How can you tell if your fish sauce is bad?

This isn’t to claim that fish sauce is always good, whether it’s before or after the expiration date (though you should always refrigerate it after opening). Mold or yeast can grow on the inside surface or lip of the bottle where there is excess moisture and less salt, resulting in color changes or the development of “off” flavors. These growths are usually harmless, but as with any food, if it looks strange, smells strange, or tastes strange, throw it out.
