How long does tofu last outside of refrigerator?

Tofu should not be left outside of the refrigerator for more than two hours, as it can spoil quickly at room temperature. In warmer conditions, this time frame decreases to about one hour. Once opened, tofu should be refrigerated and consumed within a few days for optimal freshness and safety. If left unrefrigerated for an extended period, it's best to discard it to avoid foodborne illness.
