Question:

How can you tell if natto has gone bad?


Answers:

Having eaten it for breakfast in Japan many times and being a former chef, I can say this it would take a lot for natto to go bad, as the process to get it to the consistancy it is involved the starches and enzymes in the soya beans to be broken down and fermented, so in a sence it is already bad.

If you were to leave it on the warm counter for 3-6 months and let it get moldy and crust over, perhaps it would be bad then, but if after opening you keep it in the frig in a sealed container, I use a ZipLok bag, I have had a 500 gram pack for 1 month in the frig.
