What is in spoiled spaghetti?

Spoiled spaghetti itself doesn't have a specific "something" in it. It's more about what happens when pasta goes bad:

* Bacteria: The biggest issue is bacteria growth. This happens especially if the pasta is left out at room temperature for too long. Bacteria can produce toxins that cause food poisoning.

* Mold: You'll see white or green fuzz on the surface of the pasta. Mold produces mycotoxins, which are also harmful.

* Changes in Texture: Spoiled pasta will become dry, crumbly, and possibly sticky. It might have a sour or off-putting smell.

* Changes in Taste: The taste will be unpleasant, possibly bitter or sour.

What NOT to Eat:

* Never eat pasta that smells or looks unusual.

* Don't eat pasta that has mold on it. Even if you scrape it off, the toxins might have permeated the whole piece.

* Don't eat pasta that has been left out at room temperature for too long.

In short, spoiled spaghetti is unsafe to eat because of the potential for bacteria and mold growth.
