacterial growth.

* Spoilage: The sauce will start to separate, the pasta will become dry and hard, and the clams may lose their flavor and texture.

For safety and quality, it's best to refrigerate the spaghetti with clams within 2 hours of cooking. You can reheat it thoroughly before eating.

If you're unsure, it's always best to err on the side of caution and throw it away.
