Moldy yam breaks are recommended to be discarded immediately and should not be eaten.
Yam is rich in starch and dietary fiber, and its composition is conducive to the propagation and growth of mold. When signs of mold are visible to the naked eye, the entire yam may be contaminated with mold. Even if the moldy part is cut away, the remaining part is likely to have mold reproduction. Therefore, once signs of moldy yam are observed, it is advisable to discard it immediately and not to eat it again to avoid damage to health.
Any food that is moldy and spoiled should be discarded immediately and not eaten again. In particular, moldy rice, noodles, nuts, oil and other foods, containing class 1 carcinogen Aspergillus flavus, which is harmful to the human body. Therefore, all types of food once moldy, should be avoided.
